When solidarity hurts: (Intra)cultural trust, cultural betrayal sexual trauma, and PTSD in culturally diverse minoritized youth transitioning to adulthood.

Sexual trauma is associated with PTSD, with perpetrators putting women and girls more at risk than men and boys. Young adulthood is a time where risk of victimization and susceptibility to mental health problems increase. Certain contributors of costly trauma outcomes may be affected by the larger context of societal inequality. Cultural betrayal trauma theory (CBTT) highlights cultural betrayal in within-group trauma in minoritized populations as a dimension of harm that affects outcomes. In CBTT, within-group trauma violates the (intra)cultural trust-solidarity, love, loyalty, connection, responsibility-that is developed between group members to buffer against societal inequality. This violation, termed a cultural betrayal, can contribute to poorer mental health. The purpose of the current study is to address a gap in the CBTT literature by examining the role of (intra)cultural trust on the association between cultural betrayal sexual trauma and symptoms of PTSD among diverse minoritized youth transitioning to adulthood. Participants ( = 173) were diverse minoritized college students, who completed a 30-min online questionnaire at a location of their own choosing. Participants received course credit and could decline to answer any question without penalty. The results reveal that the interaction between cultural betrayal sexual trauma and (intra)cultural trust predicted clinically significant symptoms of PTSD. These findings have implications for increased cultural and contextual specificity in trauma research in minoritized populations, which can aid in the development and implementation of culturally competent interventions for diverse minoritized youth survivors of sexual trauma.
