Development and Validation of the Acculturation Discrepancy Scale for Youth of Korean Descent in Japan（ADS-KJ）

Abstract 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 Korean 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 Japan’s Korean immigrant families. Thus, it can guide and support Korean descent youth in Japan’s growing immigrant society.
