The experiences of historical and cultural traumas such as chronic poverty, instability, and violence have insidious and long-lasting effects up to three generations from survivors through genetic or learned transmission (Bezo & Maggi, 2015; Bradfield, 2013; Connolly 2011;Forrest-Perkins 2017). Although there has been a movement towards recognizing such traumas and their effects in psychological literature, there still remains a dearth in examination for Asian/Asian Americans and specific ethnic groups such as Korean/Korean Americans (Cai & Lee, 2022; Kim-Martin, 2021). Thus, a critical interpretive synthesis (CIS) was utilized to synthesize the current literature on AAA historical/cultural traumas and examine their effects on survivors, their descendants, and family functioning. Further, a randomized control trial study design was conducted to utilize psychoeducation with a group of Koreans/Korean Americans to examine whether learning about historical/cultural traumas shifted perceptions of family functioning and family communication. The groups included in the trial includes the psychoeducation intervention group and a control group that received psychoeducation on a non-trauma related topic, with the aims of exploring collective healing for the Korean/Korean American community.
