The Validity and Reliability of the Occupational Performance Questionnaire.

Purpose: In this study, it was aimed to examine the validity and reliability of the Turkish version of the Occupational Performance Questionnaire (OPQ) in individuals aged 3-6 with autism spectrum disorder. Material and Methods: After the questionnaire was translated into Turkish, it was applied to 51 parents with a child diagnosed with autism spectrum disorder aged 3-6 years. Cronbach Alpha coefficient was used to determine reliability. Correlation analysis with identical forms was used to establish the construct validity. In this context, correlation status of Occupational Performance Questionnaire with Sensory Profile Questionnaire and Parental Stress Index-Short Form were evaluated. Results: The Cronbach Alpha value for the Occupational Performance Questionnaire was found to be highly reliable as "0.93". In the correlation analysis between the main sections and sub-sections of the Occupational Performance Questionnaire and identical forms; significant correlation was found with all of the main sections, and sub-sections were found to have significant relationships other than "sleep, peer and group interaction, individual and group play" sections. Conclusion: The Occupational Performance Questionnaire is valid and reliable for Turkish children diagnosed with autism spectrum disorder aged 3-6. [ABSTRACT FROM AUTHOR]
