Prevalence of adolescent substance use disorders across five sectors of care

Adolescent substance use at the intersections of foster care, sexual orientation and gender identity, racial/ethnic identity, and sex assigned at birth

BACKGROUND

Lesbian, gay, bisexual, transgender, queer and questioning (LGBTQ) youth are overrepresented in foster care and report greater substance use during adolescence.

OBJECTIVE

Using an intersectional lens, the current study investigates differences in foster care placement and variation in substance use at the intersections of foster care and sexual orientation, gender identity, racial/ethnic identities, and sex assigned at birth.

PARTICIPANTS AND SETTINGS

A sample of 121,910 LGBTQ youth (grades 6-12) completed either the Minnesota Student Survey in 2019, the California Healthy Kids Survey from 2017 to 2019, or the 2017 LGBTQ National Teen Study.

METHODS

Youth reported their substance use in the past 30 days (alcohol, binge drinking, cigarette, marijuana), social positions (sexual orientation, gender identity, racial/ethnic identities, sex assigned at birth), living arrangement (foster care or not), and grade in school. Logistic regression was used to examine the main and interaction effects of foster care and social positions on youth substance use.

RESULTS

Results indicated significant differences in substance use at the intersection of foster care placement and youth social positions. Significant two-way interactions for foster care placement and social positions emerged predicting alcohol, binge drinking, and marijuana use.

CONCLUSIONS

Findings show that LGBTQ youth in foster care are at higher risk for substance use than those not in foster care. Particular support is needed for lesbian, gay, and questioning youth, transgender youth, LGBTQ youth assigned male at birth, and Asian or Pacific Islander LGBTQ youth in foster care.

Prevalence of Dual Diagnoses among Children and Adolescents with Mental Health Conditions

BACKGROUND

The World Health Organisation defines dual diagnosis as the co-occurrence in the same individual of a psychoactive substance use disorder and another psychiatric disorder. Children and adolescents with dual diagnoses represent a significant public health burden in social and financial terms.

AIMS

The objective of the present paper is to provide a review of studies dealing with dual diagnoses and their prevalence among children and adolescents whose primary treatment involves psychiatric conditions.

METHODS

The PRISMA was used to conduct a systematic search. Articles published between January 2010 and May 2022 were searched for analysis.

RESULTS

Eight articles were eventually found eligible for the final content analysis. The analysis of the articles identified the prevalence of dual diagnoses among children and adolescents treated primarily for psychiatric conditions, the gender-specific occurrence of dual diagnoses, methods used to diagnose psychiatric and substance use disorders, types of psychiatric diagnoses involved in dual diagnoses, and prevalence differences contingent on the type of service provision as the main thematic areas. The prevalence of dual diagnoses among the target population ranged from 18.3% to 54% (mean 32.7%). Boys were more likely to experience dual diagnoses and affective disorders were the most frequent psychiatric diagnoses.

CONCLUSION

The importance of the issue and the high prevalence of dual diagnoses make it imperative that this type of research is pursued.

Resources for the Assessment and Treatment of Substance Use Disorder in Adolescents

Substance Use Disorder (SUD) is understood as the persistent use of substances to the detriment of the individual's livelihood and wellness. SUD can have serious mental, physical, and social ramifications if not properly addressed. Though SUD can develop at any age, it is especially important to address in adolescents, given rising prevalence of certain substances (e.g. cannabis) in that age group and poor prognosis associated with early-onset SUD.[1][2] Data from the National Survey on Drug Use and Health show the lifetime use of illicit drugs in people ages 12-17 is 20.9%.[3] The same survey found the rate of Substance Use Disorder in the past year for people ages 12-17 who used illicit drugs or alcohol to be 6.3% in 2020.[3] This paper is intended for clinicians and lay people to gain a deeper understanding of SUD in adolescents, particularly relating to alcohol, cannabis, nicotine, and opioids. Though alcohol, cannabis, and nicotine are the substances most commonly used by this age demographic nationally,[4] opioid use – and resulting deaths – have been on the rise. According to the Centers for Disease Control and Prevention (CDC), opioids were connected to about 75% of the nearly 92,000 drug deaths in 2020.[5] Beyond significant death rates in the general population, recent spikes in adolescent death rate tied to the synthetic opioid fentanyl – which held a relatively stable death rate from 2010 to 2019 until seeing a 94% increase from 2019 to 2020 and additional 20% increase to 2021 - warrants inquiry into opioids for this population.[6] Each of these substances can have adverse, long-lasting effects on health if not managed properly, resulting in seriously compromised lifelong wellbeing.[7] This article explores SUD prevalence and reviews diagnostic criteria in relation to adolescence, including a synopsis of changes in SUD classification between the DSM-IV and DSM-5 and discussion of ICD-11 and the Research Domain Criteria (RDoC) as a basis for research related to substance use. Effective assessment and consideration of co-occurring disorders are covered as well. Although the prognosis of SUD varies by an individual's environment and circumstances, a modal developmental course for SUD is discussed. Finally, a curated list of nationally recognized resources including hotlines, treatment locators, informational sites, and support groups is provided, along with tools to compile local resources. By addressing these aspects of adolescent SUD, the research team offers a broader view of its prevalence in the United States, key warning signs and comorbidities, and possible assessments and treatments for adolescents with SUD.

Rapid and Deferred Help Seeking Among African American Parents of Children With Emotional and Behavioral Difficulties

OBJECTIVE

Little is known about the factors African American parents consider when seeking care for their child after emotional and behavioral difficulties emerge. This study aimed to examine factors associated with seeking professional care within 30 days after identifying a child's need (i.e., rapid care seeking) and with deferring care for ≥1 year.

METHODS

This cross-sectional study surveyed African American parents raising a child with emotional or developmental challenges (N=289). Logistic regression was used to examine associations of parent activation, medical mistrust, and care-seeking barriers with two outcomes: rapidly seeking care and deferring care seeking.

RESULTS

About 22% of parents rapidly sought care, and 49% deferred care for 1 year or longer. Parents were more likely to rapidly seek care if they had higher parent activation scores; lived with other adults with mental health challenges; or, contrary to the authors' hypothesis, mistrusted doctors. Parents were less likely to rapidly seek care if the challenge did not initially bother them much or if their health insurance would not cover the service. Parents were more likely to defer care if they feared involuntary hospitalization for their child or if their health insurance would not cover the service. Parents were less likely to defer care if they had at least some college education or lived with other adults with mental health challenges.

CONCLUSIONS

Community-based pediatric and child welfare professionals should be informed about facilitators and barriers to mental health care seeking as part of efforts to develop interventions that support African American families.

Efficacy of psychotropic medications on suicide and self-injury: a meta-analysis of randomized controlled trials

Using psychotropic medications to treat and prevent self-injurious thoughts and behaviors (SITBs) has become increasingly popular, but conclusive evidence supporting the efficacy this approach remains elusive. To empirically examine whether psychotropic medications are efficacious treatments for SITBs, the present meta-analysis comprehensively summarizes all published randomized controlled trials (RCTs) that have reported the causal effects of psychotropic medications on suicide and self-injury. A total of 251 papers from 718 unique RCTs were included. A frequentist pairwise approach was adopted for meta-analyses. Potential effect modifiers were examined via met regressions and potential biases were evaluated through sensitivity analyses. On average, medications yielded an 8% reduction in SITB frequency and a reduction of 0.2 standard deviations in symptoms and severity. Findings were largely consistent across potential effect modifiers, and significant evidence of publication bias was not detected. Only one medication class (i.e., antipsychotics) and two specific medications (i.e., citalopram, ketamine) produced larger-than-average treatment effects. Psychostimulants and typical antipsychotics may produce iatrogenic effects. Less than 4% of included studies required individuals to exhibit SITBs, and nearly half of analyzed effects were drawn from studies that excluded individuals on the basis of SITB risk. Taken together, findings suggest that psychotropic medications produce small treatment effects on SITBs; however, these findings should be considered in light of the methodological constraints of the existing literature, including the lack of studies intentionally including individuals with SITBs. It is critical for future RCTs to prioritize including individuals with existing SITBs to further clarify treatment effects in self-injurious and suicidal populations. Additional research is needed to better understand the treatment mechanisms of psychotropic medications and identify the causal processes underlying SITBs.

Behavioral and electrophysiological indices of inhibitory control in maltreated adolescents and nonmaltreated adolescents

Early adverse experiences are believed to have a profound effect on inhibitory control and the underlying neural regions. In the current study, behavioral and event-related potential (ERP) data were collected during a go/no-go task from adolescents who were involved with the child welfare system due to child maltreatment (n = 129) and low-income, nonmaltreated adolescents (n = 102). The nonmaltreated adolescents were more accurate than the maltreated adolescents on the go/no-go task, particularly on the no-go trials. Paralleling the results with typically developing populations, the nonmaltreated adolescents displayed a more pronounced amplitude of the N2 during the no-go trials than during the go trials. However, the maltreated adolescents demonstrated a more pronounced amplitude of the N2 during the go trials than during the no-go trials. Furthermore, while the groups did not differ during the go trials, the nonmaltreated adolescents displayed a more negative amplitude of the N2 than the maltreated adolescents during no-go trials. In contrast, there was not a significant group difference in amplitude of the P3. Taken together, these results provide evidence that the early adverse experiences encountered by maltreated populations impact inhibitory control and the underlying neural activity in early adolescence.

Policy Makers' Priorities for Addressing Youth Substance Use and Factors That Influence Priorities

OBJECTIVE

Understanding public policy makers' priorities for addressing youth substance use and the factors that influence these priorities can inform the dissemination and implementation of strategies that promote evidence-based decision making. This study characterized the priorities of policy makers in substance use agencies of U.S. states and counties for addressing youth substance use, the factors that influenced these priorities, and the differences in priorities and influences between state and county policy makers.

METHODS

In 2020, a total of 122 substance use agency policy makers from 35 states completed a Web-based survey (response rate=22%). Respondents rated the priority of 14 issues related to youth substance use and the extent to which nine factors influenced these priorities. Data were analyzed as dichotomous and continuous variables and for state and county policy makers together and separately.

RESULTS

The highest priorities for youth substance use were social determinants of substance use (87%), adverse childhood experiences and childhood trauma (85%), and increasing access to school-based substance use programs (82%). The lowest priorities were increasing access to naloxone for youths (49%), increasing access to medications for opioid use disorder among youths (49%), and deimplementing non-evidence-based youth substance use programs (41%). The factors that most influenced priorities were budget issues (80%) and state legislature (69%), federal (67%), and governor priorities (65%). Issues related to program implementation and deimplementation were significantly higher priorities for state than for county policy makers.

CONCLUSIONS

These findings can inform the tailoring of dissemination and implementation strategies to account for the inner- and outer-setting contexts of substance use agencies.

Agreement between Youth Self-Report and Biospecimen-Confirmed Substance Use: A Systematic Review

ContextBiospecimen analysis may enhance confidence in the accuracy of self-reported substance use among adolescents and transitional age youth (TAY). Associations between biospecimen types and self-reported use, however, are poorly characterized in the existing literature. Objective: We performed a systematic review of associations between biospecimen-confirmed and self-reported substance use. Data sources: PubMed, Embase, and Web of Science. Study selection: We included studies documenting associations between self-reported and biospecimen-confirmed substance use among adolescents (12-18 years) and TAY (19-26 years) published 1990-2020. Data extraction: Three authors extracted relevant data using a template and assessed bias risk using a modified JBI Critical Appraisal Tool. Results: We screened 1523 titles and abstracts, evaluated 73 full texts for eligibility, and included 28 studies. Most studies examined urine (71.4%) and hair (32.1%) samples. Self-report retrospective recall period varied from past 24 h to lifetime use. Agreement between self-report and biospecimen results were low to moderate and were higher with rapidly metabolized substances (e.g., amphetamines) and when shorter retrospective recall periods were applied. Frequently encountered sources of potential bias included use of non-validated self-report measures and failure to account for confounding factors in the association between self-reported and biospecimen-confirmed use. Limitations: Study heterogeneity prevented a quantitative meta-analysis. Studies varied in retrospective recall periods, biospecimen processing, and use of validated self-report measures. Conclusions: Associations between self-reported and biospecimen-confirmed substance use are low to moderate and are higher for shorter recall periods and for substances with rapid metabolism. Future studies should employ validated self-report measures and include demographically diverse samples.

Adolescent substance use: Challenges and opportunities related to COVID-19

Adolescent substance use is a significant public health concern within the United States that remains largely undertreated. The COVID-19 pandemic has exacerbated many preexisting risk factors for adolescent substance use, such as early life stress, social isolation, school connection, and boredom. Other effects include the potential for arrest in adolescent development, which can occur when there is disruption in expected developmental milestones. New cohorts of adolescents who may not otherwise initiate substances may now be at risk. The pandemic is also straining family systems, with potential for increased conflict and relapse that can occur in a bidirectional fashion. In parallel, the way in which we treat substance use disorders in youth has also shifted, with a dominance in digitally based platforms for delivery of most outpatient treatment. Challenges to utilizing virtual technology include fewer means of monitoring substance use remotely; privacy concerns; and ease of nonadherence with treatment by signing off the computer. Practitioners can utilize considerable opportunities for virtual care to reach adolescents at risk of developing a substance use disorder and/or those who may already have relapsed. Primary care providers and other general practitioners who frequently interface with youth should increase their baseline screening of youth.

Carisoprodol Abuse in Adolescence

Carisoprodol (i.e. Soma, Soprodol, Vanadom) is a muscle relaxant prescribed to relieve symptoms of muscle pain. Carisoprodol's addiction potential in adults has been well-established through case reports in the past. Carisoprodol abuse in adolescents has been reported in the ‘Monitoring the Future’ study since 2007, but no case studies or research has been published to date. Due to its relatively short half-life, tolerance and dependence develop quite quickly, leading to negative mental health outcomes. Awareness and education among health care providers remain critical to screen and treat this condition.

Substance use prevention services in juvenile justice and behavioral health: results from a national survey

BACKGROUND

This study examined the national availability of substance use prevention (SUP) within juvenile justice (JJ) and their primary behavioral health (BH) providers, and the relationships between the availability of SUP and agency-level measures of organizational structure, staffing, and youth characteristics. A three-stage national probability sampling process was used to select participants for a national survey that included, among other facets of community supervision (CS) and BH practices, questions on agency characteristics, youth characteristics, whether the agency/provider directly provided SUP services, and whether the agency/provider directly provided substance use and/or mental health treatment. This paper focuses on SUP services along with agency/provider and youth characteristics related to providing SUP.

RESULTS

The response rate for both CS agencies (n = 195) and BH providers (n = 271) was 96%. Complex samples logistic regression initially examined univariate associations of each variable and identified candidates for a final multivariate model. Overall, only one-third of CS and BH providers reported offering SUP services, with BH providers being significantly more likely than CS agencies to provide SUP services. In addition, likelihood of SUP was significantly lower among agencies where the substance use distribution of the caseload was below the median. Controlling for master's level staff and the substance use distribution, CS agencies were about 67% less likely to offer SUP when compared to BH providers.

CONCLUSIONS

Given the high rates of substance use among justice-involved youth and that substance use is an established risk for several negative behaviors, outcomes, and health conditions, these findings suggest that evidence-based prevention services should likely be expanded in justice settings, and perhaps included as part of CS programs, even when youth do not initially present with SU service needs.

Organizational Context and Individual Adaptability in Promoting Perceived Importance and Use of Best Practices for Substance Use

This study examines associations among organizational context, staff attributes, perceived importance, and use of best practices among staff in community-based, juvenile justice (JJ) agencies. As part of the National Institute on Drug Abuse's Juvenile Justice-Translational Research on Interventions for Adolescents in the Legal System (JJ-TRIALS) study, 492 staff from 36 JJ agencies were surveyed about the perceived importance and use of best practices within their organization in five substance use practice domains: screening, assessment, standard referral, active referral, and treatment support. Structural equation models indicated that supervisory encouragement and organizational innovation/flexibility were associated with greater individual adaptability. Adaptability (willingness to try new ideas, use new procedures, adjust quickly to change), was positively correlated with importance ratings. Importance ratings were positively associated with reported use of best practices. Organizational climates that support innovation likely affect use of practices through staff attributes and perceptions of the importance of such services.

Falling between two systems of care: Engaging families, behavioral health and the justice systems to increase uptake of substance use treatment in youth on probation

Justice-involved youth (JIY) in the US have high rates of substance use (SU) problems, yet 50%-80% of these youth do not receive necessary services. There has been no systematic exploration of the use of treatment services for JIY that examines viewpoints across stakeholders in justice- and treatment-systems as well as the families. We conducted qualitative interviews and focus groups with n = 58, youth, their caregivers, SU treatment providers and probation officers in a Northeastern state. Interviews explored how families, staff- and system-level factors influence uptake of and retention in SU treatment services in youth on probation. We conducted a thematic analysis of all interview texts. Caregiver engagement is essential for youth treatment uptake and retention. Difficulties achieving caregiver engagement and agreement that treatment was necessary stemmed from distrust in the "system"; denial or minimization of youth's SU problem; relational barriers; and overburden and chaos within the family system. Structural barriers to service uptake were lack of available treatment options, SU agency practices and policies, and interagency collaboration between SU treatment agencies and probation. Enhancing family engagement at the point of referral to SU treatment is essential. Improvements in interagency collaboration and communication between SU treatment and probation agencies are necessary. Implications for policy and intervention are discussed.

Geographic differences in substance use screening for justice-involved youth

Justice-involved youth report high rates of substance use. Community Supervision (CS) agencies are uniquely positioned to impact public health through substance use identification and early intervention. Geographic location (i.e., living in an urban versus rural area) is an understudied factor that can be associated with differences in service and resource availability. A secondary analysis of a nationally representative sample of CS agencies assessed agency and youth characteristics, as well as substance use screening in urban and rural CS agencies. Respondents representing rural agencies reported higher rates of substance use, yet were less likely to report using screeners focused on substance use. Respondents representing urban CS agencies reported a wider variety of screening instruments and were more likely to test for drug use during screening. Differences in the screening process can reflect adaptive and culturally responsive approaches to addressing substance use as well as unique barriers to service provision. System-wide improvement is contingent upon implementation strategies that identify and acknowledge geographic differences to more adequately address the common and unique needs of the justice-involved youth they serve.

Racial/ethnic differences in alcohol use trajectories among adolescents involved in child welfare

This study examined racial/ethnic differences in growth trajectories of alcohol use for a nationally representative sample of U.S. adolescents in the child welfare system (CWS), and how individual, family, and child welfare (i.e., proximal) factors predicted alcohol use trajectories for these adolescents. The study included 1,080 Hispanic, African American, and White adolescents aged 11 to 14 years old (at baseline) from the National Survey of Child and Adolescent Well-Being dataset, which is a nationally representative sample of U.S. children in the CWS. Latent growth modeling was used to determine alcohol use growth over 36 months, and multigroup analyses were conducted to examine racial/ethnic differences on alcohol use trajectories and the proximal factors predicting these trajectories. Findings indicated that CWS adolescents demonstrated similar trends in alcohol use growth and initiation compared to adolescents in the general population, especially the Hispanic CWS adolescents. This may reflect an overall shift in nativity status of Hispanic youth in the overall U.S. population. African American adolescents had the fewest significant predictors; this may suggest that factors more relevant for these adolescents and their alcohol use are missing from CWS research. Family-level factors were found to differentially affect use for CWS adolescents compared to adolescents in the general population. Overall, these findings point to a need for improvements in the assessment of CWS adolescents of color in research and practice settings to fully capture the complexity of experiences for these youth and their families.

Cross-sectoral integration in youth-focused health and social services in Canada: a social network analysis

Background

Youth with concurrent substance use and mental health concerns have diverse psychosocial needs and may present to a multitude of clinical and social service sectors. By integrating service sectors at a system level, the diversity of needs of youth with concurrent disorders can be addressed in a more holistic way. The objective of the present study was to quantify the level of cross-sectoral integration in youth-focused services in Canada.

Methods

Social network analysis (SNA) was used to examine the relationships between eight sectors: addictions, child welfare, education, physical health, housing, mental health, youth justice, and other social services. A total of 597 participants representing twelve networks of youth-serving agencies across Canada provided information on their cross-sectoral contacts and referrals.

Results

Overall, results suggested a moderate level of integration between sectors. The mental health and the addictions sectors demonstrated only moderate integration, while the addictions sector was strongly connected with the youth justice sector.

Conclusions

Despite evidence of moderate integration, increased integration is called for to better meet the needs of youth with concurrent mental health and substance use concerns across youth-serving sectors. Ongoing efforts to enhance the integration between youth-serving sectors should be a primary focus in organizing networks serving youth with concurrent mental health and substance use needs.

Poly-victimization and trajectories of binge drinking from adolescence to young adulthood among serious juvenile offenders

BACKGROUND

Justice involved youth exposed to multiple forms of victimization (i.e., poly-victimization) may be at risk for long term substance use problems and difficulty in self-regulation, placing them at higher risk of long-term problematic behaviors. This study empirically identifies victimization classifications in a sample of justice involved youth and how long-term binge drinking is related to victimization experiences. We further sought to understand how self-regulatory abilities such as impulse control and emotion regulation effect emergent profiles and binge drinking trajectories.

METHODS

Based on a sample of 1354 justice involved youth from 15 to 25 years old, classes of victimization were extracted. Emergent classes were examined in relationship to their binge drinking trajectories using latent growth models. Finally, self-regulation was examined as a predictor of binge drinking trajectories across emergent classes.

RESULTS

The analyses indicated three classes of victimization: poly-victimized, indirectly victimized, and lowly victimized. Latent growth models revealed that the poly-victimized class had significantly steeper growth in binge drinking as compared to the indirect and low victimized patterns. Impulse and emotional regulation both significantly decelerated binge drinking only for the indirect victimization group.

CONCLUSIONS

Findings highlight the need to focus on poly-victimization in understanding binge drinking trajectories as well as the role impulse control and emotional regulation play among justice involved youth. Findings are discussed through the lens of adolescent development, coping strategies, and early traumatic experiences.

Child maltreatment and age of alcohol and marijuana initiation in high-risk youth

INTRODUCTION

Youth with a history of child maltreatment use substances and develop substance use disorders at rates above national averages. Thus far, no research has examined pathways from maltreatment to age of substance use initiation for maltreated youth. We examined the longitudinal impact of maltreatment in early childhood on age of alcohol and marijuana use initiation, and whether internalizing and externalizing behaviors at age 8 mediates the link between maltreatment and age of substance use initiation.

MATERIALS AND METHODS

Data were drawn from the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN) at ages 4, 8, 12, and 18. Maltreatment was assessed through reviews of administrative records and youth self-reports. Behavior problems were assessed with the Child Behavior Checklist. Age of substance use initiation was assessed with the Young Adult version of the Diagnostic Interview Schedule for Children.

RESULTS

Path analyses indicated mediated effects from a history of maltreatment to age at first alcohol and marijuana use through externalizing behaviors. Considering type of maltreatment, direct effects were found from physical abuse to age of alcohol initiation, and mediated effects were found from sexual abuse and neglect to initial age of alcohol and marijuana use through externalizing behaviors. Direct effects for marijuana use initiation and indirect effects through internalizing behavior problems were not significant for either substance.

CONCLUSIONS

Externalizing behavior is one pathway from childhood maltreatment to age of substance use initiation. Services for maltreated youth should incorporate substance use prevention, particularly among those with early externalizing problems.

Working memory capacity and addiction treatment outcomes in adolescents

BACKGROUND

Brief addiction treatments including motivational interviewing (MI) have shown promise with adolescents, but the factors that influence treatment efficacy in this population remain unknown. One candidate is working memory, the ability to hold a fact or thought in mind. This is relevant, as in therapy, a client must maintain and manipulate ideas while working with a clinician. Working memory depends upon brain structures and functions that change markedly during neurodevelopment and that can be negatively impacted by substance use.

OBJECTIVES

In a secondary analysis of data from a clinical trial for adolescent substance use comparing alcohol/marijuana education and MI, we evaluated the relationship between working memory and three-month treatment-outcomes with the hypothesis that the relationship between intervention conditions and outcome would be moderated by working memory.

METHODS

With a diverse sample of adolescents currently using alcohol and/or marijuana (N = 153, 64.7% male, 70.6% Hispanic), we examined the relationship between baseline measures of working memory and alcohol and cannabis-related problem scores measured at the three-month follow-up.

RESULTS

The results showed that lower working memory scores were associated with poorer treatment response only for alcohol use, and only within the education group. No relationship was found between working memory and treatment outcomes in the MI group.

CONCLUSION

The results suggest that issues with working memory capacity may interfere with adolescents' ability to process and implement didactic alcohol and marijuana content in standard education interventions. These results also suggest that MI can be implemented equally effectively across the range of working memory functioning in youth.

Changes in Substance Use Symptoms Across Adolescence in Youth Perinatally Infected with HIV

The paper utilizes data collected at three time points in a longitudinal study of perinatally HIV-infected (PHIV+) and a comparison group of perinatally exposed but HIV-uninfected (PHEU) youths in the United States (N = 325). Using growth curve modeling, the paper examines changes in substance use symptoms among PHIV+ and PHEU youths as they transition through adolescence, and assesses the individual and contextual factors associated with the rate of change in substance use symptoms. Findings indicate that substance use symptoms increased over time among PHIV+ youths, but not among PHEU youths. The rate of change in these symptoms was positively associated with an increasing number of negative life events. Study findings underscore the need for early, targeted interventions for PHIV+ youths, and interventions to reduce adversities and their deleterious effects in vulnerable populations.

Screening for substance use and mental health problems in a cross-sectoral sample of Canadian youth

Background

This project examines the substance use and mental health concerns of a cross-sectoral, national, service-seeking sample of adolescents and emerging adults using an extended version of the Global Appraisal of Individual Needs-Short Screener (GSS). It also aims to provide incremental evidence of the psychometric properties of the GSS.

Methods

A sample of 2313 youth aged 12–24 years who presented for service participated in the project. Youth were recruited from 89 participating services across Canada representing eight major clinical and non-clinical sectors. Participants completed the GSS and provided sociodemographic data.

Results

The majority of youth presenting for services endorsed concerns on the GSS and would be likely to meet diagnostic criteria for a disorder in a full diagnostic assessment according to the norms for the scale, while many endorsed multiple concerns. This was true in both clinical and non-clinical settings. Externalizing concerns and suicidality were significantly more common in younger participants, while substance use was significantly more common in older youth. Females were more likely to endorse internalizing and suicidality concerns, while males endorsed more substance use and crime/violence concerns. Internalizing and suicidality concerns were also more common in Canada’s northerly regions. The reliability of the GSS was confirmed, however the factor structure revealed problems.

Conclusions

Youth presenting across clinical and non-clinical service sectors endorse high levels of need, supporting the importance of universal, cross-sectoral screening. The GSS is a practical tool that service providers across sectors can employ to identify the addiction and mental health service needs of youth, although further psychometric work is warranted. Implications for screening and treatment in community contexts are discussed.

Substance Use among Youth with Currently and Formerly Incarcerated Parents

Parental incarceration impacts millions of children in the U.S. and has important consequences for youths' adjustment. Children of incarcerated parents are at risk for a host of negative psychosocial outcomes, including substance abuse problems. Using data from a statewide survey of youth behavior, the effect of both present and past parental incarceration on youths' report of their substance use behaviors was examined. Both present and past parental incarceration was significantly associated with use of alcohol, tobacco, marijuana, and prescription drugs, as well as substance abuse and dependence. Implications for practice and research are discussed.

Social Ecological Determinants of Substance Use Treatment Entry Among Serious Juvenile Offenders From Adolescence Through Emerging Adulthood

PURPOSE

To examine the social-ecological determinants of substance use treatment entry among serious juvenile offenders over a 7 year period. Using the social-ecological framework, relevant predictors of substance use from the literature were used to assess risk (and protective) factors at the individual, parental, peer and neighborhood level.

METHOD

Serious juvenile offenders (N=1354, M_{age baseline}=16.0 years, SD=1.14) were prospectively followed over 7 years (M_{age Conclusion}=23.0 years, SD=1.15). Cox regression with time invariant and time varying predictors was used to predict time to first substance use treatment entry.

RESULTS

Results for each dimension, separately, varied slightly from the full model. In the full model peer delinquency, peer arrests, post-traumatic stress disorder (PTSD), impulse control, temperament, and emotional regulation remained salient risk (and protective) factors for treatment entry.

CONCLUSION

Associating with more deviant peers and having more of your peers arrested over the 7 year study period was associated with substantial increase in time to treatment entry. Furthermore, one of the strongest risk factors for treatment entry was a PTSD diagnosis. Treatment implications are discussed regarding peer affiliation and PTSD symptomology as well as potential neurological and biological contributors to increased risk for treatment entry.

The longitudinal associations between substance use, crime, and social risk among emerging adults: A longitudinal within and between-person latent variables analysis

BACKGROUND

The reciprocal relationship between crime and substance use is well known. However, when examining this relationship, no study to date has disaggregated between- and within-person effects, which represents a more methodologically sound and developmentally-appropriate analytic approach. Further, few studies have considered the role of social risk (e.g., deviant peers, high-risk living situations) in the aforementioned relationship. We examined these associations in a group of individuals with heightened vulnerability to substance use, crime and social risk: emerging adults (aged 18-25 years) in substance use treatment.

METHODS

Participants were 3479 emerging adults who had entered treatment. We used auto-regressive latent growth models with structured residuals (ALT-SR) to examine the within-person cross-lagged association between crime and substance use and whether social risk contributed to this association. A taxonomy of nested models was used to determine the structural form of the data, within-person cross-lagged associations, and between-person associations.

RESULTS

In contrast to the extant literature on cross-lagged relations between crime and substance use, we found little evidence of such relations once between- and within-person relations were plausibly disaggregated. Yet, our results indicated that within-person increases in social risk were predictive of subsequent increases in crime and substance use. Post-hoc analyses revealed a mediation effect of social risk between crime and substance use.

CONCLUSIONS

Findings suggest the need to re-think the association between crime and substance use among emerging adults. Individuals that remain connected to high-risk social environments after finishing treatment may represent a group that could use more specialized, tailored treatments.

Decreasing Risk Factors for Later Alcohol Use and Antisocial Behaviors in Children in Foster Care by Increasing Early Promotive Factors

Children in foster care are at high risk for poor psychosocial outcomes, including school failure, alcohol and other substance abuse, and criminal behaviors. Promoting healthy development by increasing broad-impact positive skills may help reduce some of the risk factors for longer-term negative outcomes. School readiness has been linked to a number of positive outcomes across childhood, adolescence, and adulthood, and may also boost intermediary positive skills such as self-competence. This paper presents findings from a longitudinal study involving 192 children in foster care who were 5 years old at the start of the study. They participated in a randomized controlled trial of a school readiness program to prepare them for kindergarten. Outcomes were assessed at third grade (9 years old) on variables associated with risk for later involvement in substance use and delinquency. These included positive attitudes towards alcohol use, positive attitudes towards antisocial behaviors, and involvement with deviant peers. Results showed that the intervention decreased positive attitudes towards alcohol use and antisocial behaviors. Further, the mediating role of children's self-competence was tested. The intervention positively influenced children's third-grade self-competence, which in turn, decreased their involvement with deviant peers. Findings suggest that promoting school readiness in children in foster care can have far-reaching, positive effects and that increased self-competence may be a mechanism for reducing risk.

Juvenile Justice-Translational Research on Interventions for Adolescents in the Legal System (JJ-TRIALS): a cluster randomized trial targeting system-wide improvement in substance use services

Background

The purpose of this paper is to describe the Juvenile Justice—Translational Research on Interventions for Adolescents in the Legal System (JJ-TRIALS) study, a cooperative implementation science initiative involving the National Institute on Drug Abuse, six research centers, a coordinating center, and Juvenile Justice Partners representing seven US states. While the pooling of resources across centers enables a robust implementation study design involving 36 juvenile justice agencies and their behavioral health partner agencies, co-producing a study protocol that has potential to advance implementation science, meets the needs of all constituencies (funding agency, researchers, partners, study sites), and can be implemented with fidelity across the cooperative can be challenging. This paper describes (a) the study background and rationale, including the juvenile justice context and best practices for substance use disorders, (b) the selection and use of an implementation science framework to guide study design and inform selection of implementation components, and (c) the specific study design elements, including research questions, implementation interventions, measurement, and analytic plan.

Methods/design

The JJ-TRIALS primary study uses a head-to-head cluster randomized trial with a phased rollout to evaluate the differential effectiveness of two conditions (Core and Enhanced) in 36 sites located in seven states. A Core strategy for promoting change is compared to an Enhanced strategy that incorporates all core strategies plus active facilitation. Target outcomes include improvements in evidence-based screening, assessment, and linkage to substance use treatment.

Discussion

Contributions to implementation science are discussed as well as challenges associated with designing and deploying a complex, collaborative project.

Plasticity of risky decision making among maltreated adolescents: Evidence from a randomized controlled trial

Childhood maltreatment has lasting negative effects throughout the life span. Early intervention research has demonstrated that these effects can be remediated through skill-based, family-centered interventions. However, less is known about plasticity during adolescence, and whether interventions are effective many years after children experience maltreatment. This study investigated this question by examining adolescent girls' ability to make advantageous decisions in the face of risk using a validated decision-making task; performance on this task has been associated with key neural regions involved in affective processing and executive functioning. Maltreated foster girls (n = 92), randomly assigned at age 11 to either an intervention designed to prevent risk-taking behaviors or services as usual (SAU), and nonmaltreated age and socioeconomic status matched girls living with their biological parent(s) (n = 80) completed a decision-making task (at age 15-17) that assessed risk taking and sensitivity to expected value, an index of advantageous decision making. Girls in the SAU condition demonstrated the greatest decision-making difficulties, primarily for risks to avoid losses. In the SAU group, frequency of neglect was related to greater difficulties in this area. Girls in the intervention condition with less neglect performed similarly to nonmaltreated peers. This research suggests that early maltreatment may impact decision-making abilities into adolescence and that enriched environments during early adolescence provide a window of plasticity that may ameliorate these negative effects.

Brief report: Growth in polysubstance use among youth in the child welfare system

PURPOSE

This paper establishes foundational knowledge on development of polysubstance use among adolescents in the U.S. child welfare system (CWS).

METHOD

Data on U.S. CWS adolescents from the National Study of Child and Adolescent Well-Being were examined for rates of alcohol, marijuana, and hard drug use; and change in use over time.

RESULTS

Past 30-day absolute use was highest for alcohol, but daily/near-daily use highest for marijuana. Marijuana use increased at later time points. A correlated growth model suggested covariation in use of the substances. A curve-of-factors model suggested that higher-order factors explain most variation in substance use, except at the last time point. Those with lower use changed the most across time.

CONCLUSIONS

Subsequent research among CWS adolescents in the U.S. should consider substances jointly. Prevention should focus on marijuana, and later periods of adolescence and CWS involvement. Youth not thought of as at great risk upon entering the CWS may be most vulnerable.

Differences in polysubstance use among youth in the child welfare system: toward a better understanding of the highest-risk teens

The current study extended limited prior work on polysubstance use among youth in the child welfare system (CWS) by addressing their potentially greater risk of engaging in polysubstance use, the causes of interpersonal variation in use, and changes in use over time, particularly at later points of involvement in the CWS. Using longitudinal data from the National Survey of Child and Adolescent Well-Being (n=1,178), a series of time-invariant and time-varying demographic and contextual factors were explored to assess their role both overall and at unique points of involvement in the CWS. A series of unconditional and conditional curve-of-factor models were estimated and results indicated that time-invariant characteristics of ethnicity and gender were not related to polysubstance use. Time-variant characteristics of age and placement were associated with polysubstance use and highlighted the dynamic nature of age as a risk factor. Out-of-home placement was protective against later substance use for youth who had been removed from contexts with their original caretaker where there were higher levels of reported violence. Our results suggest that in the child welfare population, the modeling of multiple substances rather than a single substance in isolation is more informative because it yields information on the confluence of behaviors that tend to occur and evolve together.

Prevalence and comorbidity of mental disorders among adolescents living in residential youth care

Most adolescents are placed in residential youth care (RYC) because of severe psychosocial strains and child maltreatment, which represent risk factors for developing mental disorders. To plan RYC units and ensure that residents receive evidence-based psychiatric interventions, it is necessary to obtain reliable and valid prevalence estimates of mental disorders in this population. However, there is a lacuna of research on diagnoses derived from standardized clinical interviews. The aim of this study was to assess the prevalence and comorbidity of mental disorders applying diagnostic interviews in an entire population of adolescents living in RYC in Norway. All young people in RYC were invited to participate in the study. Eighty-six RYC institutions with 601 eligible adolescents were included and 400 adolescents, 12-20 years old, participated in the study, yielding a response rate of 67 %. Anonymous Child Behaviour Checklist scores for 141 (70 %) of the declining residents were also available, allowing diagnoses according to the Diagnostic and Statistical Manual of Mental Disorders Fourth Edition (DSM-IV) for 541 youths to be estimated. Diagnoses were assessed by trained interviewers with the Child and Adolescent Psychiatric Assessment interview (CAPA). Seventy-six point two per cent (71.5-80.8 CI 95 %) of adolescents received at least one 3-month DSM-IV diagnosis. Prevalence rates for internalizing psychiatric disorders were higher than for behavioural disorders. Comorbidity was high between these two groups. Mental disorders were prevalent among children and youth in RYC. Our results create major concerns and challenge the existing organization of the RYC system.

Program manager perspectives on the service system to meet the needs of youth with concurrent disorders: findings from a Canadian national survey

Background

Concurrent mental health and substance use issues are a serious problem for adolescents and transition-aged youth. Service providers across sectors must be involved in informing system change to meet youth needs. This study examines stakeholder perspectives on services for youth with concurrent disorders including 1) clinical issues in youth services; 2) priority system issues; and 3) optimal knowledge translation strategies to enhance researcher-stakeholder communication.

Methods

A database of youth clinical services across Canada was developed. Program managers (n = 481) at cross-sectoral (mental health, addictions, justice, child welfare, advocacy, and outreach) youth-serving (aged 12–24) programs were invited to complete an online survey; 232 responded. Survey questions concerned youth needs, program characteristics, priorities for service system enhancement; and usual and preferred knowledge translation methods.

Results

Across service sectors, the mean estimated proportion of youth using services with concurrent mental health and substance use problems was 55 %. Program managers reported routine screening for mental health and substance use concerns (66 %), referring to other agencies to meet the concurrent disorder needs of youth (54 %), offering specific programming for concurrent disorders (42 %), and program evaluation (48 %). Notably, mental health programs were significantly less likely to offer concurrent disorders services than addictions programs. Where services do exist, most are targeted at youth aged 12–18 years, with fewer services available for transition-aged youth. Endorsement of various system change goals exceeded 80 %, with a particular emphasis on improving access to services (49 %), ensuring a continuum of services for varying levels of severity (37 %), and improved integration across sectors (36 %). Preferred knowledge exchange methods were workshops and websites for receiving information; and focus groups or surveys, rather than intensive participation on research teams, to inform research.

Conclusions

There is a high need to build capacity across most sectors for meeting the needs of youth with co-occurring mental health and substance use problems, especially for transition-aged youth. In addition, limits in program evaluation should be addressed. Innovative knowledge exchange strategies are needed to better meet the needs of youth with concurrent disorders. Although service providers expressed readiness to participate in service enhancement and knowledge translation activities, effective, feasible approaches must integrate strategies likely to result in desired clinical outcomes, given clinical workload challenges.

Which matters most? Demographic, neuropsychological, personality, and situational factors in long-term marijuana and alcohol trajectories for justice-involved male youth

Justice-involved youth have high rates of alcohol and marijuana use. However, little is known about what may drive these rates over time. Using a large-scale (N = 1,056; 41.4% African American, 33.5% Hispanic) longitudinal study with strong retention (M retention = 90% over Years 1-7), we utilized random-effects regression to determine the comparative contribution of four sets of factors in justice-involved males' patterns of marijuana and heavy alcohol use (number of times drunk) over 7 years of follow-up: demographic, personality, situational, and neuropsychological factors. Across both marijuana and heavy alcohol use models, three factors were particularly strong contributors to lower rates of substance use: (a) Hispanic ethnicity, (b) less exposure (street) time, and (c) better impulse control. Similarly, two factors were strong contributors to increased rates of marijuana and heavy alcohol use: (a) delinquent peers and (b) family member arrest. Together, these findings indicate the relative superiority of these independent variables over other categories (i.e., neuropsychological factors) in predicting high-risk youths' long-term (7-year) rates of substance use. These findings also suggest the importance of evaluating the connection of these areas for high-risk, adjudicated youth.

Do therapist behaviors differ with Hispanic youth? A brief look at within-session therapist behaviors and youth treatment response

Brief addiction treatments, including motivational interviewing (MI), have shown promise with youth. One underexamined factor in this equation is the role of therapist behaviors. We therefore sought to assess whether and how therapist behaviors differ for Hispanic versus non-Hispanic youth and how that may be related to treatment outcome. With 80 substance-using adolescents (M age = 16 years; 65% male; 59% Hispanic; 41% non-Hispanic), we examined the relationship between youth ethnicity and therapist behaviors across two brief treatments (MI and alcohol/marijuana education [AME]). We then explored relationships to youth 3-month treatment response across four target outcomes: binge drinking days, alcohol-related problems, marijuana use days, and marijuana-related problems. In this study, therapists showed significantly more MI skills within the MI condition and more didactic skills in the AME condition. With respect to youth ethnicity, across both conditions (MI and AME), therapists used less MI skills with Hispanic youth. Contrary to expectations, therapists' use of MI skills was not connected to poorer outcomes for Hispanic youth across the board (e.g., for binge drinking days, marijuana use days, or marijuana-related problems). Rather, for Hispanic youth, therapists' use of lower MI skills was related only to poorer treatment outcomes in the context of alcohol-related problems. The observed relationships highlight the importance of investigating salient treatment interactions between therapist factors and youth ethnicity to guide improvements in youth treatment response.

A randomized clinical trial of family therapy in juvenile drug court

The objective of this article is to examine the effectiveness of 2 theoretically different treatments delivered in juvenile drug court--family therapy represented by multidimensional family therapy (MDFT) and group-based treatment represented by adolescent group therapy (AGT)--on offending and substance use. Intent-to-treat sample included 112 youth enrolled in juvenile drug court (primarily male [88%], and Hispanic [59%] or African American [35%]), average age 16.1 years, randomly assigned to either family therapy (n = 55) or group therapy (n = 57). Participants were assessed at baseline and 6, 12, 18 and 24 months following baseline. During the drug court phase, youth in both treatments showed significant reduction in delinquency (average d = .51), externalizing symptoms (average d = 2.32), rearrests (average d = 1.22), and substance use (average d = 4.42). During the 24-month follow-up, family therapy evidenced greater maintenance of treatment gains than group-based treatment for externalizing symptoms (d = 0.39), commission of serious crimes (d = .38), and felony arrests (d = .96). There was no significant difference between the treatments with respect to substance use or misdemeanor arrests. The results suggest that family therapy enhances juvenile drug court outcomes beyond what can be achieved with a nonfamily based treatment, especially with respect to what is arguably the primary objective of juvenile drug courts: reducing criminal behavior and rearrests. More research is needed on the effectiveness of juvenile drug courts generally and on whether treatment type and family involvement influence outcomes.

Exploration of the (Interrater) Reliability and Latent Factor Structure of the Alcohol Use Disorders Identification Test (AUDIT) and the Drug Use Disorders Identification Test (DUDIT) in a Sample of Dutch Probationers

BACKGROUND

The use of brief, reliable, valid, and practical measures of substance use is critical for conducting individual (risk and need) assessments in probation practice. In this exploratory study, the basic psychometric properties of the Alcohol Use Disorders Identification Test (AUDIT) and the Drug Use Disorders Identification Test (DUDIT) are evaluated.

METHODS

The instruments were administered as an oral interview instead of a self-report questionnaire. The sample comprised 383 offenders (339 men, 44 women). A subset of 56 offenders (49 men, 7 women) participated in the interrater reliability study. Data collection took place between September 2011 and November 2012.

RESULTS

Overall, both instruments have acceptable levels of interrater reliability for total scores and acceptable to good interrater reliabilities for most of the individual items. Confirmatory factor analyses (CFA) indicated that the a priori one-, two- and three-factor solutions for the AUDIT did not fit the observed data very well. Principal axis factoring (PAF) supported a two-factor solution for the AUDIT that included a level of alcohol consumption/consequences factor (Factor 1) and a dependence factor (Factor 2), with both factors explaining substantial variance in AUDIT scores. For the DUDIT, CFA and PAF suggest that a one-factor solution is the preferred model (accounting for 62.61% of total variance).

CONCLUSIONS

The Dutch language versions of the AUDIT and the DUDIT are reliable screening instruments for use with probationers and both instruments can be reliably administered by probation officers in probation practice. However, future research on concurrent and predictive validity is warranted.

Effectiveness of the Treatment Readiness and Induction Program for increasing adolescent motivation for change

Success in substance abuse treatment is improved by problem recognition, desire to seek help, and readiness to engage in treatment, all of which are important aspects of motivation. Interventions that facilitate these at treatment induction for adolescents are especially needed. The purpose of this study is to assess the effectiveness of TRIP (Treatment Readiness and Induction Program) in promoting treatment motivation. Data represent 519 adolescents from 6 residential programs who completed assessments at treatment intake (time 1) and 35 days after admission (time 2). The design consisted of a comparison sample (n=281) that had enrolled in treatment prior to implementation of TRIP (standard operating practice) and a sample of clients that had entered treatment after TRIP began and received standard operating practice enhanced by TRIP (n=238). Repeated measures ANCOVAs were conducted using each time 2 motivation scale as a dependent measure. Motivation scales were conceptualized as representing sequential stages of change. LISREL was used to test a structural model involving TRIP participation, gender, drug use severity, juvenile justice involvement, age, race-ethnicity, prior treatment, and urgency as predictors of the stages of treatment motivation. Compared to standard practice, adolescents receiving TRIP demonstrated greater gains in problem recognition, even after controlling for the other variables in the model. The model fit was adequate, with TRIP directly affecting problem recognition and indirectly affecting later stages of change (desire for help and treatment readiness). Future studies should examine which specific components of TRIP affect change in motivation.

Evidence base on outpatient behavioral treatments for adolescent substance use: updates and recommendations 2007-2013

This article updates the evidence base on outpatient behavioral treatments for adolescent substance use (ASU) since publication of the previous review completed for this journal by Waldron and Turner ( 2008 ). It first summarizes the Waldron and Turner findings as well as those from more recent literature reviews and meta-analytic studies of ASU treatment. It then presents study design and methods criteria used to select 19 comparative studies subjected to Journal of Clinical Child & Adolescent Psychology level of support evaluation. These 19 studies are grouped by study category (efficacy or effectiveness) and described for sample characteristics, methodological quality, and substance use outcomes. Cumulative level of support designations are then made for each identified treatment approach: ecological family-based treatment, group cognitive-behavioral therapy, and individual cognitive-behavioral therapy are deemed Well Established; behavioral family-based treatment and motivational interviewing are deemed Probably Efficacious; drug counseling is deemed Possibly Efficacious; and four integrated treatment models combining more than one approach are deemed Well Established or Probably Efficacious. The remainder of the article (a) articulates fidelity, mediator, and moderator effects reported for evidence-based approaches since 2008 and (b) recommends four enhancements to the prevailing business model of ASU outpatient services to accelerate penetration of evidence-based approaches into the underserved consumer base: pursue partnerships with influential governmental systems, utilize web-based technology to extend reach and control costs, adapt effective methods for linking services across sectors of care, and promote uptake and sustainability by emphasizing return on investment.

Understanding the elevated risk of substance use by adolescents in special education and residential youth care: the role of individual, family and peer factors

Adolescents who attend special education for behavioural problems (SEB) and adolescents who live in a residential youth care institution (RYC) are characterised by behavioural disorders and problematic family backgrounds and have an increased risk for substance use. Though it is likely that the high rates of substance use in SEB/RYC settings might be inherent to the risk profile of these adolescents, little is known about the actual role the risk profile has in explaining substance use. The present study examined the extent to which the elevated risk of substance use in SEB/RYC can be explained by high levels of individual, family, and peer risk indicators that are known to characterise their risk profile. Self-report questionnaires from 531 adolescents in RYC (50 % male; mean age 14.7) and 603 adolescents in SEB (81 % male; mean age 14.1) were compared with information from 1,905 adolescents attending special education for students with learning disabilities (SEL) (56 % male; mean age 14.1). Results show that adolescents in SEB/RYC reported higher levels of daily smoking, weekly alcohol consumption, cannabis and hard drug use, as well as greater prevalence of individual, family and peer factors. Though individual, family and in particular peer risk indicators all explain some of the variance in substance use, the differences between adolescents in SEB/RYC compared with SEL remained significant and substantial, with the exception of heavy alcohol consumption. These findings suggest that deviant peer affiliation, in particular, plays a role in explaining high substance use levels in SEB/RYC and those factors relevant to the residential settings and special education schools might also contribute to substance use in these high-risk groups.

Cortical Volume Alterations in Conduct Disordered Adolescents with and without Bipolar Disorder

Background: There is increasing evidence that bipolar disorder (BD) and conduct disorder (CD) are co-occurring disorders. Magnetic resonance imaging has revealed differences in the structure and function of the frontal cortex in these disorders when studied separately; however, the impact of BD comorbidity on brain structure in adolescents with CD has not yet been examined. Method: We conducted an optimized voxel based morphometry (VBM) study of juvenile offenders with the following diagnoses: conduct disorder with comorbid bipolar disorder (CD-BD; n = 24), conduct disorder without bipolar disorder (CD; n = 24) and healthy controls (HC, n = 24). Participants were 13–17 years of age, in a residential treatment facility for repeat offenders. The three groups in this study were similar in age, gender, socioeconomic status and ethnicity. Results: We found CD-BD subjects had decreased volume relative to controls at the voxel level in the right medial prefrontal cortex (PFC). Using a Threshold-Free Cluster Enhancement (TFCE) technique, the CD-BD subjects had significantly decreased volumes of the right medial prefrontal cortex and portions of the superior and inferior frontal gyrus, anterior cingulate and temporal gyrus. The CD subjects did not have differences in brain volume compared to control subjects or CD-BD subjects. Conclusions: Our findings suggest the comorbidity between CD and BD is associated with neurobiological impact namely volumetric differences from healthy controls. Furthermore subjects with this comorbidity had poorer lifetime functioning, more mood and attentional dysfunction, and more medication exposure than subjects with CD who were not BD.

Delinquency, depression, and substance use disorder among child welfare-involved adolescent females

Although adolescents with delinquency are known to have higher-than-average rates of depression or substance use disorder (SUD), research on the topic is inconsistent. It remains unclear weather depression or SUD leads to delinquency, whether delinquency leads to depression or SUD, or whether there is bi-directionality. Utilizing the National Survey of Child and Adolescent Well-Being (Wave I: 2008-2009; Wave II: 18 months later: N=5872), we used logistic regression to predict depression from delinquency (and vice versa), and SUD from delinquency (and vice versa). After inclusion of control variables, we found that females with minor theft in Wave I were more than 4 times as likely (adjusted odds ratio [aOR]=4.34; 95% CI: 1.10-17.16) as females without minor theft to be depressed in Wave II, and those with public disorder in Wave I were almost 3 times as likely (aOR=2.74; 95% CI: 1.03-7.30) as those without public disorder to have SUD in Wave II. Overall delinquency also predicted depression or SUD, and SUD predicted delinquency. Practitioners could address risk for depression or SUD among child welfare-involved adolescent females by focusing on overall delinquency or on specific types of delinquency (minor theft for depression and public disorder for SUD) and by offering interventions (e.g., cognitive-behavioral psychotherapy) that have been shown to be effective in preventing depression or SUD. In addition, with respect to our finding that SUD predicts delinquency among adolescent females, practitioners can help prevent delinquency by offering interventions (e.g., intensive outpatient treatments) that have well documented effectiveness in addressing SUD.

Continued detention involvement and adolescent marijuana use trajectories

Justice-involved youth have high rates of marijuana use. Less is known about what may drive these rates, particularly when justice-involved youth return to the community. One factor that has been implicated is continued detention involvement. Yet, it is unknown how this factor may influence marijuana use trajectories. Using longitudinal growth curve modeling, the researchers evaluated the association between continued detention involvement and marijuana use trajectories in two large, ethnically diverse samples of community-based, justice-involved youth. Across both samples, marijuana use decreased over time for youth with continued detention involvement but did not change for youth without continued detention involvement. These findings underscore the importance of attending to the influence of detention involvement in community-based, justice-involved adolescents' marijuana use trajectories. This study also highlights the importance of coordinating prevention/intervention programming for justice-involved youth once they are in the community.

Higher rates of adolescent substance use in child welfare versus community populations in the United States

OBJECTIVE

Youth substance use exacts costly consequences for a variety of important health outcomes. We examined and compared prevalence rates and a common set of psychosocial factors of lifetime and current substance use among child welfare-involved youths and community youths from two nationally representative data sets.

METHOD

Using the National Survey of Child and Adolescent Well-Being and the National Longitudinal Study of Adolescent Health, we compared prevalence rates and conducted logistic regression models for eight binary outcome measures of substance use: lifetime and current use of alcohol, inhalant, marijuana, and other illicit drugs to examine predictors of substance involvement in the two samples.

RESULTS

Substance use prevalence was higher among child welfare-involved youths than community youths for lifetime marijuana use, lifetime and current inhalant use, and lifetime and current other illicit drug use. Among both child welfare-involved and community youths, delinquency was the factor most strongly associated with all lifetime substance use outcomes. Notably, family structure and parental closeness were important protective factors against current substance use among child welfare-involved youths. For community youths, poorer emotional health was the strongest indicator of current substance use.

CONCLUSIONS

Substance use among all adolescents is a critical public health concern. Given the heightened vulnerability of child welfare-involved youths, it is particularly important to focus prevention and early intervention efforts on this population. Further research should explore additional factors associated with substance use among these youths so that child welfare and behavioral health systems may jointly target prevention and intervention efforts.
