Psychometric Examination of the Japanese Version of the Emotion Beliefs Questionnaire¹²³⁴

Emotion beliefs include beliefs regarding usefulness and controllability of emotions, and they play an important role in emotion regulation. This study developed a Japanese version of the Emotion Beliefs Questionnaire (EBQ-J) and examined its reliability and validity. A total of 317 participants were surveyed (212 women, 98 men, 7 not indicated; mean age: 20.06 ± 2.84 years). A preliminary survey was conducted with 23 undergraduate students to develop a draft of the Japanese version. The results confirmed the face validity of the measurement. The first cross-sectional survey examined descriptive statistics, structural validity, internal consistency, construct validity, and gender differences in measurement scores. The second, short-term longitudinal and cross-sectional survey evaluated the test–retest reliability and construct validity. Confirmatory factor analysis indicated that the EBQ-J had a four-first-order-factor and two-second-order-factor structure. The results were consistent with the original EBQ. The measurement demonstrated good internal consistency, moderate to excellent test–retest reliability, and partially verified construct validity. The EBQ-J could assess emotion beliefs across positive and negative emotions and explain emotion regulation processes.
