Adverse childhood experiences and adulthood mental health: a cross‑ cultural examination among university students in seven countries

Abstract

While there is evidence that histories of adverse childhood experiences (ACEs) are common in university students and are associated with an increased risk of mental health difficulties, current research has limited geographic and cross-cultural representation. Comparing ACEs across diverse contexts using a standardized measure can illuminate geographic and sociocultural similarities or differences in exposure. The present study aimed to assess ACE exposure and its relationship withmental health symptoms in university students from seven countries. We sampled 5945 university students from the United States, Canada, England, South Africa, Spain, Argentina, and Uruguay. Participants completed the Adverse Childhood Experiences International Questionnaire (ACE-IQ) and the Inventory of Depression and Anxiety Symptoms (IDAS). Most participants (94.8%) reported exposure to at least one type of ACE and 61% reported exposure to four or more types. Repeatedexposure to at least one ACE was reported by 70.2% and repeated exposure to at least four ACEs was reported by 21.2%. Spanish students had significantly lower ACE exposure than other students. Cumulative ACE exposure was significantly higher among students in lower income countries, but when repeated exposure was considered these differences fell away. For the total sample, cumulative ACE exposure was significantly associated with severity of depression symptoms, anxiety symptoms, and suicidality. Findings indicate that universities globally should be guided by a trauma-informed approach that recognizes students as a psychologically vulnerable group carrying a long-standing burden of childhood adversity.
