Background: Evaluation of prosthesis and orthosis (P&O) devices and service satisfaction in patients using P&O are important to understand the patient perspective and improve the quality of devices and the services.Objective: The aim of this study was to translate the original Orthotics and Prosthetics Users' Survey (OPUS) satisfaction module into Turkish and examine its psychometric properties in lower limb P&O users. Study Design: Cross-sectional study. Methods: The Turkish versions of the OPUS-Client Satisfaction with Device (CSD) and Service (CSS) modules were applied to 157 individuals using a lower limb prosthesis or orthosis. The retest of the survey was applied 5-7 days later. Intraclass correlation coefficient was used to determine test-retest reliability, and Cronbach alpha was used to determine internal consistency. Criterion validity was evaluated using the Nottingham Health Profile. Exploratory factor analysis was used to examine the factor structure of the Turkish version of the OPUS satisfaction module. Results: The test-retest correlation (intraclass correlation coefficient 5 0.92 for CSD and 0.91 for CSS) and internal consistency (Cronbach's alpha 5 0.84 for CSD and 0.95 for CSS) were high. A statistically significant correlation was found between the OPUS CSD and CSS modules and the Nottingham Health Profile (r 5 20.325 for CSD module, r 5 20.381 for CSS module, P , 0.001). The factor analysis revealed one-factor structure for both modules.Conclusions: This study demonstrated the reliability and validity of the Turkish version of the OPUS satisfaction module, and it provides a useful starting point for future studies on this survey.

Background/aim The aim of this study is to assess the validity and reliability of Turkish translation of the Physical Activity Scale for Individuals with Physical Disabilities (PASIPD) in a disabled Turkish population. Materials and methods Following the translation protocol of the PASIPD, the Turkish version of the PASIPD, Short Form-36, and International Physical Activity Questionnaire were administered to 198 developmentally and physically disabled individuals. Results The Turkish version of the PASIPD was found to be reliable. The domains of the Turkish version of the PASIPD were also found to be valid. Four factors were obtained from the questionnaire. The ICC was 1.0 since all the respondents reported the same answers in the test and retest. The Cronbach α for the PASIPD was 0.60. Conclusion The Turkish version of the PASIPD survey is valid and reliable for developmentally and physically disabled Turkish individuals and professionals can use it to assess physical activity level.
