Abstract
OBJECTIVE
Stress management delays the onset or exacerbation of symptoms of multiple sclerosis. The present study aimed to develop and psychometrically evaluate a questionnaire to measure the determinants of stress coping behaviors in patients with multiple sclerosis.
METHODS
This was a methodological study that was conducted in two stages: qualitative and quantitative phases. Participants in this study were patients with multiple sclerosis who referred to the MS Association and Charity Foundations for Special Diseases in Isfahan in 2021. Preliminary item pool was developed by qualitative part of the study. The validity of the questionnaire was determined with item impact, content validity ratio (CVR), content validity index (CVI), face validity, exploratory factor analysis (EFA) and confirmatory factor analysis (CFA).
RESULTS
In the first stage, an item pool containing 97 items were generated and after removing duplicate items and merging some of them, a questionnaire containing 51 items was developed. Ten items were removed based on the results of face validity and content validity. The EFA revealed 11 factors containing 41 items that explained 64% of the total variance of test. In CFA, 9 other items were deleted, and the questionnaire was reduced to 32 phrases in general. The results of the CFA determined the 9-factor structure of the questionnaire including awareness, attitude, self-efficacy, access to resources, skills of using resources, social support, important others, behavioral consequences and social comparison. The Cronbach's alpha coefficient of the questionnaire was 0.726.
CONCLUSION
The results showed that the designed questionnaire is a valid and reliable tool for assessing the determinants of stress coping behaviors in patients with multiple sclerosis. Identifying these factors and designing interventions based on them, in order to control or reduce stress in these patients, can help to improve the quality of life in these patients.
