Results: content validity index ≥ 0.8 each item. For self informant versions, Cronbach’s α 0.753 0.807, respectively, while Spearman’s correlation coefficient 0.953 ( P < 0.001) 0.918 0.001). items demonstrated good communality (0.532–0.870), on rotation, 12 components had eigenvalues > 1, explained 72.3% total variance. estimate, AP, RP, PL subscales were 2.60 (sensitivity 0.825; specificity 0.575; odds ratio [OR] 6.38, 95% confidence interval [CI] 2.28–17.84; 0.001), 0.60; 0.75; OR 4.50, CI 1.73–11.70; 0.002), 2.90 0.8; 0.475; 3.62, 1.342–9.77; 0.011), 2.70 0.5; 4.71, 1.69–13.13; 0.003), respectively.
