Objectives: Interpersonal trauma has deleterious effects on mental health, with college students experiencing relatively high rates of lifetime trauma. Asian American/Pacific Islanders (AAPIs) have the lowest rate of mental healthcare utilization. According to cultural betrayal trauma theory, societal inequality may impact within-group violence in minority populations, thus having implications for mental health. In the current exploratory study, between-group (interracial) and within-group (ethno-cultural betrayal) trauma and mental health outcomes were examined in AAPI college students. Participants: Participants (N = 108) were AAPI college students from a predominantly white university. Data collection concluded in December 2015. Methods: Participants completed online self-report measures. Results: A multivariate analysis of variance revealed that when controlling for interracial trauma, ethno-cultural betrayal trauma significantly impacted dissociation, hallucinations, posttraumatic stress symptoms, and hypervigilance. Conclusions: The results have implications for incorporating identity, discrimination, and ethno-cultural betrayal trauma victimization into assessments and case conceptualizations in therapy.
