[Cross cultural adaptation, validity and Reliability study of the Persian version of the American shoulder and elbow surgeons [ASES] questionnaire for evaluation of shoulder function in injured athletes]

ABSTRACT

The translation, cultural adaptation and validation of the Persian version of the American shoulder and elbow surgeons [ASES] were carried out in accordance with published guidelines. The study was conducted on 100 athletes [25.96 +/- 5.81 years], which suffered from different shoulder disorders. When the translation and cultural adaptation of the original questionnaire was carried out on the standardized method, the participants were asked to complete a questionnaire booklet including the DASH, the Short Form General Health Survey [SF-36] and ASES questionnaires. In addition, 30 randomly selected patients were asked to complete the ASES questionnaire 48 hours later for the second time. After data collection the Statistical analysis was performed by using SPSS software. The Cronbach's alpha was used to indicate internal consistency. Cronbach's alpha was 0.91 for ASES. Test-retest reliability was quantified by use of the intraclass correlation coefficient. It was 0.91 for ASES questionnaire. The Pearson Correlation Coefficient was used for the questionnaire validation study. The DASH questionnaire showed high correlation of ICC=0.78 with ASES. The ASES showed moderate correlation of 0.48 to 0.62 with those of the various scales of the SF-36. The Iranian ASES showed good reliability and validity and can be used for shoulder-specific patient self-assessment
