Research has indicated the effectiveness of Dialectical behavior therapy in adolescents (DBT-A) with severe emotion dysregulation and other symptoms of Borderline Personality Disorder (BPD). The objective was to determine if DBT skills group with caregivers only could influence in potential mediators of DBT outcomes including rearing styles, emotion regulation and mindfulness skills, evaluated in both parents and adolescents. We implemented a 12-week group intervention based on DBT-A addressed to seven parents of adolescents with features of BPD. We tested differences after treatment using the non-parametric Wilcoxon test and calculated effect sizes. To understand individual changes, we reported clinical reliable change (CRC). The intervention was effective for improving rearing styles, emotion regulation and mindfulness skills in adolescents. Changes were stable after 6 months. The intervention showed good levels of satisfaction reported by parents. A short DBT group-only intervention with caregivers could modify relevant processes related with features of BPD in adolescents. Early interventions with adolescents with symptoms of BPD could prevent the development of BPD influencing in potential mediation mechanisms.
