The Appraisal of Self-Care Agency Scale - Revised (ASAS-R): adaptation and construct validity in the Brazilian context

A web-based educational therapy intervention associated with physical exercise to promote health in fibromyalgia in Brazil: the Amigos De Fibro (Fibro Friends) study protocol

BACKGROUND

Health education is one of the main items to enable health promotion to patients with fibromyalgia. The objective of the study "Amigos de Fibro (Fibro Friends)" is to evaluate the impact of an educational intervention associated with physical exercise based on the web in promoting health and quality of life of patients with fibromyalgia in Brazil.

METHODS

A study with a randomized controlled trial approach will be carried out. The sample will consist of 24 participants, divided into two groups, with 12 individuals each. The experimental group will participate in meetings with lectures, debates, conversation rounds and exercises by a multidisciplinary team. Physical exercises will also be performed in an online environment. On the other hand, the control group will receive an e-book of education and self-care. Primary outcomes will be quality of life. The secondary outcomes will be sociodemographic and health profile, pain intensity, sleep quality, self-care agency, usage and costs of health and social care services, viability of the program and program participation. In addition, a qualitative evaluation process will be carried out with the participants. After the intervention, the data of both groups will be collected again, as well as after 3, 6, and 12 months to verify the effect and the maintenance of the intervention.

DISCUSSION

The results will provide data for studies to consider the use of this tool in the future by professionals working in the field of rheumatology.

TRIAL REGISTRATION

The protocol was registered in the Brazilian Registry of Clinical Trials RBR-3rh759 ( https://trialsearch.who.int/Trial2.aspx?TrialID=RBR-3rh759 ). Date of registration: 07/02/2020].

The Appraisal of Self-Care Agency Scale-Revised (ASAS-R): Reliability and Validity among Portuguese Medical Students

Self-care agency plays an important role in an individual's health. Considering the particularities of their education, it can be a protective factor for the mental health of medical students. This study aims to validate the Portuguese version of the Appraisal of Self-care Agency Scale-Revised (ASAS-R) in Portuguese medical students. A cross-sectional, quantitative, and analytical online study was conducted between 23 April 2021, and 15 July 2021. Exploratory factor analysis (EFA) was performed to test the internal structure of the ASAS-R. Correlations with the SHS (Subjective Happiness Scale), SWLS (Satisfaction with Life Scale), and MHI (Mental Health Inventory) were calculated using Pearson's coefficient so as to test convergent validity. Internal consistency was evaluated using inter-item correlation, corrected item-total correlation, and Cronbach's alpha. The total sample included 781 individuals. EFA yielded a 3-factor solution accounting for 53.9% of the explained variance. Pearson's coefficients obtained between the 3 factors of ASAS-R and the total scores of the 3 construct-related scales demonstrated adequate convergent validity. Total Cronbach's alpha value was 0.85, while the Cronbach's alpha of the three factors was 0.81, 0.55, and 0.83, respectively. This study demonstrated that ASAS-R is a valid and reliable instrument for measuring self-care agency among Portuguese medical students.

Self-Care and Sense of Coherence: A Salutogenic Model for Health and Care in Nursing Education

Background: Effective advocacy on self-care and the enhancement of a sense of coherence among nurses don’t only benefit control over one’s health and personal performance, but it may have a direct impact on clinical care and on the entire healing system. In this regard, nursing curricula grounded on a salutogenic model of health (SMH) operate with strategies to engage students in self-care and contribute to improving their mental health and wellbeing. The aim of this study was to explore the relationships between self-care agency and a sense of coherence as dependent variables and the age and self-reported academic performance as independent variables in nursing assistant students. Methods: For this cross-sectional study, data were collected from a full sample of 921 Certified Nursing Assistant (CNA) Spanish students. A self-administered questionnaire, including sociodemographic variables, the ‘appraisal of self-care agency’ (ASA), and the ‘sense of coherence’ (SOC) constructs, was administered. Results: Results: Older participants presented significantly stronger values of both constructs. Apart from a significant and positive correlation between ASAS and SOC, ANOVA analyses indicate signif-icant differences in terms of academic performance according to different ASAS and SOC de-grees. Conclusion: The findings of this study endorse the assumption that there is a consistent relationship between ASA and SOC constructs that might, indeed, have a potential effect on stu-dents’ academic performance. In practical terms, it seems relevant to try to recognise the stu-dents’ self-care agency and the sense of coherence as forceful predictive variables of mental health and wellbeing, in addition to academic success as a strength implied in the future career achievement.

Self-care appraisal in nursing assistant students: Adaptation, validation and psychometric properties of the Spanish ASAS

The core implication of nursing professionals’ labor is promoting self-care and foster well-being among healthcare service users. The beginning of the healing process starts with the provider, and self-care habits are needed to positively impact on patients’ care outcomes at different spheres. Overall, current literature supports the idea that nurses’ personal self-care should be a necessary skill to be expected in their professional role. In this regard, the Appraisal of Self-care Agency Scale (ASAS) is a worldwide known instrument aimed at assessing the ability to engage in self-care. However, it has never been tested in the Spanish context before, and much less in nursing practitioners or apprentices. The aim of this study was to translate, adapt and validate the ASAS for Spanish nursing apprentices, assessing its dimensionality, psychometric properties and convergent validity by means of the Sense of Coherence (SOC-13) questionnaire. Methods: Data were collected from a random sample of 921 Certificated Nursing Assistant (CNA) Spanish students and was analyzed trough confirmatory factor analyses via structural equation models. The core ASAS construct and its subscales were correlated with the SOC-13 scores. Results: Fair psychometric properties for the questionnaire were set. Also, SEM models endorse the validity and reliability of the four-factor dimensionality of the Spanish adaptation of the ASAS, whose associations to SOC scores were coherent and significant. Conclusion: This study allowed to establish that the Spanish version of the ASAS might be a useful tool for addressing self-care-related issues among nursing apprentices, a key population for promoting both their own and patients’ health and welfare through healthy and care-related behaviors.

Self-care agency and associated factors in postmenopausal women

OBJECTIVE

The aging process in women is marked by several changes, including the transition to menopause. The evaluation of self-care management is essential and has great relevance for public health. The aim of the present study was to evaluate self-care management and associated factors in postmenopausal women.

METHOD

This study was a cross-sectional study performed with 260 postmenopausal women who attended routine consultations at the Menopause Outpatient Clinic of the Hospital of the State University of Campinas-SP. Women aged 50 years or older with amenorrhea for at least 12 months were included. The women were interviewed by a researcher during the routine consultation, and the self-care agency assessment was performed using the Appraisal of Self-Care Agency Scale-Revised questionnaire.

RESULTS

The average total self-care score for the women in this study was 62.27 (± 9.64). Higher Appraisal of Self-Care Agency Scale-Revised scores were associated with performing outdoor activities, better self-perceived health, and a higher score on knowledge about vitamin D. Active smoking was associated with a lower self-care score.

CONCLUSION

We observed that the self-care management of postmenopausal women was satisfactory and was associated with lifestyle, self-perceived health, and knowledge about vitamin D.

Self-Care Practice and Associated Factors among Hypertensive Patients in Debre Tabor Referral Hospital, Northwest Ethiopia, 2020

Background

Hypertension prevalence is continuously rising and is projected to be 1.56 billion cases by the year 2025. Despite the great progress made in the treatment of hypertension, many patients still do not achieve optimal results and experience devastating complications due to uncontrolled high blood pressure.

Objective

The aim of this study is to assess self-care practice and associated factors among hypertensive patients.

Methods

An institution-based cross-sectional study was conducted at Debre Tabor Referral Hospital, Northwest Ethiopia, from October to November 2020. A single population proportion formula and systematic random sampling technique was used to recruit 392 study participants. The data were entered to Epi-Info software version 7.1 and then exported to SPSS version 23 for analysis. A descriptive statistic was expressed as percentage, frequency, and mean. Finally, multivariable logistic regression was used to identify factors associated with dependent variable using a p value of <0.05.

Results

A total 392 eligible hypertensive patients participated in the study. The self-care practice among hypertension patients was found to be 54.1%. Urban residency (AOR = 2.17; 95% CI, 1.2-3.9), social support (AOR = 2.12; 95% CI, 1.13-3.39), good knowledge (AOR = 1.83; 95% CI, 1.15-2.91), age between 40 and 64 (AOR = 3.15; 95% CI, 1.19-8.3), age ≥65 (AOR = 3.81; 95% CI, 1.35-10.7), and stress control (AOR = 1.6; 95% CI, 1.06-2.67) were predictors of hypertension self-care practice. Conclusion and Recommendation. The study revealed that almost one out of two hypertension patients had good hypertension self-care practice. Good social support, age greater than 40 years, urban residency, good basic knowledge, and having stress control were positively associated with hypertensive self-care practice.

Effects of a six-week mobile app versus paper book intervention on quality of life, symptoms, and self-care in patients with fibromyalgia: a randomized parallel trial

BACKGROUND

The ProFibro application (app) was developed as a Mobile Health resource to promote self-care in fibromyalgia management.

OBJECTIVE

This study aimed to assess the effects of the use of the ProFibro app for six weeks compared to the use of a traditional paper book of similar content to improve health-related quality of life, symptoms, and self-care agency in individuals with fibromyalgia.

METHODS

Forty individuals with fibromyalgia were included in this randomized, single-blind, parallel trial. One group received intervention content using the ProFibro app on a smartphone while the other received similar information using a paper book. Participants were assessed at baseline and after six weeks. The primary outcome was the Revised Fibromyalgia Impact Questionnaire. Secondary outcomes were Widespread Pain Index, Pain Visual Analog Scale, Symptom Severity Scale, and Appraisal of Self-Care Agency Scale - Revised.

RESULTS

No differences in changes were found between groups at the end of the treatment for any outcome. Both groups showed improvements in symptom severity.

CONCLUSIONS

The use of the ProFibro app for six weeks was not more effective than the use of a traditional paper book with similar content for health-related quality of life, symptoms, or self-care agency in individuals with fibromyalgia. Both groups showed improvements from baseline on severity of symptoms, suggesting that the self-care program using a mobile app or a paper book may be beneficial for individuals with fibromyalgia.

Avaliação do agenciamento de autocuidados e sua associação com sintomas e qualidade de vida em indivíduos com fibromialgia

RESUMO A fibromialgia (FM) é uma condição de alta prevalência e que causa desconforto físico, sofrimento mental e comprometimento nas relações sociais. Assim, o autocuidado pode ser um aspecto determinante para melhorar a qualidade de vida de indivíduos com FM, pois está relacionado ao ato de se investir de poder. Portanto, o objetivo deste estudo foi avaliar o agenciamento do autocuidado de indivíduos com FM e verificar a associação do autocuidado com variáveis sociodemográficas, sintomas e qualidade de vida. Participaram do estudo 40 indivíduos com FM, que preencheram os critérios diagnósticos do Colégio Americano de Reumatologia de 2010. O autocuidado foi avaliado pela Escala de Avaliação de Agenciamento de Autocuidados Revisada (EAAA-R), a intensidade da dor dos pacientes foi verificada pela Escala Visual Analógica (EVA) e pelo Índice de Dor Generalizada (IDG), enquanto a severidade dos sintomas foi avaliado pela Escala de Severidade dos Sintomas (SS) e a qualidade de vida pelo Questionário de Impacto da Fibromialgia Revisado (QIF-R). Utilizamos o coeficiente de correlação de Pearson (dados paramétricos) e coeficiente de correlação de Spearman (dados não paramétricos), com nível de significância α<0,05. Os resultados mostram valores médios para o agenciamento do autocuidado (52,75±10,25), intensidade da dor (5,84±2,16), IDG (13,32±3,78), SS (9,30±1,68), e QIF-R (63,98±17,26). Houve associação do autocuidado com a classe social (r=0,391) e associação com domínios do QIF-R: função (r=-0,338), impacto geral (r=-0,315), sintomas (r=-0,332) e escore total (r=-0,375). O estudo sugere moderado agenciamento de autocuidado e fraca associação do autocuidado com a qualidade de vida e com a classe social em indivíduos com fibromialgia.

Alcohol and Drug Use in European University Health Science Students: Relationship with Self-Care Ability

Background: Drug abuse in university students is an emerging social and health issue. The present study assesses alcohol and abuse of other illicit drugs and the adverse consequences related to such use and its relationship with self-care agency among European university students. Methods: A multicenter cross-sectional study was performed among 592 European students from different health science degrees. The screening of alcohol abuse was evaluated with the Alcohol Use Disorder Test (AUDIT), and the screening for substance-related risks and problems was conducted with the Car, Relax, Alone, Forget, Friends, Trouble (CRAFFT) screening test. We analyzed the relationship of substance abuse with self-care agency, assessed by the Appraisal of Self-Care Agency Scale (ASA). Results: 51.4% of the surveyed students reported alcohol intake, 16.6% of the students consumed both alcohol and cannabis, 1.6 % reported alcohol and other illicit drugs, and 3.7% consumed alcohol, marijuana, and other illicit drugs (73.3% of students reported alcohol intake alone or together with cannabis/hashish and/or other illicit drugs). The self-care agency scores were significantly different among groups in relation to certain sociodemographic factors such as gender (p = 0.008) and country of residence (p = 0.031). The self-care agency scores significantly correlated (p = 0.001) with the personal motivations and consequences related to the consumption of drugs of abuse evaluated by the CRAFFT screening tool. Within the ASA domains, the most significant effects were observed regarding the subdomains of resources, awareness, and health behaviors. Conclusions: Self-care agency should be promoted to counteract the health and social consequences of the consumption of drugs of abuse among university students who will be future health care professionals.

Functional and self-care capacity of people with multiple sclerosis

Objective:

describe the self-care and functionality levels of patients with multiple sclerosis and determine whether sociodemographic, clinical and functional variables interfere with self-care and/or functionality.

Method:

correlational, cross-sectional study with a quantitative approach performed with individuals in outpatient follow-up. We collected sociodemographic and clinical data and applied the Appraisal of Self-care Agency Scale, the Barthel index, the Lawtton and Brody Scale, and the instrument to investigate the performance in Advanced Activities of Daily Living. We performed descriptive and inferential analysis.

Results:

most patients were classified as “having self-care” (82.14%); with moderate dependence (51.19%) for the basic activities of daily living, partial dependence for the instrumental activities of daily living (55.95%), and more active for the advanced activities of daily living (85.71%). Patients with longer disease duration had a higher number of disabilities and, in those with better socioeconomic and educational profile, the functionality was better.

Conclusion:

disease duration was strongly correlated with a higher number of disabilities and better socioeconomic and educational profiles showed to be protective factors for functionality. Care planning should consider the needs observed by the multidisciplinary team, stimulating the development of self-care, functionality and sociability.

Hypertension self-care practice and associated factors among patients in public health facilities of Dessie town, Ethiopia

Background

Hypertension self-care practice is essential for blood pressure control and reduction of hypertension complications. Nevertheless, we know little concerning hypertension self-care practice in Ethiopia. The purpose of this study was to assess hypertension self-care practice and associated factors among patients in public health facilities in Dessie town, Ethiopia.

Methods

In this cross-sectional study, 309 hypertensive patients (mean age 58.8 years, 53.4% women) completed the interviewer-administered questionnaire in Amharic language. Descriptive and logistic regression analyses were conducted using SPSS version 22.

Result

The mean score for hypertension self-care was 37.7 ± 8.2 and 51% scored below the mean. Divorced participants (AOR = 0.115, 95% CI = 0.026, 0.508, p-value < 0.01) and those who lack source of information (AOR = 0.084, 95% CI = 0.022, 0.322, p-value < 0.01) were less likely to have good self-care practice. But, participants who had convenient place for exercise (AOR = 2.968, 95% CI = 1.826, 4.825, p-value < 0.01), who had good social support (AOR = 2.204, 95% CI = 1.272, 3.821, p-value < 0.01), who had traditional clergy-based teaching (AOR = 2.209, 95% CI = 1.064, 4.584, p-value < 0.05), and who had good self-care agency (AOR = 1.222, 2.956, p-value < 0.05) were more likely to have good self-care practice.

Conclusion

Most of the study participants reported poor self-care practices. Factors associated with hypertension self-care practice are marital status, education, source of self-care information, place for exercise, social support, and self-care agency. Targeted interventions are needed to improve hypertension self-care practice.

Cross-validation of the Self-care Ability Scale for Elderly (SASE) in a sample of Italian older adults

The assessment of self-care among older adults is important as it permits the tailoring of educational interventions directed to prevent health deterioration and contrast the effects of ageing. The Self-care Ability Scale for the Elderly (SASE) was developed to assess the perceived self-care ability in older adults. Its psychometric properties were tested only in Scandinavian countries and China. This research was a cross-validation of the SASE on 402 Italian adults aged 65 and older recruited in hospitals, clinics and homes, from September 2016 to February 2017. We performed exploratory and confirmatory factor analyses on two subsamples and identified three factors, self-care ability to perform ADLs, self-care ability to achieve well-being and self-care ability to set personal goals, with a good model fit (CFI > 0.93; RMSEA = 0.07; SRMR = 0.06). We eliminated four items, however, to improve the structural validity. Internal consistency for the three factors of the Italian version of the SASE (SASE-I) ranged from 0.72 to 0.92. The test-retest reliability indicated good stability of the scale (ICC coefficient = 0.92). We assessed convergent validity by comparing the SASE-I with the Katz Index of Independence in Activities of Daily Living and the Lawton Instrumental Activities of Daily Living Scale, showing moderate-to-strong correlations. In addition, the SASE-I discriminated the self-care ability in groups with different ages, levels of education and settings. Our study produced a 13-item version of the SASE with good psychometric properties that could be recommended for use in clinical practice and research after further validation on different populations and settings.

The Appraisal of Self-Care Agency Scale - Revised (ASA-R): Adaptation and Validation in a Sample of Spanish Older Adults

Self-care agency is an important determinant of healthy aging. The Appraisal of Self-care Agency Scale (ASA-R) (Sousa et al., 2010) is one of the main instrument to assess self-care capacity. The objectives of the study were: 1) to adapt and validate ASA-R scale for use in Spanish population; 2) to examine the dimensionality, validity and reliability; 3) and to establish the convergent validity of ASA-R using a self-reported health measure. The ASA-R Scale and the 12-item Short Form Health Survey (SF-12) were administered to 488 Spanish seniors aged 65 and over. Confirmatory Factor Analysis (CFA) was used to analyze the dimensionality, validity and reliability. Convergent validity was tested by correlating the ASA-R factors with the SF-12 subscales; correlations were significant (p 0.05 (0.436), RMSEA closer to 0 (0.006), SRMR 0.95 (0.996 and 0.995). The results also demonstrated that ASA-R is a reliable and valid instrument. The ASA-R has demonstrated to be a reliable (CR indices > 0.7) and valid (AVE > 0.5) instrument in measuring self-care agency among Spanish older population.

Testing and comparing two self-care-related instruments among older Chinese adults

OBJECTIVES

The study aimed to test and compare the reliability and validity, including sensitivity and specificity of the two self-care-related instruments, the Self-care Ability Scale for the Elderly (SASE), and the Appraisal of Self-care Agency Scale-Revised (ASAS-R), among older adults in the Chinese context.

METHODS

A cross-sectional design was used to conduct this study. The sample consisted of 1152 older adults. Data were collected by a questionnaire including the Chinese version of SASE (SASE-CHI), the Chinese version of ASAS-R (ASAS-R-CHI) and the Exercise of Self-Care Agency scale (ESCA). Homogeneity and stability, content, construct and concurrent validity, and sensitivity and specificity were assessed.

RESULTS

The Cronbach's alpha (α) of SASE-CHI was 0.89, the item-to-total correlations ranged from r = 0.15 to r = 0.81, and the test-retest correlation coefficient (intra-class correlation coefficient, ICC) was 0.99 (95% CI, 0.99-1.00; P<0.001). The Cronbach's α of ASAS-R-CHI was 0.78, the item-to-total correlations ranged from r = 0.20 to r = 0.65, and the test-retest ICC was 0.95 (95% CI, 0.92-0.96; P<0.001). The content validity index (CVI) of SASE-CHI and ASAS-R-CHI was 0.96 and 0.97, respectively. The findings of exploratory and confirmatory factor analyses (EFA and CFA) confirmed a good construct validity of SASE-CHI and ASAS-R-CHI. The Pearson's rank correlation coefficients, as a measure of concurrent validity, between total score of SASE-CHI and ESCA and ASAS-R-CHI and ESCA were assessed to 0.65 (P<0.001) and 0.62 (P<0.001), respectively. Regarding ESCA as the criterion, the area under the receiver operator characteristic (ROC) curve for the cut-point of SASE-CHI and ASAS-R-CHI were 0.93 (95% CI, 0.91-0.94) and 0.83 (95% CI, 0.80-0.86), respectively.

CONCLUSION

There is no significant difference between the two instruments. Each has its own characteristics, but SASE-CHI is more suitable for older adults. The key point is that the users can choose the most appropriate scale according to the specific situation.

Systematic review of measurement properties of self-reported instruments for evaluating self-care in adults

AIMS

The aims of this study were as follows: to identify instruments developed to assess self-care in healthy adults; to determine the theory on which they were based; their validity and reliability properties and to synthesize the evidence on their measurement properties.

BACKGROUND

Many instruments have been developed to assess self-care in many different populations and conditions. Clinicians and researchers should select the most appropriate self-care instrument based on the knowledge of their measurement properties.

DESIGN

Systematic review of measurement instruments according to the protocol recommended by the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) panel.

DATA SOURCES

PubMed, Embase, PsycINFO, Scopus and CINAHL databases were searched from inception to December 2015.

REVIEW METHODS

Studies testing measurement properties of self-report instruments assessing self-care in healthy adults, published in the English language and in peer review journals were selected. Two reviewers independently appraised the methodological quality of the studies with the COSMIN checklist and the quality of results using specific quality criteria.

RESULTS

Twenty-six articles were included in the review testing the measurement properties of nine instruments. Seven instruments were based on Orem's Self-care theory. Not all the measurement properties were evaluated for the identified instruments. No self-care instrument showed strong evidence supporting the evaluated measurement properties.

CONCLUSION

Despite the development of several instruments to assess self-care in the adult population, no instrument can be fully recommended to clinical nurses and researchers. Further studies of high methodological quality are needed to confirm the measurement properties of these instruments.

The Appraisal of Self-Care Agency Scale-Revised (ASAS-R): Reliability and Validity Among Older Chinese People

The study aimed to test the reliability and validity of the Chinese version of the Appraisal of Self-Care Agency Scale-Revised (ASAS-R-CHI). A cross-sectional design was used to conduct this study, and the sample consisted of 1,219 older people, collected by a demographic questionnaire, ASAS-R-CHI and the Exercise of Self-Care Agency (ESCA) scale. The Cronbach's alpha (α) of ASAS-R-CHI was .79, the test-retest correlation was 0.95, and the item-to-total correlations ranged from r = .41 to r = .74. Exploratory factor analysis (EFA) resulted in three factors that explained 65.31% of the total variance; all 15 items had strong factor loadings ranging from 0.54 to 0.91. Confirmatory factor analysis (CFA) indicated the three-factor solution of ASAS-R-CHI had a good fit (x2,chi-square/degree of freedom [CMIN/DF] = 2.61, goodness of fitness index [GFI] = 0.93, adjusted goodness of fit index [AGFI] = 0.92,, comparative fit index [CFI = 0.92], Tucker Lewis index [TLI] = 0.91, root mean square error of approximation [RMSEA] = 0.04, root mean residual [RMR] = 0.02, P-value for test of close fit [PCLOSE] = 0.68). ASAS-R-CHI is a short, reliable, and valid instrument for measuring self-care agency among Chinese older adults.
