Development and validation of the acculturation discrepancy scale for youth of Korean descent in Japan (ADS-KJ)

BACKGROUND: This study aimed to develop and validate the Acculturation Discrepancy Scale for Youth of Korean Descent in Japan (ADS-KJ). The scale measures youths’ subjective perceptions of intergenerational cultural gaps, that lead to parent–child acculturation discrepancies. METHODS: Based on interview data and a review of previous studies, an item pool was created and administered via questionnaire surveys to 278 youths of Korean descent in Japan and 110 Japanese youths. The scale’s structural validity, construct validity, internal consistency, test-retest reliability, and criterion-related validity were examined. RESULTS: Consequently, it was developed as a 21-item, two-factor scale comprising Identity Discrepancy and Values Discrepancy. ADS-KJ demonstrated generally good reliability and validity, though some areas relating to its criterion-related validity need further examination. CONCLUSION: As a culturally sensitive assessment tool, ADS-KJ shows potential to capture youths’ subjective perceptions of parent–child acculturation discrepancies in families of Korean descent in Japan. Thus, it can guide and support Korean descent youth in Japan’s growing immigrant society.
