Our study was a methodological one and was designed as a validity and reliability study. Our study included factor analyses for validity analysis, Cronbach alpha, item-total correlation, test-retest correlation analysis for reliability analysis. In our study, statistical significance was considered as p < 0.05 and SPSS statistical package program was employed for calculations.

Results: In our study, Kaiser-Meyer-Olkin's value was 0.86, and Bartlett's result was p < 0.05. Cronbach alpha was found as 0.86. The correlation analysis of test-retest points was 0.975 (97.5%) with a p-value 0.000, there was a significant difference.
