Development and psychometric properties of a self-care behaviors scale (SCBS) among patients with rheumatoid arthritis.

ABSTRACT:

Background

The role of self-care behaviors in promoting physical function, pain management, health status and quality of life among patients with Rheumatoid Arthritis (RA) is well documented. However, there is no valid and reliable instrument in the literature to assess such behaviors among the patients. In the present study, we aimed to develop and assess the psychometric properties of a Self-care Behaviors Scale (SCBS) among patients with RA.

Methods

In 2017, applying a cross-sectional design, we recruited a convenient sample of 436 RA patients in Hamadan, Iran, to participate in the study. We developed the initial scale, including 30 items, after literature review, and having recommendations from an expert panel. Face, content, construct and convergent validity, as well as reliability of the scale were investigated.

Results

In Exploratory Factor Analysis, the optimal solution comprising 25 items and 7 factors was emerged, which explained 62.5% of all variances between the items. In Confirmatory Factor Analysis, the measurement model fit the data well, and all subscales were significant within an acceptable range (χ2 [233] = 428.654, p < 0.0001, comparative fit index = 0.942, normed fit index =0.907, Tucker-Lewis index =0.916, and root mean square error of approximation = 0.043[(0.037-0.05]).

Conclusion

The Self-care Behaviors Scale was found with appropriate validity, reliability, functionality and simplicity. To our knowledge, this scale is the only valid and reliable RA specific self-care behavior scale in the literature. Healthcare providers and health practitioners may apply the English version of this suitable instrument to find more valid and reliable data on RA self-care behaviors during primary assessments of the behaviors in educational interventions for the patients.

Project description:BackgroundRheumatoid arthritis (RA) knowledge has been constructed with studies performed in Caucasians patients; Latin American patients present unique characteristics. Empowerment is a social multidimensional construct that has been associated to better health-related quality of life in RA. There is no validated instrument for use with Spanish-speaking patients. The objective of the study was to adapt the Spanish version of the Health Empowerment Scale (S-HES), which was selected for its psychometric properties and suitability for low-literacy populations, for RA Hispanic patients (RAEH), and to perform its psychometric validation.MethodsRAEH adaptation, pilot testing, and psychometric validation were performed. Three convenience samples of RA outpatients from a national tertiary care level center were used. For RAEH adaptation, the word "health" was substituted with "RA" in the original S-HES, integrated by 8 items. Pilot testing (in 50 patients) assessed feasibility. Psychometric validation included content validity (nine experts rated item convenience, clarity, and cultural semantic accuracy), internal consistency (in 200 patients, Cronbach's alpha) and test-retest (in a subsample of 50 patients, ICC and 95% CI), construct validity (factor analysis), and face validity (in 20 patients, % of agreement). Patients gave written informed consent.ResultsPatients were primarily middle-aged females and had typical long-standing disease, although early disease was represented. In the psychometric validation sample, the majority of the outpatients had autoantibodies; meanwhile, half of them had no evidence of disease activity, with acute reactants phase determinations within normal range. Patients with comorbidities and joint replacement were also included. Experts agreed upon the attributes of content validity: 83-100% considered the item was essential, 100% agreed on the item's clarity and 80-100% on the cultural semantic accuracy. In the pilot sample, ≥ 80% of the patients agreed with the item's clarity and format. In the psychometric validation sample, mean RAEH was 34 (maximum possible score: 40 = highest score). RAEH had a good internal consistency, Cronbach's α = 0.86, and moderately good reliability (ICC [95% CI] test-retest: 0.79 [0.62-0.88]). Factor analysis for construct validity showed a single factor explaining 52% of the variance. Patients agreed with each item content validity (85-100%) and clarity (75-100%).ConclusionsRAEH was valid and reliable to evaluate empowerment in Spanish-speaking RA patients.
