<![CDATA[This study aims to evaluate the effectiveness of Dialectical Behavior Therapy (DBT) in improving emotional regulation skills and reducing self-harm behaviors among university students aged 18–25 with a history of family relationship issues and tendencies toward self-harm. Using a one-group before-and-after experimental design, five participants underwent six DBT intervention sessions, encompassing phases of introduction, problem identification, and emotional regulation strategies. Research instruments included the Self-Harm Inventory (SHI), Emotion Regulation Questionnaire (ERQ), as well as graphic tests, observation, and interviews. Results showed a significant improvement in the cognitive reappraisal aspect and a reduction in expressive suppression in the ERQ, indicating adaptive emotional regulation skill enhancement. Additionally, self-harm scores on the SHI decreased for most participants. Qualitative data also supported these findings, with participants beginning to apply positive strategies such as exercising and socializing with close friends. In conclusion, DBT is effective in helping individuals with self-harm tendencies improve emotional regulation and reduce maladaptive behaviors.
