The Turkish Version of the WUSPI
Condition: Shoulder Pain
MeSH terms: Shoulder Pain
Study type: Observational [Patient Registry]

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.
