다국어 초록 (Multilingual Abstract)

This study examined whether maladaptive cognitive emotion regulation strategies of unmarried adults in their 20s mediate the relationship between borderline personality disorder tendencies and relationship addiction, and whether self-differentiation moderates the mediating effect of maladaptive cognitive emotion regulation strategies. To this end, an online survey was conducted using the Borderline Personality Disorder, Relationship Addiction, Maladaptive Cognitive Emotion Regulation Strategy, and Self-Differentiation Scales targeting unmarried adults in their 20s, and the collected 331 copies were analyzed using SPSS 28.0 and PROCESS MACRO 4.1. The results of the study showed that, first, borderline personality disorder tendencies had a positive effect on relationship addiction. Second, maladaptive cognitive emotion regulation strategies partially mediated the relationship between borderline personality disorder tendencies and relationship addiction. Third, self-differentiation partially significantly moderated the relationship between borderline personality disorder tendencies and maladaptive cognitive emotion regulation strategies. Finally, the moderated mediating effect of self-differentiation through maladaptive cognitive emotion regulation strategy in the relationship between borderline personality disorder tendency and relationship addiction was partially significant. The research results confirmed that in a situation where borderline personality disorder tendency affects relationship addiction through maladaptive cognitive emotion regulation strategy, the intervention of self-differentiation alleviates the indirect effect of maladaptive cognitive emotion regulation strategy, thereby lowering the level of relationship addiction. In other words, it was found that self-differentiation plays an important protective factor in lowering the mediating effect of borderline personality disorder tendency leading to relationship addiction through maladaptive cognitive emotion regulation strategy. This study is meaningful in that it identified the factors and pathways that borderline personality disorder tendency affects relationship addiction in unmarried adults in their 20s, and presented the basis for establishing intervention methods in counseling settings to help prevent and alleviate relationship addiction.
