... seven domestic violence experience items as determinants of cluster membership. Results: In the ACOA cohort, four clusters were identified by childhood domestic violence experience-Low Violence, Witness, Emotional Violence, and Multiple Violence. Only two clusters were found among non-ACOAs-None versus Multiple Violence. All adult mental health and family health characteristics were significantly different between these six empirically-derived clusters. The ACOAs in the Emotional Violence group showed the lowest resilience and sense of belonging, and highest depression scores, which were significantly different from each corresponding score of the ACOAs in the Witness group. ACOAs who experienced multiple violence showed lowest level of family health among the six clusters. Conclusion: The findings indicate that ACOAs and non-ACOAs may have very different patterns of childhood domestic violence, which are associated with distinct psychological entities in adulthood.
