The problem with Cronbach's Alpha: comment on Sijtsma and van der Ark (2015)

Cultural adaptation and psychometric evaluation of the Italian version of the active-empathic listening scale among undergraduate nursing students: A three phase validation study

AIM

To translate, culturally adapt and evaluate the psychometric properties of an Italian version of the Active Empathic Listening Scale (AELS-It) for first year students on a Bachelor degree in nursing.

BACKGROUND

Active and empathic listening is characterised by the active and emotional involvement of the listener and is particularly important for nurses to understand and address patients' needs. When nurses demonstrate to patients that they are active and empathic listeners, it leads to deeper engagement and trust, strengthens the nurse-patient relationship and enhances the quality of care. Consequently, it is essential to incorporate active and empathic listening into nursing education, as it equips future nurses to communicate and respond to patients' needs effectively. AELS is a tool that measures active and empathic listening styles. To the best of our knowledge, no study has validated and psychometrically tested AELS among nursing students and no studies have examined the application of the AELS scale within the Italian context.

DESIGN

A three-phase validation study.

METHODS

The tool was first translated and adapted into Italian. A panel of 12 experts in nursing education evaluated the face and content validity. The psychometric properties of the Italian AELS (AELS-It) were assessed in a sample of nursing students. The dimensionality and construct validity of the tool were tested through exploratory and confirmatory factor analyses. Reliability was estimated using both traditional and composite methods.

RESULTS

A total of 207 students were included. The overall content validity index was 0.9. The exploratory factor analysis confirmed a three factor structure. Confirmatory factor analysis showed a second-order factor structure with adequate fit indices. The reliability of the second-order factor analysis for the scale was adequate, with Cronbach's α (0.877) and Composite-ω (0.875).

CONCLUSIONS

The Italian version of AELS-It proved to be a reliable tool to test active empathic listening in Italian nursing students and it could be a useful instrument in nursing education.

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 Evaluation of the Traditional Chinese Version of the Self-Care of Heart Failure Index Version 7.2

BACKGROUND

The Self-Care of Heart Failure Index (SCHFI) is a widely used instrument used to measure self-care in both research and clinical settings. The lack of a psychometric evaluation of the traditional Chinese version of the SCHFI (SCHFI-C) might limit its utilization in non-Mainland Chinese populations such as Hong Kong, Macau, and Taiwan.

OBJECTIVE

This study aimed to evaluate the psychometric properties of the SCHFI-C v.7.2.

METHODS

Participants included 365 adults with heart failure. Breslin's method of translation was used to translate the SCHFI v.7.2 into traditional Chinese. Exploratory factor analysis was conducted to examine the dimensionality structure of each scale. Then, composite reliability was calculated to assess the reliability of 3 scales. Construct validity was examined by hypothesis testing and known-group comparisons.

RESULTS

The results of exploratory factor analysis suggest its multidimensionality of each scale. More specifically, the findings indicated a unique internal structure of the self-care maintenance ("lifestyle-related behaviors" and "consulting behaviors") and self-care management ("self-reliance behaviors" and "help-seeking behaviors") scales. The composite reliability of 3 scales were 0.81, 0.88, and 0.82, respectively, reaching adequate level. As for construct validity, the significant associations between the 3 SCHFI domains and self-care confidence as well as significant group difference among patients of different ages and educational backgrounds supported good construct validity.

CONCLUSIONS

This study provides evidence of the reliability and validity of the SCHFI-C v.7.2. The traditional SCHFI-C v.7.2 can serve as a valid and reliable outcome measure to evaluate the effects of self-care-promoting interventions.

Psychometric Evaluation of the Heart Failure Somatic Perception Scale in a Middle Eastern Heart Failure Population

BACKGROUND

The Heart Failure Somatic Perception Scale (HFSPS) is an 18-item instrument used to assess how bothersome are common signs and symptoms of heart failure (HF). To date, the psychometric properties of the HFSPS have been tested in American, Italian, and Japanese samples.

OBJECTIVE

The aim of this study was to evaluate the validity and reliability of the HFSPS in a population of Lebanese patients living with HF.

METHODS

A rigorous translation and back-translation process was performed. Cultural appropriateness ratings were assessed by an expert panel. Exploratory factor analysis was conducted to confirm construct validity, whereas an independent t test using the Minnesota Living With HF Questionnaire's scores was conducted to confirm convergent validity. Pearson correlation was performed to confirm discriminant validity using the Self-Care in HF Index Management subscale, whereas predictive validity was evaluated using the Control Attitudes Scale-Revised. Internal consistency reliability was evaluated using Cronbach α.

RESULTS

A total of 109 patients (mean age, 63.66 ± 10.55 years; 69.7% male) were included. A series of exploratory factor analyses was conducted and resulted in a 4-factor model. Cronbach α was 0.869. Convergent (high correlation with total Minnesota Living With HF Questionnaire; r = 0.762, P < .0001), discriminant (no correlation with self-care management; r = 0.180, P = .078), and predictive (significant correlation with the Control Attitudes Scale-Revised; r = -0.523, P < .0001) validity was supported.

CONCLUSION

The reliability and validity of the HFSPS were supportive in this Middle Eastern sample. The HFSPS can be used to assess how bothersome HF symptoms are to improve their management.

The Effects of Childhood Adversity and Self-Regulation on the Well-Being of Adults with Delinquency Histories: A Mediation Model

PURPOSE

Most youth with delinquency histories experience childhood adversity leaving them vulnerable to poor adult well-being. Previous research indicates that self-regulation difficulties could explain how childhood adversity affects adult well-being. Yet, very few studies target adult self-regulation intervention. Therefore, this study examined the intervening effects of emerging adult self-regulation on the association between childhood adversity and adult well-being.

METHOD

Using data from the first four waves of the Add Health Study, the researchers conducted structural equation modeling for mediation with bootstrapping. The researchers tested the mediation effects of emerging adult self-regulation on the association between childhood adversity (child maltreatment and violent victimization) and later adult well-being (mental health problems, alcohol and drug use, criminal behaviors) among people with delinquency histories and/or arrest prior to age 18 (N = 1,792).

RESULTS

Several significant direct effects and one partial mediation effect were found. For example, child maltreatment significantly predicted adult mental health problems and criminal behaviors. Self-regulation (via the dissatisfaction with life and self subscale) mediated the association between child maltreatment and adult mental health problems.

DISCUSSION

Findings highlight the need for social workers to focus on prevention services and trauma-informed treatment for people with delinquency histories. In addition, evidence-based practice requires self-regulation interventions for adults with histories of childhood adversity and delinquency to focus on their emotional and cognitive functioning as well as self-esteem.

CONCLUSION

Implementing self-regulation interventions during emerging adulthood can be useful to mitigate later adult mental health problems among people with histories of childhood adversity and delinquency.

Reliability and Validity of the Chinese Version of Advance Care Planning Self-efficacy Scale for Physicians

Background: Chinese patients prefer physicians to initiate advance care planning (ACP) conversations, but there is no appropriate tool to evaluate physicians' ACP self-efficacy level in mainland China. This study aimed to translate the ACP self-efficacy scale into Chinese (ACP-SEc) and measure its psychometric properties among clinical physicians. Method: The original scale was translated by literal translation, synthesis, and reverse translation, according to Brislin's translation model. Seven experts were invited to further revise the scale and evaluate the content validity. 348 physicians were conveniently sampled to evaluate the reliability and validity of the scale from May to June 2021 in 7 tertiary hospitals. Results: The ACP-SEc contained 17 items, 1 dimension, with a total score of 17 to 85 points. In this study, the critical ratios of the items ranged from 12.533 to 23.306, the item-total correlation coefficients ranged from 0.619 to 0.839. The item-content validity index ranged from 0.86 to 1.00, and the average scale-level content validity index was 0.98. In total, 75.507% of the total variance was explained by 1 common factor. The results of confirmatory factor analysis showed that the fitting indices of the modified model were desirable. The ACP-SEc was moderately correlated with General Self-Efficacy Scale (r = 0.675, P < .001), and it differentiated between physician groups based on the knowledge level of ACP, palliative care or ACP-related training experience, attitude toward ACP, willingness to initiate ACP discussions with patients, and experience of discussing ACP with family and friends, willingness to initiate ACP discussions with family and friends (P <.05). The total Cronbach's α and test-retest reliability of the scale were .960 and .976, respectively. Conclusion: The ACP-SEc shows good reliability and validity, and it can be used to assess the ACP self-efficacy level of physicians.

Spanish version of the Heart Failure Somatic Perception Scale (HFSPS v.3) - psychometric properties

Background

The Heart Failure Somatic Perception Scale (HFSPS) is an instrument that examine the existence and gravity of physical signs and symptoms in patients with heart failure, as well as early and subtle symptoms of HF that have clinical value, we aimed to translate and adapt the HFSPS from English to Spanish and evaluate the psychometric properties.

Method

HFSPS translation and back translation were carried out according to the method established by of Beaton et al. A confirmatory factor analysis (CFA) was performed to test the factor structures. To assess criterion-related validity, HFSPS factor scores were correlated with Kansas City Cardiomyopathy Questionnaire (KCCQ) scores using the Spearman correlation method. The reliability of the internal consistency of the HFSPS was determined by calculating the Cronbach's alpha coefficient and the factor score determination coefficient.

Results

Data from 173 patients with a mean age of 80.7 years (SD 9.1), women (51.1%), were analyzed. The majority (74.7%) were NYHA class II/III. The confirmatory factor analysis of four factors after eliminating one item showed fit indices close to the recommended indices: χ2 = 169.237, p < 0.001, CFI = 0.920, TLI = 0.901, RMSEA = 0.057 and SRMR = 0.061. Regarding the validity related to the criterion, all the scores of the HFSPS dimensions were correlated with all the scores of the KCCQ dimensions and were statistically significant. The reliability of the HFSPS factors of the coefficient of determination obtained scores of 0.73 for the dyspnea factor and early and subtle and lower for edema and chest discomfort with fewer items. Cronbach's alpha was acceptable for three of the scales >0.71 and poor 0.52 for chest discomfort with two items. The internal consistency index based on the model was 0.850.

Conclusion

The Spanish version of the HFSPS is a valid and reliable instrument that that would be feasible to use in clinical and research setting to evaluate in the perception of symptoms in patients with heart failure.

Development and validation of a Sarcopenia Geriatric Scale (SARCO-GS): a new short scale for the screening of sarcopenia

Introduction

Sarcopenia is a highly prevalent disease associated with adverse outcomes such as falls, disability, and death. The current international consensuses agree that muscle strength, muscle mass, and gait speed must be included in the definition. However, these proposed criteria require objective measurements that are not available for most populations. Since the timely identification of sarcopenia is a priority, several subjective screening scales have been developed; however, they have some limitations due to their low sensitivity. The objective of this work was to develop and validate SARCO-GS, a new short scale to screen sarcopenia that is affordable, easy, and accessible for all clinical care settings.

Methods and materials

The development of the SARCO-GS included four stages: (1) Review and analysis of documentary sources, (2) Contextualization of the theoretical model of sarcopenia, (3) Scale conformation, and (4) Reliability and validity analyses. SARCO-GS was validated in the FraDySMex study, which is a longitudinal cohort of community-dwelling adults.

Results

In the studied population (n=852), the average age was 68.9 years (SD 10.21) and 80.1% of the participants were women. SARCO-GS is a seven-item scale with an innovative structure that included five subjective questions (gait speed, muscular strength, muscle mass) and two measurements of muscular strength and muscle mass (Chair stand test and calf circumference). The results regarding criterion validity showed that the cut-off point ≥ 3 had good sensitivity (77.68%) versus the EWGSOP2 consensus, with an adequate Area Under the Receiver Operating Characteristic (AUC) (0.73), in addition to showing higher values of sensitivity and AUC than SARC-F and SARC-CalF using as reference the same consensus. Furthermore, SARCO-GS presented good predictive validity for functional dependence (HR=2.22, p=0.046) and acceptable correlation with other related measurements (construct validity). Regarding reliability, the scale showed acceptable internal reliability (correlation between items and total score: 0.50 to 0.70). After the validation analysis, the scale was adapted to English.

Conclusions

The SARCO-GS is a novel scale to screen sarcopenia with high sensitivity, good construct, predictive validity, and internal reliability that may be useful for health professionals in different clinical settings and for clinical research.

A Comparison of Checklist and Domain-Based Ratings in the Assessment of Objective Structured Clinical Examination (OSCE) Performance

INTRODUCTION

The Objective Structured Clinical Examination (OSCE) is the mainstay of clinical assessment in the final-year undergraduate Family Medicine clerkship at King Faisal Specialist Hospital and Research Centre (KFSHRC). The gold standard for OSCE assessment is the checklist rating, completed by physician examiners. Numerous studies have suggested that global or domain-based OSCE ratings may be a better indicator of competence than checklist ratings. The aim of this study was to examine the utility of domain-based OSCE ratings in the context of final-year, undergraduate, Family Medicine OSCE examinations in Riyadh, Saudi Arabia. This is akin to an exercise in quality improvement, as we continuously look for ways to improve our OSCE assessment processes.

METHODS

This study utilised a quantitative methodology. Three final year OSCE exams were chosen. Physicians rated each student using a checklist score and using a more holistic domain-based score. Physician checklist scores and physician domain-based scores were then compared, and correlation was assessed. We also looked at the internal consistency of the scoring methods.

RESULTS

A significant correlation was found between checklist and domain-based scores by physicians for all exams (r=0.858, p<0.01), with a good internal consistency for these methodologies for all exams.

CONCLUSION

The results demonstrate that both checklist and domain-based scores offer some benefit to the assessment, with a similar internal consistency and strong correlation. Domain-based ratings should be utilised for softer skills that are not easily assessed by checklists. There is clearly a need to rethink our OSCE assessment. The assessment should combine checklist and domain-based physician scores. As trainees become more experienced, checklist OSCE may penalise directness and efficiency, while domain-based ratings would offer a better appraisal of competence, and have been shown to be more sensitive to the level of training and expertise. Changing the assessment methods will lead to necessary changes in the student approach to the OSCE and improve authenticity and validity.

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.

The Chinese version of informant AD8 for mild cognitive impairment and dementia screening in community-dwelling older adults

BACKGROUND

Conducting routine mild cognitive impairment (MCI) and dementia screening for older adults in the community is important, which not only can improve our understanding of these diseases but also can increase early detection and treatment.

METHODS

To analyze the reliability and validity of the informant AD8 and explore the cut-off values for screening MCI and dementia in the community-dwelling older adults, this study adopted a multi-stage cluster sampling method to recruit 327 participants aged 60 and over in communities. The informant AD8 and Clinical Dementia Rating (CDR) scales were used to evaluate cognitive function of the subjects, and the receiver operating characteristic curves (ROC) was conducted to test the screening efficacy.

RESULTS

Among the 327 participants, 33.0% of them met the criteria of MCI, and 3.4% of them met the criteria of dementia. The area under the receiver operating characteristic curve (AUC) of the informant AD8 for screening dementia was 0.974, with a screening cut-off of three, sensitivity of 90.9% and specificity of 89.0%. But it has a poor discriminability in MCI screening [AUC = 0.645, 95% confidence interval (CI): 0.578-0.711].

CONCLUSIONS

This study suggests that the informant AD8 is an ideal and useful tool for dementia screening in community-dwelling older adults. However, it is less capable to distinguish older adults with MCI from those with normal cognitive function.

The 22-Item Benefit Finding Scale: Validation and Application among Patients with Cervical Cancer in Ethnic Minority Areas of Southwestern China

Recently, the Benefit Finding Scale (BFS) has been translated and culturally adapted for use in China. However, further validation of the instrument is required before it can be used in the management of patients with cervical cancer in China. In this study, we conducted the questionnaire survey and examined its properties. This methodological study was conducted at a tumor hospital located in southwestern China. Patients with cervical cancer who had been reexamined in the outpatient department of the hospital and hospitalized from June to August 2019 were selected. The item analysis, exploratory factor analysis (EFA), and reliability analysis were tested. The relationships between benefit finding and sociodemographic and disease-related variables were analyzed by ANOVA and regression models. A total of 247 patients were assessed (mean age: 48.0 ± 13.3 years). Educational level, self-perceived disease severity, and physical exercise were the predictors of benefit finding. The correlation coefficient between 22 items and their dimensions was the best. EFA analysis supported a five-factor model for structure validity. All Cronbach's alpha for the Chinese version of the BFS (BFS-C) was greater than 0.80. The results demonstrated the good reliability and validity of BFS-C. It appears to be a useful scale to assess experience of benefit finding among patients with cervical cancer in China.

Validity and Reliability of the Korean Version of the Revised Self-Care of Heart Failure Index v7.2

The psychometric properties of the Korean version of the revised Self-Care of Heart Failure Index (SCHFI) remain undetermined; therefore, we aimed to evaluate the construct and convergent validity and reliability of the Korean version of the SCHFI in Korean patients with heart failure (HF). Using a cross-sectional design, 207 patients with HF provided data on self-care and self-efficacy in self-care for this psychometric testing. The confirmatory factor analysis supported the construct validity of the Korean version with a three-factor structure: Self-Care Maintenance, Symptom Perception, and Self-Care Management. Convergent validity was supported by the significant relationships between self-efficacy and each scale of the Korean version of the SCHFI (r = .425-.549, p < .001). The reliability estimates were marginally adequate, with a Cronbach's alpha of .655 to .776, McDonald's omega of .710 to .836, and composite reliability coefficients of .704 to .834. The SCHFI was supported as a valid and reliable measure of self-care for Koreans with HF. However, the marginal levels of the Cronbach's alpha coefficients still require validation in a larger sample.

Validity and reliability of the Patient Health Questionnaire scale (PHQ-9) among university students of Bangladesh

This study investigated the reliability and factorial validity of Patient Health Questionnaire-9 (PHQ-9) in the context of university students in Bangladesh. The research aimed to assess whether the original one-dimensional model or a model containing both somatic and cognitive-emotional factors is appropriate in the case of a sample of university students. A repeated cross-sectional survey design based on convenience sampling was used to collect data from 677 university students from both public and private universities. The factor structure of the PHQ-9 was assessed using confirmatory factor analysis (CFA). Measurement invariances were assessed across gender, type of university, level of education and victim of domestic violence. Its convergent validity was determined by investigating its correlations with Generalized Anxiety Disorder-7 (GAD-7) and Patient Health Questionnaire Anxiety-Depression Scale (PHQ-ADS). Results showed excellent reliability of PHQ-9 as measured by both Cronbach's α and McDonald's ω. CFA suggested that a modified one-factor model where the error variances between item-3 ('sleeping difficulties') and item-6 ('feeling as a failure'), item-6 and item-9 ('suicidal thoughts'), item-4 ('feeling tired') and item-9, item-3 and item-9 were allowed to covary is appropriate for the sample. This model provided high values of comparative fit index (CFI), goodness of fit index (GFI), and Tucker Lewis Index (TLI), low value of standardized root mean square residual (SRMR) and a non-significant root mean square error of approximation (RMSEA) as well as a high Factor Determinacy Score Coefficient. Correlation between PHQ-9 and GAD-7 was 0.751 and 0.934 between PHQ-9 and PHQ-ADS. Finally, the model is strictly invariant across gender and university type. Overall, the study provided support for modified unidimensional structure for PHQ-9 and showed high internal consistency along with good convergent validity.

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.

Predictors of Self-care Among Chinese Patients With Chronic Heart Failure

BACKGROUND

Self-care is important for improving the health outcomes of individuals with chronic heart failure (CHF). However, predictors of self-care behaviors remain unclear in Chinese society.

OBJECTIVE

The aims of this study were to explore predictors of self-care in Chinese patients with CHF and clarify the complex relationships between predictors and self-care behaviors guided by the Situation-Specific Theory of Heart Failure Self-Care.

METHODS

A cross-sectional study was conducted among individuals hospitalized with CHF in China. Person, problem, and environmental factors pertaining to self-care were collected by a questionnaire survey. Self-care was assessed by the Self-Care of Heart Failure Index version 6. Direct and indirect relationships between factors and self-care behaviors and the mediating role of self-care confidence were analyzed by the structural equation model.

RESULTS

In total, 204 participants were involved in this study. The Situation-Specific Theory of Heart Failure Self-Care model demonstrated a good fit (root mean square error of approximation, 0.046; goodness of fit index, 0.966; normed fit index, 0.914; comparative fit index, 0.971). Inadequate self-care capabilities were common among Chinese patients with CHF. Person-related factors (female gender, higher monthly income and educational level), problem-related factors (severe New York Heart Association function class and better instrumental activities of daily living), and environmental factors (better social support and living in more developed areas) were significant predictors of better self-care behaviors ( P < .05). These associations were partly or fully mediated by self-care confidence.

CONCLUSION

The Situation-Specific Theory of Heart Failure Self-Care can be used to guide research and practice in patients with CHF. Interventions and policies on promoting self-care in Chinese population living with CHF are encouraged, particularly for underserved populations.

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.

Nurses' Quality of Life Scale: validation and psychometric properties

The Nursing Quality of Life Scale (NQOLS) is a 28-item self-report measure evaluating the four dimensions of nurses' quality of life, namely, the physical, emotional, working, and social dimensions. The purpose of this study is to assess the psychometric properties, including validity and reliability, of the NQOLS. The study enrolled 1,105 nurses who provided direct assistance to patients. The NQOLS factorial structure was tested using a cross-validation approach via Exploratory Structural Equational Modeling, which confirmed the instrument's four-dimension structure. Reliability was assessed using omega coefficients, proving excellent for all factors. Cluster analysis identified five distinct groups, each composed of participants sharing a substantial similarity with respect to their profile in the NQOLS. These five identifiable clusters presented significant differences not only in the NQOLS but also in the risk of work-related stress, emotional labour and burnout. The results show that NQOLS is a simple, reliable, lean tool for measuring nurses' overall QoL, whose various parts can additionally be used to answer specific research questions.

Moral distress in nursing students: Cultural adaptation and validation study

BACKGROUND

Moral distress, defined as moral suffering or a psychological imbalance, can affect nursing students. However, many new instruments or adaptations of other scales that are typically used to measure moral distress have not been used for nursing students.

AIM

This study aimed to translate, culturally adapt and evaluate the psychometric properties of an Italian version of the Moral Distress Scale for Nursing Students (It-ESMEE) for use with delayed nursing students (students who could not graduate on time or failed the exams necessary to progress to the next level).

RESEARCH DESIGN

The study used a cross-sectional research design.

PARTICIPANTS AND RESEARCH CONTEXT

Incidental sampling resulted in a sample of 282 delayed nursing students (mean age = 26.73 ± 4.43 years, 73% female) enrolled between May and August 2020 in a University of central Italy.

ETHICAL CONSIDERATIONS

The research protocol was approved by the internal review board of the university, and all participants provided their written informed consent.

RESULTS

The study confirmed a multidimensional second-order factorial structure for the It-ESMEE with five dimensions: improper institutional conditions to teach user care, authoritarian teaching practices, disrespect for the ethical dimension of vocational training, lack of competence of the teacher and commitment of ethical dimension of user care. The internal consistency was high (0.753-0.990 across the factors), and the standard error of measurement and smallest detectable change were adequate.

DISCUSSION

The It-ESMEE is able to assess moral distress in delayed nursing students with good validity and reliability. It can be used in research and to determine moral distress levels, helping teachers to monitor the condition in nursing students.

CONCLUSION

This instrument can help in comprehending moral distress, enabling students to develop coping and intervention strategies to maintain their well-being, and to ensure the quality of nurse education.

Psychometric Characteristics of the Caregiver Contribution to Self-care of Heart Failure Index in a South American Population

BACKGROUND

Caregivers can contribute enormously to the self-care of patients with heart failure (HF). The Caregiver Contribution to Self-care of Heart Failure Index (CC-SCHFI) measures these contributions across 3 scales: self-care maintenance, which evaluates caregiver contributions to symptom monitoring and treatment adherence; self-care management, which evaluates caregiver contributions in dealing with symptoms; and caregiver confidence, which assesses caregiver self-efficacy in managing all contributions to self-care. Although the CC-SCHFI has been used in several investigations, only 1 study has evaluated its psychometric characteristics.

OBJECTIVE

The aim of this study was to evaluate the psychometric properties of the CC-SCHFI in Brazil.

METHODS

A cross-sectional design was used in this study. Confirmatory factor analysis was used to assess construct validity, and factor score determinacy coefficients were computed to evaluate internal consistency reliability.

RESULTS

The sample comprised 99 caregivers of patients with HF. Most were women (73%), with a mean age of 48 ± 14 years; 57% were patients' spouses. Confirmatory factor analysis confirmed the original factor structure of the instrument, with supportive fit indices for all 3 scales (comparative fit index, 0.95-1.00; root-mean-square error of approximation, 0.00-0.057). Reliability estimates were adequate for each CC-SCHFI scale (0.77-0.96).

CONCLUSIONS

The CC-SCHFI is a valid and reliable scale to measure caregiver contributions to self-care maintenance, caregiver contributions to self-care management, and caregiver confidence in HF.

Development and Psychometric Testing of the Caregiver Self-Efficacy in Contributing to Patient Self-Care Scale

OBJECTIVES

Caregiver self-efficacy-a caregiver's belief in his/her ability to contribute to patient self-care-is associated with better patient and caregiver outcomes in single chronic conditions. It is, however, unknown if caregiver self-efficacy improves patient and caregiver outcomes in multiple chronic conditions (MCCs) because there is no instrument to measure this variable. We developed the 10-item Caregiver Self-Efficacy in Contributing to patient Self-Care (CSE-CSC) scale for that purpose, and we tested its psychometric characteristics in caregivers of patients with MCCs.

METHODS

In this cross-sectional multisite study, we tested the structural validity of the CSE-CSC scale with exploratory and confirmatory factor analysis, and we tested construct validity by correlating CSE-CSC scores with those of the Caregiver Contributions to Self-Care of Chronic Illness Inventory. We also tested reliability, and precision of the CSE-CSC scale.

RESULTS

The 358 enrolled caregivers (mean age 54.6 years; 71.5% female) cared for patients with an average of 3.2 chronic conditions. Structural validity was good, and it showed 2 factors within the scale. Construct validity showed significant correlations between scores of the CSE-CSC scale and the Caregiver Contributions to Self-Care of Chronic Illness Inventory. Reliability coefficients were between 0.90 and 0.97. Measurement error yielded satisfactory results.

CONCLUSIONS

The CSE-CSC scale is valid, reliable, and precise in measuring caregiver self-efficacy in contributing to patient self-care in MCCs. Because caregiver self-efficacy is a modifiable variable, the CSE-CSC scale can be used in clinical practice and research to improve patient and caregiver outcomes.

Further Evidence of Psychometric Performance of the Self-care of Diabetes Inventory in Adults With Type 1 and Type 2 Diabetes

BACKGROUND

The Self-care of Diabetes Inventory (SCODI) is a theory-based tool that measures self-care, a key strategy in the appropriate treatment of diabetes. However, despite the clinical differences between people with Type 1 Diabetes Mellitus (T1DM) and Type 2 Diabetes Mellitus (T2DM), the psychometric properties of the SCODI were only tested in mixed samples.

PURPOSE

This study aims to test the psychometric performances of the SCODI in two separate groups of adults with T1DM and T2DM.

METHODS

This is a secondary analysis from two previous multicentre cross-sectional observational studies involving patients with T1DM (n = 181) and T2DM (n = 540). We tested dimensionality with confirmatory factor analysis and reliability with a multidimensional model-based coefficient for every scale of the SCODI: self-care maintenance, self-care monitoring, self-care management, and self-care self-efficacy.

RESULTS

We found that the SCODI showed the same dimensionality, with minimal variation in factor loadings for each factor and each scale among T1DM and T2DM groups. High reliability for each scale in both groups was also found (self-care maintenance: T1DM = 0.86, T2DM = 0.83; self-care monitoring: T1DM = 0.84, T2DM = 1.00; self-care management: T1DM = 0.87, T2DM = 0.86; self-care self-efficacy: T1DM = 0.88; T2DM = 0.86).

CONCLUSION

The SCODI can be used for measuring self-care in people with T1DM, T2DM, or mixed groups using identical scoring procedures. Considering the well-known differences between Type 1 and Type 2 diabetes diseases and patients' characteristics, our results support the generalizability of the self-care theory on which the instrument is based.

Validity and Reliability of the Caregiver Contribution to Self-Care of Heart Failure Index Version 2

BACKGROUND

Lay caregivers are important in contributing to self-care of patients with heart failure (HF). The Caregiver Contributions to Self-Care of Heart Failure Index (CC-SCHFI) measures these contributions, but after developing the Situation-Specific Theory of Caregiver Contributions to Heart Failure Self-Care, the CC-SCHFI needed updating to reflect the theory.

OBJECTIVE

The aim of this study was to test the psychometric characteristics of the CC-SCHFI 2 that measures caregiver contributions (CC) to HF self-care with 3 scales: CC to self-care maintenance, CC to symptom perception, and CC to self-care management.

METHODS

This is a cross-sectional study. We tested the CC-SCHFI 2 with confirmatory factor analysis, internal consistency, item-total correlations, and test-retest reliability. With the CC-SCHFI 2, we also administered the Self-Care of Heart Failure Index v.7.2 to patients and the Caregiver Contribution to Heart Failure Self-Care Scale to caregivers to assess concurrent validity.

RESULTS

A sample of 277 caregivers was enrolled (mean [SD] age, 52.7 [14.9] years; 70.4% female). In confirmatory factor analysis, each CC-SCHFI 2 scale had supportive fit indices: comparative fit index ranged between 0.94 and 0.95, and root mean square error of approximation ranged between 0.05 and 0.07. Internal consistency of the 3 scales was evident with a Cronbach α between .81 and .83 and a global reliability index between 0.79 and 0.86. Item-total correlations were all greater than 0.30. In concurrent validity testing, there were significant correlations between the CC-SCHFI 2 and the Self-Care of Heart Failure Index v.7.2 and the Caregiver Contribution to Heart Failure Self-Care Scale. Test-retest reliability showed intraclass correlation coefficients between 0.72 and 0.91.

CONCLUSIONS

Testing of the CC-SCHFI 2 supported validity and reliability, indicating that the instrument can be used in clinical practice and research to evaluate CC to the self-care of patients with HF.

Self-care in spinal cord injuries inventory (SC-SCII) and self-care self-efficacy scale in spinal cord injuries (SCSES-SCI): development and psychometric properties

STUDY DESIGN

Validation cross-sectional study.

OBJECTIVES

To develop and assess the psychometric properties of two instruments based on the middle-range theory of self-care in chronic illness: the Self-Care in Spinal Cord Injuries Inventory (SC-SCII) and the Self-Care Self-Efficacy Scale in Spinal Cord Injuries (SCSES-SCI).

SETTING

Multicenter study in five spinal units across Italy and Ireland.

METHODS

Instrument development was based on self-care behaviours identified in the scientific literature. Behaviours were grouped into four dimensions during a consensus conference: self-care maintenance, self-care monitoring, self-care management and self-care self-efficacy. Sixty-seven items were subsequently generated based on these dimensions. A multidisciplinary group of 40 experts evaluated content validity. Dimensionality of the final items was tested by confirmatory factor analyses (CFA) with a sample of 318 participants. Internal consistency and test-retest reliability were evaluated for each dimension. Construct validity was assessed using correlations between items and scoring differences amongst participants with more severe conditions and secondary complications.

RESULTS

Content validity of the SC-SCII and SCSES-SCI was satisfactory for thirty-five of the previously generated items, which were further refined. CFA showed comparative fit indexes ranging from 0.94 to 0.97 and root mean square errors of approximation from 0.03 to 0.07. Internal consistency ranged from 0.71 to 0.85, and intraclass correlation coefficients were higher than 0.70. Correlations among dimensions were moderate, and the theoretical hypotheses formulated when designing the instruments were largely confirmed.

CONCLUSIONS

The SC-SCII and the SCSES-SCI represent valid and reliable theoretically-grounded instruments to assess self-care in people with spinal cord injury.

Development and psychometric testing of the European Heart Failure Self-Care behaviour scale caregiver version (EHFScB-C)

BACKGROUND

The European Heart Failure Self-Care Behaviour Scale (EHFScBS) is used worldwide to measure heart failure (HF) patient self-care, but a caregiver version does not exist.

OBJECTIVE

To develop and test the European HF Self-Care Behaviour Scale for Caregivers (EHFScBS-C) in a population of informal caregivers of HF patients.

METHODS

The EHFScBS-C was derived from the EHFScBS to measure the extent to which caregivers contribute to HF patient self-care. The EHFScBS-C was developed in English and then translated into Italian, Spanish and Dutch, after which it was back-translated. EHFScBS-C data were collected from 193 HF caregivers enrolled in Italy, Spain and the Netherlands.

RESULTS

Exploratory factor analysis revealed two factors with supportive fit indices (CFI = 0.990; RMSEA = 0.048): caregivers' contributions to HF self-care related to medical issues, and caregivers' contributions related to lifestyle. Internal consistency reliability was supported as well (Cronbach's alpha 0.90 for the overall scale). Construct validity was demonstrated with significant correlations with the Caregiver Preparedness Scale.

CONCLUSION AND PRACTICE IMPLICATIONS

The EHFScBS-C has adequate validity and reliability for its use in clinical practice and research to measure the extent to which caregivers contribute to HF patient self-care. The EHFScBS-C can be used in combination with the EHFScBS to conduct dyadic studies.

The Role of Social Support in Identity Processes and Posttraumatic Growth: A Study of Victims of Intimate Partner Violence

The purpose of this study was to explore the role of social support for posttraumatic growth (PTG) and identity processes in a sample of 217 women victims of intimate partner violence (IPV), recruited from women shelters, social support centers, and through counseling psychologists. The results of the study highlight the important role of social support in seeking positive personal resolutions after experiencing traumatic events of IPV. It indicates that social support, but not social nonsupport, predicts higher levels of PTG and the development of new positive identities. In particular, social support was positively associated with the manifestation of all five identity processes, that is, with identification with commitment, commitment making, exploration in breadth, exploration in depth, and ruminative exploration. Furthermore, contextual and socioeconomic factors, such as time after last violence, relationships with the perpetrator, place of residence, education, and age of the victims of IPV were also related to identity processes. Severity of the violence, time after the last violence, education, and personal income were related to PTG. Thus, this study indicated that there are significant contextual and socioeconomic differences in the PTG and reconsideration of one's identity. Recommendations for practitioners and future research have been suggested.

Development and psychometric testing of the care dependence perception questionnaire

OBJECTIVE

This multicentre study aimed to develop a measure of the perception of care dependence in patients diagnosed with cancer and to test its psychometric properties.

METHODS

The questionnaire was developed based on findings emerged from a meta-synthesis and from qualitative studies conducted in three hospitals in Italy. The draft questionnaire was tested for face and content validity and pilot-tested with patients. The questionnaire was completed by care-dependent patients with cancer. Test-retest was conducted to verify stability. Exploratory factor analysis (EFA) was performed using a Maximum Likelihood robust estimator.

RESULTS AND CONCLUSION

The Scale-Content Validity Index was 0.92. The final 15-item questionnaire was completed by 208 patients admitted to two hospitals. The EFA yielded a two-factor model including a positive and a negative perception of care dependence. Factor score determinacy coefficients, Cronbach's alpha coefficients, composite reliability coefficients and Intraclass Correlations Coefficients yielded satisfactory results confirming internal consistency and stability. The hedonic balance score is also available as a single indicator of subjective well-being. The study provides initial validation of the Care DEeP Questionnaire that can be used by cancer nurses to assess positive and negative patient experiences with care dependence and to personalise and improve their care.

The Cross-Cultural Adaptation and the Reliability Test for the Chinese-Version Dietary Behavior and Psychological Series Scales in Maintenance Hemodialysis Patients

PURPOSE

To translate three novel measures of psychological mechanisms associated with dietary behavior, including the Dietary Goal-Desire Incongruence scale (DG-DI), the Motivation for Dietary Self-control scale (MDSC), the Satisfaction with Dietary Behavior scale (SWDB), to cross-culturally adapt the measures into Chinese and verify their reliability and validity in maintenance hemodialysis patients.

METHOD

After the forward translation and the back-translation, the perspective of a panel of experts and cognitive interviews with maintenance hemodialysis patients were used to ensure cultural relevance of the three scales. Subsequently, 420 maintenance hemodialysis patients from three hemodialysis centers in Zhengzhou were recruited for the item analysis and the internal consistency, content validity, construct validity and reliability tests.

RESULTS

The moderate associations between items and domains (r>0.50) and the significant differences between the high and low groups were measured by an independent sample t test (P<0.001). The Cronbach's α coefficient of the DG-DI reached 0.884. The Cronbach's α of the MDSC was 0.831, with Cronbach's α values (0.865,0.800 and 0.797 for "Internal", "External" and "Amotivation", respectively). In addition, the Cronbach's alpha of the SWDB was 0. 914. The scale-level content validity index (S-CVI) reached 0.96, 0.98 and 1.00 for the DG-DI, the MDSC and the SWDB, respectively. The exploratory factor analysis verified the scale structures of five factors, and the cumulative variance contribution rate of the respective factor was 65.507%. The confirmatory factor analysis was conducted to test the original structure of the scale.

CONCLUSION

The DG-DI, the MDSC and the SWDB showed satisfactory psychometric characteristics. They could effectively assess the eating behavior of hemodialysis patients. Subsequent studies should recruit other different population samples in China to verify the applicability of the scale.

Cross-cultural adaptation and validation of the First-Time Fathers Questionnaire in China

OBJECTIVE

The study aimed to cross-culturally adapt and validate the First-Time Fathers Questionnaire (FTFQ) in the cultural context of China.

DESIGN

Prospective validation study.

SETTING

The study was conducted in four public hospitals in Hangzhou, a southeast coastal city of China.

PARTICIPANTS

Four hundred and nineteen first-time fathers (mean age=30.45 years, SD=3.44, range 22-46) whose partners had given birth between July 20 and October 10, 2019.

METHODS

The instrument "First Time Fathers Questionnaire (FTFQ)" was translated and culturally adapted to the Chinese context according to the methodological criteria of the International Society for Pharmacoeconomic and Outcomes Research. The construct-related validity of the instrument was tested through EFA and CFA. Content validity was evaluated with an analysis of the expert judgment. Reliability was assessed based on the internal consistency.

RESULTS

Four domains were identified: "Worry", "Information", "Emotional Support", and "Acceptance", with 19 items and adequate internal reliability (0.86, 0.80, 0.86, and 0.72, respectively) and a total variance of 64.65%. The CFA model showed there is a good fit for the data: X²/df =1.20; RMSA = 0.03; CFI = 0.99; and NFI = 0.93. Additionally, each item achieved an I-CVI ≧0.83, and the S-CVI/Ave = 0.90.

KEY CONCLUSIONS

The Chinese version of the FTFQ is a valid and reliable instrument to assess first-time fathers' experience of childbirth in China.

IMPLICATIONS FOR PRACTICE

This study provides a validated questionnaire that is suitable for the Chinese cultural context. It contributes to the knowledge of first-time fathers' experience of childbirth and facilitate further actions to improve paternal satisfaction and behavior as labour companion.

The Self-Care of Heart Failure Index version 7.2: Further psychometric testing

Clinicians and researchers need valid and reliable instruments to evaluate heart failure (HF) self-care. The Self-Care of Heart Failure Index (SCHFI) is a theoretically driven instrument developed for this purpose. The SCHFI measures self-care with three scales: self-care maintenance, measuring behaviors to maintain HF stability; symptom perception, measuring monitoring behaviors; and self-care management, assessing the response to symptoms. After the theory underpinning the SCHFI was updated, the instrument was updated to version 7.2 but it was only tested in the United States. In this study we tested the psychometric characteristics (structural and construct validity, internal consistency, and test-retest reliability) of the SCHFI v.7.2 in an Italian population of HF patients. We used a cross-sectional design to study 280 HF patients with additional data collected after 2 weeks for test-retest reliability. Adults with HF (mean age 75.6 (±10.8); 70.8% in New York Heart Association [NYHA] classes II and III) were enrolled from six centers across Italy. Confirmatory factor analysis showed supportive structural validity in the three SCHFI v.7.2 scales (CFI from 0.94 to 0.95; RMSEA from 0.05 to 0.07). Internal consistency reliability estimated with Cronbach's α and composite reliability ranged between .73 and .88; test-retest reliability ranged between 0.73 and 0.92. Construct validity was supported with significant correlations between the SCHFI v.7.2 scale scores and quality of life, brain natriuretic peptide levels and NYHA class. This study further supports the psychometric characteristics of the SCHFI v.7.2, illustrating that it can be used in clinical practice and research also in an Italian population.

Psychometric characteristics of the caregiver contribution to self-care of chronic illness inventory

AIM

The purpose of the this study was to test the factorial structure, internal consistency reliability and concurrent validity of the Caregiver Contribution to Self-Care Chronic Illness Inventory.

BACKGROUND

Existing measures of caregiver contribution to self-care are disease-specific or behaviour-specific; no generic measures exist.

DESIGN

A cross-sectional study.

METHOD

Between April 2017 - December 2018, we enrolled a convenience sample of 358 patients with chronic illnesses and their caregivers. Patients completed the Self-Care of Chronic Illness Inventory while caregivers completed the Caregiver Contribution to Self-Care of Chronic Illness Inventory, a modification of the Self-Care of Chronic Illness Inventory, which includes three scales as follows: the Caregiver Contribution to Self-Care Maintenance, the Caregiver Contribution to Self-Care Monitoring and the Caregiver Contribution to Self-Care Management. Of each scale, we tested the factorial structure with confirmatory factor analysis and reliability with the factor score determinacy coefficient, the global reliability index for multidimensional scale and Cronbach's alpha. Also, we used Pearson's correlations for concurrent validity purposes.

RESULTS

Confirmatory factor analysis supported the two-factor structure of the Caregiver Contribution to Self-Care Maintenance and Management scales and the one-factor structure of the Caregiver Contribution to Self-Care Monitoring scale. A simultaneous confirmatory factor analysis on the combined set of items supported the more general model (Comparative Fit Index = 0.933). Reliability estimates ranged between 0.701 and 0.961 across the three scales. Concurrent validity of Caregiver Contribution to Self-Care of Chronic Illness Inventory with the Self-Care of Chronic Illness Inventory was not sufficiently supported since weak correlations were found.

CONCLUSION

The Caregiver Contribution to Self-Care of Chronic Illness Inventory is valid and reliable and can be used in clinical practice and research.

IMPACT

The Caregiver Contribution to Self-Care of Chronic Illness Inventory is an useful instrument to evaluate the extent to which caregivers contribute to patient self-care in chronic illnesses.

Spanish Version of the Attitude Towards Euthanasia Scale

Euthanasia is undoubtedly the protagonist of many of the debates around the end of life both among health staff and in the general population. Considering that nurses provide care for terminally ill patients and support families and patients in their final days, it is essential to know their attitudes towards euthanasia. The aims of the study were to adapt and validate the Attitude Towards Euthanasia scale to a Spanish context, to test the dimensionality and to estimate the reliability of the scale. A cross-sectional study was conducted with a non-probabilistic sample of Spanish health-workers of 201 in a University Hospital in Ciudad Real. A self-reported socio-demographic questionnaire and the Euthanasia Attitude Scale were used for data collection. The psychometric properties of the scale were assessed, including reliability and validity using an exploratory and confirmatory factor analysis. Cronbach's alpha of the Attitude Towards Euthanasia scale was α = 0.827 and McDonald's Omega = 0.903. The range of items of homogeneity was from 0.205 to 0.685. For the different exploratory factor analyses carried out, the Bartlett's test of sphericity was p < 0.001 and the sample index value of Kaiser-Meyer-Olkin was over 0.802. in all cases. We present the factorial weights for three models: The first one assumes a unidimensional solution, the second model was composed by three factors and the third model was composed by four factors. In the confirmatory factor analysis, the three models presented an acceptable fit index. The Attitude Towards Euthanasia scale adaptation to a sample of Spanish health workers has shown, with some limitations, appropriate psychometric properties. There have been several differences between the original factorial solution. It would be necessary to replicate the study to reinforce the findings about the number of factors of the scale.

Psychometric Testing of the Revised Self-Care of Heart Failure Index

BACKGROUND

Self-care is essential in people with chronic heart failure (HF). The process of self-care was refined in the revised situation specific theory of HF self-care, so we updated the instrument measuring self-care to match the updated theory. The aim of this study was to test the psychometric properties of the revised 29-item Self-Care of Heart Failure Index (SCHFI).

METHODS

A cross-sectional design was used in the primary psychometric analysis using data collected at 5 sites in the United States. A longitudinal design was used at the site collecting test-retest data. We tested SCHFI validity with confirmatory factor analysis and predictive validity in relation to health-related quality of life. We tested SCHFI reliability with Cronbach α, global reliability index, and test-retest reliability.

RESULTS

Participants included 631 adults with HF (mean age, 65 ± 14.3 years; 63% male). A series of confirmatory factor analyses supported the factorial structure of the SCHFI with 3 scales: Self-Care Maintenance (with consulting behavior and dietary behavior dimensions), Symptom Perception (with monitoring behavior and symptom recognition dimensions), and Self-Care Management (with recommended behavior and problem-solving behavior dimensions). Reliability estimates were 0.70 or greater for all scales. Predictive validity was supportive with significant correlations between SCHFI scores and health-related quality-of-life scores.

CONCLUSIONS

Our analysis supports validity and reliability of the SCHFI v7.2. It is freely available to users on the website: www.self-care-measures.com.

Validity and Reliability of the Antepartum Gastrointestinal Symptom Assessment Instrument

OBJECTIVE

To examine the psychometric properties of the nine-item Antepartum Gastrointestinal Symptom Assessment (AP-GI-SA) instrument.

DESIGN

Single-group prospective design.

SETTING

Urban prenatal clinic serving a diverse population.

PARTICIPANTS

Convenience sample of 45 pregnant women.

METHODS

Participants completed the AP-GI-SA before a scheduled prenatal care appointment. We used Bayesian structural equation modeling to evaluate the construct validity of the scale and assessed known-groups validity. We assessed reliability through maximal reliability coefficient estimate and measured internal consistency with Cronbach's alpha coefficient.

RESULTS

Participants completed the instrument in 2 minutes or less. Construct validity was supported by confirmatory factor analysis (posterior predictive p value = 0.49, gamma-hat = 0.970, and root mean square error of approximation = 0.065), which indicated that the single-factor model is a plausible data-generative model for GI symptoms. The maximal reliability coefficient of 0.75 and Cronbach's alpha coefficient of 0.67 supported reliability. Average AP-GI-SA scores were the highest for women in the third trimester. Of all nine GI symptoms, heartburn in the third trimester received the highest score.

CONCLUSION

Our findings provide preliminary support for the validity and reliability of the AP-GI-SA. The instrument may be used as a measure in intervention studies where GI symptoms of pregnancy are an outcome. The AP-GI-SA could also be useful in clinical settings to quickly evaluate GI symptoms.

Validity and reliability of the self-care of hypertension inventory (SC-HI) in a Brazilian population

BACKGROUND

Poor self-care in patients with hypertension is associated with worse patient outcomes. The Self-Care of Hypertension Inventory (SC-HI) measures self-care in patients with hypertension and includes three scales: self-care maintenance, which measures adherence to prescribed treatments and behaviors; self-care management, which evaluates the responses to signs and symptoms of high blood pressure; and self-care confidence, which measures self-efficacy in dealing with the entire process.

OBJECTIVE

To test the psychometric characteristics of the Brazilian version of the SC-HI.

METHODS

We enrolled a sample of 360 patients with hypertension and performed confirmatory factor analysis (CFA) and exploratory factor analysis (EFA) to test the factorial structure of the SC-HI and computed the factor score determinacy coefficient to evaluate the SC-HI internal consistency reliability.

RESULTS

The sample was predominantly female (65%), mean age of 65 years (SD = 10), white (70%). The self-care maintenance scale resulted in a unidimensional scale, with supportive fit indices (CFI = 0.901, RMSEA = 0.048); the self-care management did not reflect the original factorial structure and had unsupportive fit indices. EFA showed a different factorial solution in reference to the original study. Finally, the self-care confidence scale resulted in a unidimensional scale with supportive fit indices (CFI = 0.940, RMSEA = 0.093). The reliability of the self-care maintenance, management, and confidence scales resulted in factor score determinacy coefficients of 0.83, 0.78, and 0.97 respectively.

CONCLUSION

This study shows that the SC-HI is a valid and reliable tool to measure self-care in patients with hypertension among the Brazilian population.

Creating a Caregiver Benefit Finding Scale of Family Caregivers of Stroke Survivors: Development and Psychometric Evaluation

In recent years, increased attention has been paid to the benefit finding of family caregivers due to the important role they play. Although some instruments measure benefit finding of caregivers, they do not comprehensively address it in terms specific to the family caregivers of stroke survivors, who require long-term, consistent care. This study is the first effort to develop a comprehensive Caregiver Benefit Finding Scale for the family caregivers of stroke survivors in a Chinese cultural setting. First, 50 items were extracted from a systematic literature review, and a semi-structured interview was conducted with 20 stroke family caregivers to develop the preliminary version of the scale (Version 1). Second, Delphi procedures with 20 experts were used to revise the first version and create Version 2 (37 items). Another six experts were recruited for content validation. Item content validity index (I-CVI) values ranged from 0.83 to 1.00, and the value of the scale CVI was 0.97. Third, 309 family caregivers completed the Version 2 questionnaire and the Chinese version of the Positive Aspects of Caregiving. Two weeks later, 35 family caregivers once again completed the questionnaires. An exploratory factor analysis produced four components (personal growth, health promotion, family growth, and self-sublimation) and 26 items for Version 3 (the cumulative proportion variance was 74.14%). Subsequently, 311 family caregivers completed Version 3. A confirmatory factor analysis confirmed the structure. The goodness of fit index (GFI) = 0.921, adjusted GFI = 0.901, normal fit index = 0.951, incremental fit index = 0.990, comparative FI = 0.990, and the root mean square error of approximation = 0.02 were within the acceptable range. Criterion-related validity was equal to 0.803. The model-based internal consistency index was 0.845 and the values of the Cronbach'α coefficient of the four dimensions were 0.885-0.953. The split-half reliability was 0.92, and the test-retest reliability was 0.994. These findings provide preliminary evidence of the validity and reliability of the Caregiver Benefit Finding Scale. The scale can help researchers and clinicians to achieve a more comprehensive understanding of stroke family caregivers' positive experience. This understanding is necessary for future efforts to address issues in benefit finding by targeting the underlying mechanism and intervention.

Cross-Cultural Adaptation and Reliability Testing of Chinese Version of the Living with Medicines Questionnaire in Elderly Patients with Chronic Diseases

BACKGROUND

The Living with Medicines Questionnaire (LMQ-3) is a reliable, valid instrument used to assess the medication-related burden of patients with chronic disease using long-term medication, but it has not been used in China.

PURPOSE

To translate and cross-culturally adapt the LMQ-3 into Chinese and assess its reliability and validity among elderly patients with chronic disease.

METHODS

After translation and back-translation, views from an expert group and cognitive interviews with elderly persons using multiple medicines were used to ensure the cultural relevance of the LMQ-3. Then, 412 participants aged 60-92 years were recruited from three communities in Zhengzhou to complete the instrument. Item analysis, internal consistency, content validity, exploratory factor analysis (EFA) and reliability testing were performed.

RESULTS

Item analysis identified nine items for possible removal, which were discussed with the originating team. Internal consistency testing confirmed the suitability of removing two of these items, which concurred with the views of the expert group and cognitive interviews. All other items were retained, but four were modified for clarification without changing their meaning, resulting in a 39-item instrument. EFA of this 39-item measure yielded an eight-factor model, similar to the English version. Cronbach's alpha of the Chinese version of LMQ-3 (C-LMQ-3) for elderly patients with chronic diseases was 0.855, and alpha values for the eight domains ranged from 0.822 to 0.932. Test-retest reliability was satisfactory, with ICC values for the eight domain scores ranging from 0.751 to 0.881.

CONCLUSION

With only minor modifications compared to the English version, the 39-item C-LMQ-3 is a valid tool, with adequate reliability, which can be used to assess the medication-related burden of long-term use of multiple medicines in elderly patients in China.

Cross-cultural adaptation and validation of questionnaire for knowledge, attitudes, and behavioral intentions in Italian nurses with regard to provision of artificial nutrition and hydration to patients terminally ill with cancer

OBJECTIVES

Decision-making on artificial nutrition and hydration for patients terminally ill with cancer can be influenced by nurses' knowledge, attitudes, and behavioral intentions. A comprehensive 57-item questionnaire including six sections on the knowledge, attitudes, and behavioral intentions in providing artificial nutrition and hydration to patients terminally ill with cancer has been developed and used in Taiwan. However, the questionnaire needs further psychometric testing and adaptation for other cultures. This study aimed to cross-culturally adapt the questionnaire within the Italian cultural context and test its psychometric properties.

METHODS

The questionnaire was translated into Italian and cross-culturally adapted per the recommendations by Beaton. A panel of 10 experts assessed content validity. A multicenter cross-sectional study was conducted with 411 nurses to test its psychometric properties. Dimensionality and construct validity were assessed through exploratory and confirmatory factor analyses. Reliability was estimated by composite ω and traditional methods, such as the Kuder Richardson formula-20 and Cronbach's α coefficients.

RESULTS

The overall content validity index was 0.85. A confirmatory factor analysis was conducted for the knowledge section and the four attitudes sections. A preliminary analysis for the behavioral intentions section yielded non acceptable results. The internal consistency of the scales was adequate (range, 0.64-0.93).

CONCLUSIONS

This study constituted a notable advancement in the psychometric testing of the tool, and provides evidence that the Italian version of the questionnaire has acceptable psychometric characteristics for the sections on knowledge and attitudes.

Fear of Crime, Racial Bias, and Gun Ownership

Firearm-related violence is a significant threat to public health and safety in America. However, research highlights a critical disparity in firearm-related deaths by race. Researchers often cite racial bias as a contributing factor for the racial disparity in firearm-related deaths. To provide a foundation for potential social work interventions, the present article discusses the results of an assessment of whether explicit racial biases toward four racial and ethnic groups (white, black, Asian, Hispanic/Latino), fear of crime, and the quantity and quality of interactions with neighbors of a different race are predictors of gun ownership. Findings suggest that explicit racial bias toward black, Asian, and Hispanic/Latino individuals is a significant predictor of gun ownership. Fear of crime and more frequent interactions with neighbors of a different race are also significant predictors of gun ownership. Taken as a whole, findings suggest that gun owners are more likely to be more vigilant toward people of color because of stereotypical assumptions that racial and ethnic minorities are more likely to be involved with crime. Social work practice and policy implications include developing interventions aimed at reducing implicit bias and identifying policies that are associated with lower levels of implicit bias among gun owners.

How do we assess musicians' musculoskeletal symptoms?: a review of outcomes and tools used

Recent reviews of musicians' musculoskeletal symptoms (MSS) have reported heterogeneity in the outcomes reported and data collection tools used, making it difficult to compare and synthesise findings. The purpose of this present review was to improve the consistency of future research, by documenting the outcomes reported in recent studies of musicians' MSS and the data collection tools used. All English language, peer-reviewed studies, published 2007-2016 that reported musicians' self-reported MSS outcomes were identified. Details of the types of outcomes reported and the tools used were extracted, and synthesised descriptively. A range of MSS outcomes were reported, including MSS with a temporal relationship to activities performed, and the consequences of symptoms. Only 24% of studies used standardised questionnaires, with the Nordic Musculoskeletal Questionnaire (NMQ) being the most commonly used. To improve the homogeneity of outcomes and data collection tools when investigating musicians' MSS, we recommend using the NMQ, where appropriate. Recall periods of 12-months and 7-d are the most appropriate for prevalence, and 7-d recall periods for ratings. Importantly, outcomes and the tools used to collect data should be reported in sufficient detail to ensure that the study can be replicated, critiqued, and accurately interpreted.

The Self-Care in Chronic Obstructive Pulmonary Disease Inventory: Development and Psychometric Evaluation

This study developed two instruments, the Self-Care in Chronic Obstructive Pulmonary Disease (COPD) Inventory (SC-COPDI) and the COPD-Self-Care Self-Efficacy Scale (SCES), and tested their psychometric properties on a convenience sample of 498 patients from Northern, Central, and Southern Italy. First, the domains and the items of the SC-SCOPDI were generated based on the middle-range theory of self-care of chronic illness, comprising the dimensions of self-care maintenance, self-care monitoring, and self-care management, and the SCES-COPD was developed accordingly. Second, we assessed the content validity of each scale. Third, we conducted a multicenter cross-sectional study to test their structural validity, convergent and discriminative validity, internal consistency, and test–retest reliability. The theoretical dimensions of the two instruments were confirmed through confirmatory factor analysis. Convergent validity was demonstrated by the correlation among the three self-care scales and the Self-Efficacy Scale, and discriminative validity by higher self-care scale scores in individuals with greater COPD severity and poorer health status. The global reliability index ranged from .78 to .92 for all scales. The intraclass correlation coefficients were higher than .70. Further studies are needed to confirm the psychometric properties of the two instruments in different COPD populations and countries to extend their use in clinical practice.

Psychometric testing of the Caring Behaviors Inventory for nursing students

AIM AND OBJECTIVE

To test the psychometric properties of the nursing students' version of the 24-item Caring Behaviours Inventory.

BACKGROUND

Caring is at the heart of nursing and should also be a core value in nursing education. Caring can be manifested through measurable behaviours. The Caring Behaviors Inventory is a valid and reliable measure of nurses' caring behaviours in clinical settings. It has already been used among nursing students, but it needs more psychometric testing.

DESIGN

Cross-sectional validation study.

METHOD

The questionnaire was filled in by 300 undergraduate nursing students at two Italian universities in May 2016. Exploratory factor analysis was conducted using Mplus maximum likelihood with GEOMIN oblique rotation. A multifaceted approach was used to evaluate the model fit. The STROBE checklist for cross-sectional studies was followed.

RESULTS

Four dimensions were identified: "being with," "doing with competence," "responding to individual needs" and "providing effective care." Adequate fit indices and high reliability of the factors were found. Correlations between factors were positive and significant.

CONCLUSION

This study makes it possible to use the same tool to compare the caring practices perceived by students, nurses and patients. Further studies with bigger samples could be stratified to investigate the associations between caring levels and student characteristics. The Caring Behaviors Inventory can be used to call attention to caring in nursing education, helping to make this concept less elusive.

RELEVANCE TO CLINICAL PRACTICE

The effective self-assessment of nursing students' caring behaviours offers opportunities for reflection on their caring practice. This could improve the caring level of their behaviours in clinical practice and help them to become caring nurses in the future.

Psychometric evaluation of the Heart Failure Somatic Perception Scale in a European heart failure population

Background:

The Heart Failure Somatic Perception Scale (HFSPS) is a four-factor instrument used to assess how bothersome are 18 physical signs and symptoms of heart failure. To date, construct validity and reliability of the HFSPS have been evaluated in only one American study and never in a European population.

Aim:

To evaluate psychometric properties (validity and reliability) of the HFSPS in a European heart failure population.

Methods:

This was an Italian multicentre study in which the HFSPS factorial structure was assessed using confirmatory factor analysis. Criterion related validity of the HFSPS was evaluated by correlating its factor scores with the Kansas City Cardiomyopathy Questionnaire (KCCQ) scores using Pearson’s r. The HFSPS internal consistency reliability was evaluated using the factor score determinacy coefficient, Cronbach’s α and model-based internal consistency index.

Results:

Most of the participants ( n=321) were male (56.6%), with a mean age of 71.48 years (SD, 12.75) and in New York Heart Association class II (61.8%). The confirmatory factor analysis, testing the original HFSPS four-factor structure (dyspnoea, chest discomfort, early and subtle, and oedema), resulted in the following supportive fit indices: χ2 (126, N=321)=337.612, p<0.001, comparative fit index =0.920, Tucker–Lewis index =0.903, root mean square error of approximation =0.072 and standardized root mean square residual =0.045. With regard to the criterion related validity, all the correlations with the KCCQ were statistically significant. The HFSPS reliability resulted in factor score determinacy coefficients ⩾ 0.87 and Cronbach’s α ⩾ 0.75, with the exception of the two-item chest discomfort subscale; the model-based reliability coefficient was 0.914.

Conclusion:

The validity and reliability of the HFSPS were supportive in this European sample. The HFSPS can be used to assess how bothersome heart failure signs and symptoms are in order to improve their management.

Modified Research Utilization Questionnaire: Development and Validation Study among Italian Nurses

PURPOSE

The purpose of this study was to develop the modified research utilization questionnaire (M-RUQ) and to establish its content and face validity, construct validity, and reliability.

METHODS

This study has a multiphase (three phases), methodological, and cross-sectional design. First, research utilization questionnaire (RUQ) was translated into Italian, which is the target language to develop the M-RUQ. Second, the RUQ psychometric proprieties were assessed using exploratory factorial analysis to identify ambiguous or problematic items (e.g., cross-loadings) (cross-sectional sampling A). The RUQ modification (i.e., item deleting, wording modification, and scoring procedure) represented the development of the M-RUQ among Italian nurses. The third phase was aimed to confirm the construct validity of the M-RUQ and to test its stability and internal consistency (cross-sectional sampling B).

RESULTS

This study's findings show that M-RUQ has a three-dimensional structure and a total of 22 items. The M-RUQ shows evidence of validity and reliability. Precisely, the factorial structure coming from an exploratory factorial analysis on the first sample (n = 504) was confirmed by a final model of confirmatory factorial analysis (CFA) on a second sample (n = 362). The final CFA model showed adequate goodness of fit, where all the factor loadings showed values higher than .40. Cronbach's α was satisfactory for each domain and for the overall scale. Furthermore, the M-RUQ showed good stability described by the test-retest.

CONCLUSION

The M-RUQ should be used to assess research utilization among nurses for educational or research purposes to address the practice. Further research about its validity and reliability is suggested.
