抄録

This study investigated the reliability and validity of the Japanese versions of the Fear of Happiness Scale and the Fragility of Happiness Scale. The scales were administered to 341 Japanese undergraduates. Confirmatory factor analysis showed that, like the original versions, the Japanese Fear of Happiness Scale and the Fragility of Happiness Scale each had a one-factor structure. The two scales also each had good internal consistency, test-retest reliability, and construct validity. Furthermore, the scales showed incremental validity by predicting psychological elements (life satisfaction, depression, anxiety, stress) better than the behavioral inhibition system (BIS) and the behavioral activation system (BAS). The results of the present study revealed that the Fear of Happiness Scale and the Fragility of Happiness Scale had an adequate reliability and validity in this Japanese group.
