Korean immigrants are motivated to accept new cultural perspectives and/or transform their own cultural values into those of their new country. During this acculturation process, they encounter cultural differences, make adaptations, and thus may experience positive changes in social relationships, coping resources, personal strength, and cultural knowledge. The purpose of this study was to investigate the relationship between the dimensions of acculturation and personal growth. The results indicated that two dimensions of acculturation (e.g., self-control and collectivism), age, and length of stay were predictors of personal growth that involves social relationships, personal resources, life philosophy, and coping skills. This study suggests that high scores on two acculturation dimensions indicated lower acculturation, which predicts personal growth.
