    Associations of subjective and objective stress responses with interpersonal trauma, PTSD, stress-induced drinking, and drinking to cope in young adults
    (American Psychological Association, 2021) Danielson, Carla Kmett; Hahn, Austin M.; Bountress, Kaitlin E.; Adams, Zachary W.; Calhoun, Casey; Amstadter, Ananda B.; Thomas, Suzanne; Psychiatry, School of Medicine
    Objective: To understand how interpersonal trauma (IPT), stress response, and drinking to cope converge to predict stress-induced drinking, a risk factor for alcohol use disorder. Method: Young adults with no substance use disorder were classified into three trauma history groups: (a) IPT with PTSD (n = 27), (b) IPT without PTSD (n = 35), and (c) Control (no trauma-history/no PTSD; n = 36). Participants completed a baseline assessment, including a structured clinical interview, to confirm PTSD diagnosis, followed by the Trier Social Stressor Task (TSST) and an alcohol use task. Subjective units of distress and blood serum cortisol were collected at standardized timepoints throughout the tasks. Results: In all three groups (PTSD, IPT, control), males consumed more alcohol in the lab than females. Participants in the PTSD group had significantly higher drinking to cope motives, which were associated with greater subjective reactivity; however, neither drinking to cope motives nor subjective reactivity to the TSST predicted post-stressor alcohol consumption for those with PTSD. Conclusions: The interplay among trauma history, stress, and drinking among young adults is nuanced; additional lab-based studies are needed to further clarify the nuanced connection between trauma history, acute stress reactions, and alcohol use.

    Depressive symptoms, avoidant coping, and alcohol use: differences based on gender and posttraumatic stress disorder in emerging adults
    (Springer, 2024) Danielson, Carla Kmett; Hahn, Austin M.; Bountress, Kaitlin E.; Gilmore, Amanda K.; Roos, Lydia; Adams, Zachary W.; Kirby, Charli M.; Amstadter, Ananda B.; Psychiatry, School of Medicine
    Trauma exposure and alcohol use often co-occur. Unveiling predictors of drinking behavior, including among those with varying levels of trauma exposure, can inform behavioral health prevention and treatment efforts in at-risk populations. The current study examined associations between depressive symptoms, avoidant coping, gender, and alcohol use among emerging adults with and without trauma exposure and posttraumatic stress disorder (PTSD). Participants were 238 emerging adults between the ages of 21 and 30 years (M = 24.75; SD = 2.61) in one of three groups: trauma-exposed with PTSD (n = 70); trauma-exposed with no PTSD (n = 83); or a no trauma (control) group (n = 85). Demographics, parental alcohol problems, depressive symptoms, and avoidant coping were examined as predictors of drinks per drinking day. Chi-square, t-test, bivariate, and group path analysis were conducted. Among participants, men consumed greater amounts of alcohol than women across all three groups. Group assignment based on trauma history and PTSD significantly moderated the association between avoidant coping and alcohol use such that avoidant coping had a significant effect on alcohol use among participants in the trauma-exposed and PTSD groups. There was also a significant group × gender × avoidant coping interaction such that, among participants in the control group, men had attenuated alcohol use at low levels of avoidant coping and increased at high levels of avoidant coping. No effects of race were observed. Results highlight the importance of avoidant coping as a risk factor for problematic drinking, unveiling a specific intervention target for reducing co-occurring PTSD and problematic alcohol use.

    Predictors of Substance Use in a Clinical Sample of Youth Seeking Treatment for Trauma-Related Mental Health Problems
    (Elsevier, 2021) Adams, Zachary W.; Hahn, Austin M.; McCart, Michael R.; Chapman, Jason E.; Sheidow, Ashli J.; Walker, Jesse; de Arellano, Michael; Kmett Danielson, Carla; Psychiatry, School of Medicine
    Child maltreatment and traumatic events are well established risk factors for adolescent substance use problems, but little is known about the unique contributions of etiological factors on trauma-exposed youths' pre-treatment substance use in clinical settings. This study examined associations between substance use and risk and protective factors measured across multiple ecological levels among a unique sample of youth seeking treatment for trauma-related mental health problems in child advocacy centers. Participants were adolescents (N = 135; 85% female; 60% white, 31% black) aged 13-17 years (M = 15.4) with ≥ 1 experience of child maltreatment or other interpersonal violence, current substance use, and ≥5 PTSD symptoms. Youth and caregivers completed validated questionnaires and clinical interviews at a pre-treatment assessment in a randomized controlled trial of a treatment for co-occurring traumatic stress and substance use. Negative binomial regression models identified different patterns of risk and protective factors for alcohol and cannabis. Clinical implications of these results are discussed, including the potential targets for integrated psychotherapies that address co-occurring substance use and traumatic stress in youth.

    Risk reduction through family therapy (RRFT): Protocol of a randomized controlled efficacy trial of an integrative treatment for co-occurring substance use problems and posttraumatic stress disorder symptoms in adolescents who have experienced interpersonal violence and other traumatic events
    (Elsevier, 2020) Hahn, Austin M.; Adams, Zachary W.; Chapman, Jason; McCart, Michael R.; Sheidow, Ashli J.; de Arellano, Michael A.; Danielson, Carla Kmett; Psychiatry, School of Medicine
    Decades of research demonstrate that childhood exposure to traumatic events, particularly interpersonal violence experiences (IPV; sexual abuse, physical abuse, witnessing violence), increases risk for negative behavioral and emotional outcomes, including substance use problems (SUP) and posttraumatic stress disorder (PTSD). Despite this well-established link—including empirical support for shared etiological and functional connections between SUP and PTSD –the field has been void of a gold standard treatment for adolescent populations. To address this gap, our team recently completed a large randomized controlled trial to evaluate the efficacy of Risk Reduction through Family Therapy (RRFT), an integrative and exposure-based risk-reduction and treatment approach for adolescents who have experienced IPV and other traumatic events. The purpose of this paper is to provide a detailed description of the design and methods of this RCT designed to reduce SUP, PTSD symptoms, and related risk behaviors, with outcomes measured from pre-treatment through 18 months post-entry. Specifically, the recruitment and sampling procedures, assessment measures and methods, description of the intervention, and planned statistical approaches to evaluating the full range of outcomes are detailed. Clinical and research implications of this work are also discussed.

    Sexual Risk Behavior among Adolescents Seeking Treatment for Posttraumatic Stress Disorder: Exploring Psychosocial & Symptom Correlates
    (Springer, 2021-08-11) Banks, Devin E.; Hahn, Austin M.; Goodrum, Nada M.; Bernard, Donte L.; Adams, Zachary W.; McCart, Michael R.; Chapman, Jason; Sheidow, Ashli J.; de Arellano, Michael A.; Kmett Danielson, Carla; Psychiatry, School of Medicine
    Adolescents exposed to trauma experience disproportionate rates of HIV/STI. However, integrated treatment for trauma and sexual risk behavior is rare. To inform integrated prevention efforts, the current study describes prevalence and correlates of sexual risk behavior among adolescents seeking treatment for symptoms of posttraumatic stress and substance use disorders. Adolescents aged 13–18 years (N = 135; 88% female) with histories of interpersonal violence exposure completed pre-treatment questionnaires in a randomized controlled trial of an integrated psychotherapy for trauma and substance use symptomology. Adolescents reported high rates of sexual risk behaviors relative to national estimates and general mental health treatment samples. Symptoms of reexperiencing, substance use, and peer deviance were related to sexual risk behavior beyond the influence of other trauma symptoms. Individual and contextual psychosocial factors may be stronger predictors of sexual risk behavior than posttraumatic stress disorder symptoms among adolescents with trauma symptomology. Integrated interventions targeting traumatic stress, substance use, and sexual risk behavior concurrently may prevent revictimization and HIV/STI incidence among trauma-exposed youth.
