ObjectiveThe purpose of the present study was to compare self-report and interview administration methods using the Western Ontario Rotator Cuff Index (WORC) and Disabilities of the Arm, Shoulder and Hand Questionnaire (DASH) in patients with rotator cuff disorders.MethodsThirty male and female patients over 18 years of age with rotator cuff disorders (tendinopathy or rotator cuff tear) and Brazilian Portuguese as their primary language were recruited for assessment via administration of the Western Ontario Rotator Cuff Index and and Disabilities of the Arm, Shoulder and Hand Questionnaire. A randomization method was used to determine whether the questionnaires would be self-reported (n=15) or administered by an interviewer (n=15). Pearson correlation coefficients were used to evaluate the correlation between the Western Ontario Rotator Cuff Index and and Disabilities of the Arm, Shoulder and Hand Questionnaire in each group. The t-test was used to determine whether the difference in mean questionnaire scores and administration time was statistically significant. For statistical analysis, the level of significance was set at 5%.ResultsThe mean subject age was 55.07 years, ranging from 27 to 74 years. Most patients had a diagnosis of tendinopathy (n=21). With regard to level of schooling, the majority (n=26) of subjects had completed a college degree or higher. The mean questionnaire scores and administration times did not significantly differ between the two groups (p>0.05). There were statistically significant correlations (p<0.05) between Western Ontario Rotator Cuff Index and and Disabilities of the Arm, Shoulder and Hand Questionnaire, and strong correlations were found between the questionnaires in both groups.ConclusionThere are no differences between the Western Ontario Rotator Cuff Index and Disabilities of the Arm, Shoulder and Hand Questionnaire administration methods with regard to administration time or correlations between the questionnaires.
