<p>Emerging adulthood is a critical period for the onset of depression and anxiety. Family coping patterns may shape young adults’ coping and psychological symptoms, providing an important target for early mental health interventions. This study examined the transgenerational transmission of dysfunctional and adaptive coping among Turkish young adults and their parents. Young adults (<i>N</i> = 371, <i>M</i>_<i>age</i>=21.22) completed a demographic form, the DBT Ways of Coping Checklist, and the Brief Symptom Inventory; parents completed the DBT Ways of Coping Checklist. Young adults’ dysfunctional coping positively predicted depression and anxiety, whereas adaptive coping negatively predicted depression but not anxiety. Maternal adaptive coping predicted young adults’ adaptive coping and indirectly their depression. Both parents’ dysfunctional coping predicted young adults’ dysfunctional coping and indirectly their symptoms. Findings highlight distinct maternal and paternal contributions to coping socialization and underscore the value of DBT-informed, family-based interventions to reduce depression and anxiety in emerging adulthood.</p>
