Initial Psychometric Evaluation of the Social Safeness and Pleasure Scale Japanese Version

This study conducted an initial psychometric evaluation of the Japanese version of the Social Safeness and Pleasure Scale (SSPS-J). In Study 1 (N = 477), exploratory factor analysis supported a single-factor structure with excellent internal consistency (alpha = 0.95, omega = 0.95). Significant correlations with depression (r = −0.53), anxiety (r = −0.26), stress (r = −0.36), life satisfaction (r = 0.67), and social support (r = 0.47–0.52) demonstrated robust convergent validity. In Study 2, confirmatory factor analysis (N = 262) confirmed the reproducibility of the single-factor model with an acceptable overall fit (CFI = 0.943, SRMR = 0.036, RMSEA = 0.108). Test–retest reliability over a three-week interval (N = 113) was also high (ICC = 0.88). These results suggest that the SSPS-J is a reliable and valid preliminary measure for assessing social safeness in the Japanese general population.
