The purpose of this study was to test the effectiveness of Acceptance Commitment Therapy ACT to improve posttraumatic growth in young adults who had experienced violence in dating. Conflict often appears in dating relationships in young adults. Inappropriate conflict resolution may result in violence. Until now the handling of cases of violence in dating in Indonesia has no legal basis, so the victims do not get the right handling and can cause mental health problems such as psychological trauma. Acceptance Commitment Therapy ACT . ACT has been shown to address the problem of psychological trauma, but has never been associated with posttraumatic growth. There were 7 participants who scored below the cutoff on each Posttraumatic Growth Inventory PTGI domain and scored above the depressive symptom of Global Health Questionnaire 12 GHQ 12 . Participants were divided into two groups, the experimental group will receive treatment in the form of intervention of 5 sessions of Acceptance Commitment Therapy ACT , while the control group will get intervention after the participant group finished. All experimental participants experienced an increase in PTGI scores and a decrease in GHQ 12 score. There was one experimental group participant who did not reach the cutoff score limit on the two PTGI domains, while all control group participants achieved the cutoff scores of PTGI and GHQ 12 scores. It should be considered to add acceptance sessions to further research.Keywords Acceptance Commitment Therapy Young Adult Dating Violence Posttraumatic Growth
