Abstract

Background: Access to rehabilitation services is considered to be a right for all people. One of the most important indicators for access to rehabilitation services is an individual’s general acceptance of rehabilitation. This tool was designed based on relevant studies and experiences of rehabilitation specialists to design a questionnaire to specifically measure patient acceptability of physical rehabilitation services. Methods: In this study, an exploratory sequential mixed methods design was used. The first phase included a review of the literature and analysis of relevant studies, focus group discussions, and qualitative content analysis. In the second phase, construct validity was assessed by exploratory and confirmatory factor analysis. Also, convergent and divergent validity were measured. Reliability was evaluated by internal consistency (Cronbach's alpha and McDonald's Omega) and construct reliability. Statistical procedures were calculated by SPSS-AMOS24 and JASP0.9.2 software. Results: A total of 200 questionnaires were completed by members of Iranian Disability Campaign. Three factors and 25 items were identified according to results of the first phase of this study. In the second phase, face validity was confirmed. To assess the content validity ratio, 9 items, with the mean of content validity ratio (CVR) < 0.49, were deleted, while the content validity index (CVI) < 0.79 was revised. The kappa coefficient < 0.6 was fair and scale content validity index (SCVI) under 0.9 was considered appropriate. Results of exploratory factor analysis showed that 48% of the variance of the acceptability of physical rehabilitation services was based on patients’ satisfaction, ethical behavior, and patient centered services. Confirmatory factor analysis confirmed the suitability of the final model. Convergent and divergent validity and reliability of the measure, the Physical Rehabilitation Services Acceptability questionnaire was fulfilled. Conclusion: Findings indicated that the proposed constructs that promoted the Acceptability of Physical Rehabilitation Services Questionnaire had good validity and reliability in participants with physical disabilities.
