Risk factors for adolescent substance abuse and dependence: data from a national sample

Experiences of victimization before resettlement and chronic disease among foreign-born people in the United States

Stressful experiences are common among migrants and may have health implications. With the only US nationally representative data set on migration, the New Immigrant Survey, we used survey-adjusted descriptive and multivariate regression methods to examine whether victimization prior to resettlement was associated with obesity, cardiovascular disease, diabetes, arthritis, cancer, and chronic lung disease. Among foreign-born people who obtained lawful permanent residence in the US in 2003-04, 6.7 per cent reported victimization before arriving in the US. Those who had experienced victimization more often suffered from chronic conditions than people without such experiences: they were 32 per cent more likely to suffer from at least one chronic condition (p < 0.05), especially cancer (4.36, p < 0.05), arthritis (1.77, p < 0.01), and cardiovascular disease (odds ratio 1.32, p < 0.05). These relationships were in part mediated by differences in healthcare access after arriving in the US between those who had experienced victimization and those who had not. Victimization may have consequences for integration and later-life chronic disease.

Childhood maltreatment as a predictor of substance use/misuse among youth: A systematic review and meta-analysis

This systematic review and meta-analysis aimed to comprehensively describe whether experiencing a variety of childhood maltreatment types predicts a variety of substance use/misuse types among youth, beyond the narrow scope covered in previous systematic reviews on similar topics. A literature search was conducted in June, 2022 using PubMed, PsycInfo, and Embase. 58 studies (total participant n=170,749) were included. These studies were primarily organized by substance type outcomes including alcohol (n=43), cannabis (n=25), unspecified substances (n=25), and other specific substances (n=10). Results were further stratified by maltreatment type. For specific maltreatment and substance type combinations, the majority of studies indicated that childhood maltreatment was a significant predictor of substance use/misuse in youth. Of the 10 meta-analyses we conducted, significant associations were found for the majority (9/10) of maltreatment and substance type combinations. For instance, unspecified childhood maltreatment increased the probability of youth alcohol use by about four times, which was the highest relative risk found. In conclusion, this study shows that childhood maltreatment is a predictor of youth substance use/misuse.

Using Passive and Active Data to Predict Post-Traumatic Stress Disorder Symptoms and Cannabis Use in Recently Discharged UK Veterans: A Protocol for the MAVERICK Feasibility Study

Introduction

Post-traumatic stress disorder (PTSD) and comorbid cannabis use disorder (CUD) is a growing concern amongst UK veterans. Co-occurrence of problematic cannabis use, and PTSD is associated with greater PTSD symptom severity, decreased likelihood of cannabis use cessation, worse clinical outcomes, and increased societal burden. Despite increased screening efforts among veterans, there are no effective strategies for predicting risk for PTSD and problematic drug use escalation before these conditions develop, worsen, or become chronic.

Methods

This feasibility study employs a 4-week (28 day) longitudinal design (daily data collection), multiple passive data collection features via a bespoke study smartphone app called MAVERICK, and active data collection via wearable technology to predict clinically meaningful escalations in cannabis use and PTSD symptoms in UK veterans. Questionnaire data will be collected between 06:00 and 10:00 each day. Passive data will be collected continuously in the background.

Results

The study will begin recruitment in June 2023 and will require 18 months to complete. Study results are expected to be published in January 2024.

Discussion

This trial will provide information on the feasibility and utility of a smartphone app (MAVERICK) to collect both active and passive data to predict PTSD symptoms and cannabis use in a UK veteran population. If the smartphone app is deemed feasible and acceptable to users, it has the potential to provide an effective measurement tool to mitigate risk of PTSD and problematic cannabis use among veterans.

"Weeding out" violence? Translational perspectives on the neuropsychobiological links between cannabis and aggression

Recent shifts in societal attitudes towards cannabis have led to a dramatic increase in consumption rates in many Western countries, particularly among young people. This trend has shed light on a significant link between cannabis use disorder (CUD) and pathological reactive aggression, a condition involving disproportionate aggressive and violent reactions to minor provocations. The discourse on the connection between cannabis use and aggression is frequently enmeshed in political and legal discussions, leading to a polarized understanding of the causative relationship between cannabis use and aggression. However, integrative analyses from both human and animal research indicate a complex, bidirectional interplay between cannabis misuse and pathological aggression. On the one hand, emerging research reveals a shared genetic and environmental predisposition for both cannabis use and aggression, suggesting a common underlying biological mechanism. On the other hand, there is evidence that cannabis consumption can lead to violent behaviors while also being used as a self-medication strategy to mitigate the negative emotions associated with pathological reactive aggression. This suggests that the coexistence of pathological aggression and CUD may result from overlapping vulnerabilities, potentially creating a self-perpetuating cycle where each condition exacerbates the other, escalating into externalizing and violent behaviors. This article aims to synthesize existing research on the intricate connections between these issues and propose a theoretical model to explain the neurobiological mechanisms underpinning this complex relationship.

Investigating CHRNA5, CHRNA3, and CHRNB4 variants in the genetic landscape of substance use disorder in Jordan

BACKGROUND

Substance use disorder (SUD) is a complex illness that can be attributed to the interaction between environmental and genetic factors. The nicotinic receptor gene cluster on chromosome 15 has a plausible association with SUD, particularly with nicotine dependence.

METHODS

This study investigated 15 SNPs within the CHRNA5, CHRNA3, and CHRNB4 genes. Sequencing was used for genotyping 495 Jordanian males with SUD and 497 controls matched for age, gender, and descent.

RESULTS

Our findings revealed that none of the tested alleles or genotypes were correlated with SUD. However, our analysis suggests that the route of substance use was linked to rs1051730 (P value = 0.04), rs8040868 (P value = 0.01) of CHRNA3, and rs16969968 (P value = 0.03) of CHRNA5. Additionally, a correlation was identified between rs3813567 of the CHRNB4 gene and the age at substance use onset (P value = 0.04).

CONCLUSIONS

Variants in CHRNA5, CHRNA3, and CHRNB4 may interact with SUD features that can influence the development and progression of the disorder among Jordanians.

Supporting Childhood Bereavement Through School-Based Grief Group

With 7.3% of children under the age of 18 experiencing the death of a parent and more who experience a loss of a loved one bereavement is a common experience in the lives of children and youth. The current study sought to evaluate the effectiveness of an 8-week, school-based grief group treatment program in reducing symptoms of grief, dysregulation, and improving social support. A total of 296 children and youth (age 11-18) participated in the grief programming provided by a local hospice agency. With a retention rate of 76% the researchers identified a significant reduction in grief symptomology, frequency of emotion dysregulation, and a significant increase in perceived social support from pre- to post-8-week school-based grief programming. A reduction in intensity of dysregulation was not significant. Implications for school personnel and parental support of children and youth experiencing loss are discussed.

Childhood trauma and alcohol misuse in college students: The moderating role of minimization

BACKGROUND

History of childhood trauma as a risk factor for alcohol misuse in early adulthood is very well documented. Given the associations between childhood trauma and alcohol misuse, more work is needed to understand the factors that influence this relationship.

OBJECTIVE

The purpose of this study was to examine the relationship between childhood trauma, minimization of such events and alcohol misuse in a French college student sample.

PARTICIPANTS AND SETTING

A convenience sampling method was used to recruit students from several colleges located in Western France. The data set included 1180 records with complete responses.

METHODS

This study employed a cross-sectional online survey. Data collection instruments included the Childhood Trauma Questionnaire Short-Form (CTQ-SF) and the Alcohol Use Disorders Identification Test (AUDIT).

RESULTS

The strength of the association between CTQ score and AUDIT total score was increased by minimization score (β = 0.122, p = .07). This result suggests that under-reporting childhood trauma experiences tends to increase the impact of such events on alcohol misuse.

CONCLUSION

These findings suggest that a tendency to minimize threatening childhood events may specifically be related to increased risk of greater alcohol misuse among college students. Therefore, it may be important for clinician to assess minimization of early events in students with a history of childhood trauma.

The Association Between Personality Traits and Substance Use Among Advanced Level Students in Western Province, Sri Lanka: A Cross-sectional Study

Background

While personality predominantly influences human cognition, emotion, and behavior, there is still an unresolved research gap concerning the association between personality and substance use within the Sri Lankan context.

Methods

This descriptive cross-sectional study aimed to investigate the association between personality traits and substance use among advanced-level students aged over 18 in Western province, Sri Lanka, in 2023. Data collection was carried out using self-administered paper-pencil questionnaires. The study variables were measured using the brief version of the Big Five Personality Inventory and the Alcohol, Smoking, and Substance Involvement Questionnaire. Data analysis involved the use of the chi-square test and Spearman correlation.

Findings

Of the 441 enrolled participants, 422 provided correct responses to the questionnaire. Among them, 154 (36.5%) reported substance use. The majority of students initiated substance use at the age of 17. The results reveal a significant association between the openness personality trait and substance use among advanced-level students in Western province. Additionally, there was a statistically significant positive correlation between the extroversion personality trait and amphetamine use among advanced-level students.

Conclusion

The findings highlight a significant association between specific personality traits, particularly openness and extroversion, and substance use among advanced-level students in Western province, Sri Lanka. These results emphasize the significance of considering personality factors in understanding and addressing substance use behaviors among youth populations. Further research and targeted interventions are necessary to delve deeper into these associations and develop effective prevention and intervention strategies.

Experiencing violence and other predictors of within-person same-day use of multiple substances in youth: a longitudinal study in emergency settings

Background: Although experiencing violence is a risk factor for substance use among youth, its association with same-day use of multiple substances (a form of polysubstance use) and mitigating factors is less well understood.Objectives: To identify whether prosocial factors modified the effect of experiencing violence on the frequency of same-day use, and examine gender-specific risk/protective factors for same-day use.Methods: We analyzed longitudinal data from a cohort of youth who use drugs aged 14-24 (n = 599; 58% male) presenting to an urban emergency department between 2009-2011 and assessed biannually for two years. Using Poisson-generalized linear models with person-level fixed effects, we estimated within-person associations between self-reported experiencing violence and same-day use and analyzed gender and peer/parent support as effect modifiers. We adjusted for negative peer influence, parental drug and alcohol use, family conflict, anxiety and depression, and age.Results: Overall, positive parental support corresponded to lower rates of same-day use (rate ratio [RR]:0.93, 95% CI:0.87-0.99) and experiencing violence was associated with higher rates of same-day use (RR:1.25, 95% CI:1.10-1.41). Violence exposure was a risk factor among males (RR:1.42, 95% CI:1.21-1.66), while negative peer influences and parental substance use were risk factors among females (RR:1.63, 95% CI:1.36-1.97 and RR:1.58, 95% CI:1.35-1.83, respectively). Positive peer support reduced the association between violence exposure and same-day use among males (RR:0.69, 95% CI:0.57-0.84, p < .05).Conclusions: Tailored interventions may address gender differences in coping with experiencing violence - including interventions that promote parental support among males and reduce influence from parental substance use among females.

Maternal cognitive functioning and psychopathology predict quality of parent-child relationship in the context of substance use disorder: A 15-month longitudinal study

This longitudinal study aimed to investigate the role of maternal cognitive functioning and psychopathology in parent-child relationship quality during residential treatment for mothers with Substance Use Disorder (SUD), in order to identify factors that may enhance or limit intervention effects.We assessed cognitive functioning (Esame Neuropsicologico Breve-2 [ENB-2]) and psychopathology (Symptom Checklist-90 Revised [SCL-90-R]) in 60 mothers diagnosed with SUD (Mage = 30.13 yrs; SD = 6.79) at treatment admission. Parent-child relationship quality was measured during free-play interactions using the Emotional Availability Scales every three months from admission (Child Mage = 17.17m; SD = 23.60) to the 15th month of the residential treatment.A main effect of maternal psychopathology and an interaction effect of time and cognitive functioning were found. More maternal psychopathology predicted lower mother-child relationship quality. Mothers with higher cognitive functioning presented a better treatment trajectory, with an increase in mother-child relationship quality, whereas mothers with lower cognitive functioning showed a decrease in relationship quality after initial improvement.These findings suggest that maternal psychopathology and cognitive functioning may influence the treatment of parent-child relationships in the context of SUD, although causality is not yet established. Implications for assessment and intervention are discussed.

Functional Domains of Substance Use and their Implications to Trauma: A Systematic Review of Neuroimaging Studies

Substance use disorder (SUD) is a significant health problem, and trauma exposure is a known risk factor for the escalation of substance use. However, the shared neural mechanisms through which trauma is associated with substance use are still unknown. Therefore, we systematically review neuroimaging studies focusing on three domains that may contribute to the overlapping mechanisms of SUD and trauma-reward salience, negative emotionality, and inhibition. Using PRISMA guidelines, we identified 45 studies utilizing tasks measuring these domains in alcohol, tobacco, and cannabis use groups. Greater reward, lesser regulation of inhibitory processes, and mixed findings of negative emotionality processes in individuals who use substances versus controls were found. Specifically, greater orbitofrontal cortex, ventral tegmental area, striatum, amygdala, and hippocampal activation was found in response to reward-related tasks, and reduced activation was found in the inferior frontal gyrus and hippocampus in response to inhibition-related tasks. Importantly, no studies in trauma-exposed individuals met our review criteria. Future studies examining the role of trauma-related factors are needed, and more studies should explore inhibition- and negative-emotionality domains in individuals who use substances to uncover clinically significant alterations in these domains that place an individual at greater risk for developing a SUD.

Neural correlates of negative life events and their relationships with alcohol and cannabis use initiation

OBJECTIVE

Negative life events (NLEs), e.g., poor academic performance (controllable) or being the victim of a crime (uncontrollable), can profoundly affect the trajectory of one's life. Yet, their impact on how the brain develops is still not well understood. This investigation examined the National Consortium on Alcohol and Neurodevelopment in Adolescence (NCANDA) dataset for the impact of NLEs on the initiation of alcohol and cannabis use, as well as underlying neural mechanisms.

METHODS

This study evaluated the impact of controllable and uncontrollable NLEs on substance use initiation in 207 youth who initiated alcohol use, 168 who initiated cannabis use, and compared it to 128 youth who remained substance-naïve, using generalised linear regression models. Mediation analyses were conducted to determine neural pathways of NLE impacting substance use trajectories.

RESULTS

Dose-response relationships between controllable NLEs and substance use initiation were observed. Having one controllable NLE increased the odds of alcohol initiation by 50% (95%CI [1.18, 1.93]) and cannabis initiation by 73% (95%CI [1.36, 2.24]), respectively. Greater cortical thickness in left banks of the superior temporal sulcus mediated effects of controllable NLEs on alcohol and cannabis initiations. Greater left caudate gray-matter volumes mediated effects of controllable NLEs on cannabis initiation.

CONCLUSIONS

Controllable but not uncontrollable NLEs increased the odds of alcohol and cannabis initiation. Moreover, those individuals with less mature brain structures at the time of the NLEs experienced a greater impact of NLEs on subsequent initiation of alcohol or cannabis use. Targeting youth experiencing controllable NLEs may help mitigate alcohol and cannabis initiation.

Characterizing patterns of substance use in trauma exposed youth

OBJECTIVE

Previous work investigating the impact of childhood trauma on substance use and co-occurring psychiatric disorders has primarily been conducted in adults or on specific trauma types. This limits understanding of traumas impact in childhood and how different types of traumas play a role. We sought to characterize substance use in a sample of trauma-exposed youth in the context of psychiatric comorbidities.

METHOD

1152 youth from the Texas Childhood Trauma Research Network (TX-CTRN) that were exposed to at least one trauma meeting DSM-5 Criterion A were assessed for current substance use and psychiatric diagnoses. Latent class analysis was used to identify patterns of substance use. To characterize these patterns, we examined if demographics, number of trauma types experienced, or childhood psychiatric disorders predicted class membership.

RESULTS

We identified four primary patterns of substance use: Non-use (66.1%), predominantly alcohol use (19.7%), predominantly cannabis use (4.5%), and polysubstance use (9.7%). Compared to the non-users, polysubstance users tended to be older, Non-Hispanic White, have experienced more types of trauma. They were also more likely to have fulfilled diagnostic criteria for suicidality and ADHD. Comparisons among the substance using classes were more nuanced.

CONCLUSION

The findings highlight the need for universal assessments of trauma, substance misuse, and mental health symptoms in youth as the presence or absence of their co-occurrence has implications for treatment.

Differences in parent and youth perceived neighborhood threat on nucleus accumbens-frontoparietal network resting state connectivity and alcohol sipping in children enrolled in the ABCD study

Purpose

Evidence has shown neighborhood threat (NT) as a social driver of emotional and brain development. Few studies have examined the relationship between NT and neural function. Altered functional connectivity in the nucleus accumbens (NAcc) with the frontoparietal network (FPN) has been implicated in the development of substance use, however, little is known about perceived NT-related brain function or downstream alcohol sipping during early adolescence. This study examined the longitudinal relationship between youth and combined youth/parent perceived NT, resting state functional connectivity (RSFC) of the NAcc-FPN, and alcohol sipping behavior during late childhood and preadolescence.

Methods

This study used data (N = 7,744) from baseline to 2-year follow-up (FU) of the Adolescent Brain Cognitive Development Study (ABCD; Release 4.0). Relationships between youth and combined youth/parent perceive NT, alcohol sipping (baseline to two-year FU), and NAcc-FPN (left/right) connectivity, adjusting for demographics, family/peer history of alcohol use, parental monitoring and warmth, externalizing symptoms, and site, were examined in a mediation model via PROCESS in R.

Results

Greater youth-reported NT at baseline was significantly associated with lower RSFC between the right (but not left) NAcc-FPN holding covariates constant (R2 = 0.01, B = -0.0019 (unstandardized), F (12, 7,731) = 8.649, p = 0.0087) and increased odds of alcohol sipping at baseline up to the two-year FU (direct effect = 0.0731, 95% CI = 0.0196, 0.1267). RSFC between the right NAcc-FPN did not significantly predict alcohol sipping at the two-year FU (b = -0.0213, SE = 0.42349, p = 0.9599; 95% CI = -0.8086, 0.8512). No significant relationships were observed for combined youth/parent report predicting alcohol sipping or NAcc-FPN connectivity.

Conclusion

Findings suggest notable reporting differences in NT. Combined youth/parent report did not reveal significant findings; youth perceived NT was related to increased likelihood of alcohol sipping and lower neural connectivity between the right NAcc-FPN during late childhood and early adolescence. NT context - and source of reporting - may be crucial in examining links with downstream neuronal function and health behaviors. Future research should investigate reward processing and threat as the cohort ages into later adolescence.

Patterns of alcohol use among middle school students in rural communities: Associations with community violence exposure

Stress-coping theory posits that exposure to stressors, such as community violence, increases risk for early alcohol initiation. The current study identified patterns of alcohol use in an ethnically diverse sample of early adolescents in rural communities, and examined relations between different forms of exposure to community violence and severity of adolescents' alcohol use patterns. Participants were 5011 middle school students (46.4% non-Hispanic White, 25.5% Latinx, and 13.4% Black; 50% female) living in rural communities in the southeastern United States. Latent class analysis identified subgroups that differed in their patterns of lifetime and past 30-day alcohol use, and subgroup differences in exposure to community violence. Five subgroups were identified: abstainers (56.5%), initiators of wine and beer (12.5%); moderately frequent wine and beer users (10.3%); moderately frequent wine, beer, and liquor users who got drunk (12.0%); and highly frequent wine, beer, and liquor users who got drunk (8.6%). Subgroups differed across sex, grade, and racial-ethnic background. Subgroups characterized by severe alcohol use reported more frequent exposure to community violence and physical victimization, while controlling for nonviolent stressors. Consistent with stress-coping theory, the results indicate that experiencing physical victimization and witnessing community violence robustly relate to adolescents' high-risk alcohol use.

The influence of aerobic exercise on model-based decision making in women with posttraumatic stress disorder

Individuals with PTSD often exhibit deficits in executive functioning. An unexplored aspect of neurocognitive functions associated with PTSD is the type of learning system engaged in during decision-making. A model-free (MF) system is habitual in nature and involves trial-and-error learning that is often updated based on the most recent experience (e.g., repeat action if rewarded). A model-based (MB) system is goal-directed in nature and involves the development of an abstract representation of the environment to facilitate decisions (e.g., choose sequence of actions according to current contextual state and predicted outcomes). The existing neurocognitive literature on PTSD suggests the hypothesis of greater reliance on MF vs MB learning strategies when navigating their environment. While MF systems may be more cognitively efficient, they do not afford flexibility when making prospective predictions about likely outcomes of different decision-tree branches. Emerging research suggests that an acute bout of aerobic exercise improves certain aspects of neurocognition, and thereby could promote the utilization of MB over MF systems during decision making, although prior research has not yet tested this hypothesis. Accordingly, the current study administered a lab-based two-stage Markov decision-making task capable of discriminating MF vs MB decision making, in order to determine if moderate-intensity aerobic exercise (either shortly after or 30-minutes after the exercise bout has ended) promotes greater engagement in MB behavioral strategies compared to light-intensity aerobic exercise in adult women with and without PTSD (N=61). Results revealed that control women generally displayed higher levels of MB behavior that was further increased following immediate exercise, particularly moderate-intensity exercise. By contrast, the PTSD group generally displayed lower levels of MB behavior, and exhibited greater MB behavior when completing the task following moderate-intensity aerobic exercise compared to light-intensity aerobic exercise regardless of whether there was a short or long delay between exercise and the task. Additionally, women with PTSD demonstrated less impairment in MB decision-making compared to controls following moderate-intensity aerobic exercise. These results suggest that an acute bout of moderate-intensity aerobic exercise boosts MB behavior in women with PTSD, and suggests that aerobic exercise may play an important role in enhancing cognitive outcomes for PTSD.

Prevalence and Predictors of Alcohol Use among School-Going Adolescents in Panama: A Population-Based Cross-Sectional Study

This study investigated the prevalence and predictors of alcohol use among school-going-age adolescents in Panama. Using a national school-based cross-sectional survey, data from a proportionate sample of school-going adolescents aged 13-17 years were obtained from the 2018 Panama Global School-based Student Health Survey [GSHS]. Data were analysed with a Pearson's Chi-square test and weighted binary logistic regression. The results were reported with their corresponding adjusted odds ratio (AOR) at a 95% confidence interval (CI) and level of significance set at p < 0.05. The prevalence of alcohol use among adolescents in Panama was 30.6%. The odds of alcohol use were lower among adolescents in a lower grade than those in upper grades, and lower in those who did not eat from a restaurant than those who ate from a restaurant. Further, the likelihood of alcohol use was significantly high among those who engaged in physical fights, were seriously injured, were mostly worried, and whose parents used any form of tobacco. Other results showed that the odds of alcohol use were high among sedentary respondents, those who had multiple sexual partners and those who used amphetamines. Based on the present findings, a collaborative approach (i.e., stakeholders- the Ministry of Social Development and the Ministry of Education- community-individual levels) towards the development and adherence of appropriate interventions aimed at reducing alcohol use is required in Panama. Specific preventive interventions would be fundamental in promoting a positive school climate to help reduce adolescents' alcohol use and, perhaps, other anti-social behaviours (e.g., physical fights and bullying).

The Future of the United States Overdose Crisis: Challenges and Opportunities

Policy Points People are dying at record numbers from overdose in the United States. Concerted action has led to a number of successes, including reduced inappropriate opioid prescribing and increased availability of opioid use disorder treatment and harm-reduction efforts, yet ongoing challenges include criminalization of drug use and regulatory and stigma barriers to expansion of treatment and harm-reduction services. Priorities for action include investing in evidence-based and compassionate policies and programs that address sources of opioid demand, decriminalizing drug use and drug paraphernalia, enacting policies to make medication for opioid use disorder more accessible, and promoting drug checking and safe drug supply.

Associations of alternative cannabis product use and poly-use with subsequent illicit drug use initiation during adolescence

RATIONALE

Specific cannabis products may differentially increase risk of initiating non-cannabis illicit drug use during adolescence.

OBJECTIVE

To determine whether ever- and poly-use of smoked, vaporized, edible, concentrate, or blunt cannabis products are associated with subsequent initiation of non-cannabis illicit drug use.

METHODS

High school students from Los Angeles completed in-classroom surveys. The analytic sample (N = 2163; 53.9% female; 43.5% Hispanic/Latino; baseline M age = 17.1 years) included students who reported never using illicit drugs at baseline (spring, 11th grade) and provided data at follow-up (fall and spring, 12th grade). Logistic regression models assessed associations between use of smoked, vaporized, edible, concentrate, and blunt cannabis at baseline (yes/no for each product) and any non-cannabis illicit drug use initiation-including cocaine, methamphetamine, psychedelics, ecstasy, heroin, prescription opioids, or benzodiazepines-at follow-up.

RESULTS

Among those who never used non-cannabis illicit drugs at baseline, ever cannabis use varied by cannabis product (smoked = 25.8%, edible = 17.5%, vaporized = 8.4%, concentrates = 3.9%, and blunts = 18.2%) and patterns of use (single product use = 8.2% and poly-product use = 21.8%). After adjustment for baseline covariates, odds of illicit drug use at follow-up were largest for baseline ever users of concentrates (aOR [95% CI] = 5.74[3.16-10.43]), followed by vaporized (aOR [95% CI] = 3.11 [2.41-4.01]), edibles (aOR [95% CI] = 3.43 [2.32-5.08]), blunts (aOR [95% CI] = 2.66[1.60-4.41]), and smoked (aOR [95% CI] = 2.57 [1.64-4.02]) cannabis. Ever use of a single product (aOR [95% CI] = 2.34 [1.26-4.34]) or 2 + products (aOR [95% CI] = 3.82 [2.73-5.35]) were also associated with greater odds of illicit drug initiation.

CONCLUSIONS

For each of five different cannabis products, cannabis use was associated with greater odds of subsequent illicit drug use initiation, especially for cannabis concentrate and poly-product use.

Depression and Substance Use as Consequences of Exposure to Family Violence: A Moderation Mediation and Self-Medication Hypothesis Study

Ample evidence exists suggesting that exposure to family violence leads to substance use and this relationship is moderated by gender; however, much is still unknown of the underlying mechanism of this relationship. Thus, the current study first examined whether exposure to family violence was associated with substance use. Then consistent with the self-medication hypothesis, we tested whether depressive symptoms mediated the relations between exposure to family violence and substance use. Finally, we examined the moderating effect of gender on the relationships among exposure to family violence and depressive symptoms/substance use (N = 1,850). Results suggest that exposure to family violence positively associated with substance use. Mediation results revealed that depressive symptoms explained the relationship between exposure to family violence and substance use. Moderation results indicated that males who were exposed to family violence were more likely to endorse depressive symptoms and more likely to use substances while controlling for sibling aggression victimization. This study provides new insight into the internalizing and externalizing symptoms of exposure to family violence, specifically for male adolescents. Implications are discussed.

Association of Recent Violence Encounters With Suicidal Ideation Among Adolescents With Depression

IMPORTANCE

Suicide prevention is an important component of depression management. Knowledge about depressed adolescents with increased risk for suicide can inform suicide prevention efforts.

OBJECTIVE

To describe the risk of documented suicidal ideation within a year following a diagnosis of depression and to examine how the risk of documented suicidal ideation differed by recent violence encounter status among adolescents with new depression diagnoses.

DESIGN, SETTING, AND PARTICIPANTS

Retrospective cohort study in clinical settings including outpatient facilities, emergency departments, and hospitals. Using IBM's Explorys database containing electronic health records from 26 US health care networks, this study observed a cohort of adolescents with new depression diagnoses from 2017 to 2018 for up to 1 year. Data were analyzed from July 2020 to July 2021.

EXPOSURES

Recent violence encounter was defined by a diagnosis of child maltreatment (physical, sexual, or psychological abuse or neglect) or physical assault within 1 year before depression diagnosis.

MAIN OUTCOMES AND MEASURES

The main outcome was diagnosis of suicidal ideation within 1 year following depression diagnosis. Multivariable adjusted risk ratios of suicidal ideation were calculated for overall recent violence encounters and for individual forms of violence.

RESULTS

Among a total of 24 047 adolescents with depression, 16 106 (67.0%) were female and 13 437 (55.9%) were White. A total of 378 had experienceda violence (hereafter, encounter group) and 23 669 had not (hereafter, nonencounter group). Following the diagnosis of depression, 104 adolescents with any past-year violence encounter (27.5%) documented suicidal ideation within 1 year. In contrast, 3185 adolescents in the nonencounter group (13.5%) experienced thoughts of suicide following the diagnosis of depression. In multivariable analyses, those with any violence encounter had 1.7 times (95% CI 1.4-2.0) higher risk of documented suicidal ideation compared with those in the nonencounter group (P < .001). Among different forms of violence, sexual abuse (risk ratio, 2.1; 95% CI, 1.6-2.8) and physical assault (risk ratio, 1.7; 95% CI, 1.3-2.2) were associated with significantly increased risk of suicidal ideation.

CONCLUSIONS AND RELEVANCE

Among adolescents with depression, persons who experienced past-year violence encounters showed a higher rate of suicidal ideation than those who had not. These findings highlight the importance of identifying and accounting for past violence encounters when treating adolescents with depression to reduce risk of suicide. Public health approaches to prevent violence may help to avert morbidity associated with depression and suicidal ideation.

Beyond Sexual Assault Prevention: Targeted Outcomes for Empowerment Self-Defense

Empowerment Self-Defense (ESD) has been shown to be effective in reducing risk of sexual assault victimization among women, but because research in this area is still in its infancy, less is known about additional intervention outcomes that may explain how and why the intervention is effective and about other ways that ESD affects students. The purpose of this study was to examine ESD instructor perspectives about intervention outcomes they perceive to be most important for their students. Using qualitative case-study methodology, interviews from 15 ESD instructors from the United States and Canada were conducted and analyzed using thematic analysis, which yielded six themes: Agency, boundaries, core beliefs, health and healing, somatic experiences, and gender and intersectionality, with each theme having two or more subthemes. Although some of these outcomes have been quantitatively evaluated in previous ESD studies, over half (n = 10) have not yet been empirically measured and are the focus of this article. These 10 outcomes include enactment, self-determination, nonverbal communication, relationship quality, self-worth, healing, physical strength and power, downregulation, support and solidarity, and societal-level changes. In addition to developing standardized tools to measure these outcomes, future research should quantitatively evaluate these outcomes across diverse student populations and explore their effect on producing the profound outcome associated with ESD, which is reduced risk for sexual assault victimization.

The impact of a violent community on mental health and the benefits of a sport program for social development

The aim of the present study was to evaluate the impact of a violent environment on mental health and the impact of a sport for social development (SSD) program on quality of life, mental distress symptoms, and heart rate variability (HRV). HRV and psychometric data were measured from 20 men professional athletes assisted by the SSD and 20 men living in the same violent community. The comparison of groups revealed greater sympathetic parameters of HRV, positive affect, and quality of life in the SSD group. Multiple regression analysis showed that the quality of life in the SSD group was positively predicted by positive affect, while in the control group the quality of life was negatively predicted by their history of traumatic events. Both groups reported high levels of exposure to traumatic events and posttraumatic stress symptoms. However, this study demonstrates the benefits of SSD programs in mental health.

Influences of poly-victimization on adolescents' pre-treatment cognitive motivations and post-treatment outcomes

INTRODUCTION

Substance use treatment outcomes are challenging to predict: myriad potentially relevant factors influence outcomes, including age, sex, motivations, and history of victimization.

METHODS

The current study seeks to assess these factors in adolescents through an evaluation of the relationship between distinct victimization profiles, sex, and cognitive factors related to substance use treatment outcomes-specifically motivation, self-efficacy, and reasons for quitting-and the relationship between these factors and posttreatment outcomes. We report sex differences in the prevalence of specific types of victimization; females are more likely than males to report poly-victimization alongside higher levels of traumagenic characteristics such as fearing for your life, chronic abuse, abuse by a trusted individual, or negative reactions to disclosure.

RESULTS

Adolescents who endorsed high levels of poly-victimization and high traumagenic characteristics reported a) higher motivation for treatment, b) more reasons for quitting substance use, c) lower self-efficacy, and d) fewer adjusted days abstinent posttreatment relative to their peers. We report several sex differences: emergent poly-victimization profiles are different for males and females, class membership has a differential proportion, and, last, associations between class membership and pre-treatment cognitive motivations and posttreatment outcomes vary by sex.

CONCLUSION

Clinicians working with adolescents who report poly-victimization should aim to leverage their motivation and reasons for quitting, as these factors are traditionally associated with positive outcomes. Last, interventions aimed at fostering self-efficacy may also be particularly important to improve long-term outcomes, specifically among adolescents with a history of poly-victimization.

Pattern of substance use and substance use disorder in adolescent learners at public secondary schools in Gaborone, Botswana

INTRODUCTION

Substance use amongst adolescents remains a global public health challenge. The potential negative health outcomes of substance use suggest the need to understand the pattern of use and the associated factors among adolescents. This study aimed to describe the prevalence of substance use, SUDs, and PD and the associated factors in adolescent learners at public schools in Gaborone, Botswana.

METHODS

A cross-sectional study was conducted at 13 public secondary schools in Gaborone among 742 students. Assessment tools included the World Health Organization drug questionnaire, DSM-5 interview for SUD, and the General Health Questionnaire-12.

RESULTS

The mean age (SD) of the participants was 15.26 (1.57) years, and there were more females (55.5%). Over two-fifths (44.6%) of learners reported psychoactive substance use in the past 12 months, and 31.5% meeting DSM 5 criteria for a SUD. Alcohol was the most used psychoactive substance (25.1%). Male gender (AOR = 1.94; 95% CI: 1.26-2.995), having a friend (AOR = 4.27; 95% CI: 2.68-6.78), or father (AOR = 1.87; 95% CI: 1.14-3.04), who uses substance, and higher levels of PD (AOR = 1.09; 95% CI: 1.03-1.17) remained significantly associated with SUD. Regular participation in religious activities negatively correlated with SUD (AOR = 0.61; 95% CI: 0.38-0.96).

CONCLUSION

The high prevalence of substance use and SUDs among in-school adolescents is concerning. Substance use programs need to include family-focused and religious-based therapy and youth empowerment in developing positive peer relationships. Also, they should be integrated with mental health screening to assess comorbid PD.

Sex differences in poly-victimization among youth experiencing homelessness prior to substance use treatment

BACKGROUND

Poly-victimization is common among youth experiencing homelessness (YEH) and youth in substance use treatment. To date, studies have not examined poly-victimization among these two intersecting populations.

OBJECTIVE

To examine heterogeneity in lifetime victimization experiences among youth reporting homelessness at substance use treatment entry; identify demographic predictors of victimization class membership; and associations between victimization and clinical characteristics at treatment intake.

PARTICIPANTS AND SETTING

1270 adolescents and young adults reporting past 90-day homelessness in a nationwide substance use treatment data set.

METHODS

Latent Class Analysis (LCA) and logistic regression were used to examine heterogeneity in poly-victimization experiences, and associations with demographics and clinical characteristics for males and females.

RESULTS

Four victimization classes emerged for males, and five victimization classes emerged for females. The prevalence of victimization and trauma characteristics were higher for females, except physical victimization, which was higher for males. Age, race/ethnicity, and sexual minority status were related to poly-victimization class membership, but not consistently across classes. Compared to low or single victimization classes, youth in the poly-victimization class had higher odds of post-traumatic stress disorder, major depressive disorder, and exchange sex (among females); Poly-victimization class membership was not associated with duration of recent homelessness or substance use disorder diagnoses, when compared to low/less complex victimization.

CONCLUSION

High rates of lifetime victimization were found for YEH in substance use treatment, with rates generally higher among females. Trauma-informed interventions are needed to address complex victimization experiences and poor mental health among unstably housed youth in treatment.

Test-retest reliability of fMRI during an emotion processing task: Investigating the impact of analytical approaches on ICC values

Test-retest reliability of fMRI is often assessed using the intraclass correlation coefficient (ICC), a numerical representation of reliability. Reports of low reliability at the individual level may be attributed to analytical approaches and inherent bias/error in the measures used to calculate ICC. It is unclear whether low reliability at the individual level is related to methodological decisions or if fMRI is inherently unreliable. The purpose of this study was to investigate methodological considerations when calculating ICC to improve understanding of fMRI reliability. fMRI data were collected from adolescent females (N=23) at pre- and post-cognitive behavioral therapy. Participants completed an emotion processing task during fMRI. We calculated ICC values using contrasts and β coefficients separately from voxelwise and network (ICA) analyses of the task-based fMRI data. For both voxelwise analysis and ICA, ICC values were higher when calculated using β coefficients. This work provides support for the use of β coefficients over contrasts when assessing reliability of fMRI, and the use of contrasts may underlie low reliability estimates reported in the existing literature. Continued research in this area is warranted to establish fMRI as a reliable measure to draw conclusions and utilize fMRI in clinical settings.

Longitudinal Associations Between Sexual Victimization and Substance Misuse Among High School Youth in Colorado

There are consistently high rates of sexual victimization and substance misuse among youth in the United States. Although there is a known relation between sexual victimization and substance use, there is a gap in the research regarding the magnitude and temporality of these associations. This study examined whether latent classes of sexual victimization and help-seeking attitudes longitudinally predict intentions of future substance misuse 7-10 months later. Students from nine Colorado high schools (N = 533; M = age 16 years) completed surveys across two consecutive school semesters. Latent class analysis was used to identify classes of students who experienced at least one form of sexual victimization (e.g., sexual harassment, unwanted sexual contact) according to 13 sexual victimization items, and level of positive attitudes regarding help-seeking for sexual victimization. Classes were compared on demographic characteristics and for distal outcomes of likelihood of future substance misuse (cigarettes, alcohol, cannabis, prescription drugs, and electronic vaping products) using latent class regression, controlling for previous intentions to use. At Time 1, four classes of sexual victimization were identified with two main classes for comparison: low odds of experiencing sexual victimization (60.1% of sample) and high odds of endorsing all forms of sexual victimization (7.7% of sample). The high sexual victimization class had higher proportions of male and transgender students, compared to other classes. At Time 2 (7-10 months later), students in the high sexual victimization class reported a significantly greater likelihood of future cigarette (p = .017) and prescription drug misuse (p = .007) when compared to the low sexual victimization class. There was no evidence that having higher positive attitudes towards help-seeking resulted in lower intentions to use substances in the future. These findings highlight that addressing sexual violence in prevention programming may have crossover effects of reducing substance misuse and other forms of violence among youth.

Coping Motives Mediate the Association of Trauma History with Problematic Cannabis Use in Young Adult Medical Cannabis Patients and Non-Patient Cannabis Users

Background: Despite evidence of the contribution of childhood trauma to the development of problematic cannabis use, its mediating pathways are largely unknown. Given the link between cannabis motives with trauma and problematic cannabis use, motives of use may represent a construct through which trauma impacts problematic cannabis use. Methods: A sample of 339 medical cannabis patient and non-patient young adult users from the Los Angeles area were sampled at baseline and one year later. The current study examined the impact of childhood trauma on problematic use through a variety of cannabis use motives. Results: Controlling for age, socioeconomic status, perceived stress, and baseline problematic use, endorsing the use of cannabis to cope with distress at baseline uniquely mediated the associations between different childhood trauma types (e.g., physical abuse, neglect, sexual trauma) and problematic use one year later. Experience of any childhood trauma was positively associated with coping motives, whereas emotional and physical abuse were positively associated with pain motives, and sexual abuse was positively associated with sleep motives. Using cannabis for coping and increasing attention/focus were also positively associated with higher problematic use, whereas using cannabis for sleep was inversely associated with problematic use one year later. Conclusions: The motives of coping with distress and inattention may represent intermediate constructs through which trauma leads to later problematic cannabis use. Results highlight the need to clarify the pathways between health and non-health-oriented motives and cannabis use over time.

Early life stress and substance use disorders: The critical role of adolescent substance use

Early life stress (ELS) is a well-established risk factor for many psychiatric and medical disorders, including substance use disorders (SUDs). The relationship between ELS and SUDs is complex and there are likely multiple pathways from ELS to adverse substance use outcomes. The association between ELS and substance use emerges in adolescence. Adolescence is a critical period in development during which substance exposure markedly increases risk for SUDs. Therefore, this review focuses on the literature supporting the hypothesis that ELS increases risk for the development of SUDs through its influence on adolescent substance use. We discuss studies substantiating the role of ELS in adolescent substance use and explore how internalizing and externalizing psychopathology may be antecedents of substance use in adolescence. We examine clinical work suggesting ELS sculpts the Hypothalamic-Pituitary-Adrenal (HPA) Axis and developing brain-particularly subcortical brain regions that underlie stress response, mesocorticolimbic brain systems associated with reward sensitivity, and prefrontal regions that underlie executive control-in a way that increases risk for adolescent substance use and SUDs. We further explore how substance use during adolescence alters structure and function of these same systems, and how brain changes following ELS and adolescent substance use may independently, additively, or interactively contribute to risk for addiction. We conclude by discussing how the current literature can inform interventions aimed at reducing risk for SUDs in individuals with a history of ELS.

Frontoparietal network activity during model-based reinforcement learning updates is reduced among adolescents with severe sexual abuse

Trauma and trauma-related disorders are characterized by impaired learning processes, including reinforcement learning (RL). Identifying which aspects of learning are altered by trauma is critical endeavor, as this may reveal key mechanisms of impairment and potential intervention targets. There are at least two types of RL that have been delineated using computational modeling: model-free and model-based RL. Although these RL processes differentially predict decision-making behavior, most research has examined the impact of trauma on model-free RL. Currently unclear whether model-based RL, which involves building abstract and nuanced representations of stimulus-outcome relationships, is impaired among individuals with a history of trauma. The present study sought to test the hypothesis of impaired model-based RL among adolescent females exposed to assaultive trauma. Participants (n = 60; 29 without a history of assault and 31 with a history of assault with and without PTSD) completed a three-arm bandit task during fMRI acquisition. Two computational models compared the degree to which participants' task behavior fit the use of a model-free versus model-based RL strategy. Although a history of assaultive trauma did not predict poorer model-based RL, greater sexual abuse severity predicted less use of model-based compared to model-free RL. Additionally, severe sexual abuse predicted less left frontoparietal network encoding of model-based RL updates. Altered model-based RL, which supports goal-directed behavior, may be an important route through which clinical impairment emerges among individuals with a history of severe sexual abuse and should be examined further in future studies.

Predictors of motives for marijuana use in African American adolescents and emerging adults

African American adolescents use marijuana at higher rates and may be more vulnerable to psychosocial risk factors for marijuana use, including depression, post-traumatic stress, and having substance-using peers, compared to Caucasian adolescents. Little is known about how these factors contribute to African American adolescents' motives for marijuana use. This study examined the roles of depressive and post-traumatic stress symptoms and substance-using peers on marijuana use motives among African American adolescents and emerging adults and whether these motives predicted marijuana use. Findings suggest that identifying motives for marijuana use may help improve approaches to reduce use among this population.

Young age and the risk of violent behaviour in people with severe mental disorders: prospective, multicentre study

Background

During adolescence and young adulthood people appear to be more prone to violent behaviour. A greater tendency to violent behaviour appears to be associated with hyperactivity, impulsivity and low tolerance for frustration and provocation in social settings.

Aims

This prospective cohort study aimed to evaluate rates of violent behaviour among young people with mental disorders, compared with older age groups.

Method

A total of 340 individuals with severe mental disorders (125 living in residential facilities and 215 out-patients) were evaluated at baseline with the SCID-I and II, Brief Psychiatric Rating Scale, Specific Level of Functioning scale, Brown–Goodwin Lifetime History of Aggression scale, Buss–Durkee Hostility Inventory, Barratt Impulsiveness Scale and State–Trait Anger Expression Inventory-2. Aggressive behaviour was rated every 15 days with the Modified Overt Aggression Scale (MOAS).

Results

The sample comprised 28 individuals aged 18–29 years, 202 aged 30–49 and 110 aged 50 and over. Younger age was associated with a personality disorder diagnosis, substance use disorder, being single and employed. These results were confirmed even controlling for the gender effect. The patterns of the cumulative MOAS mean scores showed that younger (18–29 years old) individuals were significantly more aggressive than older (≥50) ones (P < 0.001).

Conclusions

This study highlights how young age in people with severe mental disorders is correlated with higher levels of impulsivity, anger and hostility, confirming previous analyses. Our results may assist clinicians in implementing early interventions to improve anger and impulsivity control to reduce the risk of future aggressive behaviours.

Social Trust and Reciprocity Among Adolescent Girls Exposed to Interpersonal Violence

Trauma research has traditionally focused on altered emotion regulation and its role in psychopathology, whereas mechanisms of social behavior remain comparatively unexplored, particularly among adolescents. It has been previously reported that adolescents with histories of interpersonal violence (IV) demonstrate disrupted social learning, and the degree to which they are impaired during social interactions requiring trustful behaviors may be associated with their levels of anxiety. In the present study, 52 adolescent females (n = 26 control; n = 26 IV-exposed) between ages of 11 and 17 completed a multi-round adaptation of the Trust Game in which they interacted with a confederate peer run by a computer program, alternating between the roles of investor and investee. The task was designed to operationalize the social behaviors of trust and trust reciprocity, where the magnitude of the participants' monetary investment in the confederate during the investor role represented trust while the proportion of investment returned to the confederate in the investee role represented trust reciprocity. IV-exposed and control participants did not differ in trust (i.e., as investors); however, IV-exposed participants without anxiety diagnoses demonstrated lower trust than those with anxiety diagnoses. For trust reciprocity (i.e., as investees), there were again no differences between IV-exposed participants and controls; however, IV-exposed participants with anxiety diagnoses had increased trust reciprocity compared with both other groups. Similarly, caregiver-reported anxiety symptoms were associated with trust reciprocity behaviors among the IV-exposed adolescents. Findings suggest that IV exposure and associated anxiety impacts adolescents' trust behaviors, demonstrating potential mechanisms for maladaptive social behavior among trauma-exposed youth.

Cumulative Exposure to Neighborhood Conditions and Substance Use Initiation among Low-Income Latinx and African American Adolescents

PURPOSE

While previous research underscores the important role that neighborhood contexts play for child and adolescent health and well-being, how these neighborhood contexts influence substance use initiation among adolescents from low-income and ethnic minority families has been understudied.

METHODS

This study is a secondary analysis of data from the Denver Child Study a retrospective survey that uses a natural experiment aimed at assessing neighborhood effects on developmental outcomes of Latinx and African American adolescents (N = 736). Cox cause-specific hazards models were estimated to test: (1) the effects of cumulative exposure to neighborhood social disorder, neighborhood violent and property crime rates, and neighborhood social capital during preadolescence (ages 8-11) on the likelihood of initiating alcohol, cigarette, and marijuana use during adolescence (ages 12-18), after controlling for youth, caregiver, and household factors; and (2) whether the effects of these cumulative neighborhood factors vary by Latinx and African American ethnicity.

RESULTS

5.6% of adolescents in this study initiated cigarette use, 5.4% initiated alcohol use and 5.2% used marijuana for the first time during adolescence. The results indicate that exposure to neighborhood social disorder during preadolescence is a significant risk factor, especially for the initiation of cigarette use (HR = 1.36, 95% CI = 1.062-1.745, p = 0.015) particularly among Latinx adolescents (HR = 1.42, 95% CI = 1.031-1.966, p = 0.032).

CONCLUSIONS

The findings suggest the need for further research on the relationship between exposure to neighborhood social disorder and adolescent substance use initiation in order to develop and implement community-based prevention and intervention programs to reduce substance use initiation and facilitate healthy adolescent development.

Longitudinal Relations among Adolescent Risk Behavior, Family Cohesion, Violence Exposure, and Mental Health in a National Sample

Violence is a public health concern linked with mental health problems among adolescents, and risk behavior increases the likelihood of violence exposure. Family cohesion may attenuate the negative effects of risk behavior. The purpose of this study was to examine family cohesion as a moderator in the relation between risk behavior (substance use and delinquency) and violence exposure, and to explore longitudinal associations among cohesion, violence exposure, and subsequent mental health outcomes (PTSD and depression). Data were drawn from the National Survey of Adolescents-Replication, a nationally representative sample of 3604 adolescents, with data collected via structured phone interviews at three waves spanning a two-year period. Hypotheses were tested using longitudinal structural equation modeling. Findings revealed that high family cohesion attenuated the relation between risk behavior and subsequent violence exposure. Wave 2 violence exposure was associated with more Wave 3 mental health problems, but high family cohesion was related to fewer subsequent symptoms. Follow-up analyses revealed that family cohesion moderated the relation between risk behavior and experiencing, but not witnessing, violence. Several demographic associations were observed. Although risk behavior increases exposure to violence, and in turn, mental health problems, family cohesion may serve as a protective factor, attenuating the link between risk behavior and subsequent negative consequences. This effect emerged even when accounting for demographic and socioeconomic covariates. Interventions with adolescents should target family relationships as a protective factor to reduce risk of violence exposure and mental health problems, particularly for adolescents who are engaging in high-risk behaviors.

Psychological well-being and alcohol misuse among community-based veterans: results from the Veterans' Health Study

BACKGROUND

Maladaptive drinking is an increasing concern among military policy makers and healthcare providers. The goal of this study was to assess how social and psychological factors relate to alcohol problems among post-deployed US veterans and how problematic drinking is associated with well-being.

METHODS

Data were collected via a telephone survey from a random sample of veterans receiving their healthcare from a large non-VA hospital system in central Pennsylvania (N = 1730). Interviewers inquired about participants' current alcohol consumption, using the CAGE and AUDIT-C scales, and health-related outcomes (general psychological distress, major depression, and self-reported health status). Analyses included demographic, military and nonmilitary stressful events, use of alcohol or drugs to cope post-deployment, use of psychiatric services, and personality characteristics as independent variables. Our sample was 95% male, 96% White, and had a mean age of 59 years old (SD = 12 years).

RESULTS

Analyses included demographic, military and nonmilitary stressful events, use of alcohol or drugs to cope post-deployment, use of psychiatric services, and personality characteristics as independent variables. Our sample was 95% male, 96% White, and had a mean age of 59 years old (SD = 12 years). Analyses for our drinking measures show that those who used drugs or alcohol to cope post-deployment were more likely to be problematic drinkers, while positive personality characteristics such as agreeableness and conscientiousness were related to fewer drinking problems. Multivariate logistic regressions for our well-being measures found that alcohol misuse was not related to distress or depression, but that a positive score on the AUDIT-C was associated with a lower likelihood of poor self-rated health. Using alcohol or drugs to cope was related to higher distress.

DISCUSSION

We conclude that service providers might consider using post-deployment AUDIT-C and the drugs and alcohol coping questions when screening for possible alcohol and mental health problems among veterans.

Association of Child Abuse and Systemic Lupus Erythematosus in Black Women During Adulthood

OBJECTIVE

Exposure to psychosocial stressors may contribute to the onset of systemic lupus erythematosus (SLE) through dysregulation of the adaptive stress response. The present study was undertaken to assess the relationship of childhood physical and sexual abuse to risk of SLE among Black women.

METHODS

Using data from the Black Women's Health Study, we followed 36,152 women from 1995 through 2015 with biennial questionnaires. Women reported on exposure to abuse during childhood (up to age 11) in 2005. Self-reported cases of incident SLE were confirmed as meeting the American College of Rheumatology SLE classification criteria by medical record review. Cox proportional hazards regression models were used to estimate hazard ratios (HRs) and 95% confidence intervals (95% CIs) for SLE among women exposed to physical or sexual abuse during childhood, controlling for potential confounders.

RESULTS

We confirmed 101 cases of incident SLE and identified patients who had completed questions on child abuse during 670,822 person-years of follow-up. Both physical and sexual abuse during childhood were associated with statistically significant increases in SLE incidence. The HR for SLE associated with ≥2 episodes of severe sexual abuse compared to no abuse was 2.51 (95% CI 1.29-4.85) after adjustment for alcohol consumption, smoking, body mass index, oral contraceptive use, age at menarche, and parental education. The multivariable-adjusted HR for SLE with ≥5 episodes of severe physical abuse was 2.37 (95% CI 1.13-4.99).

CONCLUSION

Our results suggest that sexual and physical abuse during childhood increase SLE risk during adulthood among Black women. Research is necessary both to confirm this finding and to understand potential mediating mechanisms.

Protective Factors Against Vaping and Other Tobacco Use

BACKGROUND AND OBJECTIVES

Vaping has gained popularity among adolescents despite negative health consequences. Few studies have focused on factors that may protect against vaping. We sought to determine if future orientation, parental monitoring, school connectedness, and social support are associated with decreased risk of vaping and other forms of tobacco use.

METHODS

Data were obtained via anonymous school-based health behavior surveys among ninth- through 12th-graders in Pittsburgh, PA (n = 2487). Protective factors were assessed through validated Likert scale instruments. The primary outcome was recent (past 30-day) vaping. Additional outcomes included other forms of tobacco use and intention to quit tobacco products. Poisson regression models examined associations between protective factors and vaping and tobacco use outcomes.

RESULTS

Mean age was 15.7 years, 1446 (58.1%) respondents were female, and 671 youth (27.0%) reported recent vaping. Positive future orientation and high parental monitoring were associated with significantly lower prevalence of recent vaping (adjusted prevalence ratio: 0.84 [95% confidence interval: 0.73-0.97] and adjusted prevalence ratio: 0.73 [95% confidence interval: 0.62-0.85], respectively). There were no significant relationships between social support or school connectedness and vaping. All 4 protective factors were inversely associated with other forms of tobacco use. No factors were significantly associated with intent to quit tobacco products.

CONCLUSIONS

Findings reveal significant inverse associations between future orientation, parental monitoring, and vaping but no relationship between protective factors and intent to quit tobacco products. Developing interventions to foster protective factors in youth and their parental supports may inform primary prevention efforts to reduce vaping and other tobacco use.

Gray matter volume correlates of adolescent posttraumatic stress disorder: A comparison of manual intervention and automated segmentation in FreeSurfer

Exposure to early life trauma is common and confers risk for psychological disorders in adolescence, including posttraumatic stress disorder (PTSD). Trauma exposure and PTSD are also consistently linked to alterations in gray matter volume (GMV). Despite the quantity of structural neuroimaging research in trauma-exposed populations, little consensus exists amongst research groups on best practices for image processing method and manual editing procedures. The purpose of this report is to evaluate the utility of manual editing of magnetic resonance (MR) images for detecting PTSD-related group differences in GMV. Here, T1-weighted MR images from adolescent girls aged 11-17 were obtained and analyzed. Two datasets were created from the FreeSurfer reconall pipeline, one of which was manually edited by trained research assistants. Gray matter regions of interest were selected and total volume estimates were entered into linear mixed effects models with method (manual edits or automated) as a within-subjects factor and group dummy-coded with PTSD as the reference group. Consistent with prior literature, individuals with PTSD demonstrated reduced GMV of the amygdala compared to trauma-exposed and non-trauma exposed controls, independent of editing method. Our results demonstrate that amygdala GMV reductions in PTSD are robust to certain methodological choices and do not suggest a benefit to the time-intensive manual editing pipeline in FreeSurfer for quantifying PTSD-related GMV.

An open trial investigation of Treatnet Family among adolescents with substance use problems

•

Treatnet Family (TF) had a positive significant impact in reducing alcohol use.

•

After participating in the TF, the adolescents were engaged with significantly fewer friends who consumed substances and participated in antisocial behaviours.

•

The two most reported life events (i.e., “got in a lot of arguments or fights” and “had problems with drugs or alcohol”) before the intervention were significantly decreased at the follow-up assessment.

•

Based on parent’s/family member’s reports, there was a significant decrease in mental health problems across time.

Introduction

Studies that used evidence-based family therapies have demonstrated significant effects in reducing adolescent drug use and delinquent behaviours, and in reducing comorbid mental health problems. However, almost all these studies were conducted in high-income countries. The overall aim of the present study was to explore the effect of United Nations Office on Drugs and Crime’s (UNODC) Treatnet Family (TF) in reducing substance consumption, drug-related activities, reducing mental health problems, and in improving family interaction among adolescents with substance-use problems.

Method

Nineteen adolescents who had been referred to a community counselling clinic because of substance-use problems and their parents/family members participated in TF. They completed a set of questionnaires to measure substance use, family functioning, mental health problems, and life events at pre-, post-intervention as well as at a one month-follow-up assessment.

Results

TF had a positive significant impact in reducing alcohol use among adolescents with substance-use problems. The number of adolescents who smoked cigarettes and marijuana, and used amphetamines reduced across time. After participating in TF, the adolescents were involved with significantly fewer friends who consumed substances and participated in antisocial behaviours. Furthermore, parent/family member reported a significant decrease in mental health problems, and positive changes in adolescent’s behaviours.

Conclusion

The TF had a positive impact in reducing alcohol consumption and problems related to substance consumption among adolescents with substance-use problems when delivered by practitioners in routine community settings.

Examining the Link Between Childhood Physical Abuse and Risk for Violent Victimization in Youth and Young Adulthood in China

This study examines the association between childhood physical abuse and an increased risk for violent victimization in youth and young adulthood in China. It further assesses if this relationship is mediated by an individual's routine activities. Data used in this study were collected from more than 2,000 individuals of school-based samples in Changzhi, a city of over 3 million people in Northern China. Drawing from a survey that captures childhood physical abuse, violent victimization, and routine activities, this study uses negative binominal regression to examine the relationships between childhood physical abuse, routine activities, and violent victimization among Chinese youth and young adults. We find that individuals who were physically abused in childhood were at a greater risk for violent victimization in youth and young adulthood, and that an individual's routine activities (e.g., drinking) partially mediated this relationship. The findings from this study suggest that routine activity theory provides a useful framework for explaining the link between childhood physical abuse and risk for violent victimization in the Chinese context. Furthermore, our findings stress the importance of future research to look more closely at childhood experiences when studying future behaviors. In addition, our findings challenge beliefs held among Chinese parents about the acceptability of physical punishment to discipline children. These findings can be used to shape programs that create awareness of acceptable parenting practices in China.

A Longitudinal Examination of Interpersonal Violence Exposure, Concern for Loved Ones During a Disaster, and Web-Based Intervention Effects on Posttraumatic Stress Disorder Among Adolescent Victims of the Spring 2011 Tornadoes

Natural disasters are common and devastating, and can affect the mental health of adolescents. It is also common for adolescents to have histories of interpersonal violence (IPV). The current study was a secondary data analysis of a larger randomized clinical trial and examined the moderating effect of IPV history and concern for loved ones during a disaster on treatment condition effects on posttraumatic stress disorder (PTSD) symptoms over time among disaster-exposed adolescents. Participants (n = 979) were recruited postdisaster to participate in a randomized clinical trial examining the efficacy of a web-based intervention, Bounce Back Now (BBN), on mental health symptoms at 4 and 12 months postintervention. It was found that adolescents with an IPV history and who had caregivers that were concerned for loved ones during a disaster had more PTSD symptoms at baseline than those without such histories. Furthermore, caregiver concern for loved ones during a disaster moderated the effect of BBN on PTSD symptoms over time. Specifically, the BBN condition was most effective for adolescents who had caregivers who were concerned for loved ones during the disaster in reductions of PTSD symptoms over time. The current study provides further evidence for the use of technology-based interventions for individuals as a means to address mental health symptoms after a traumatic event, especially among those with more severe traumatic experiences.

An Assessment of the Role of Parental Incarceration and Substance Misuse in Suicidal Planning of African American Youth and Young Adults

Suicide rates among youth are increasing, and African American youth are becoming the most likely group to die by suicide in the USA. We utilized ecodevelopmental theory to investigate the relationship between parental incarceration and substance misuse and their association with suicidal planning in a sample of African American youth and young adults. Participants consisted of 190 African American youth and young adults living in public housing in a mid-Atlantic city in the USA who completed a youth health-risk behavior measure, and parental incarceration and substance misuse measures. Findings indicate males were significantly more likely than females to have devised a plan to die by suicide, especially if their mothers were incarcerated or their fathers had an alcohol problem. The findings of this study suggest several implications for health prevention and intervention efforts to reduce suicide-related risks among African American youth and young adults, including strategies that promote family-centered, evidence-based interventions that are culturally tailored to provide further insight into the best practices in suicide prevention.

Aerobic exercise and consolidation of fear extinction learning among women with posttraumatic stress disorder

This study tested whether aerobic exercise delivered during the consolidation window following fear extinction learning reduces the return of fear among women with posttraumatic stress disorder (PTSD). Participants (n=35) completed an initial clinical assessment followed by a 3-day fear acquisition, extinction, and recall protocol. On day 1, participants completed a fear acquisition training task in which one geometric shape (conditioning stimulus; CS+) was paired (with 50% probability) with a mild electric shock (unconditioned stimulus; US), while a different shape (CS-) was never paired with the US. On day 2 (24 h later), participants completed a fear extinction training task in which the CS+ no longer predicted administration of the US. Shortly following extinction, participants were randomly assigned to complete either moderate-intensity aerobic exercise (EX) or a light-intensity exercise control (CON) condition. On day 3 (24 h later), participants completed fear recall tests assessing the return of fear (spontaneous recovery, renewal, and reinstatement). Fear responding was assessed via threat expectancy ratings and skin conductance responses (SCR). In the threat expectancy ratings, there were no significant differences between groups in spontaneous recovery; however, EX significantly (p=.02) reduced threat expectancy ratings following reinstatement relative to CON. In SCR measures, there were no significant differences between groups in spontaneous recovery, renewal, or reinstatement. These results support a role for moderate-intensity aerobic exercise during the consolidation window in reducing threat expectations following reinstatement in women with PTSD. Research should continue to examine exercise as a potential method for improving the efficacy of exposure-based therapies. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT04113798.

Childhood Mistreatment, PTSD, and Substance Use in Latinx: The Role of Discrimination in an Omitted-Variable Bias

BACKGROUND

Childhood mistreatment (CM) has been associated with adult posttraumatic disorder (PTSD) and substance use disorders (SUDs) in the general population. Few studies have examined the role of PTSD in the CM-SUD association among Latinx. This cross-sectional study evaluated a theory-driven conceptual model with a specific focus on the impact of perceived discrimination, which may interfere with these associations.

METHOD

Using a nationally representative sample and structural equation modeling (SEM), the study evaluated the mediation of PTSD in the CM-SUD link, adjusting for or omitting discrimination and other sociodemographic variables that are known predictors of Latinx behavioral health. Multi-subsample analyses were then conducted to review nativity differences (US-born = 924.43% and immigrant = 1630.57%).

RESULTS

The fully specified final model (model 1, covariates adjusted) failed to show a significant mediation of PTSD in the tested link, but a direct detrimental effect group of discrimination, for all Latinx. The mediation was only supported, when treating discrimination and other covariates as omitted variables (model 5), which also showed additional direct and indirect effect of CM on SUD. In subsample analyses, models of US-born and immigrant-Latinx subpopulations were identical but showed nativity differences when omitting covariates.

CONCLUSION

When discrimination and other covariates were fully adjusted, Latinx exposed to trauma were more likely to develop SUD in adulthood, regardless of when traumatic exposure occurred. This unexpected finding challenges theories explaining the CM-SUD connection, suggesting possible model misspecifications of parametric SES; namely, omitting the unique impact of perceived discrimination in Latinx can lead to biased results. From a clinical standpoint, both trauma and discrimination must be addressed when assessing Latinx behavioral health.

Predictors of substance use in a clinical sample of youth seeking treatment for Trauma-related mental health problems

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.

A Neglected Population: Media Consumption, Perceived Risk, and Fear of Crime Among International Students

The 4.5 million international students worldwide bring in multifold benefits to the advancement of culture, economy, and national security in education host countries. Surprisingly, few prior studies have explored international students' fear of crime, which may harm their mental and physical health and undermine their educational achievements. The current study aims to fill in this research void by investigating international students' fear of crime in line with the cultivation theoretical framework, which postulates that media consumption cultivates fear of crime. The analyses draw on a sample of 398 international students attending nine different public and private universities across the United States. Using structural equation modeling (SEM), I investigate the extent and correlates of students' fear of crime. The findings reveal that international students are more fearful in the United States than in their home countries. SEM results show that controlling for students' fear in their home countries, attention paid to crime news is positively related to fear in the United States, through perceived victimization risk. The SEM results also suggest that exposure to non-U.S. social media (e.g., WeChat and Weibo) is positively related to respondents' fear of crime, whereas exposure to U.S. social media (e.g., Facebook and Twitter) is not related to fear of crime. The current study highlights the importance of studying the impact of fear of crime and social media use on international students.
