Development and initial testing of the self‐care of chronic illness inventory

Development and psychometric evaluation of the self-care of informal caregivers inventory

Background

In recent years, a growing body of literature on informal caregivers' health and well-being has emerged, highlighting the need for a tool to measure their self-care practices.

Objective

The aim of the study was to develop a theory-based instrument measuring the self-care behaviors of informal caregivers and test its psychometric properties.

Design

The initial phase of instrument development entailed a detailed, six-step process (conceptualization, theoretical adaptation, back-translation and cultural adaptation, cognitive interviewing, item enhancement, and content validity), followed by formal psychometric testing (participant engagement, validity, internal consistency reliability, test-retest reliability).

Setting

Study conducted at a hospital located in Tehran, Iran.

Participants

A sample of 234 informal caregivers of cancer outpatients receiving treatment in oncology wards was enrolled. Caregivers had to be 18 years or older, recognized as the primary caregiver by the patient, and willing to provide informed consent.

Methods

The Self-Care of Informal Caregivers Inventory items comprise three dimensions: self-care maintenance (11 items), self-care monitoring (7 items), and self-care management (9 items), which achieved a content validity index rating of 100 % in a panel of experts. Data were collected from caregivers during routine clinic visits. Construct validity was verified through exploratory structural equation modelling and reliability was verified using Cronbach's α and multidimensional model-based reliability. Test-retest reliability was evaluated using the Intraclass Correlation Coefficient.

Results

All three dimensions showed good model fit indices (self-care maintenance: Comparative Fit Index = 1.00, Tucker-Lewis Index = 0.99, Root Mean Square Error of Approximation = 0.044; self-care monitoring: Comparative Fit Index = 1.00, Tucker-Lewis Index = 1.00, Root Mean Square Error of Approximation = 0.027; self-care management: Comparative Fit Index = 0.99, Tucker-Lewis Index = 0.99, Root Mean Square Error of Approximation = 0.048) and Cronbach's α of 0.88, 0.88, and 0.91, respectively. The overall multidimensional model-based reliability was 0.93. The Intraclass Correlation Coefficient values for the three dimensions were 0.94, 0.60, and 0.51, respectively.

Conclusion

Preliminary testing provides support for use of the Self-Care of Informal Caregivers Inventory in research. Using this theory-based instrument to assess the self-care practices of informal caregivers can assist in identifying topics to discuss and opportunities for guidance.

Psychometric Testing of the Cross-Culturally Adapted Thai Version of the Caregiver Self-Efficacy in Contributing to Patient Self-Care Scale in Caregivers of Patients With Chronic Illnesses

AIM

To evaluate the psychometric properties of the Caregiver Self-Efficacy in Contributing to Patient Self-Care Scale (CSE-CSC).

BACKGROUND

The CSE-CSC scale was developed congruently with the Caregiver Contribution to Self-Care of Patient with Chronic Illness Inventory (CC-SC-CII) to assess caregiver self-efficacy (CSE), the motivation factor of caregiving. Its applicability in Asian populations, including Thailand, was limited.

METHODS

Psychometric tests were guided by COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) principles. This included translating the English version into Thai, following the principles of good practice for the translation and cultural adaptation process for patient-reported outcome (PRO) measures. Nine nursing experts evaluated the content validity. The analysis included caregivers of patients with chronic conditions from 16 primary care centres in Thailand. We tested the structural validity using exploratory factor analysis (EFA), confirmatory factor analysis (CFA) and concurrent validity for CC-SC-CII-v2. We tested the scale's reliability with methods for multidimensional and unidimensional constructs, the intraclass correlation coefficients (ICCs) and measurement error variance.

RESULTS

Kappa coefficient (k = 1.00) indicated the scale's excellent content validity. The final analysis included a total of 407 samples. The EFA with the first split-half subsample (n = 194) extracted a two-dimensional structure. One reflected CSE in Maintenance and Monitoring behaviour and another captured CSE in Management behaviour. CFA with the second split-half subsample (n = 213) and the overall sample (n = 407) supported the scale's bidimensional model with high factor loadings. Each dimension and the overall CSE-CSC scale positively correlated with each scale and the overall CC-SC-CII-v2. McDonald's ω and Cronbach's α (both ranged from 0.91-0.94) indicated excellent internal reliability. Test-retest reliability showed ICCs between 0.95 and 0.96. Measurement error yielded satisfactory results.

CONCLUSION

Testing of the Thai CSE-CSC scale supported validity and reliability, indicating that the scale can apply to Thai caregivers. This scale can be used in clinical practice and research to evaluate CSE in contribution to patient self-care.

A Culturally Sensitive Mobile App (DiaFriend) to Improve Self-Care in Patients With Type 2 Diabetes: Development Study

BACKGROUND

Mobile apps designed with cultural sensitivity have demonstrated higher user acceptability and greater effectiveness in enhancing self-care skills. However, a significant gap exists in developing such apps for specific populations, such as Portuguese Americans living in southern Massachusetts, home to the second-largest Portuguese community in the United States. This group possesses unique cultural traditions, particularly in dietary practices, including a tendency toward high carbohydrate intake. Tailoring diabetes self-care apps to address these specific cultural requirements could substantially improve diabetes management within this population.

OBJECTIVE

The aim of this app development project was to develop a prototype diabetes management app for Portuguese Americans with type 2 diabetes mellitus using the design thinking methodology, incorporating user-centered design principles and cultural sensitivity. This paper describes the phase-2 results, focusing on app design and development.

METHODS

Phase 2 of this app development project adhered to the design thinking methodology delineated by the Hasso Plattner Institute of Design at Stanford University, focusing on 2 critical steps: ideation and prototyping. This phase started in March 2022 and continued until April 2024. The project was driven by a multidisciplinary team consisting of 2 nurse educators; an app development specialist; and 2 graduate research assistants from the university's Computer and Information Sciences Department, both well-versed in mobile app development. Data collected during phase 1, which will be published separately, informed the app design and development process.

RESULTS

The prototype of the DiaFriend app (version 1) was designed and developed. The app comprises five features: (1) blood glucose monitoring, (2) weight tracking, (3) carbohydrate tracking, (4) exercise log, and (5) medication reminder. The carbohydrate tracking feature was explicitly tailored to correspond to Portuguese food culture. This paper presents the front-end interface flowchart, demonstrating how the user navigates through each screen. It also discusses the challenges faced during the backend development, such as data not being able to be stored and retrieved.

CONCLUSIONS

The DiaFriend app (version 1) distinguishes itself from conventional diabetes self-care apps through its emphasis on cultural sensitivity. The development of this app underscores the importance of cultural considerations in health informatics. It establishes a foundation for future research in developing and evaluating culturally sensitive mobile health apps. The adaptation of such technologies has the potential to enhance self-care practices among Portuguese Americans with type 2 diabetes mellitus, with improved glycated hemoglobin levels as a potential outcome. The last step of the design thinking methodology, testing the app, will be conducted in phase 3 and the results will be published elsewhere.

Psychometric testing of the Thai version of Caregiver Contribution to Self-Care of Chronic Illness Inventory version 2

AIM

To assess the psychometric properties of the Thai version of Caregiver Contribution to Self-Care of Chronic Illness Inventory version 2 (CC-SC-CII-v2) among primary caregivers of individuals with any single or multiple chronic illnesses.

BACKGROUND

The instrument encompasses three scales that evaluate Caregiver Contribution to Self-Care (CC-SC) Maintenance, Monitoring and Management.

METHODS

The English version CC-SC-CII-v2 was translated and adapted for Thai context, and a cross-sectional multicenter study involved 430 caregivers from 16 primary care centres in Thailand. Structural validity, internal consistency reliability and test-retest reliability were examined.

RESULTS

The original two-factor CC-SC Maintenance scale required a re-specified model for good fit, while the CC-SC Monitoring and CC-SC Management scales fit well. The simultaneous model of three scales demonstrated satisfactory fit. The CC-SC Maintenance and CC-SC Management scales both had a composite reliability index of 0.85, with omega coefficients of 0.86 and 0.83, respectively. CC-SC Monitoring had an alpha coefficient of 0.89. The intraclass correlation coefficients ranging from 0.84 to 0.91, indicating good test-retest reliability.

CONCLUSION

The Thai CC-SC-CII-v2 is a valid and reliable instrument that can provide clinicians and investigators with an evaluation of the contributions of caregivers to the self-care of patients with chronic illnesses.

Measuring Self-Care: A Description of the Family of Disease-Specific and Generic Instruments Based on the Theory of Self-Care of Chronic Illness

BACKGROUND

In recent years, there has been an exponential increase in attention paid to the patient-reported outcome of self-care. Many investigators have used one of the families of self-care instruments freely available on the website www.self-care-measures.com. These self-care measures have been translated into many languages, which are also available on the website. The measures include both disease-specific and generic instruments, which are based on a common theoretical framework, the Middle Range Theory of Self-Care of Chronic Illness.

PURPOSE

The purpose of this article is to illustrate similarities among the instruments and to standardize their scoring, analysis, and use. We describe the Self-Care of Heart Failure Index, the Self-Care of Coronary Heart Disease Inventory, the Self-Care of Hypertension Inventory, the Self-Care of Diabetes Inventory, the Self-Care of Chronic Obstructive Pulmonary Disease Inventory, the Self-Care of Chronic Illness Inventory, and the Self-Care Inventory. Detailed guidance on scoring, translation, and analysis is provided. Complementary measures of self-care self-efficacy and those used to measure caregiver contributions to patient self-care are briefly described.

CONCLUSIONS

Many of the common questions of instrument users are answered in this article. Following this guidance will facilitate consistent use of the instruments, which will enable users to compare their results to those of others worldwide and facilitate future reviews and meta-analyses.Clinical ImplicationsThis review, emphasizing standard scoring and interpretation, is useful for clinicians and researchers across various populations and settings.

Path analysis of self-care amongst community-dwelling pre-ageing and older adults with chronic diseases: A salutogenic model

With the trend towards ageing population globally, the salutogenic model can be integrated in interventions for pre-ageing and older adults to better support healthy ageing. However, there is limited research examining the salutogenic model's pathway amongst pre-ageing and older adults. Hence, this study aims to investigate pathways of the salutogenic model amongst pre-ageing and older adults with chronic diseases. Two hundred and eight pre-ageing and older adults were recruited from 11 Senior Activity Centres in Singapore. Data was collected using a self-reported questionnaire and analysed using path analyses. The indirect pathway from Subjective Cognitive Complaints to self-care abilities via sense of coherence and health practices were significant. Participants with higher sense of coherence may have increased capacities to execute more complex forms of self-care. Future interventions integrating the salutogenic model could enhance pre-ageing and older adults' self-care abilities to cope with chronic diseases and contribute to healthy ageing.

Self-care in patients affected by inflammatory bowel disease and caregiver contribution to self-care (IBD-SELF): a protocol for a longitudinal observational study

INTRODUCTION

Supporting patient self-care and the contribution of their caregivers is crucial in chronic illness care. Inflammatory bowel disease (IBD) is a chronic condition whose prevalence is expected to double, especially in Western countries. IBD symptoms can negatively impact patients' well-being, causing high anxiety, depression, stress and reduced quality of life. These symptoms also affect the health of family members and friends, who often take on caregiving roles during exacerbations. Knowledge about self-care in IBD (IBD-SELF) is limited, and few studies have explored this context. This paper outlines a research protocol for a multicentre longitudinal study to investigate patient self-care and caregiver contributions to IBD-SELF.

METHODS AND ANALYSIS

A sample of 250 consecutive patients diagnosed with IBD and their caregivers will be recruited from 9 dedicated IBD units in northern, central and southern Italy during outpatient visits. Data collection will occur at baseline, 6 and 12 months after enrolment. Multivariable regressions, path analyses and structural equation models will identify predictors (eg, health literacy, caregiver burden and depression) and outcomes (use of healthcare services, disease severity and quality of life) of self-care and caregiver contributions. Dyadic analyses will control for the interdependence of dyad members.

ETHICS AND DISSEMINATION

Ethical approval was obtained from the Territorial Ethics Committee (Lazio 3) N. 0023486/23 and registered on ClinicalTrials.gov (Identifier number: NCT06015789). This study will enhance our understanding of the self-care process in the patient-caregiver dyad in IBD, aiding the design of future educational interventions and promoting greater patient and caregiver involvement in the care pathway.

Generic and disease-specific self-care instruments in older patients affected by multiple chronic conditions: A descriptive study

AIMS

To describe and compare generic and disease-specific self-care measures in patients with multiple chronic conditions (MCCs) in the three dimensions of self-care maintenance, monitoring, and management.

DESIGN

Multicentre cross-sectional study.

METHODS

Patients aged 65 and over with MCCs. We used Self-Care of Chronic Illness Inventory to measure generic self-care, Self-care of Diabetes Inventory to measure self-care in diabetes mellitus, Self-Care of Heart Failure (HF) Index to measure self-care in HF, and Self-Care of Chronic Obstructive Pulmonary Disease Inventory to measure self-care in chronic lung diseases.

RESULTS

We recruited 896 patients. Multimorbid patients with diabetes had lower scores on the self-care maintenance scale, and diabetic patients in insulin treatment on the generic management scale than on the disease-specific instrument. Multimorbid patients with HF or chronic lung diseases scored higher on generic self-care maintenance and monitoring scales than disease-specific ones. There was a partial consistency between the generic and disease-specific self-care maintenance and management. Inadequate behaviours were recorded in disease-specific self-care monitoring rather than generic ones.

CONCLUSIONS

Older patients affected by MCCs scored differently in the generic and disease-specific instruments, showing inadequate self-care in some of the three self-care dimensions.

IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE

The choice between generic and disease-specific instruments to use in clinical practice and research should be made considering the specific aims, settings, patients characteristics, and knowledge of the different performance of the instruments by users.

IMPACT

No study has described and compared generic and specific self-care measures in patients affected by MCCs. Knowing these differences can help nurses choose the most suitable measure for their aims, context, and patients and plan generic and disease-specific self-care educational interventions for those behaviours in which MCCs patients perform poorly.

PATIENT CONTRIBUTION

Patients were informed about the study, provided informed consent, and answered questionnaires through interviews.

Effectiveness of a phone-based support program on self-care self-efficacy, psychological distress, and quality of life among women newly diagnosed with breast cancer: A randomized controlled trial

PURPOSE

This study aimed to determine the effectiveness of a Phone-Based Support Program (PBSP) for newly diagnosed women with breast cancer.

METHODS

A two-group repeated measures randomized controlled trial was designed. Participants included 94 patients aged 18-60 years who were newly diagnosed with breast cancer and undergoing chemotherapy in a tertiary hospital in China. They were randomly assigned to the intervention and the control groups. Participants in the intervention group were enrolled in a four-session PBSP, consisting of four interactive sections: learning, discussion, ask-the-expert, and personal stories, plus the routine care. Outcomes included patients' self-care self-efficacy, psychological distress (including symptom distress, anxiety, and depression), and quality of life. These were assessed at three time points: pre-intervention (T1), post-intervention (T2), and follow-up (T3) by using the self-care self-efficacy scale, the M.D. Anderson Symptom Inventory, the hospital anxiety and depression scale, and the global health status scale.

RESULTS

After completion of the intervention, participants in the intervention group had significantly (p < .001) higher self-care self-efficacy (T2: Mdiff = 11.49, T3: Mdiff = 22.33), better quality of life (T2: Mdiff = 8.18, T3: Mdiff = 17.19), lower symptom distress (T2: Mdiff = -26.68, T3: Mdiff = -54.76), less anxiety (T2: Mdiff = -2.52, T3: Mdiff = -5.11), and less depression (T2: Mdiff = -3.61, T3: Mdiff = -6.71) than those in the control group.

CONCLUSION

These findings indicate that the PBSP is effective. Healthcare professionals, especially nurses, could utilize it to enhance self-care self-efficacy and quality of life, as well as decrease psychological distress among women newly diagnosed breast cancer.

Body listening in the link between symptoms and self-care management in cardiovascular disease: A cross-sectional correlational descriptive study

OBJECTIVE

The aim of this study was to quantify relationships among symptoms, interoceptive sensibility (i.e. the conscious level of sensing, interpreting and integrating signals from the body), and self-care management behaviors (i.e. the response to symptoms when they occur) among adults with cardiovascular disease. We hypothesized that better interoceptive sensibility would increase the positive behavior-driving effects of symptoms on self-care management.

METHODS

Adult patients with cardiovascular disease who experienced recent symptoms were recruited to participate in this cross-sectional correlational descriptive study. Patient-Reported Outcomes Measurement Information System measures were used to capture dyspnea, pain interference, fatigue, sleep disturbances, nausea and vomiting, anxiety and depressive symptoms. Interoceptive sensibility was measured using the Multidimensional Assessment of Interoceptive Awareness Version 2. The Self-Care of Chronic Illness Inventory was used to measure self-care management. Network analysis was used to identify domains of interoceptive sensibility that were most central. Linear regression with interaction terms was used to test the moderating effect of interoceptive sensibility on the relationship between symptoms and self-care management.

RESULTS

The age of participants in the sample (n = 387) ranged from 18 to 88 years, a slight majority (53.5 %) were female, and a majority were Caucasian (66.4 %) or African American (32.0 %). Hypertension was the most common disorder (n = 238 (61.5 %)), followed by rhythm disorders (n = 124 (32.0 %)), coronary artery disease (n = 94 (24.3 %)), heart failure (n = 89 (23.0 %)), valve disease (n = 69 (17.8 %)), stroke (n = 62 (16.0 %)) and peripheral vascular disease (n = 49 (12.7 %)). Based on network analysis, body listening (i.e. active listening to the body for insights) was the most central interoceptive domain, and distracting (i.e. tendency to ignore or distract oneself from sensations of discomfort) was the least central. Noticing (i.e. greater awareness of body sensations), distracting, and body listening were significant in moderating relationships between dyspnea, sleep disturbances and anxiety and the outcome of self-care management behaviors (all p < 0.001). Better noticing and body listening were associated with better self-care management across symptoms, whereas ignoring or distracting oneself from discomfort was associated with worse self-care management behaviors.

CONCLUSION

Among adults with cardiovascular disease, interventions designed to augment the identified interoceptive sensibility domains like body listening, and mitigate the tendency to ignore or distract oneself from discomfort may support adults with cardiovascular disease through the development of future interventions that optimize patient behaviors in response to symptoms when they occur.

This article aims to present a thorough yet brief review of methods that can be employed to build the emotional wellness of chronic patients.

RECENT FINDINGS

The mental health care strategies include resilience-building, coping skills training, professional counseling, and lifestyle adaptations. Additionally, the article highlights the efficacy of several modern interventions, such as mindfulness-based therapies, cognitive behavioral therapy, eye movement desensitization, and recovery from stress therapy. The global burden of chronic illness emphasizes the pressing need to mitigate mental health problems among chronic patients. By providing actionable insights, our study clears the path for targeted interventions and holistic approaches for chronic disease patients. Moreover, the article suggests to policymakers and clinicians the need for collaboration and multifaceted interventions.

Psychometric Testing of the Thai Version of Self-Care of Chronic Illness Inventory Version 4c in Patients With Stroke

BACKGROUND

Self-Care of Chronic Illness Inventory version 4c is a non-disease-specific self-care measure used in individuals with multiple chronic conditions. This instrument may be applied to patients with specific diseases such as stroke.

OBJECTIVE

The aim of this study was to evaluate the psychometric properties of the Thai version of the Self-Care of Chronic Illness Inventory version 4c in patients with stroke.

METHODS

This multicenter, cross-sectional study adhered to the COSMIN (Consensus-based Standards for the Selection of Health Measurement Instruments) guidelines and enrolled patients with stroke from 16 primary care centers in southern Thailand. Structural validity was assessed using confirmatory factor analysis, internal consistency reliability using Cronbach α coefficient and global reliability index, and test-retest reliability using intraclass correlation coefficients.

RESULTS

The final analysis included a total of 350 participants. Confirmatory factor analysis supported the 2-factor Self-Care Maintenance scale structure, although the item allocation to the dimensions differed from that of the original model. The Self-Care Monitoring scale demonstrated a 1-factor structure with permitted residual covariance. The Self-Care Management scale maintained a 2-factor structure, similar to that of the original model. Simultaneous confirmatory factor analysis of the combined items supported the general model with the 3 scales. The Self-Care Maintenance scale exhibited marginally adequate α (0.68) and ω (0.66) coefficients, and an adequate composite reliability index (0.79). The other 2 scales demonstrated adequate α (range, 0.79-0.86), ω (range, 0.75-0.86), and composite reliability (range, 0.83-0.86) indices. Intraclass correlation coefficients showed adequate test-retest reliability for all scales (range, 0.76-0.90).

CONCLUSIONS

The generic self-care measure, Self-Care of Chronic Illness Inventory version 4c, demonstrated strong psychometric properties in patients with stroke. This instrument may be a valuable tool for assessing stroke self-care in Thailand.

Psychometric Analysis of the Health Self-Care Neglect Scale

OBJECTIVES

The Health Self-Care Neglect (HSCN) scale is a measure of self-care neglect developed for use in informal caregivers, where self-care is defined as behaviors undertaken to maintain health. There was no formal psychometric analysis of the scale, so we tested a 9-item, dichotomous-response version of the HSCN scale in a sample of 250 informal caregivers of adults with chronic heart failure.

METHODS

As the indicators of self-care neglect were considered formative (influencing the latent variable directly) rather than reflective (influenced by the latent variable), we used a procedure for the specification of formative measurement models. First, maximally correlated composites of indicators were identified for the latent variable, and optimal scoring weights were developed. Then, the reflective factor was tested with confirmatory factor analysis, and longitudinal invariance of the factorial structure was tested by introducing model constraints. Reliability was assessed with composite reliability model-based estimates. Concurrent validity was assessed by correlating the HSCN scale total score with the maintenance scale score of the Self-Care Inventory.

RESULTS

Strict invariance, the highest level possible, was achieved. Reliability was 0.81 at baseline. Concurrent validity was demonstrated ( r = -0.475, P < .0001).

CONCLUSION

The results of this analysis indicate that the HSCN scale is reliable, stable, and valid as a measure of health self-care neglect when tested in a sample of caregivers. The HSCN scale measures the successful performance of self-care, whereas existing measures of self-care reflect intention. Understanding both intention and behavior is useful, so we recommend using the HSCN scale in addition to existing measures of self-care.

The role of nurse-patient mutuality on self-care behaviours in patients with chronic illness

AIM

To examine the role of nurse-patient mutuality on three self-care behaviours in chronic illness patients.

DESIGN

A cross-sectional multi-centre study was conducted.

METHODS

Mutuality was measured with the Nurse-Patient Mutuality in Chronic Illness scale which has the dimensions of developing and going beyond, being a point of reference and deciding and sharing care, and self-care was measured with the Self-care of Chronic Illness Inventory (SC-CII). Multivariable linear regression analyses were used to assess the contribution of three dimensions of mutuality on self-care maintenance, monitoring and management behaviours controlling for patient gender, age, education, number of medications, and presence of a family caregiver.

RESULTS

The sample included 465 inpatients and outpatients with at least one chronic illness. The three dimensions of mutuality had different roles in their influence on the three dimensions of self-care. Developing and going beyond was significantly associated with self-care maintenance and self-care monitoring behaviours. Point of reference was significantly associated with self-care maintenance behaviour. Deciding and sharing care was significantly associated with self-care monitoring and self-care management behaviours.

CONCLUSION

The mutuality between nurse and patient may be a novel area of research to support and improve patient self-care behaviours with implications for clinical practice and education.

IMPLICATION FOR PROFESSION AND PATIENT CARE

Mutuality between nurse and patient increases patient engagement, symptom recognition, decision-making process and patient-centred approach favouring the development of self-care behaviours.

IMPACT

Mutuality between nurse and patient is a new concept and its association with the patient outcomes could bring relevance to the nursing profession. Self-care behaviours are important in the management of chronic diseases, but are difficult to perform. Mutuality between nurse and patient influences the three different behaviours of self-care in chronic illness, for this reason it is important to increase the level of mutuality in this dyad.

REPORTING METHOD

STROBE checklist for cross-sectional studies was followed in this study.

Health Literacy and Self-Care in Patients with Chronic Illness: A Systematic Review and Meta-Analysis Protocol

Self-care plays a critical role in symptom recognition, management, and risk factor modification for patients with chronic illnesses. Despite its significance, self-care levels in this population are generally poor. Health literacy (HL) is pivotal for promoting effective self-care, yet the association across specific chronic illnesses remains fragmented and conflicting. Therefore, a systematic review and meta-analysis will be conducted. Inclusion criteria encompass quantitative studies involving adult patients with at least one chronic illness reporting on the association between a measure of HL and one or more elements of self-care behaviors as outcomes. Databases to be searched include PubMed, CINAHL, APA PsycINFO, Embase, Web of Science, and Cochrane Central Register of Controlled Trials. The studies will undergo risk of bias and certainty of evidence assessment using ROBINS-E and GRADE. Extracted data will include authors, publication date, aim(s), study location, design, sample characteristics, chronic illness type, study length, HL, and self-care measures. Understanding the link between HL and self-care can aid healthcare providers in implementing strategies to enhance health-promoting behaviors, contributing valuable insights to the scientific community and fostering nuanced discussions. This protocol ensures methodological transparency, stimulates discourse, and paves the way for informed interventions to improve overall health outcomes.

Development and psychometric testing of the Self-Care of Stroke Inventory

PURPOSE

To develop and evaluate the psychometric properties of the Self-Care of Stroke Inventory (SCSI).

MATERIALS AND METHODS

A cross-sectional, instrument development and the psychometric testing study was conducted. A 23-item self-report Self-Care of Stroke Inventory with 3 separate scales was developed. This study involved three stages: (a) Initial items generation; (b) Content and face validation; (c) Psychometric properties evaluation. The SCSI was validated by content validity, construct validity, convergent validity, internal consistency, and test-retest reliability.

RESULTS

From the initial 80-item pool, 24 items of 3 scales in the SCSI were retained by the expert consultation and item analysis. The scale's content validity was 0.976, 0.966, and 0.973. The EFA showed the total variance explained by the 3 scales of the SCSI were 73.417%, 74.281%, and 80.207%, respectively. The models of the 3 scales identified by EFA were all confirmed by the CFA. The SCSI scale shows evidence of good convergent validity. Cronbach's αs were 0.830, 0.930, and 0.831. Test-retest reliability of the SCSI was excellent, with an intraclass correlation coefficient of 0.945, 0.907, and 0.837.

CONCLUSIONS

The final 23-item SCSI presents good psychometric properties and can be used to explore the self-care of stroke in community settings.IMPLICATIONS FOR REHABILITATIONThis study developed and validated the Self-Care of Stroke Inventory (SCSI).The SCSI contains the following 3 scales: the Self-care Maintenance of Stroke scale, the Self-care Monitoring of Stroke scale, and the Self-care Management of Stroke scaleThe 23-item SCSI demonstrated strong psychometric properties.The SCSI may be used to develop future programmes to promote self-care for stroke survivors and improve their rehabilitation outcomes.

Impact of caregiver relationship on self-care in patients with Parkinson's disease: A cross-sectional study using Riegel's theory of self-care of chronic illness

AIMS

To explore how the characteristics of patients and caregivers affect self-care in patients with Parkinson's disease (PD).

DESIGN

A multicentre cross-sectional study.

METHOD

We followed the STROBE checklist. Parkinson's disease patients aged 50 years and older and their caregivers were recruited from two tertiary hospitals and the Korean Parkinson's Disease Association website. Patient characteristics, including social support, relationship quality with caregivers, self-care efficacy and self-care, were analysed. Caregiver characteristics were also evaluated, including caregiving duration, social support, relationship quality with patients, contribution to patients' self-care efficacy and contribution to patients' self-care.

RESULTS

The characteristics of patients and caregivers (103 pairs) were hierarchically regressed into patient self-care domains (maintenance, monitoring and management). Most patients and caregivers gave a self-care efficacy and self-care management rating of moderate. In three regression models, patient self-care efficacy was positively related to three domains of patient self-care. Self-care maintenance decreased as patients' disease duration increased. Self-care monitoring was positively related to the education level of patients and caregiving duration. Self-care management showed an inverse relationship with caregiving duration and a positive relationship with caregiver contribution.

CONCLUSION

Self-care efficacy was important in promoting PD patients' self-care maintenance, monitoring and management. The contributions of caregivers were also critical in increasing PD patients' self-care management.

IMPLICATIONS FOR THE PROFESSION AND PATIENT CARE

To increase patients' self-care efficacy and self-care, educational interventions containing information about the disease, symptom management, and problem-solving should be implemented. Since caregivers are deeply involved in patients' self-care, educational interventions for caregivers should also be provided.

IMPACT

This study closed the literature gap by examining the self-care efficacy and self-care of Korean PD patients. Findings demonstrated the importance of caregiver roles on patients' self-care and health.

PATIENT OR PUBLIC CONTRIBUTION

Two tertiary hospitals and the Korean Parkinson's Disease Association assisted during the recruitment process.

How do patients with rheumatoid arthritis perceive their self-care and self-care support? A mixed-method study

AIM

To explore self-care and needs and preferences towards tailored self-care support of patients with rheumatoid arthritis at the outpatient clinic.

DESIGN

A sequential explanatory mixed method design.

METHODS

The Self-Care of Chronic Illness Inventory questionnaire, two focus groups and six semi-structured interviews were conducted between November 2021 and April 2023. Questionnaires of 107 patients were descriptively analysed. Subsequently, 11 patients and 2 healthcare professionals participated in the focus groups and 6 patients in the interviews, which were thematically analysed.

RESULTS

Quantitative and qualitative data corresponded and showed that patients perform various self-care activities at an adequate level and have strategies to exert control and reduce symptoms. One key theme emerged: 'Not only being the person with rheumatoid arthritis' (RA) as patients primarily aim to get on with their lives. Nine subthemes covered self-care activities for maintaining health including staying physically active, finding the right medication and dose and adapting their diet. Patients differed in how they self-monitored their symptoms. Recognizing symptoms and finding strategies to manage symptoms included the process of body listening in which patient seek and try different strategies to find what works for them and incorporate routines. Patients experienced positive effects of a warm or cold environment. Patients felt the need for practical and emotional support from others and preferred having credible information.

CONCLUSION

Patients perform adequate self-care including a diversity of self-care activities to get on with their lives and have strategies to reduce and control the symptoms and impact of RA.

IMPLICATIONS

Tailoring self-care support to patients' individual needs and preferences is necessary to help patients cope with the erratic nature of the disease and maintain their quality of life. Healthcare providers need to provide practical and emotional support and use credible information to allow patients to make self-care decisions to manage their lives.

REPORTING METHODS

Quantitative finding are reported according to the STROBE guidelines and qualitative finding are reported according to the COREQ guidelines.

WHAT DOES THIS PAPER ADD

Patients perform various self-care activities at an adequate level and have strategies to exert control and reduce symptoms. Patients primarily aim to continue their lives and not being seen as the person with rheumatoid arthritis. Healthcare professionals need to provide practical and emotional support and use credible information to inform patients' self-care decision-making.

Patterns of self-care decision-making and associated factors: A cross-sectional observational study

OBJECTIVE

The aim of this study was to identify for the first time patterns of self-care decision-making (i.e. the extent to which participants viewed contextual factors influencing decisions about symptoms) and associated factors among community-dwelling adults with chronic illness.

METHODS

This was a secondary analysis of data collected during the development and psychometric evaluation of the 27-item Self-Care Decisions Inventory that is based on Naturalistic Decision-Making (n = 430, average age = 54.9 ± 16.2 years, 70.2 % female, 87.0 % Caucasian, average number of chronic conditions = 3.6 ± 2.8). Latent class mixture modeling was used to identify patterns among contextual factors that influence self-care decision-making under the domains of external, urgency, uncertainty, cognitive/affective, waiting/cue competition, and concealment. Multivariate multinomial regression was used to identify additional socio-demographic, clinical, and self-care behavior factors that were different across the patterns of self-care decision-making.

RESULTS

Three patterns of self-care decision-making were identified in a cohort of 430 adults. A 'maintainers' pattern (48.1 %) consisted of adults with limited contextual influences on self-care decision-making except for urgency. A 'highly uncertain' pattern (23.0 %) consisted of adults whose self-care decision-making was largely driven by uncertainty about the cause or meaning of the symptom. A 'distressed concealers' pattern (28.8 %) consisted of adults whose self-care decision-making was highly influenced by external factors, cognitive/affective factors and concealment. Age, education, financial security and specific symptoms were significantly different across the three patterns in multivariate models.

CONCLUSION

Adults living with chronic illness vary in the extent to which contextual factors influence decisions they make about symptoms, and would therefore benefit from different interventions.

Spanish version of the Self-Care of Chronic Illness Inventory: A validation study amongst community-dwelling older adults with chronic multimorbidity

AIM

To psychometrically assess the Spanish version of the Self-Care of Chronic Illness Inventory (SC-CII-Sp) in community-dwelling older adults with chronic multimorbidity.

DESIGN

A methodological study.

METHOD

A total of 1260 older adults participated in the study between May 2020 and February 2022. The data were analysed using SPSS Statistics® 26 and AMOS® 24. The items' content validity index and the Fleiss' kappa were calculated to assess the SC-CII-Sp's content validity. Convergent validity was assessed by calculating the Pearson correlation coefficient between the participants' scores on the SC-CII-Sp and their scores on the Spanish Chronic Disease Self-Efficacy scale (SCD-SE). Construct validity was tested by performing a confirmatory factor analysis (CFA). The SC-CII-Sp's reliability was tested by computing the Cronbach's alpha.

RESULTS

The SC-CII-Sp showed good content and convergent validity. The CFA showed that the SC-CII-Sp has three sub-scales. The 8-item Self-Care Maintenance sub-scale has good internal consistency and is comprised of two dimensions: illness-related and health-promoting behaviour. The Self-Care Monitoring sub-scale had excellent internal consistency and its five loaded items belonged to a single dimension. The 6-item Self-Care Management sub-scale has adequate internal consistency and two dimensions: autonomous and consulting behaviour.

CONCLUSION

The Spanish version of SC-CII is a valid and reliable instrument to be used in the assessment of self-care behaviours amongst Spanish-speaking, community-dwelling older adults with chronic multimorbidity.

IMPLICATIONS FOR THE PROFESSION

Nurses need valid and reliable tools to assess self-care behaviours in Spanish-speaking community-dwelling older adults with chronic multimorbidity. This study provides a 19-item tool that allows for the comprehensive evaluation of self-care behaviours in healthy and ill states.

IMPACT

Using the SC-CII-Sp in clinical or research settings could help nurses to examine the effects of different interventions on self-care behaviours amongst Spanish-speaking, community-dwelling older adults with chronic multimorbidity.

Urban-rural differences in associations among perceived stress, resilience and self-care in Chinese older adults with multiple chronic conditions

BACKGROUND

Social determinants of health (SDH) are mainly comprised of structural and intermediary domains. Emerging evidence suggests that the burden of multiple chronic conditions (MCCs) in older adults is exacerbated by structural determinants (e.g. low income and low education). However, less attention was paid to the intermediary determinants (i.e. material circumstances, psychosocial factors and behavioural factors) of MCCs.

OBJECTIVES

To investigate the associations among perceived stress, resilience and self-care in Chinese older adults with MCCs by comparing urban and rural groups.

METHODS

A convenience sample (125 and 115 participants from urban and rural settings, respectively) of Chinese older adults with MCCs was enrolled between January and April 2022. Hierarchical multiple regression analyses and propensity score weights were used to determine the associations among perceived stress, resilience and self-care.

RESULTS

Hypothesis 1 regarding the negative associations between perceived stress and self-care was fully supported in the rural group. However, for the urban group, the negative association was only supported for the relationship between MCCs-related perceived stress and self-care maintenance. Hypothesis 2 was fully supported regarding the positive associations between resilience and the three components of self-care in both groups, although the relationship between resilience and self-care monitoring was marginally significant in the urban group. Hypothesis 3 regarding the moderating effect of resilience was only supported in the relationship between general perceived stress and self-care monitoring in the rural group. After adding the propensity score weights, the moderating effect was no longer statistically significant in the rural group.

CONCLUSIONS

The urban-rural disparities in the Chinese context might largely be attributed to the complex interactions of the structural determinants and intermediary determinants. Findings can inform the development of culturally tailored interventions to promote self-care and reduce urban-rural disparities for Chinese older adults with MCCs.

IMPLICATIONS FOR PRACTICE

With the increasing number of older adults in China who are living with multiple chronic conditions and the call for effective interventions to improve their health outcomes, current findings can inform the development and implementation of nurse-led culturally tailored interventions to promote self-care and reduce urban-rural disparities for Chinese older adults with MCCs.

Effects of a Phone-Based Support Program for Women With Breast Cancer Undergoing Chemotherapy: A Pilot Study

Introduction

The increasing number of women with breast cancer undergoing chemotherapy may result in long-lasting, adverse physical side effects and reduced quality of life.

Objective

This study aimed to develop and assess the feasibility and preliminary effects of the Phone-Based Support Program for women with breast cancer undergoing chemotherapy. The primary outcome was self-care self-efficacy; secondary outcomes were symptom distress and quality of life.

Methods

This pilot study was conducted at a tertiary hospital in Jiangsu province, China, from February to March 2023. The Phone-Based Support Program was delivered to 20 participants through the smartphone application WeChat, consisting of learning, discussion, ask-the-expert, and personal stories components. Outcome measures were assessed at three time points: preintervention, postintervention, and follow-up.

Results

The Phone-Based Support Program was feasible and could improve self-care self-efficacy, decrease symptom distress, and promote quality of life. The program was well-accepted, and participants engaged actively in the online discussion and sought expert advice.

Conclusions

The Phone-Based Support Program showed feasibility and effectiveness in improving self-care self-efficacy, reducing symptom distress, and enhancing quality of life.

Instruments for measuring self-management and self-care in geriatric patients - a scoping review

Introduction

With demographic changes, prioritizing effective care for geriatric patients to maintain functionality, independence, and quality of life is crucial. Well-developed self-management or self-care abilities, which can be maintained and improved through interventions, are of the utmost importance. To implement these interventions tailored and effectively, a thorough assessment of the individual's self-management and self-care abilities is required.

Objective

This scoping review aimed to identify self-management and self-care instruments suitable for geriatric patients, their underlying theories and definitions of self-management and self-care, and their similarities and differences in item content.

Methods

A systematic search of the PubMed and CINAHL databases was conducted to identify retrievable full-text articles published in English in the medical and nursing fields since the 1970s, which were validated on a sample with an average age of at least 70 years, used generic rather than disease-specific items, and addressed the broad range of self-management and self-care abilities.

Results

Of the 20 included articles, six instruments were identified that were based on different theories and offered varying definitions of self-management or self-care. Despite these differences, all emphasize empowered individuals taking an active role in their care. Most address actual behavior and abilities referring to lifestyle factors and (anticipated) adjustment behavior. However, crucial aspects, such as psychological factors, (instrumental) activities of daily living, and social environment are not fully addressed in these instruments, nor are the types of execution to which the items refer, such as wants, feelings, confidence, or attitudes.

Conclusion

To fully understand how geriatric patients implement daily self-management or self-care, a combination of instruments covering the important factors of self-management and self-care and addressing multiple types of item execution, such as behaviors, abilities, wants, or attitudes, is recommended. This review provides the first comprehensive overview of self-management and self-care instruments suitable for geriatric patients.

The association of resilience with self-care and quality of life in people with chronic obstructive pulmonary disease: A cross-sectional study

AIM

To investigate the association of resilience with self-care and quality of life in people with chronic obstructive pulmonary disease.

DESIGN

Cross-sectional study.

METHODS

Data were collected between February and May 2021. Self-care was measured with the self-care of chronic illness inventory, quality of life was measured with the clinical chronic obstructive pulmonary disease questionnaire and resilience was measured with the resilience evaluation scale. Possible confounders were included (sex, age, smoking, time since diagnosis of chronic obstructive pulmonary disease, educational level, social support and pulmonary function). Multiple regression analysis was performed among the determinants, confounders and both outcomes.

RESULTS

Participants scored fairly well on resilience (mean 22.5). Self-care scored reasonably well (mean maintenance 65.9, mean monitoring 70.9, mean management 59.9 and mean confidence 71.5). Quality of life scored mediocre (mean 2.6). The results of the linear multiple regression were resilience, which is associated with self-care confidence and quality of life when adjusted for possible confounders. This means people with chronic obstructive pulmonary disease with higher resilience have better self-care confidence and higher quality of life. The outcome contributes to strengthening nursing care and further developing nurses' knowledge. The results can contribute to increasing awareness for healthcare professionals that resilience can potentially increase self-care and quality of life.

Self-care nursing assessment: cross-cultural adaptation and validation of the Spanish version of the Self-care of chronic illness inventory

BACKGROUND

Self-care is the primary means of caring for a chronic condition. Therefore, it is necessary to assess it by using a good validity and reliability instrument. The Self-Care of Chronic Illness Inventory (SC-CII) is a generic instrument developed to measure self-care processes behaviors using three separate scales in patients with chronic illness. The original cross-cultural assessment concluded the need for future studies sampling patients from different sites to increase the generalizability of the psychometric evaluation results. It was unclear whether this tool had sound psychometrics properties in the context of Spanish culture. The purpose of this study was to cross-culturally adapt the SC-CII, test its psychometric properties and validate its use among Spanish people with chronic diseases.

METHODS

A cross-cultural translation of the SC-CII was performed from English to Spanish. The psychometric evaluation was conducted in a sample of 350 patients with chronic conditions through a multicenter cross-sectional study based on the STROBE guideline. Data were collected from face-to-face interviews during 2022. Internal validity was assessed with Confirmatory Factor Analysis, internal consistency reliability with Cronbach alpha for unidimensional scales and McDonald's Omega reliability coefficient for multidimensional scales.

RESULTS

Most (63.4%) participants were older adults aged 65 years or older with a mean age of 65.45 ± 14.97. The average number of chronic conditions reported was 2.81%; the most common conditions were hypertension (52.3%), musculoskeletal disorders (46.3%) and diabetes (38.9%). Patients reported adequate self-care behaviors in all three scales of the SC-CII. The Self-Care Maintenance and Management scales were multidimensional, and the Self-Care Monitoring scale was unidimensional. In Confirmatory Factor Analysis, the Self-Care Maintenance and Monitoring scales had satisfactory fit indices. The Self-care Management scale had acceptable fit indices. The Omega reliability coefficient for multidimensional scales was 0.75 (Self-Care Maintenance) and 0.72 (Self-Care Management). The Cronbach alpha coefficient of the Self-Care Monitoring scale was 0.85. Item-total correlations were all significant except one. Test-retest reliability showed an intraclass correlation coefficient of 0.92.

CONCLUSIONS

The SC-CII has appropriate psychometrics characteristics and is a culturally suitable and reliable instrument for assessing to the self-care behaviors of patients with chronic disease in Spain. The scale provides a simple and rapid solution to assess the self-care process.

Patient compliance: A concept analysis

Background

Patient compliance with regimens is one of the most researched and least-understood behavioral concerns in the healthcare profession due to the many meanings employed in multidiscipline over time. Thus, a thorough examination of the idea of patient compliance is necessary.

Objective

This paper aims to explore and identify the essence of the term patient compliance to achieve an operational definition of the concept.

Method

Walker and Avant's eight-step approach was used. A literature search was conducted using keywords of patient compliance AND healthcare profession from five databases: PubMed, Medline, CINAHL, ProQuest, ScienceDirect, and Cochrane database, published from 1995 to 2022.

Results

The attributes of patient compliance include 1) self-care behavior, 2) following health recommendations, and 3) willing collaboration with health professionals. Antecedents of patient compliance were characteristics of therapeutic regimens, communication of health advice, and patients' attitudes toward professional recommendations. Consequences include improved clinical outcomes, quality of life, and lifestyle or behavior modification.

Conclusion

This concept analysis offers a valuable perspective on patient compliance that guides the nursing practice in providing better interventions to promote compliance among patients.

A psychometrics evaluation of the Thai version of Caregiver Contribution to Self-Care of Chronic Illness Inventory Version 2 in stroke caregivers

Objectives

To evaluate the psychometric characteristics of the Thai version of Caregiver Contribution to Self-Care (CC-SC) of Chronic Illness Inventory version 2 (CC-SC-CII-v2) in stroke caregivers.

Methods

We conducted a multicenter, cross-sectional study following the COSMIN guidelines, evaluating validity and reliability of three separate scales, CC-SC Maintenance, CC-SC Monitoring, and CC-SC Management, as well as overall CC-SC-CII-v2. From September to December 2022, we enrolled 422 stroke caregivers from primary care centers in southern Thailand. Structural validity was assessed through confirmatory factor analysis (CFA), while concurrent validity was evaluated using Pearson's correlation r coefficients between CC-SC-CII-v2 and the Caregiver Self-Efficacy in Contributing to Patient Self-Care Scale (CSE-CSC). Internal coherence reliability was assessed using Cronbach's α coefficient, the composite reliability index, and the McDonald's ω coefficient. Additionally, test-retest reliability was assessed with intraclass correlation coefficients (ICCs).

Results

The study included mostly middle-aged women who cared for their parent. CFA supported the two-factor structure of the CC-SC Maintenance and Management scales and the one-factor structure of the CC-SC Monitoring scale. A simultaneous CFA on the combined set of items supported the more general model. The concurrent validity of CC-SC-CII-v2 with CSE-CSC was established (r ranging 0.47-0.65, all P < 0.001). Reliability estimates supported adequate Cronbach's α coefficient (ranging 0.83-0.89), composite reliability (ranging 0.84-0.85), McDonald's ω coefficients (ranging 0.83-0.85), and ICCs (ranging 0.86-0.90) across the three scales.

Conclusions

The Thai CC-SC-CII-v2 demonstrated strong psychometric properties among stroke caregivers. It can be a valuable instrument to investigate the role of caregivers in contributing to stroke patients' self-care in diverse cultural contexts like Thailand.

Validity and Reliability of Caregiver Contribution to Self-Care of Chronic Obstructive Pulmonary Disease Inventory and Caregiver Self-Efficacy in Contributing to Self-Care Scale

The study tested the construct validity and reliability of the Caregiver Contribution to Self-Care of Chronic Obstructive Pulmonary Disease (COPD) Inventory and the Caregiver Self-Efficacy in Contributing to Self-Care of COPD Scale. The two instruments were developed by modifying the Self-Care of COPD Inventory and Self-Care Self-Efficacy Scale in COPD into caregiver versions. The psychometric properties were tested in a convenience sample of 261 informal caregivers of COPD patients recruited in Italy in two cross-sectional studies. Structural validity was tested by confirmatory factor analysis, construct validity by posing several hypotheses, and internal consistency through factor score determinacy and global reliability index for multidimensional scales. In confirmatory factor analysis, the caregiver contribution to self-care maintenance, monitoring and management scales, composing the Caregiver Contribution to Self-Care of COPD Inventory, presented good fit indices. Global reliability indices ranged 0.75-0.88. The caregiver self-efficacy scale presented a comparative fit index of 0.96 and a global reliability index of 0.82. The caregiver contribution to self-care and the caregiver self-efficacy scales correlated moderately among themselves and with the patient versions of the scales, and scores were higher with caregiver-oriented dyadic care types and female caregivers. Our study provides evidence of the two instruments' construct validity and internal consistency.

The influence of dyad sex combination on patient self-care and caregiver contribution to self-care in multiple chronic conditions: An observational study

INTRODUCTION

We know that patient and caregiver sex influence patient self-care and caregiver contribution to self-care in multiple chronic conditions. However, the role of dyad sex combination (e.g., male patient and female caregiver, female patient and male caregiver, male patient and caregiver, and female patient and caregiver) in influencing patient self-care and caregiver contribution to self-care remains unexplored. Our aim was to investigate the relationship between patient and caregiver sex combination and patient self-care and caregiver contribution to self-care in multiple chronic conditions.

DESIGN

Multicentre cross-sectional study.

METHODS

We enrolled patients with multiple chronic conditions and caregiver dyads in outpatient and community settings from April 2017 to December 2019. We used the Self-Care of Chronic Illness Inventory and the Caregiver Contribution to Self-Care of Chronic Illness Inventory that measure, from the patient and caregiver perspective, self-care maintenance (i.e., behaviors to maintain illness stability), self-care monitoring (i.e., monitoring of illness signs and symptoms), and self-care management (i.e., behaviors to manage signs and symptoms). We used multivariate analysis of covariance to evaluate the association between sex and self-care and caregiver contribution to self-care.

RESULTS

We recruited 540 patient-caregiver dyads. Male patients cared by female caregivers performed higher self-care maintenance compared to female patients cared by female caregivers. Female caregivers caring for female patients performed higher caregiver contribution to self-care monitoring compared to male caregivers caring for female or male patients.

CONCLUSIONS

Clinicians should consider the influence of patient and caregiver sex combination on self-care and caregiver contribution to self-care in multiple chronic conditions to provide tailored interventions.

CLINICAL RELEVANCE

Healthcare professionals should consider the patient and caregiver sex combination in the dyad to tailor better interventions aimed at improving patient self-care and caregiver contribution to self-care in multiple chronic conditions.

Spanish version of the self-care self-efficacy scale: A validation study in community-dwelling older adults with chronic multimorbidity

OBJECTIVE

To test the psychometric properties of the Spanish version of the Self-Care Self-Efficacy Scale (SCSES-Sp) in community-dwelling older adults with chronic multimorbidity.

METHODS

A sample of 1013 community-dwelling older adults with chronic multimorbidity participated in an observational cross-sectional study that was carried out in 3 phases.

RESULTS

Confirmatory factor analysis showed that the SCSES-Sp has 4 dimensions: "self-efficacy in self-care behaviours based on clinical knowledge", "self-efficacy in self-care maintenance", "self-efficacy in self-care monitoring", and "self-efficacy in self-care management". A panel of independent experts considered the content of the SCSES-Sp valid. Convergent validity analysis showed moderate-strong correlations between all of the SCSES-Sp's dimensions and the reference criteria chosen. Reliability was good for the SCSES-Sp and all its dimensions. Test-retest reliability analysis showed that the SCSES-Sp was temporally stable.

CONCLUSIONS

The SCSES-Sp is a valid and reliable tool to assess self-efficacy in self-care in Spanish-speaking, community-dwelling older adults with chronic multimorbidity.

Dyadic Archetypes of Patient Self-Care and Caregiver Contribution to Self-Care in Dyads With Multiple Chronic Conditions: An Observational Study

Self-care of multiple chronic conditions (MCCs) and caregiver contribution to self-care have been theorized as dyadic. However, the different dyadic archetypes are still unknown. This cross-sectional study aimed to identify dyadic archetypes related to how in patient-caregiver dyads manage the patient's MCCs and to describe other ways in which the dyadic archetypes differ. A sample of 340 MCCs patient-caregiver dyads was enrolled in outpatient and community settings. Patients had a mean age of 76.7 (±7.3) years and were mostly female (54.5%). Caregivers had a mean age of 54.6 (±15.1) years and were mostly female (71.5%). Four dyadic archetypes were observed: "autonomous," "compensatory," "balanced," and "complementary" care. Clinical programs should consider the different characteristics of dyads to support self-care.

Tools for measuring individual self-care capability: a scoping review

BACKGROUND

Our ability to self-care can play a crucial role in the prevention, management and rehabilitation of diverse conditions, including chronic non-communicable diseases. Various tools have been developed to support the measurement of self-care capabilities of healthy individuals, those experiencing everyday self-limiting conditions, or one or more multiple long-term conditions. We sought to characterise the various non-mono-disease specific self-care measurement tools for adults as such a review was lacking.

OBJECTIVE

The aim of the review was to identify and characterise the various non-mono-disease specific self-care measurement tools for adults. Secondary objectives were to characterise these tools in terms of their content, structure and psychometric properties.

DESIGN

Scoping review with content assessment.

METHODS

The search was conducted in Embase, PubMed, PsycINFO and CINAHL databases using a variety of MeSH terms and keywords covering 1 January 1950 to 30 November 2022. Inclusion criteria included tools assessing health literacy, capability and/or performance of general health self-care practices and targeting adults. We excluded tools targeting self-care in the context of disease management only or indicated to a specific medical setting or theme. We used the Seven Pillars of Self-Care framework to inform the qualitative content assessment of each tool.

RESULTS

We screened 26,304 reports to identify 38 relevant tools which were described in 42 primary reference studies. Descriptive analysis highlighted a temporal shift in the overall emphasis from rehabilitation-focused to prevention-focused tools. The intended method of administration also transitioned from observe-and-interview style methods to the utilisation of self-reporting tools. Only five tools incorporated questions relevant to the seven pillars of self-care.

CONCLUSIONS

Various tools exist to measure individual self-care capability, but few consider assessing capability against all seven pillars of self-care. There is a need to develop a comprehensive, validated tool and easily accessible tool to measure individual self-care capability including the assessment of a wide range of self-care practices. Such a tool could be used to inform targeted health and social care interventions.

Cross-cultural adaptation and psychometric evaluation of the Thai version of Self-Care of Chronic Illness Inventory Version 4.c

Objectives

To translate and validate the Thai Self-Care of Chronic Illness Inventory version 4.c (Thai SC-CII v4.c) in individuals with chronic illnesses.

Methods

A scale translation and cross-sectional validation study was conducted. The English version was translated for Thai involved nine steps: preparation, forward translation, reconciliation, back-translation, back-translation review, harmonization, cognitive debriefing, review of cognitive debriefing and finalization, and proofreading. A cross-sectional study was conducted from July to November 2022 at 16 primary care centers in southern Thailand, involving 410 participants with at least one chronic condition. Validity assessments included structural, convergent, and discriminant validity. Concurrent validity examined correlations between SC-CII v4.c with the Self-Care Self-Efficacy Scale (SCSES) and self-perceived health. Internal coherence reliability was calculated using Cronbach's α coefficient, item-total correlation coefficients, and the composite reliability (CR) index.

Results

Thai SC-CII v4.c demonstrated excellent translational validity (κ = 0.99). The specified Self-Care Maintenance model fit well, with minor differences in health promoting behavior and illness-related behavior items compared to the original model. The original Self-Care Monitoring, and Self-Care Management models fit well with Thai data. Simultaneous confirmatory factor analysis confirmed a satisfactory fit of the full SC-CII v4.c. Convergent validity had partial support (average variance extracted = 0.23-0.51), and discriminant validity was established (heterotrait-monotrait ratios = 0.37-0.88). Concurrent validity was supported by positive correlations between each scale and overall SC-CII v.4c with SCSES (r = 0.25-0.65) and self-perceived health (r = 0.09-0.35). The Cronbach's α coefficient were adequate for all scales except the Self-Care Maintenance scale (Cronbach's α = 0.68), but the CR estimate improved the reliability of all three scales (ranging 0.80-0.82). All items had satisfactory item-total correlation coefficients (ranging 0.34-0.71), except the one pertaining to sleep.

Conclusions

The Thai SC-CII v4.c is valid and reliable for assessing self-care in various chronic illnesses. Further testing is recommended for patients with specific diseases.

Anxiety and Depressive Symptoms in Patients with COPD: Modifiable Explanatory Factors

Anxiety and depressive symptoms affect up to 80% of people with chronic obstructive pulmonary disease (COPD). To reduce this symptom burden, clinicians should target modifiable explanatory factors while accounting for nonmodifiable explanatory factors of these symptoms. The purpose of this secondary data analysis was to examine which modifiable factors explain anxiety and depressive symptoms in COPD. This secondary data analysis of 1,760 COPD patients used multiple regression to explain anxiety and depressive symptoms from sets of modifiable patient characteristics and demographic controls. Clinically significant symptoms of anxiety or depression presented in 29.6% (n = 526) of participants, and 20.6% (n = 363) had both. Significant modifiable explanatory factors of both disorder symptoms were perceived functional status, functional capacity, psychosocial impact, symptom self-management, and significant symptoms for the other. Somatic symptom burden and dyspnea explained anxiety and depressive symptoms, respectively. Addressing these modifiable factors may reduce anxiety and depressive symptoms in patients with COPD.

Psychometric properties of the self-care of chronic illness inventory in Chinese older adults with multiple chronic conditions

BACKGROUND

Existing self-care measures for the Chinese population are specific to single chronic conditions. No generic self-care measures exist for the Chinese population with multiple chronic conditions.

OBJECTIVES

To test the structural validity, concurrent validity and reliability of the Self-care of Chronic Illness Inventory (SC-CII) in Chinese older adults with multiple chronic conditions.

METHODS

This cross-sectional study was reported following the Strengthening the Reporting of Observational Studies in Epidemiology guideline. A diverse sample of Chinese older adults with multiple chronic conditions (n = 240) was recruited. Structural validity was assessed with confirmatory factor analysis. Concurrent validity was investigated with hypotheses testing of the relationships between perceived stress, resilience and self-care. Reliability was assessed with Cronbach's alpha and McDonald's omega. Finally, a simultaneous confirmatory factor analysis was conducted to test the general model with all items and all three subscales.

RESULTS

Confirmatory factor analysis supported the two-factor structure of the self-care maintenance and self-care management subscales and the one-factor structure of the self-care monitoring subscale. Concurrent validity was supported by the significant negative correlation (r ranged from -0.18 to -0.38, p < .01) with perceived stress and the significant positive correlation (r ranged from 0.31 to 0.47, p < .01) with resilience. Reliability estimates ranged from 0.77 to 0.82 across the three subscales. The simultaneous confirmatory factor analysis did not support the more general model with the combined set of items.

CONCLUSION

The SC-CII is valid and reliable for Chinese older adults with multiple chronic conditions. Future cross-cultural assessment should be conducted to investigate the measurement equivalence of the SC-CII in individuals from Western and Eastern cultural groups.

IMPLICATIONS FOR PRACTICE

With the increasing number of older adults in China who are living with multiple chronic conditions and the call for culturally tailored self-care interventions, this self-care measure can be used in geriatric primary care settings, long-term facilities and homes to improve the understanding and practice of self-care in older Chinese adults.

Psychometric Characteristics of the Self-Care of Chronic Illness Inventory in Older Adults Living in a Middle-Income Country

Chronic illness requires numerous treatments and self-care is essential in the care process. Evaluation of self-care behaviors facilitates the identification of patients' needs and optimizes education and care processes. This study aimed to test the psychometric characteristics (validity, reliability, and measurement error) of the Albanian version of the Self-Care of Chronic Illness Inventory (SC-CII). Patients with multiple chronic conditions and caregivers were recruited in outpatient clinics in Albania. The patients completed the SC-CII, which includes three scales: self-care maintenance, self-care monitoring, and self-care management. Factorial validity was tested for each scale, with confirmatory factor analysis. Reliability was evaluated with the composite coefficient, Cronbach's alpha, and the global reliability index for multidimensional scales. The construct validity was tested using hypothesis testing and known differences between groups. The measurement error was tested to assess responsiveness to changes. The self-care maintenance and self-care monitoring scales showed a unidimensional factorial structure, while the self-care management scale showed a bidimensional structure. Reliability estimates were adequate for all reliability coefficients. Construct validity was supported. The measurement error was adequate. The Albanian version of the SC-CII shows good psychometric properties in the Albanian sample.

Instruments Measuring Self-Care and Self-Management of Chronic Conditions by Community-Dwelling Older Adults: A Scoping Review

Given the high prevalence of chronic conditions and multimorbidity in older adults, there is a need to better conceptualize and measure self-care and self-management to promote a person-centered approach. This scoping review aimed to identify and map instruments measuring self-care and self-management of chronic conditions by older adults. We searched six electronic databases, charted data from the studies and tools and reported the results in accordance with the PRISMA-ScR guidelines. A total of 107 articles (103 studies) containing 40 tools were included in the review. There was substantial variation in the tools in terms of their aims and scope, structure, theoretical foundations, how they were developed, and the settings in which they have been used. The quantity of tools demonstrates the importance of assessing self-care and self-management. Consideration of the purpose, scope, and theoretical foundation should guide decisions about tools suitable for use in research and clinical practice.

Self-care and type 1 diabetes mellitus: systematic review of sex-related differences

INTRODUCTION

Self-care is associated with clinical outcomes of adults with T1DM. Some evidence highlighted significant sex-related differences in self-care behaviors in this population. However, the literature on this topic has not been synthesized before. This study aimed to summarize, critically review, and interpret evidence regarding sex-related differences in adults' self-care behaviors with type 1 diabetes mellitus (T1DM).

EVIDENCE ACQUISITION

A systematic search of articles in the following databases was performed: PubMed, Scopus, Embase, and CINAHL. Articles published from 2009 to 2019 were reviewed. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement and flowchart were used to support the systematic review and study reporting. Two reviewers independently screened and extracted data from the included articles.

EVIDENCE SYNTHESIS

From the 596 identified records, only 15 articles were included because pertinent to this review. Both females and males with T1DM must improve their ability to respond to signs and symptoms when they occur. Females are more likely to perform adequate blood glucose monitoring and adequate diet than males. In contrast, males are more likely to show more adequate levels of physical activity.

CONCLUSIONS

Clinicians should pay greater attention to supporting females with T1DM to enhance their behaviors for maintaining an adequate health status and glycemic control. Likely, greater attention is required to sustain males to monitor changes in their signs and symptoms. Self-care management should be improved in both sexes.

Association Between Self-care and Resilience: A Cross-sectional Study in Heart Failure Patients

BACKGROUND

Self-care (SC) is a cornerstone in heart failure management and is related to patient outcomes. The continuous and complex demands of SC can be experienced as stressful and may require patients to apply resilient behaviors as they manage their conditions. Resilience may be a helpful factor in performing SC.

OBJECTIVE

The aim of this study was to determine the association between resilience and SC in patients with heart failure.

METHODS

A cross-sectional study was performed between January 2020 and January 2021. Participants were asked to complete a questionnaire addressing baseline characteristics, the 2-item Patient Health Questionnaire, the Resilience Evaluation Scale, and the Self-Care of Chronic Illness Inventory, which measures 3 concepts of SC: SC maintenance, SC monitoring, and SC management. Multiple regression analysis was performed to determine whether resilience was associated with SC.

RESULTS

Eighty-six patients were included, and 74 patients completed the questionnaire. In the univariate analysis, an association was found between resilience and SC maintenance, resulting in an increase in SC for patients with higher resilience (β = 0.24; 95% confidence interval, 0.03-0.96). In the multivariate analysis adjusted and corrected for confounders, no significant associations between resilience and all SC scales were found.

CONCLUSION

This study could not demonstrate significant associations between resilience and all SC scales. This study contributes to the body of knowledge on factors that can mediate or moderate SC. Further longitudinal research should be performed to study cause-effect relationships.

Development and validation of two versions of the Nurse-Patient Mutuality in Chronic Illness scale

AIMS

The aim of the study was to develop and psychometrically test the Nurse-Patient Mutuality in Chronic Illness (NPM-CI) scale in two versions, one for nurses and one for patients.

METHOD

A multiphase methodological study was conducted. In the first phase, a qualitative investigation was conducted through interviews and an analysis of the content; inductively, the items of two instruments were generated, one for nurses and one for patients. In the second phase, the content and face validity were assessed through the expert consensus method. In the third phase, exploratory factor analysis (EFA), Cronbach's alpha test, intraclass correlation and Pearson correlation coefficients were conducted to estimate construct, criterion validity and instrument reliability. For each phase, the sample included nurses and patients recruited from a large hospital in Northern Italy. Data collection was conducted between June and September 2021.

RESULTS

Nurse and patient versions of the NPM-CI scale were developed. Two rounds of consensus reduced the items from 39 to 20; content validity index ranged between 0.78 and 1, content validity ratio was 0.94. Face validity indicated clarity and comprehensibility of the items. EFA identified three latent factors for both the scales. Internal consistency was satisfactory, with Cronbach's alphas ranging between .80 and .90. Test-retest stability was suggested, with an intraclass correlation coefficient of .96 (nurse scale) and .97 (patient scale). Predictive validity was established, with a Pearson correlation coefficient of .43 (nurse scale) and 0.55 (patient scale) between the mutuality scales and satisfaction in providing and receiving care.

CONCLUSION

The results suggest that the NPM-CI scales are sufficiently valid and reliable for the clinical practice among chronic illness patients and the nurses caring for them. A more in-depth exploration of this construct in the context of nursing and patient outcomes is warranted.

PATIENT OR PUBLIC CONTRIBUTION

Patients were involved in all study phases.

IMPACT

Mutuality is fundamental in the relationship between nurse and patient, based on trust, equality, reciprocity, and mutual respect. The NPM-CI scale was developed and psychometric estimated through a multiphase study in both nurse and patient versions. The NPM-CI scale measures the factors of 'developing and going beyond', 'being the point of reference' and 'deciding and sharing care'. The NPM-CI scale allows us to measure mutuality in clinical practice and research. Expected outcomes and influencing factors for patients and nurses could be associated.

Validity and reliability of the left ventricular assist device self-care behaviour scale

BACKGROUND

Adequate self-care behaviour is essential for patients with a left ventricular assist device (LVAD) to prevent complications, prolong life, and optimise quality of life. However, there were no valid and reliable measurements available to assess self-care behaviour among patients with LVAD. We have previously developed the 33-item LVAD self-care behaviour scale.

OBJECTIVES

To evaluate psychometric properties of the 33-item LVAD self-care behaviour scale.

METHODS AND RESULTS

Data on 127 patients with a LVAD in Israel, Japan, and the USA were analysed (mean age 51±14.3, 81% male). Exploratory factor analysis extracted three factors, and 13 items were excluded from the scale. Internal consistency assessed by Cronbach's alpha was acceptable for the total scale (α = 0.80) and the three subscales: Factor 1: Monitoring (α = 0.81), Factor 2: Heart failure self-care (α = 0.67), and Factor 3: LVAD self-care (α = 0.63). The 20-item version of the LVAD self-care behaviour scale had sufficient convergent validity with another scale that assessed self-care related to the driveline of LVAD (r = 0.47, p<0.001). Test-retest reliability was adequate (intraclass correlation coefficient = 0.58).

CONCLUSIONS

The 20-item version of the LVAD self-care behaviour scale showed adequate validity and reliability. The scale is ready for use in clinical practice and research. Additional testing might further optimise the scale.

Associations between continuity of care, perceived control and self-care and their impact on health-related quality of life and hospital readmission-A structural equation model

AIM

The aim of this study is to examine whether a conceptual model including the associations between continuity of care, perceived control and self-care could explain variations in health-related quality of life and hospital readmissions in people with chronic cardiac conditions after hospital discharge.

DESIGN

Correlational design based on cross-sectional data from a multicentre survey study.

METHODS

People hospitalized due to angina, atrial fibrillation, heart failure or myocardial infarction were included at four hospitals using consecutive sampling procedures during 2017-2019. Eligible people received questionnaires by regular mail 4-6 weeks after discharge. A tentative conceptual model describing the relationship between continuity of care, self-care, perceived control, health-related quality of life and readmission was developed and evaluated using structural equation modelling.

RESULTS

In total, 542 people (mean age 75 years, 37% females) were included in the analyses. According to the structural equation model, continuity of care predicted self-care, which in turn predicted health-related quality of life and hospital readmission. The association between continuity of care and self-care was partly mediated by perceived control. The model had an excellent model fit: RMSEA = 0.06, 90% CI, 0.05-0.06; CFI = 0.90; TLI = 0.90.

CONCLUSION

Interventions aiming to improve health-related quality of life and reduce hospital readmission rates should focus on enhancing continuity of care, perceived control and self-care.

IMPACT

This study reduces the knowledge gap on how central factors after hospitalization, such as continuity of care, self-care and perceived control, are associated with improved health-related quality of life and hospital readmission in people with cardiac conditions. The results suggest that these factors together predicted the quality of life and readmissions in this sample. This knowledge is relevant to researchers when designing interventions or predicting health-related quality of life and hospital readmission. For clinicians, it emphasizes that enhancing continuity of care, perceived control and self-care positively impacts clinical outcomes.

PATIENT OR PUBLIC CONTRIBUTION

People and healthcare personnel evaluated content validity and were included in selecting items for the short version.

Evaluating the Dimensionality and Reliability of the Thai Self-Care of Hypertension Inventory Version 2.0

PURPOSE

Self-care is essential for hypertensive individuals to promote optimal health and illness treatment. We developed the Thai Self-Care of Hypertension Inventory (SC-HI) version 2.0 from the original US version using a multi-stage approach for cross-cultural adaptation. Scales previously studied outside a US context had different dimensions and factor solutions. Therefore, we examined the Thai SC-HI's factorial validity, construct validity, and internal reliability within a Thai context.

METHODS

We administered a cross-sectional survey with hypertensive patients in 10 primary care settings, and conducted exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) on two sets of separate samples from each of five sites to examine the model's factorial validity and construct validity. We estimated scale reliability with Cronbach's alpha and McDonald's omega coefficients.

RESULTS

Participants were predominantly female, older adults, with mean age 66 years (SD = 11.94; range 36-97 years). The self-care maintenance scale had three factors and demonstrated good fit when the error covariances were respecified. The two-factor self-care management scale had different factorial solutions compared to previous models. The CFA result showed good fit indices for the Thai, original US, and Brazilian models. The self-care confidence scale was unidimensional, with partially supported fit indices that improved after we respecified the error covariances. Reliability coefficients estimated by difference methods were nearly equal: slightly lower than desired for self-care maintenance (.68-.70) and inadequate for self-care management (.62-.65); self-care confidence reliability was adequate (.89-.90).

CONCLUSION

The Thai SC-HI has good psychometric characteristics and reflects the original instrument's theoretical basis.

Patient Self-Care and Caregiver Contribution to Patient Self-Care of Chronic Conditions: What Is Dyadic and What It Is Not

OBJECTIVES

Self-care of chronic conditions involves both patients and their informal caregivers and therefore might be considered as a dyadic phenomenon. Nevertheless, empirical evidence supporting a dyadic construct is unavailable. This study aimed to explore the existence of a dyadic construct in self-care maintenance, monitoring, and management in patients affected by chronic conditions and their informal caregivers.

METHODS

This study used a cross-sectional design. We used the Self-Care of Chronic Illness Inventory and the Caregiver Contribution to Self-Care of Chronic Illness Inventory, which measure patient self-care and informal caregivers' contribution to self-care maintenance, monitoring and management. Exploratory Structural Equation Modeling was performed to verify the existence of dyadic latent constructs in each scale in patients and informal caregivers.

RESULTS

A convenience sample of 493 patients and informal caregivers, with a mean age of 76.47 and 52.76 years, respectively, was studied. In the self-care maintenance scales, 2 correlated factors (r = 0.34, P < .001) were identified, indicating the presence of a dyadic second-order construct. In addition, 2 factors that were not correlated (r = 0.11, P = .064) were identified in the self-care monitoring scales, indicating the absence of a dyadic construct. Finally, we found a 3-factor model in the self-care management scales composed of both patient and caregiver items, indicating a dyadic first-order construct.

CONCLUSIONS

Knowing which care behaviors are dyadic in chronic conditions is important for tailoring interventions to improve self-care. Self-care maintenance and management would benefit from dyadic interventions, while self-care monitoring would not. The results of this study may illuminate future theoretical and scientific developments in dyadic care of chronic illness.

Symptom Recognition as a Mediator in the Self-Care of Chronic Illness

Background

The recognition of a symptom is needed to initiate a decision to engage in a behavior to ameliorate the symptom. Yet, a surprising number of individuals fail to detect symptoms and delay in addressing early warnings of a health problem.

Purpose

The aim of this study was to test the hypothesis that symptom recognition mediates the relationship between monitoring for and management of symptoms of a chronic illness.

Methods

A secondary analysis of existing cross-sectional data. A sample of 1,629 patients diagnosed with one or more chronic conditions was enrolled in the United States (US) (n = 407), Italy (n = 784) and Sweden (n = 438) between March 2015 and May 2019. Data on self-care monitoring, symptom recognition, and self-care management was assessed using the Self-Care of Chronic Illness Inventory. After confirming metric invariance in cultural assessment, we used structural equation modeling to test a mediation model where symptom recognition was conceptualized as the mediator linking self-care monitoring and self-care management with autonomous (e.g., Change your activity level) and consulting behaviors (e.g., Call your healthcare provider for guidance).

Results

Symptom recognition mediated the relation between self-care monitoring and autonomous self-care management behaviors (β = 0.098, β = 0.122, β = 0.081, p < 0.001 for US, Italy, and Sweden, respectively). No mediation effect was found for consulting self-care management behaviors.

Conclusion

Our findings suggests that symptom recognition promotes autonomous self-care behaviors in people with a chronic condition. Self-care monitoring directly affects consulting self-care management behaviors but not through symptom recognition. Further research is needed to fully understand the role of symptom recognition in the self-care process.

Self-Care of Chronic Illness Inventory: An Initial Psychometric Evaluation in People Living With HIV in Italy

ABSTRACT

Self-care is essential to achieve positive clinical outcomes in patients with chronic diseases; however, self-care behaviors of people living with HIV (PLWH) have not been extensively studied due to the lack of validated measurements. We performed preliminary psychometric analyses of the structural validity and internal consistency of the Self-Care of Chronic Illness Inventory among 108 PLWH living in Italy and assessed self-care levels. Our findings largely replicate the instrument's original factor structure and indicated high internal consistency and reliability. Additionally, we found that PLWH performed self-care behaviors at suboptimal levels. Recommendations for clinical care and future investigations are advanced.

Development and testing of an instrument to measure contextual factors influencing self-care decisions among adults with chronic illness

Background

Decisions about how to manage bothersome symptoms of chronic illness are complex and influenced by factors related to the patient, their illness, and their environment. Naturalistic decision-making describes decision-making when conditions are dynamically evolving, and the decision maker may be uncertain because the situation is ambiguous and missing information. Contextual factors, including time stress, the perception of high stakes, and input from others may facilitate or complicate decisions about the self-care of symptoms. There is no valid instrument to measure these contextual factors. The purpose of this study was to develop and test a self-report instrument measuring the contextual factors that influence self-care decisions about symptoms.

Methods

Items were drafted from the literature and refined with patient input. Content validity of the instrument was evaluated using a Delphi survey of expert clinicians and researchers, and cognitive interviews with adults with chronic illness. Psychometric testing included exploratory factor analysis to test dimensionality, item response theory-based approaches for item recalibration, confirmatory factor analysis to generate factor determinacy scores, and evaluation of construct validity.

Results

Ten contextual factors influencing decision-making were identified and multiple items per factor were generated. Items were refined based on cognitive interviews with five adults with chronic illness. After a two round Delphi survey of expert clinicians (n = 12) all items had a content validity index of > 0.78. Five additional adults with chronic illness endorsed the relevance, comprehensiveness, and comprehensibility of the inventory during cognitive interviews. Initial psychometric testing (n = 431) revealed a 6-factor multidimensional structure that was further refined for precision, and high multidimensional reliability (0.864). In construct validity testing, there were modest associations with some scales of the Melbourne Decision Making Questionnaire and the Self-Care of Chronic Illness Inventory.

Conclusion

The Self-Care Decisions Inventory is a 27-item self-report instrument that measures the extent to which contextual factors influence decisions about symptoms of chronic illness. The six scales (external, urgency, uncertainty, cognitive/affective, waiting/cue competition, and concealment) reflect naturalistic decision making, have excellent content validity, and demonstrate high multidimensional reliability. Additional testing of the instrument is needed to evaluate clinical utility.

The influence of social support on self-care is mediated by self-efficacy and depression in chronic illness: key findings from the 'SODALITY' observational study

Objectives: Family is a major source of support for older chronically-ill patients and known to be associated with better self-care. Depression and self-care self-efficacy are associated with healthy behaviors and thus may serve as mechanisms by which family support influences self-care.We explored depression and self-care self-efficacy as mediators of the relationship between perceived family support and self-care.Methods: Five hundred forty-one older adults with multiple chronic illnesses were recruited from outpatients and community settings. Three structural equation models (SEM) were fit on cross-sectional data. We measured perceived family support (subscale of the Multidimensional Scale of Perceived Social Support, scores range 1-7), depression (Patient Health Questionnaire, scores range 0-27), selfcare self-efficacy (Self-Care Self Efficacy Scale, standardized scores range 0-100), and self-care maintenance, monitoring, and management (Self-care of Chronic Illness Inventory, standardized scores range 0-100).Results: Participants (mean age = 76.6±7.3 yrs) were predominantly females (55.6%). In the full sample, depression and self-care self-efficacy mediated the relationship between perceived family support and self-care; in the gender-stratified SEM, men's depression was no longer a significant mediator. Depression and self-care self-efficacy were significant mediators of the relation between perceived family support and self-care.Conclusion: In older chronically-ill patients, interventions addressing perceived family support may facilitate a rapid improvement in self-care self-efficacy and a decrease in depressive symptoms, particularly among women.

Measuring self-care in the general adult population: development and psychometric testing of the Self-Care Inventory

Background

Self-care is important at all stages of life and health status to promote well-being, prevent disease, and improve health outcomes. Currently, there is a need to better conceptualize self-care in the general adult population and provide an instrument to measure self-care in this group. Therefore, the aim of this study was to develop and evaluate the Self-Care Inventory (SCI), a theory-based instrument to measure self-care in the general adult population.

Methods

Based on the Middle Range Theory of Self-Care, the 20-item SCI was developed with three scales: Self-Care Maintenance (8 items), Self-Care Monitoring (6 items), and Self-Care Management (6 items). A cross sectional study with a US-based sample (n = 294) was conducted to test the SCI. Internal validity was assessed with Confirmatory Factor Analysis. Internal consistency reliability was assessed with Cronbach alpha for unidimensional scales or composite reliability and the global reliability index for multidimensional scales. Construct validity was investigated with Pearson correlation to test the relationship between general self-efficacy, positivity, stress, and self-care scores.

Results

The Self-Care Maintenance and Management scales were multidimensional and the Self-Care Monitoring scale was unidimensional. The global reliability index for multidimensional scales was 0.85 (self-care maintenance) and 0.88 (self-care management). Cronbach alpha coefficient of the self-care monitoring scale was 0.88. Test-retest reliability was 0.81 (self-care maintenance), 0.91 (self-care monitoring), and 0.76 (self-care management). The General Self-Efficacy Scale was positively related to all three self-care scale scores: self-care maintenance r = 0.46, p < 0. 001, self-care monitoring r = 0.31, p < 0. 001, and self-care management r = 0.32, p < 0. 001. The positivity score was positively related to self-care maintenance (r = 0.42, p < 0. 001), self-care monitoring (r = 0.29, p < 0. 001), and self-care management (r = 0.34, p < 0. 001) scores. The perceived stress was positively related to the self-care management (r = 0.20, p < 0. 001) score.

Conclusions

The SCI is a theoretically based instrument designed to measure self-care in the general adult population. Preliminary evidence of validity and reliability supports its use in the general adult population.
