Brief summary: Wheelchair users frequently experience shoulder pain. It has been determined that in our country, the subjective assessment methods that will help to determine and monitor shoulder pain severity of wheelchair users are limited. The purpose of this study is to adapt the original English version of the Wheelchair Users Shoulder Pain Index into Turkish and to assess its validity and reliability.

Firstly, the original English version of WUSPI was translated into Turkish and culturally adapted, then applied to 100 wheelchair users to investigate the validity of the scale. The reliability of the scale was assessed by internal consistency and test-retest analysis and found a high internal consistency. Validation of WUSPI-Tr was assessed by the concurrent validity method. To establish concurrent validity, WUSPI scores were compared to SPADI and ASES scores by Spearman correlation analysis. There was a positively excellent correlation with SPADI and, negatively excellent correlation with ASES. As a result, it is determined tath the Turkish version of WUSPI-Tr is a valid and reliable tool.

Detailed description: The original version of WUSPI was translated into Turkish via multistep translation rules. It is culturally adapted into Turkish. The semantic equivalence of the new scale was evaluated and the Turkish version of the WUSPI (WUSPI-Tr) has been created. It is applied to 100 wheelchair users to investigate the validity of the scale. People who are at least for 1 year using a manual wheelchair as their primary means of mobility, cognitively unimpaired, literate, and older than 18 years are included in this study. The reliability of the scale was assessed by internal consistency and test-retest analysis. As a result of the analysis, the Cronbach Alfa value was calculated as 0.894, and WUSPI-Tr was found to have high internal consistency. The WUSPI-Tr questionnaire was re-administered to 50 participants for 7 to 14 days for the test-retest method and the results were compared with the Interclass Correlation Coefficient (ICC) method. WUSPI has been found to have high reliability (0.997). Validation of WUSPI-Tr was assessed by the concurrent validity method. To establish concurrent validity, WUSPI scores were compared to SPADI and ASES scores by Spearman correlation analysis. The correlation coefficient of WUSPI-Tr with SPADI is 0.931 and with ASES was -0.812. These results show that there was a positively excellent correlation with SPADI and, negatively excellent correlation with ASES (p \< 0,001). As a result, the Turkish version of WUSPI-Tr is a valid and reliable tool.
