Adolescent Substance Use Following A Deadly U.S. Tornado Outbreak: A Population-Based Study of 2,000 Families
(Taylor & Francis, 2017) Danielson, Carla Kmett; Sumner, Jennifer A.; Adams, Zachary W.; McCauley, Jenna L.; Carpenter, Matthew; Amstadter, Ananda B.; Ruggiero, Kenneth J.; Psychiatry, School of Medicine
Objective: Despite conceptual links between disaster exposure and substance use, few studies have examined prevalence and risk factors for adolescent substance use and abuse in large, population-based samples affected by a recent natural disaster. We addressed this gap using a novel address-based sampling methodology to interview adolescents and parents who were affected by the fourth deadliest tornado outbreak in U.S. history. Method: Post-disaster interviews were conducted with 2,000 adolescent-parent dyads living within a 5-mile radius of the Spring 2011 U.S. tornadoes. In addition to descriptive analyses to estimate prevalence, hierarchical linear and logistic regression analyses were used to examine a range of protective and risk factors for substance use and abuse. Results: Approximately 3% reported substance abuse since the tornado. Greater number of prior traumatic events and older age emerged as consistent risk factors across tobacco and alcohol use and substance abuse since the tornado. Tornado incident characteristics, namely greater loss of services and resources after the tornado and PTSD since the tornado, were associated with greater alcohol consumption. Service loss increased risk for binge drinking, whereas, for substance abuse, PTSD increased risk and parent presence during the tornado decreased risk. Greater family tornado exposure was associated with a greater number of cigarettes smoked in female but not male teen participants. Conclusions: Both trauma and non-trauma-related factors are relevant to post-disaster substance abuse among adolescents. Future research should examine the role of broader ecological systems in heightening or curtailing substance use risk for adolescents following disaster exposure.
Associations among Impulsivity, Trauma History, and Alcohol Misuse within a Young Adult Sample
(Elsevier, 2017) Bountress, Kaitlin E.; Adams, Zachary W.; Gilmore, Amanda K.; Amstadter, Ananda B.; Thomas, Suzanne; Danielson, Carla Kmett; Psychiatry, School of Medicine
Objective: Young adult alcohol misuse is associated with numerous long-term adverse outcomes. Given the link between impulsivity and alcohol use, we examined whether three impulsivity-related traits differentially predicted number of drinks per drinking day (DDD). We also examined whether these effects varied for those with different trauma histories. Method: The current study (n=254) examined motor, non-planning, and attentional impulsivity as predictors of DDD. It also examined whether impulsivity was differentially predictive of DDD across individuals in: a control group (non-trauma exposed), a trauma exposed but non-PTSD group, and a PTSD group. Results: Regardless of group, more motor impulsivity was associated with more DDD. The effect of non-planning impulsivity varied according to trauma history. Specifically, more non-planning impulsivity predicted more DDD for those without PTSD. Finally, attentional impulsivity was not predictive of DDD. Conclusions: Young adults with high levels of motor impulsivity, regardless of trauma history, may be a particularly high-risk group in terms of propensity for alcohol use/misuse. Additionally, high levels of non-planning impulsivity may signify those at greater risk for alcohol misuse, among those without PTSD. Motor impulsivity and non-planning impulsivity may serve as useful intervention targets in alcohol misuse prevention efforts. Implications for future research in this area are discussed.
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.
Clinical Decision Making Following Disasters: Efficient Identification of PTSD Risk in Adolescents
(Springer, 2017) Danielson, Carla Kmett; Cohen, Joseph; Adams, Zachary W.; Youngstrom, Eric A.; Soltis, Kathryn; Amstadter, Ananda B.; Ruggiero, Kenneth J.; Psychiatry, School of Medicine
The present study aimed to utilize a Receiver Operating Characteristic (ROC) approach in order to improve clinical decision-making for adolescents at risk for the development of psychopathology in the aftermath of a natural disaster. Specifically we assessed theoretically-driven individual, interpersonal, and event-related vulnerability factors to determine which indices were most accurate in forecasting PTSD. Furthermore, we aimed to translate these etiological findings by identifying clinical cut-off recommendations for relevant vulnerability factors. Our study consisted of structured phone-based clinical interviews with 2000 adolescent-parent dyads living within a 5-mile radius of tornados that devastated Joplin, MO, and northern Alabama in Spring 2011. Demographics, tornado incident characteristics, prior trauma, mental health, and family support and conflict were assessed. A subset of youth completed two behavioral assessment tasks online to assess distress tolerance and risk-taking behavior. ROC analyses indicated four variables that significantly improved PTSD diagnostic efficiency: Lifetime depression (AUC = .90), trauma history (AUC = .76), social support (AUC = .70), and family conflict (AUC = .72). Youth were 2-3 times more likely to have PTSD if they had elevated scores on any of these variables. Of note, event-related characteristics (e.g., property damage) were not related to PTSD diagnostic status. The present study adds to the literature by making specific recommendations for empirically-based, efficient disaster-related PTSD assessment for adolescents following a natural disaster. Implications for practice and future trauma-related developmental psychopathology research are discussed.
Clinician Perspectives on Treating Adolescents with Co-occurring Post-Traumatic Stress Disorder, Substance Use, and Other Problems
(Taylor & Francis, 2016) Adams, Zachary W.; McCauley, Jenna L.; Back, Sudie E.; Flanagan, Julianne C.; Hanson, Rochelle F.; Killeen, Therese K.; Danielson, Carla Kmett; Psychiatry, School of Medicine
Clinicians (n=138) who treat adolescents with co-occurring posttraumatic stress and substance use disorders (PTSD+SUD) were surveyed about their attitudes and practice behaviors. Most providers were trained in PTSD treatment; fewer were trained in SUD or PTSD+SUD treatments. PTSD+SUD treatment was rated more difficult than treatment of other diagnoses. Providers typically addressed symptoms of PTSD and SUD separately and sequentially, rather than with integrated approaches. There was no consensus about which clinical strategies to use with adolescent PTSD+SUD. Continued treatment development, training, and dissemination efforts are needed to equip providers with resources to deliver effective treatments to adolescents with PTSD+SUD.
Comorbidity of PTSD, Major Depression, and Substance Use Disorder among Adolescent Victims of the Spring 2011 Tornadoes in Alabama and Joplin, Missouri
(Taylor & Francis, 2015) Adams, Zachary W.; Danielson, Carla Kmett; Sumner, Jennifer A.; McCauley, Jenna L.; Cohen, Joseph R.; Ruggiero, Kenneth J.; Psychiatry, School of Medicine
Objective: The purpose of this study was twofold: (1) to estimate the prevalence of comorbid posttraumatic stress disorder (PTSD), major depressive episode (MDE), and substance use disorder (SUD); and (2) to identify risk factors for patterns of comorbidity among adolescents affected by disasters. Method: A population-based sample of 2,000 adolescents (51% female; 71% Caucasian, 26% African American) aged 12 to 17 years (M = 14.5, SD = 1.7) and their parents was recruited from communities affected by the spring 2011 tornadoes in Alabama and Joplin, Missouri. Participants completed structured telephone interviews assessing demographic characteristics, impact of disaster, prior trauma history, Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV), symptoms of posttraumatic stress disorder (PTSD) and major depressive episode (MDE), and substance use disorder (SUD) symptoms. Prevalence estimates were calculated for PTSD + MDE, PTSD + SUD, MDE + SUD, and PTSD + MDE + SUD. Hierarchical logistic regression was used to identify risk factors for each comorbidity profile. Results: Overall prevalence since the tornado was 3.7% for PTSD + MDE, 1.1% for PTSD + SUD, 1.0% for MDE + SUD, and 0.7% for PTSD + MDE + SUD. Girls were significantly more likely than boys to meet criteria for PTSD + MDE and MDE + SUD (ps < .05). Female gender, exposure to prior traumatic events, and persistent loss of services were significant risk factors for patterns of comorbidity. Parental injury was associated with elevated risk for PTSD + MDE. Adolescents should be evaluated for comorbid problems, including SUD, following disasters so that appropriate referrals to evidence-based treatments can be made. Conclusions: Results suggest that screening procedures to identify adolescents at risk for comorbid disorders should assess demographic characteristics (gender), impact of the disaster on the family, and adolescents' prior history of stressful events.
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.
Development and Pilot Evaluation of a Tablet-Based Application to Improve Quality of Care in Child Mental Health Treatment
(JMIR, 2015-12-30) Ruggiero, Kenneth J.; Bunnell, Brian E.; Andrews, Arthur R., III; Davidson, Tatiana M.; Hanson, Rochelle F.; Danielson, Carla Kmett; Saunders, Benjamin E.; Soltis, Kathryn; Yarian, Caleb; Chu, Brian; Adams, Zachary W.; Psychiatry, School of Medicine
Background: Children need access to high quality mental health care. Effective treatments now exist for a wide range of mental health conditions. However, these interventions are delivered with variable effectiveness in traditional mental health service settings. Innovative solutions are needed to improve treatment delivery quality and effectiveness. Objective: The aim of this study was to develop a scalable, sustainable technology-based approach to improve the quality of care in child mental health treatment. Methods: A tablet-based resource was developed with input from mental health training experts, mental health providers, and patients. A series of qualitative data collection phases (ie, expert interviews, patient and provider focus groups, usability testing) guided the initial concept and design of the resource, and then its refinement. The result was an iPad-based "e-workbook" designed to improve child engagement and provider fidelity in implementation of a best-practice treatment. We are currently conducting a small scale randomized controlled trial to evaluate the feasibility of e-workbook facilitated child mental health treatment with 10 providers and 20 families recruited from 4 local community-based mental health clinics. Results: Usability and focus group testing yielded a number of strong, favorable reactions from providers and families. Recommendations for refining the e-workbook also were provided, and these guided several improvements to the resource prior to initiating the feasibility trial, which is currently underway. Conclusions: This study aimed to develop and preliminarily evaluate a tablet-based application to improve provider fidelity and child engagement in child mental health treatment. If successful, this approach may serve as a key step toward making best-practice treatment more accessible to children and families. As various technologies continue to increase in popularity worldwide and within the health care field more specifically, it is essential to rigorously test the usability, feasibility, acceptability, and effectiveness of novel health technology solutions. It is also essential to ensure that patients and providers drive decision making that supports the development of these resources to ensure that they can be seamlessly integrated into practice.
Distress Tolerance and Social Support in Adolescence: Predicting Risk for Internalizing and Externalizing Symptoms Following a Natural Disaster
(Springer, 2016) Cohen, Joseph R.; Danielson, Carla Kmett; Adams, Zachary W.; Ruggiero, Kenneth J.; Psychiatry, School of Medicine
The purpose of the multi-measure, multi-wave, longitudinal study was to examine the interactive relation between behavioral distress tolerance (DT) and perceived social support (PSS) in 352 tornado-exposed adolescents aged 12–17 years (M=14.44; SD=1.74). At baseline, adolescents completed a computer-based task for DT, and self-report measures of PSS, depressed mood, posttraumatic stress disorder (PTSD), substance use, and interpersonal conflict. Symptoms also were assessed 4 and 12 months after baseline. Findings showed that lower levels of DT together with lower levels of PSS conferred risk for elevated symptoms of prospective depression (t(262)= −2.04, p=.04; reffect size=0.13) and PTSD (t(195)= −2.08, p=.04; reffect size=0.15) following a tornado. However, only PSS was significant in substance use t(139)=2.20, p=.03; reffect size=0.18) and conflict (t(138)=−4.05, p<.0001; reffect size=0.33) in our sample. Implications regarding adolescent DT, the transdiagnostic nature of PSS, and the clinical applications of our findings in the aftermath of a natural disaster are discussed.
Elucidating Dimensions of Posttraumatic Stress Symptoms and their Functional Correlates in Disaster-Exposed Adolescents
(Elsevier, 2014) Sumner, Jennifer A.; Pietrzak, Robert H.; Danielson, Carla Kmett; Adams, Zachary W.; Ruggiero, Kenneth J.; Psychiatry, School of Medicine
The aim of this study was to elucidate the dimensional structure of posttraumatic stress disorder (PTSD) and potential moderators and functional correlates of this structure in disaster-affected adolescents. A population-based sample of 2000 adolescents aged 12-17 years (M = 14.5 years; 51% female) completed interviews on post-tornado PTSD symptoms, substance use, and parent-adolescent conflict between 4 and 13 months (M = 8.8, SD = 2.6) after tornado exposure. Confirmatory factor analyses revealed that all models fit well but a 5-factor dysphoric arousal model provided a statistically significantly better representation of adolescent PTSD symptoms compared to 4-factor dysphoria and emotional numbing models. There was evidence of measurement invariance of the dysphoric arousal model across gender and age, although girls and older adolescents aged 15-17 years had higher mean scores than boys and younger adolescents aged 12-14 years, respectively, on some PTSD dimensions. Differential magnitudes of association between PTSD symptom dimensions and functional correlates were observed, with emotional numbing symptoms most strongly positively associated with problematic substance use since the tornado, and dysphoric arousal symptoms most strongly positively associated with parent-adolescent conflict; both correlations were significantly larger than the corresponding correlations with anxious arousal. Taken together, these results suggest that the dimensional structure of tornado-related PTSD symptomatology in adolescents is optimally characterized by five separate clusters of re-experiencing, avoidance, numbing, dysphoric arousal, and anxious arousal symptoms, which showed unique associations with functional correlates. Findings emphasize that PTSD in disaster-exposed adolescents is not best conceptualized as a homogenous construct and highlight potential differential targets for post-disaster assessment and intervention.
