Abstract
Introduction: The health care system should provide qualified health care services to people with disabilities equal to other members of population. The attitude of health professionals in providing standard services to people with disabilities has a significant impact on the quality of health care services. This study aimed to translate the “Scale of Attitudes toward Disabled Persons” (SADP) to Persian, and evaluate its content validity and reliability.Materials and Methods: Initially, based on the International Quality of Life Assessment project the process of translating to Persian was done by 6 translators. Content validity ratio (CVR) and content validity index (CVI) were assessed by 8 occupational therapists. Relative content validity coefficient was investigated in order to verify the reliability of the questionnaire. The questionnaires were completed twice within 10 days by 52 health professionals who participated in this study. Internal consistency and the reliability of the test-retest were determined by calculating the Cronbach’s alpha coefficient and the intra-class correlation coefficient (ICC), respectively.Results: From 24 items, the presence of 22 items in the questionnaire was confirmed by calculating the CVR and CVI. The Cronbach's alpha for two subscales of optimism/human right and pessimism/behavior was 0.70 and 0.65, respectively. Intra-class correlation coefficient for the two scales was 0.71 and 0.69, respectively.Conclusion: The Persian version of SAPD has good content validity and internal consistency for evaluation the attitude toward people with disabilities. Test-retest reliability is average due to the nature of attitude evaluation. SADP, along with other tools, can be an appropriate tool for evaluation attitude of health professionals toward persons with disability.
