Abstract:

Aim: The aim of the study was to examine the validity and reliability of the Turkish version of the Hospital for Special Surgery Knee Replacement Expectations Survey. Method: One hundred four participants (Female: 81/Male: 23) with total knee arthroplasty indications were included in the study. The survey assessing the expectations of the patients from knee replacement surgery consists of 19 items. The factor analysis method was used to evaluate construct validity. The Visual Analogue Scale (VAS) was used to calculate concurrent validity, which is another measurement method in which patients specify their expectation levels. The reliability of the survey was evaluated by using test-retest, item analysis, and internal consistency Cronbach's alpha coefficient. Results: The mean age of the participants was 60.25±9.72 years. The sample adequacy index was 0.884. As a result of the factor analysis, it was found that 65.95% of the total variance was explained, and it was unidimensional as in the original form of the questionnaire. The Turkish version of the questionnaire was found to be perfectly reliable regarding the internal consistency coefficient (Cronbach's alpha=0.929). A significant correlation was found between test-retest analysis results (r=0.564; p=0.002). According to the concurrent validity results, a significant relationship was found between the questionnaire and the VAS (r=0.446; p<0.001). Conclusion: The Turkish version of the Hospital for Special Surgery Knee Replacement Expectations Survey is a valid, reliable, and easily applicable assessment tool with 19 items.
