Objective:Early life adversity is strongly correlated with a number of negative health outcomes, with some of the highest risks are related to later illicit drug use and substance use disorders (SUDs). Specifically, it has been found that an ACEs score of >4 confers a 7-10-fold risk of substance abuse. Subsequent research has identified a number of neurobiological effects of childhood trauma, including structural and functional disruptions of the LHPA axis, the brain's primary stress-response system. It has been hypothesized that various trauma-induced neurobiological changes may lead to later physical health, mental health, and psychosocial problems in persons with early life adversity. One area that such changes might affect is a person's ability to stop abusing substances, with factors such as trauma-related mood, self-efficacy, or cognitive functioning as considerations in early treatment success. This study followed a group of participants in a residential substance abuse treatment program across their first month of abstinence, to assess natural change in cognitive performance as well as potential effect of early life adversity on changes in neuropsychiatric outcomes.Participants and Methods:Participants were 37 adults (mean age=33.9 years, SD=6.7) who had completed detoxification and were first assessed during their first week of residential treatment. Follow-up assessment was completed 4 weeks later. Participants were primarily male (62%) and white (62%). They were all in treatment for opioid abuse, with a majority of participants reporting a history of polysubstance abuse. To measure adverse and protective factors, participants completed the Adverse Childhood Experiences scale and Protective And Compensatory Experiences Scale at baseline. Participants also completed the NIH Toolbox cognition battery and a set of self-report measures of cognitive functioning, mood, anxiety, and self-efficacy at baseline and follow up.Results:Results of paired samples t-test comparison between baseline and follow-up testing found a significant improvement in self-reported depression symptoms, anxiety symptoms, and self-efficacy (all p<.001). Interestingly, participants overall reported an increase in cognitive problems between baseline and retest, even though on objective cognitive testing (NIH Toolbox cognition battery) there was significant improvement in cognitive performance. Participants generally had a high level of childhood adversity (mean ACE score of 4.5), with an average level of childhood compensatory experiences. Considering the specific effect for childhood adversity, ACE score was found to be predictive in amount of anxiety and self-reported cognitive change but not for objective cognitive performance or change in other factors.Conclusions:Consistent with previous research, these patients had a high level of past trauma, which interacted with a number of other neuropsychiatric measures and support the importance of assessing for trauma history and integrating trauma-focused treatment into substance abuse treatment programs.
