Results Item-level content validity index ranged from 0.800 to 1.000, and the scale-level content validity index was 0.952. Item analysis suggested each item distinguished well. Exploratory factor analysis identified 5 factors and explained for 62.550%of the variances. The Cronbach Alpha coefficients of subscales ranged from 0.424 to 0.932, and the total coefficient was 0.860. The test-retest reliability ranged from 0.799 to 0.957, and the total reliability was 0.925.
