Evaluation of validity and reliability of Persian version of Constant Murley Score questionnaire
Shoulder pain is a common musculoskeletal disorder in the general public. Shoulder impingment syndrome is one of the most common shoulder disorders. Due to the lack of a similar questionnaire in Iran and the need to use standard tools in the field of clinical evaluation, localization and validity and reliability of the Persian version of this questionnaire was considered as the purpose of this study.
This study included 20 women with shoulder involvement syndrome in the age range (20-50) years who were evaluated by a physiotherapist.Using the translation-re-translation method, the necessary corrections were made and the final form of the questionnaire was prepared. In order to determine the content validity of CVI and CVR methods, to determine the degree of reliability, internal consistency test (Cronbach's alpha) was used and to evaluate the reliability, test-retest.
The results of CVI showed that all questions with CVI score higher than 0.79, patient ward (0.85 on communication scale, resolution 1, simplicity 0.92, ambiguity 0.92) and physician ward (on communication scale 1, resolution 1, Simplicity 1, Ambiguity 0.88). average content validity index of the patient ward was 0.92 and the physician ward was 0.97. Statistical analysis showed that the internal consistency of the Cronbach's alpha questionnaire questions is equal to 0.74. ICC values showed that the intra-group correlation of the patient ward (% 95 CI: 96-89) and the physician ward (95% CI: 95 -88) were calculated.
