Homelessness and Food Insecurity During Emerging Adulthood: Associations With Changes in Behavioral and Physical Health Over a Two-Year Period

PURPOSE

For emerging adults in the United States, economic instability is a widespread problem with implications for the successful transition to adulthood. This study examines how two indicators of economic instability, homelessness and food insecurity, are associated with changes in health-related outcomes over a two-year period.

METHODS

The analytic sample (N = 2,182) completed online surveys in 2019-2020 (mean age 23 years) and 2021-2022 (mean age 25 years). Regression analyses were conducted for the full sample, as well as by sexual or gender diverse (SGD) identity (17.8% of sample identified as SGD) and race/ethnicity (76.3% identified as non-White).

RESULTS

At age 23, 8.2% of participants reported homelessness and 31.2% reported food insecurity. In the full sample, homelessness and food insecurity were associated with increased depression, anxiety, physical ailments, and drug problems two years later. A similar pattern emerged for those identifying as non-SGD. The only associations for SGD-identifying participants were food insecurity with increased anxiety, depression, and physical ailments. Racial/ethnic differences indicated that homelessness was associated with increased depression and anxiety among Hispanics, and physical ailments and drug consequences among Asians, but fewer drug problems among Whites. Food insecurity was associated with increased depression in all racial/ethnic groups, anxiety among Hispanics and Asians, physical ailments among Whites and Asians, and drug problems among Asians.

DISCUSSION

Homelessness and food insecurity predicted worse health outcomes during the transition to adulthood, with varying results across SGD and racial/ethnic subgroups. It is important for future research to continue examining long-term effects of economic instability on health disparities during this important developmental period.

Longitudinal associations among experiences of sexual assault, posttraumatic stress disorder symptoms, and heavy drinking in young adults

Prior research with young adults has demonstrated clear associations between experiences of sexual assault, symptoms of posttraumatic stress disorder (PTSD), and alcohol use, but most studies have been cross-sectional or have not considered multiple theoretical pathways to understand these associations. Using six waves of data from a longitudinal cohort sample of 1,719 young adults, we examined associations among experiences of past-year sexual assault (i.e., rape, unwanted sexual touching, and physical intimidation in a sexual way), PTSD symptoms, and the frequency of binge drinking over time, allowing for the exploration of symptom-induced, interpersonal risk, and substance-induced pathways for male and female participants. For both male, βs = 2.84 to 6.55, and female participants, βs = 2.96 to 10.1, higher prior levels of PTSD symptoms were associated with larger increases in binge drinking over time. For female participants, higher prior levels of sexual assault were associated with larger increases in PTSD symptoms over time, βs = 3.48 to 4.25, whereas for male participants, higher prior levels of past-year binge drinking were associated with decreases in PTSD symptoms over time, βs = -2.75 to -0.53. Continued efforts are needed to prevent sexual assault among young adults and address PTSD symptoms among those who experience sexual assault. Interventions that target binge drinking are also needed for individuals who experience PTSD symptoms, especially young adults, to address potentially hazardous drinking before problems escalate and become chronic.

Sociodemographic and Behavioral Risk Correlates of PrEP Interest and Use Among Young Adults Experiencing Homelessness in Los Angeles

Young adults experiencing homelessness (YAEH) are at elevated risk for HIV compared to their stably housed peers. Preexposure prophylaxis (PrEP) is highly effective at preventing HIV infection, yet YAEH have been largely overlooked in PrEP efforts to date despite YAEH reporting high overall interest in PrEP. We assessed individual, social, and structural variables associated with PrEP interest and use among a sample of 195 YAEH (ages 18-25) recruited from drop-in centers across Los Angeles County who met criteria for HIV risk. In the current sample, though most had heard of PrEP (81.0%), the majority were not interested in taking PrEP (68.2%) and only a minority had used/were using PrEP (11.8%). YAEH who identified as sexual and/or gender minority, reported knowing someone who had used PrEP, or recently accessed sexual health services were more likely to have used and/or reported interest in using PrEP. Those who reported more episodes of heavy drinking were less likely to report having used PrEP. Suggestions are provided for better integrating PrEP-related services into existing behavioral and health service programs for YAEH, as well as leveraging peers and fostering positive social norms to reduce PrEP-related stigma and increase interest and use of PrEP among YAEH.

Sober Curiosity and Participation in Temporary Alcohol Abstinence Challenges in a Cohort of U.S. Emerging Adults

OBJECTIVE

Thus far, behavioral health research in the United States has not explored the prevalence or correlates of sober curiosity (SC; exploratory or experimental abstinence or moderation) or temporary alcohol abstinence challenges (TAACs; e.g., "Dry January"), despite significant attention in media and popular discourse. We explored these activities in a sample of U.S. emerging adults (e.g., ages 18-29), a population with higher-risk drinking behavior yet some of the lowest rates of treatment engagement for alcohol use problems.

METHOD

Survey data were collected in 2021-2022 among participants (n = 1,659; M age = 24.7 years). We assessed SC awareness/engagement and past-year TAAC participation, and differences across demographics and behavioral characteristics.

RESULTS

Overall, 9% of emerging adults were familiar with SC and 7% had participated in a TAAC in the past year. Half of TAAC participants reported drinking less after the TAAC, and 15% remained abstinent after the TAAC ended. SC familiarity and TAAC were both associated with past-month heavy drinking, cannabis use, higher Alcohol Use Disorders Identification Test (AUDIT) scores, more past-year alcohol and cannabis consequences, past-year substance use treatment, and greater readiness to quit alcohol.

CONCLUSIONS

Both SC and TAACs may have potential to engage young people with a desire to moderate or eliminate their alcohol consumption. This may occur directly through use of these strategies or by helping them connect to additional services. Future research can help the field understand the uptake of SC and TAACs, gauge efficacy, and identify avenues to link young people to resources and interventions.

Trajectories of alcohol and cannabis use among emerging adults with a history of unstable housing: Associations with functioning over a two-year period

INTRODUCTION

Research has documented high rates of alcohol and cannabis use among emerging adults experiencing homelessness. However, little is known about trajectories of use over time or how trajectories are associated with functioning (e.g., risk behaviors, mental and physical health, social functioning, economic well-being).

METHODS

Data come from a cohort of 18-25 year olds experiencing homelessness who were surveyed 5 times over 24 months. Parallel process growth mixture models were used to model heterogeneity in alcohol and cannabis use across the 5 timepoints, which allowed for the extraction of classes based on both alcohol and cannabis use trajectories. Classes were compared on demographics and functioning at baseline and 24-months.

RESULTS

Two trajectory classes of alcohol and cannabis use emerged: moderate decreasing cannabis and low stable alcohol use (75% of the sample) and heavy cannabis and alcohol use (25% of the sample). The heavy cannabis and alcohol use class reported a significantly higher likelihood for any non-cannabis drug use at baseline and 24-months, as well as greater depression and physical ailments at 24-months. In addition, at 24-months this class had a marginally higher likelihood of a positive screen for at least moderate anxiety and being recently unhoused.

CONCLUSIONS

The effects of heavy continued cannabis and alcohol co-use on multiple domains of functioning (e.g., risk behavior, mental and physical health) highlight the importance of a coordinated systems approach that addresses the often complex and interrelated challenges facing emerging adults with a history of homelessness.

The Role of Social Networks on Depression and Anxiety Among a Sample of Urban American Indian/Alaska Native Emerging Adults

PURPOSE

Mental health inequalities continue to persist among American Indian/Alaska Native (AI/AN) people. However, few studies have examined the association of social networks and depression and anxiety among urban emerging AI/AN adults.

METHODS

This study analyzes the association of social network characteristics with depression and anxiety among a sample of urban AI/AN emerging adults. A second set of regression models tested the same associations but controlling for respondent sexual and gender minority (SGM) status. Data were from a sample of 150 AI/AN emerging adults residing in urban areas from 20 different states (86% female; mean age 21.8; 48.0% SGM) who participated in a randomized controlled trial analyzing the effects of culturally grounded interventions on alcohol and other drug use and cultural connectedness.

RESULTS

Participants with a higher proportion of network members who were around the same age reported significantly less anxiety. Those who had a higher proportion of network members who they sometimes/often argue/fight with were more likely to report greater depression and anxiety. Participants with higher proportions of social network members who have ever lived on a reservation/Rancheria/tribal land/tribal village reported significantly less depression. However, participants with higher proportions of social network members who lived 50 miles away or more reported significantly more depression. Controlling for SGM status, results were largely similar.

DISCUSSION

Results highlight the role of social connections on the mental well-being of urban AI/AN emerging adults.

Mixed Methods Evaluation of Satisfaction with Two Culturally Tailored Substance use Prevention Programs for American Indian/Alaska Native Emerging Adults

American Indian/Alaska Native (AI/AN) communities are disproportionately affected by the opioid epidemic. AI/AN emerging adults (ages 18-25) in urban areas are at particularly high risk, with the overdose death rate among urban-dwelling AI/AN people 1.4 times higher than rural-dwelling AI/AN people. Despite these challenges, there are no evidence-based culturally tailored prevention or intervention programs to address opioid, alcohol and other drug use among urban AI/AN emerging adults. This study focused on understanding AI/AN emerging adults' experiences with two culturally tailored programs addressing opioid, cannabis, and alcohol use as part of the randomized controlled trial for Traditions and Connections for Urban Native Americans (TACUNA) in order to enhance feasibility of this intervention. Using a convergent mixed methods design at 3-month follow-up, we collected satisfaction and experience ratings and written narratives (total n = 162; intervention n = 77; control n = 85) from a sample of urban-dwelling AI/AN emerging adults who participated in both programs. We analyzed data through simultaneous examination of qualitative and quantitative data. The quantitative ratings show that both programs were rated highly. The qualitative data contextualized these ratings, illustrating pathways through which specific components were perceived to cause desired or observed behavioral change in participants. Among the elements that mattered most to these participants were the convenience of the virtual format, having a comfortable and safe space to share personal stories, and learning new information about their social networks. Negative comments focused on workshop length and inconvenient scheduling. This is one of the first studies to explore participant satisfaction and experience with culturally tailored substance use programming among a historically marginalized and understudied population. It is important to consider the voices of urban-dwelling AI/AN people in program development because hidden factors, such as limited financial resources, limited time, and misalignment with cultural values may prevent existing programs from being feasible.

Bidirectional Associations Between Daily Sleep and Wake Behaviors in Urban American Indian/Alaska Native Youth

PURPOSE

This is the first study to examine daily, bidirectional associations between sleep and wake behaviors/mood in urban American Indian/Alaska Native (AI/AN) adolescents.

METHODS

Participants were 142 urban AI/AN adolescents (mean age = 14 years, 58% female). Sleep was measured with actigraphy (total sleep time [TST] and sleep efficiency) and daily diary (bedtime, wakeup time, and sleep quality) over seven consecutive days. Wake behaviors (caffeine consumption, physical activity, participation in cultural activities, and electronic use after 8p.m.) and mood upon awakening (higher rating indicates greater happiness) were measured via daily diary for seven consecutive days. Multilevel models examined the degree to which nightly sleep predicted next day's wake behaviors and, conversely, wake behaviors and mood predicted nightly sleep, controlling for age, gender, and weekday/weekend.

RESULTS

Earlier bedtime and wakeup times predicted greater participation in physical activity the following day. Later bedtime and wakeup time, worse sleep quality, and shorter TST predicted greater electronic use the following night. Earlier bedtime and wakeup time and better sleep quality predicted higher mood ratings. Conversely, greater caffeine consumption during the day predicted both later bedtime and wakeup time. Participation in cultural activities is predicted later bedtime. More nighttime electronic use predicted both later bedtime and wakeup time, poorer sleep quality, and worse TST and sleep efficiency. Higher mood ratings in the morning predicted earlier bedtime and later wakeup time.

DISCUSSION

Findings highlight dynamic associations between sleep and wake behaviors and mood in AI/AN adolescents and may elucidate novel pathways for intervention and future research.

Because We Love You (BeWeL): A protocol for a randomized controlled trial of two brief interventions focused on social and cultural connectedness to reduce risk for suicide and substance misuse in young Alaska Native people

Background

Suicide among young people in Alaska Native (AN) communities was nearly unheard of through the establishment of statehood in 1959, but in the 1970s, AN suicide rates began to double every five years, with most of the increase due to suicide among 15 to 25-year-olds. From 1960-1995, the suicide rate increased by approximately 500% during this period of rapid, imposed social transition. For example, families were forced to live in settlements and children were sent to boarding schools. These disruptions increased conditions associated with suicide risk (e.g., substance use disorders, cultural disconnection), and challenged the community-level social safety net of youth protective factors that might have moderated effects of these traumas. The present study addresses the significant gap in culturally appropriate evidence-based programming to address suicide prevention among AN young people as part of aftercare. Our key research questions and methodology have been informed by AN stakeholders, and the intervention approach is Indigenous-led.

Methods

Our interventions are targeted toward Alaska Native young people ages 14-24 who present with suicide attempt, ideation, or associated risk behaviors, including alcohol-related injury in the Yukon-Kuskokwim region or the Interior. In a randomized controlled trial, 14-24-year-old AN individuals will receive either BeWeL (n = 185), which comprises a 45-minute virtual cultural talk addressing family and ancestral strengths and increasing protective factors, or BeWeL plus motivational interviewing with social networks, which includes an additional 15 minutes focused on discussion of the individual's social networks (n = 185). We will evaluate intervention effects on primary outcomes of suicide-intent risk, depression, anxiety, frequency of alcohol use, and alcohol consequences. Some of our secondary outcomes include individual and community protective factors, social networks, and awareness of connectedness.

Discussion

This project has the potential to expand the range and effectiveness of suicide prevention services for AN young people and will help meet the need in Alaska to link clinical behavioral health services to AN community-based networks, and to engage local cultural resources in aftercare for individuals at risk for suicide. Findings have potential to provide practical information to advance the field of suicide prevention and enhance protective factors and resiliency among this population.

Predictors of Housing Trajectories Among Young Adults Experiencing Homelessness in Los Angeles

Experiencing homelessness during young adulthood is associated with negative health outcomes and understanding housing trajectories of young adults experiencing homelessness may aid in the development of evidence-based public health programs designed to serve this at-risk age group. In the present study, the authors examined baseline predictors of 24-month trajectories of housing stability and unsheltered housing among a sample of 271 young adults aged 18 to 25 recruited from drop-in centers in Los Angeles. In multivariate models, the authors found that identifying as multi-racial/other and better friendship quality at baseline were associated with less steep increases in the likelihood of stable housing over time. Being employed at baseline was associated with a less steep decrease in the probability of being unsheltered over time, while illicit drug use days associated with a steeper decrease in the probability of being unsheltered over time. Continued research is needed to establish important factors determining young adults' long-term housing trajectories in the effort to promote greater access and engagement with housing services.

Social Networks, Cultural Pride, and Historical Loss Among Non-Reservation American Indian / Alaska Native Emerging Adults

Health disparities among American Indian/Alaska Native (AI/AN) populations in the United States are the result of historical traumas, such as colonization, forced relocation, and federal policies focused on cultural assimilation. Culturally-tailored health interventions aim to address intergenerational trauma by emphasizing cultural strengths and building positive social connections. In this article, we explore the social network characteristics of participants of the first culturally-tailored health intervention for AI/AN emerging adults (18-25) living outside of tribal lands. Participants (N = 150; 86% female) were recruited across the United States via social media and completed online egocentric network interviews prior to the start of intervention workshops. Participants' networks were diverse in composition and structure. They were primarily composed of family and friends, were people they had regular contact with, were similar age, and provided participants with support. We tested for significant associations between network characteristics, individual characteristics (age, gender, travel to reservations, speaking tribal languages, etc.) and two dependent measures: 1) cultural pride and belongingness and 2) thoughts of historical loss. Multiple regression results show that higher proportions of network members who discussed AI/AN identity with participants and having more network members who engage in traditional practices was associated with stronger cultural pride and belongingness. Higher proportions of network members having discussion of AI/AN identity with participants was also associated with more frequent thoughts of historical loss. Controlling for network factors, no individual characteristics were associated with either dependent variable. We discuss implications for the development of culturally-tailored health interventions.

Leveraging the Full Continuum of Care to Prevent Opioid Use Disorder

Substance use disorder prevention programs are most effective when matched appropriately to the baseline risk of the population. Individuals who misuse opioids often have unique risk profiles different from those who use other substances such as alcohol or cannabis. However, most substance use prevention programs are geared toward universal audiences, neglecting key inflection points along the continuum of care. The HEAL Prevention Cooperative (HPC) is a unique cohort of research projects that represents a continuum of care, from community-level universal prevention to indicated prevention among older adolescents and young adults who are currently misusing opioids or other substances. This paper describes the theoretical basis for addressing opioid misuse and opioid use disorder across the prevention continuum, using examples from research projects in the HPC.

Parallel trajectories of vaping and smoking cannabis and their associations with mental and physical well-being among young adults

BACKGROUND

Vaping and smoking are common modes of using cannabis (THC) among young adults, but little is known about how patterns of cannabis vaping and smoking unfold over time or how using one or both types of products may differently affect mental and physical well-being. This study examines parallel processes of cannabis vaping and smoking over 5 years and mental and physical outcomes in a sample of young adults.

METHODS

Annual surveys were conducted between 2016 and 2022 with a mostly California-based cohort of 2428 young adults. Parallel process growth mixture models examined trajectories of past-month frequency of cannabis vaping and smoking from ages 20 - 25. Classes were extracted based on parallel trajectories of vaped and smoked product use. Models assessed differences in self-reported mental (anxiety, depression) and physical (ailments, subjective overall) well-being outcomes in young adulthood across classes, adjusting for demographic characteristics and mental and physical well-being at pre-baseline (average age 19).

RESULTS

Four cannabis vaping/smoking classes emerged: low use of cannabis (84.7%), decreasing smoking, low-moderate vaping (7.1%), stable moderate smoking, decreasing vaping (4.6%), and rapid increasing dual use (3.4%). Classes were similar on physical well-being indicators in young adulthood. The rapid increasing dual use class showed higher anxiety and depressive symptoms compared to other classes.

CONCLUSION

Progression to higher frequency of both vaping and smoking cannabis in young adulthood may contribute to poorer mental well-being compared to other use patterns. Targeted efforts to reduce dual vaping and smoking in young people who use cannabis may be needed.

Culturally Responsive Opioid and Other Drug Prevention for American Indian/Alaska Native People: a Comparison of Reservation- and Urban-Based Approaches

There are few substance use treatment and prevention programs for AI/AN people that integrate culturally based practices with evidence-based treatment and prevention. The National Institutes of Health's (NIH's) Helping to End Addiction Long-term (HEAL) Prevention Cooperative supports two projects focused on AI/AN populations. One focuses on youth ages 15 to 20 years living within the Cherokee Nation reservation, a multicultural rural area in northeastern Oklahoma, and the second focuses on emerging adults ages 18 to 25 years living in diverse urban areas. We provide a brief overview of the two prevention trials and a case comparison across approaches using the framework of promising practices for intervention science with Indigenous communities (Whitesell et al., 2020) related to (1) integration of Indigenous and academic perspectives to respond to community needs, (2) community partnership and engagement, (3) alignment with Indigenous cultural values and practices, (4) capacity building and empowerment, (5) implementation within complex cultural contexts, and (6) tribal oversight. Overall, these two projects highlight the importance of long-standing relationships with community partners, engaging the community at all levels to ensure that programming is culturally and developmentally appropriate, and having tribal and elder oversight. These practices are key to establishing trust and building confidence in research in these communities and ensuring that research can benefit AI/AN people. These studies showcase how strong partnerships can advance health and support the conduct of rigorous science to help pinpoint optimal health solutions by identifying efficacious, culturally grounded intervention strategies. Although the sovereign status of tribes demands this type of partnership, this research serves as a model for all community research that has a goal of improving health.

A randomized controlled trial of a brief motivational interviewing-based group intervention for emerging adults experiencing homelessness: 24-month effects on alcohol use

OBJECTIVE

Despite rates of alcohol misuse being higher among emerging adults experiencing homelessness compared to those who are stably housed, there are few brief evidence-based risk reduction programs for this population that focus on alcohol use and assess outcomes for more than 1 year. This study examines alcohol outcomes from a 24-month evaluation of AWARE, a brief motivational interviewing-based group risk reduction intervention for emerging adults experiencing homelessness.

METHOD

In a cluster randomized crossover trial, 18- to 25- year-olds received AWARE (n = 132) or standard care (n = 144) at one of three drop-in centers serving young people experiencing homelessness in Los Angeles County. We evaluated intervention effects on past month alcohol use, consequences, and related cognitions such as motivation to change behavior.

RESULTS

AWARE participants showed significant reductions over 24 months in alcohol use and negative consequences from drinking and reported significant increases in their use of drinking protective strategies. Except for drinking frequency, control group participants did not show a significant change in these outcomes.

CONCLUSIONS

Findings build on earlier work by demonstrating that AWARE is effective in reducing alcohol use and related problems among emerging adults experiencing homelessness over a 2-year period. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

A randomized controlled trial of a brief motivational interviewing-based group intervention for emerging adults experiencing homelessness: 12-Month effects on substance use and sexual risk behavior

INTRODUCTION

Few brief evidence-based risk reduction programs for emerging adults experiencing homelessness focus on the interrelated problems of substance use and sexual risk behavior. This study examines outcomes from a 12-month evaluation of AWARE, a brief Motivational Interviewing (MI)-based group risk reduction intervention for this population.

METHODS

In a cluster randomized crossover trial, N = 276 18-25-year-olds received AWARE or usual care at drop-in centers serving homeless youth in Los Angeles County. We evaluated intervention effects on substance use and condomless sex (primary outcomes), as well as drinking consequences and protective strategies, number of casual partners, self-efficacy, and motivation for change (secondary outcomes).

RESULTS

AWARE participants self-reported reductions in their alcohol use and negative consequences from drinking, and an increase in use of drinking protective strategies. AWARE participants also reported an initial decrease in drug use other than marijuana, followed by a slight uptake later on, as well as an initial increase in importance of cutting down on other drug use followed by a decrease. Control group participants did not show change in these outcomes. Among those who reported casual sex partners at both baseline and 12-month surveys, exploratory analyses indicated that AWARE participants had a 29 % decline in condomless sex with casual partners compared to a 6 % decline for control group participants.

CONCLUSIONS

Findings build on our pilot work by demonstrating that AWARE has long-term benefits on drinking among emerging adults experiencing homelessness. Further work should seek to strengthen its long-term effectiveness in reducing drug use in this population.

Risk and protective factors of social networks on alcohol, cannabis, and opioid use among urban American Indian/Alaska Native emerging adults

OBJECTIVES

Assess associations between social networks and urban American Indian/Alaska Native emerging adults' alcohol, cannabis, and opioid use and intentions.

METHOD

American Indian/Alaska Native participants ages 18-25 (N = 150; 86% female) were recruited across the United States from 12/20 to 10/21 via social media. Participants named up to 15 people whom they talked with most over the past 3 months and reported who (a) used alcohol and cannabis heavily or used other drugs (e.g., opioid use), (b) engaged in traditional practices, and (c) provided support. They also reported past 3-month alcohol, cannabis, and opioid use and intentions to use.

RESULTS

Having a higher proportion of network members engaging in regular cannabis and heavy alcohol use (but not other drugs) was associated with more frequent cannabis use and stronger cannabis use intentions. Participants with higher proportions of members engaging in heavy alcohol use, regular cannabis use, or other drug use and who did not engage in traditional practices were more likely to report cannabis use and greater intentions to use cannabis and drink alcohol. In contrast, participants with higher proportions of network members engaging in traditional practices and who did not report heavy alcohol use, regular cannabis use, or other drug use were less likely to report intentions to use cannabis or drink alcohol.

CONCLUSIONS

Findings emphasize what many studies have shown among various racial/ethnic groups-having network members who use substances increases the chance of use. Findings also highlight that traditional practices may be an important part of the prevention approach for this population. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Unpacking disparities in substance-related outcomes among racial, ethnic, sexual, and gender minoritized groups during adolescence and emerging adulthood

OBJECTIVE

Alcohol and other drug (AOD) use increases substantially from adolescence to emerging adulthood, and recent longitudinal studies show disparities in AOD-related outcomes by racial and ethnic, as well as sexual and gender minority (SGM), identities. Greater insight is needed into how individual, social, and environmental contexts interact and affect such disparities, as well as why disparate outcomes are found across different domains (e.g., social, educational, economic), even after accounting for intensity of use. This commentary addresses these important and timely issues.

METHOD

We provide a brief overview of the literature, including our own team's work over the last 14 years, to identify and understand disparities in AOD-related outcomes during adolescence and emerging adulthood across individuals with different racial and ethnic, and sexual and gender, identities. We then discuss paths forward to advance research and build a stronger evidence base, leading to the development and identification of effective interventions that can help mitigate disparities among historically marginalized adolescents and emerging adults.

RESULTS

Existing research highlights the need for further longitudinal work in several areas, including addressing contextual factors at various levels (e.g., individual, social, environmental) that may contribute to outcomes for different groups of individuals, developing and testing culturally appropriate AOD-related services, giving greater consideration to intersectionality of multiple minority identities, and using novel statistical approaches to help improve the estimation of differences across smaller subgroups of individuals in existing cohorts.

CONCLUSIONS

To inform prevention programming and policy for improving health and well-being of historically marginalized populations, it is important to continue our efforts to understand disparities in AOD-related outcomes using multidisciplinary, equity, and intersectionality lenses.

Secondary Outcomes of a Brief Group Alcohol and Risky Sex Intervention for Emerging Adults Experiencing Homelessness

AWARE is a four-session group-based motivational enhancement intervention designed to reduce substance use and sexual risk behavior among emerging adults experiencing homelessness. Expanding on promising intervention effects on substance use and risky sex outcomes, this study explored intervention effects on changes in secondary outcomes from baseline to 12-month post-intervention: depression, physical health (general health ratings, physical symptoms), social functioning (satisfaction, quality of friendships), and housing stability. Among the 240 participants with baseline and 12-month follow-up data, we found small effect sizes generally favoring the intervention over usual care for all outcomes. Findings show promise that addressing substance use and risky sexual behavior through interventions in drop-in centers could benefit emerging adults experiencing homelessness in additional areas of their lives. More work is needed to understand how interventions could be tailored to more directly address these outcomes and sustain changes in the long-term.

Childhood adversity and developmental trajectories of alcohol and cannabis co-use

OBJECTIVE

A large body of literature has noted detrimental effects of childhood adversity on young adult behavioral health, yet few studies have assessed how early childhood adversity influences the development of alcohol and cannabis co-use.

METHOD

In the present study we use data from an ongoing longitudinal cohort (N = 2507) to understand how early childhood adversity influences transitions into alcohol and cannabis co-use trajectories. We also explore how sex, depression, and anxiety are associated with transition probabilities. We used latent transition analysis to examine transitions from emergent childhood adversity classes to classes of parallel alcohol and cannabis co-use from ages 17 to 24 years.

RESULTS

Those who reported high levels of childhood adversity were more likely to transition into classes with relatively chronic and rapidly increasing alcohol and cannabis co-use during young adulthood. Young adults who both experienced high levels of childhood adversity and transitioned into increasing alcohol and cannabis co- use trajectories were more likely to be male and meet clinical cutoff for depression.

CONCLUSION

Our results indicate an incrementally more nuanced set of risk profiles, with differential risk of alcohol and cannabis co-use trajectories, dependent on one's experience of childhood adversity.

PUBLIC HEALTH SIGNIFICANCE

Results of the present study note important heterogeneity in alcohol and cannabis co-use throughout young adulthood, with general trends showing increases in co-use. The present study also shows differential risk of alcohol and cannabis co-use dependent on prior experience of childhood adversity.

Trajectories of Emerging Adults' Binge Drinking and Depressive Symptoms and Associations With Sexual Violence Victimization: Examining Differences by Sexual and Gender Minority Status

We examined longitudinal associations between binge drinking (BD), depressive symptoms, and sexual violence (sexual harassment and sexual assault) among sexual and gender minority (SGM) and non-SGM emerging adults. Data were drawn from four annual web-based surveys of a diverse cohort of 2,553 emerging adults, spanning from approximately age 19 (2016) to age 22 (2020). About 18% were SGM individuals. We tested a multigroup parallel process latent growth curve model (recent depression symptoms; past-year BD) with time-varying covariates (past-year sexual harassment; sexual assault) to determine associations of sexual violence with BD and depression outcomes over time, and whether growth curves and associations differed by SGM status. For both SGM and non-SGM emerging adults, past-year sexual harassment was associated with depressive symptoms at each time point, but harassment was not associated with BD. For both groups, sexual assault was associated with both depressive symptoms and BD. To our knowledge, this is the first study to examine longitudinal, contemporaneous associations of sexual violence (including both harassment and assault as distinct constructs), with BD and depressive symptoms among racially and ethnically diverse emerging adults, comparing SGM and non-SGM groups. Although our models do not disentangle directionality or causality, the findings suggest the need to address sexual violence victimization (assault and harassment) in the context of depression screening and treatment, and vice versa. We discuss a number of intervention strategies currently in use for an implicitly non-SGM general population that could be adapted for greater inclusion of and relevance to SGM populations.

Risk and Resilience Among Families in Urban AI/AN Communities: the Role of Young Adults

Urban American Indian/Alaska Native (AI/AN) young adults and their families are often geographically or socially distant from tribal networks and traditional social support. Young adults can be especially vulnerable to cultural and social disconnection, so understanding how AI/AN family functioning can augment resilience and protect against risk is important. This research precedes a preventive substance use intervention study and explores urban Native family functioning, emphasizing the role of young adults by analyzing data from 13 focus groups with urban AI/AN young adults (n = 32), parents (n = 25), and health providers (n = 33). We found that young adults can and want to become agents of family resilience, playing active roles in minimizing risks and strengthening family functioning in both practical and traditional ways. Also, extended family and community networks played a vital role in shaping family dynamics to support resilience. These resilience pathways suggest potential targets for intervention.

Study design to evaluate a web-intervention to prevent alcohol and cannabis-impaired driving and use among adolescents in driver education

BACKGROUND

Alcohol and cannabis are the most commonly used substances among adolescents in the U.S. The consequences related to using both substances together are significantly higher relative to use of either substance alone. Teens' propensity to engage in risky driving behaviors (e.g., speeding, rapid lane changes, and texting) and their relative inexperience with the timing and duration of cannabis' effects puts them at heightened risk for experiencing harms related to driving under the influence. Use of alcohol and cannabis peak at age 16, the legal age teens may apply for a provisional driver's license in some states. Targeting novice teen drivers prior to licensure is thus an ideal time for prevention efforts focused on reducing alcohol and/or cannabis initiation, use, and impaired driving.

METHODS

The current study proposes to evaluate the efficacy of webCHAT among 15.5 to 17-year-old adolescents (n = 150) recruited at driver education programs. WebCHAT is a single session online intervention that aims to prevent alcohol and cannabis use and risky driving behaviors. We will recruit adolescents enrolled in driver education programs, and stratify based on whether they used cannabis and/or alcohol in the past 3 months (60% screening negative and 40% screening positive). All participants will receive usual driver education and half will also receive webCHAT. We will test whether webCHAT in addition to usual driver education reduces alcohol and/or cannabis initiation or use and reduces risky driving attitudes and behaviors (intent to drive after drinking/using, riding as a passenger with someone who drank/used) compared to teens in usual driver education over a 6-month period. We will also explore whether variables such as beliefs and perceived norms serve as explanatory mechanisms for our outcomes.

DISCUSSION

The study has the potential to promote public welfare by decreasing adolescent initiation and use of cannabis and alcohol and reducing risky driving behaviors that can have substantial monetary, personal, and social costs. The study recruits adolescents who are at risk for substance use as well as those who are not and it is delivered remotely during a teachable moment when adolescents receive driver education.

A randomized controlled trial of an online alcohol and sexual risk prevention program for college students studying abroad

INTRODUCTION

American college students who study abroad experience increases in their drinking behavior, concerning risky sexual behaviors, and high rates of sexual violence while abroad. Despite these concerns, institutions offer limited programming to students prior to departure to address these risks and no empirically supported interventions currently exist that are targeted toward preventing increased drinking, risky sexual behavior, and sexual violence abroad. To help address alcohol and sexual risk abroad, we designed a brief, single-session online predeparture intervention focused on risk and protective factors known to associate with alcohol and sexual risk abroad.

METHODS

Using a sample of 650 college students from 40 home institutions, we conducted a randomized controlled trial of the intervention and tested its effects on drinking (drinks per week, binge drinking frequency, alcohol related-consequences), risky sexual behaviors, and sexual violence victimization during the trip abroad (first month, last month abroad) and one-month and three-months after return home.

RESULTS

We observed small, but nonsignificant, intervention effects on drinks per week and binge drinking days during the first month abroad and three months after they had returned home to the United States, and small, significant effects on risky sexual behaviors during the first month abroad. The study found no observable effects at any time point for alcohol-related consequences or for sexual violence victimization abroad.

CONCLUSIONS

Though mostly nonsignificant, small initial intervention effects were promising in this first empirical test of an alcohol and sexual risk prevention program for study abroad students. However, students may need more intensive programming with booster sessions to experience lasting intervention effects during this particularly high-risk period.

Food insecurity, sleep, and cardiometabolic risks in urban American Indian/Alaska Native youth

OBJECTIVES

Food insecurity contributes to racial/ethnic disparities in health. This is the first study to examine associations among food insecurity, sleep, and cardiometabolic outcomes in urban American Indian/Alaska Native (AI/AN) youth.

DESIGN

Participants were 142 urban AI/AN youth (mean age = 14 years, 58% female). Food insecurity and self-reported sleep disturbance were measured using validated surveys. A multi-dimensional sleep health composite was derived using questionnaires (ie, satisfaction, alertness) and actigraphy-derived indices (ie, duration, efficiency, regularity, timing). Cardiometabolic measures included body mass index, blood pressure, glycosylated hemoglobin, waist circumference, cholesterol, and triglycerides. Covariates were sex, age, and single-parent household.

RESULTS

Greater food insecurity was significantly associated with greater body mass index (b = 0.12, p = .015), higher systolic blood pressure (b = 0.93, p = .03), and greater sleep disturbance (b = 1.49, p < .001), and marginally associated with lower sleep health composite scores (b = -0.09, p = .08). There was a significant indirect path from greater food insecurity to greater waist circumference through poorer sleep health (0.11, 95% bootstrapping CI: [0.01, 0.30]).

CONCLUSION

Food insecurity is an important correlate of sleep and cardiometabolic health among urban AI/AN youth and should be addressed to reduce emerging health risks during this important developmental period. Policies to reduce food insecurity and increase access to healthy foods as well as sleep interventions for these youth could help, as preliminary findings suggest that sleep health may mediate the negative impact of food insecurity on cardiometabolic risks.

Directional associations between cannabis use and depression from late adolescence to young adulthood: the role of adverse childhood experiences

BACKGROUND AND AIMS

Although the co-occurrence of cannabis and depression is well established, less is known about the temporal sequence of cannabis use and depression. The present study had three main aims: to test a symptom-driven pathway in which depression may drive increases in cannabis use, to test a substance-induced pathway in which cannabis use may drive increases in depression and to assess a shared vulnerability model assessing associations between individuals who have (and have not) experienced adverse childhood experiences (ACEs).

DESIGN

Data are from an ongoing, longitudinal, cohort study (n = 2234). Data were set up in an accelerated longitudinal design from age 17 to 24 years.

SETTING

Initial sample was recruited from Southern California, USA. The majority of participants still live in Southern California.

PARTICIPANTS

On average, participants were aged 18 years at wave 8, with more than half identifying as female (54.3%; n = 1350). Most participants identified as Hispanic (1127; 45.4%), followed by non-Hispanic white (510; 20.5%), Asian (503; 20.2%), multi-racial/other (284; 11.4%) and non-Hispanic black (60; 2.2%).

MEASUREMENTS

Primary outcomes were past-month days of cannabis use and depression symptoms [patient health questionnaire (PHQ)-8]. The Adverse Childhood Experiences scale was used as our main grouping measure.

FINDINGS

In the full sample, we showed that prior levels of depression symptoms were associated with a decrease in cannabis use [opposite to the proposed symptom driven model; B = -0.33 (-0.58, -0.09)]. Dynamic coupling parameters noted individuals who evidenced greater increases in cannabis use between two prior ages reported greater increases in depressive symptoms between subsequent ages [support for a substance-induced pathway; B = 0.53 (0.18, 0.89)]. Similar to the overall sample, for those who had not experienced ACEs, as cannabis use increased we saw a steady increase in depression [support for a substance induced pathway; B = 0.14 (0.04, 0.29)]. However, for those who experienced ACEs, as cannabis use increased we saw a consistent decrease in depression [opposite to the proposed substance-induced pathway; B = -0.18 (-0.28, -0.08)].

CONCLUSION

There is mixed support for both symptom-driven and substance-induced pathways between cannabis use and depression.

Directional associations between cannabis use and anxiety symptoms from late adolescence through young adulthood

BACKGROUND

Two major theories aid in explaining the association between anxiety and cannabis use: a symptom-driven pathway (heightened anxiety precedes greater cannabis use) and a substance-induced pathway (greater use precedes heightened anxiety). Although the co-occurrence of cannabis use and anxiety symptomology is well-established, less is known about the temporal sequence of cannabis use and anxiety symptomology over the course of young adult development METHODS: Data are from an ongoing, longitudinal, cohort study. All prospective analyses used data from wave 8, when participants were between the ages of 17 and 20, through wave 13, when participants are between ages 21 and 24 (N = 2995). Data were set up in accelerated longitudinal design in which we estimated a series of latent difference score models between anxiety and cannabis use from 17 to 24 years old. Models were estimated for men and women, separately.

RESULTS

For the overall sample and men, greater cannabis use predicted greater subsequent increases in anxiety; however, greater anxiety symptoms were associated with decreasing cannabis use. For women, results were more complex. A positive association was noted between prior, trait-like levels of anxiety predicting greater change (increasing) in anxiety symptomology. However, when change is predicted by prior change we see that cannabis use decreases among women who have recently experienced an increase in anxiety CONCLUSION: The nuanced set of results from this study support a dynamic interplay between anxiety symptoms and cannabis use, with important sex differences observed. Overall, our results pave the way for rethinking our guiding theories to include a more robust, flexible, and dynamic model for understanding associations between substance use and mental health symptomology during a key period of development.

A latent class approach to understanding longitudinal sleep health and the association with alcohol and cannabis use during late adolescence and emerging adulthood

OBJECTIVE

Sleep is a multi-dimensional health behavior associated with elevated risk of substance use. This is the first study to utilize a latent class approach to characterize sleep health across multiple dimensions and across time from late adolescence to emerging adulthood, and to examine associations with alcohol and cannabis use trajectories.

METHODS

The sample included 2995 emerging adults (mean ages = 18 to 24 years across six waves of data collection; 54% female) who provided data on sleep dimensions (quality, duration, and social jetlag) and frequency and consequences of alcohol and cannabis use. Longitudinal latent class analysis (LLCA) models characterized participants according to the three sleep dimensions. Latent growth models examined trajectories of frequency and consequences of alcohol or cannabis use over time among emergent sleep classes, with and without controlling for covariates.

RESULTS

LLCA models identified four sleep classes: good sleepers (n = 451; 15.2%); untroubled poor sleepers (n = 1024; 34.2%); troubled, moderately good sleepers (n = 1056; 35.3%); and suboptimal sleepers (n = 460; 15.4%). Good sleepers reported significantly lower levels of alcohol or cannabis use and consequences, and less of an increase in alcohol consequences as compared to suboptimal sleepers.

CONCLUSIONS

Persistent poor sleep health was associated with higher levels of alcohol and cannabis use and consequences, and greater increases in alcohol-related consequences during the transition from late adolescence to emerging adulthood. Findings have important clinical implications, highlighting that addressing multi-dimensional sleep health may be an important, novel target of intervention to reduce substance use frequency and consequences.

Feasibility and acceptability of incorporating social network visualizations into a culturally centered motivational network intervention to prevent substance use among urban Native American emerging adults: a qualitative study

Background

Coupling social network visualizations with Motivational Interviewing in substance use interventions has been shown to be acceptable and feasible in several pilot tests, and has been associated with changes in participants’ substance use and social networks. The objective of this study was to assess acceptability and feasibility of an adaptation of this behavior change approach into a culturally centered behavior change intervention for American Indian/Alaska Native (AI/AN) emerging adults living in urban areas. AI/AN populations experience high rates of health disparities and substance use. Although 70% of AI/AN people live outside of tribal lands, there are few culturally tailored health interventions for these AI/AN populations. Social networks can both increase and discourage substance use. Leveraging healthy social networks and increasing protective factors among urban AI/AN emerging adults may help increase resilience.

Methods

We conducted thirteen focus groups with 91 male and female participants (32 urban AI/AN emerging adults ages 18–25, 26 parents, and 33 providers) and one pilot test of the three workshop sessions with 15 AI/AN emerging adults. Focus group participants provided feedback on a proposed workshop-based intervention curriculum that combined group Motivational Interviewing (MI) and social network visualizations. Pilot workshop participants viewed their own social networks during group MI sessions focused on substance use and traditional practices and discussed their reactions to viewing and discussing their networks during these sessions. We used a combination of open coding of focus group and workshop session transcripts to identify themes across the group sessions and content analysis of comments entered into an online social network interview platform to assess the extent that participants had an intuitive understanding of the information conveyed through network diagrams.

Results

Focus group and pilot test participants reacted positively to the intervention content and approach and provided constructive feedback on components that should be changed. Themes that emerged included feasibility, acceptability, relevance, understandability, and usefulness of viewing personal network visualizations and discussing social networks during group MI workshops. Workshop participants demonstrated an intuitive understanding of network concepts (network composition and structure) when viewing their diagrams for the first time.

Conclusions

Social network visualizations are a promising tool for increasing awareness of social challenges and sources of resilience for urban AI/AN emerging adults. Coupled with Motivational Interviewing in a group context, social network visualizations may enhance discussions of network influences on substance use and engagement in traditional practices.

Traditions and Connections for Urban Native Americans (TACUNA): Utilizing community-based input to develop an opioid prevention intervention for urban American Indian/Alaska Native emerging adults

INTRODUCTION

Although approximately 70% of American Indian/Alaska Native (AI/AN) people reside in urban areas, very few opioid prevention interventions exist for urban AI/AN emerging adults. The study team conducted this study to develop Traditions and Connections for Urban Native Americans (TACUNA), a new opioid prevention intervention for urban AI/AN emerging adults ages 18-25. TACUNA comprises three 2-hour virtual workshops.

METHODS

We conducted thirteen focus groups in three urban communities in northern, central, and southern California (six with urban AI/AN emerging adults ages 18-25 [n = 32], four with parents [n = 26], and three with providers [n = 33]) to identify relevant intervention domains. We then incorporated the results of a rapid analysis of the focus groups to develop intervention workshops followed by a pilot test (n = 15) to further refine the intervention and assess feasibility.

RESULTS

Four major domains emerged from focus groups: 1) historical trauma/cultural identity, 2) AI/AN traditional practices, 3) social networks, and 4) substance use. We incorporated all feedback relating to each theme to enhance content of the TACUNA intervention. Pilot test participants felt that TACUNA content was interesting, addressed their issues and concerns as urban AI/AN emerging adults, and believed that the program could help them to establish cultural and social connections to live healthier lives.

CONCLUSIONS

Research activities demonstrate how a community-informed and culturally grounded opioid prevention intervention can be developed for urban AI/AN emerging adults. Addressing issues and challenges with culturally and developmentally relevant intervention content can help to build resilience and hopefully decrease opioid use among this underserved population.

Neighborhood social environment change in late adolescence predicts substance use in emerging adulthood

This study examines associations of changes in perceived and objective (census-based) neighborhood social environment variables during adolescence with alcohol and marijuana outcomes in emerging adulthood using two waves of data (2013-14 and 2019-20) from a cohort in Southern California (n = 1249). Increasing perceived disorganization predicted greater alcohol consequences and socialization with peers using marijuana. Decreasing objective neighborhood SES predicted fewer alcohol consequences and greater socialization with peers drinking alcohol. Unexpectedly, both decreasing and increasing perceived social cohesion predicted fewer alcohol consequences. Increasing perceived social cohesion predicted lower solitary alcohol use. Findings identify potential environmental targets to prevent substance use during the transition to emerging adulthood, but more research is warranted to understand the complex findings for alcohol consequences.

Cross-Lagged Associations of Insecure Attachment Style, Alcohol Use, and Sexual Behavior During Emerging Adulthood

Insecure romantic attachment style has been associated with greater substance use and higher risk sexual behavior, but the temporal nature of these associations is not well-understood. This study examined whether having a more insecure attachment style was associated with greater engagement in higher-risk sexual behavior over time and, if so, whether this was mediated by more frequent alcohol use. We used three annual waves of survey data from a diverse California cohort (N = 2371) who were assessed from ages 19 to 21-22 years. Separate cross-lagged models examined temporal associations of insecure romantic attachment style (anxious and avoidant), past month alcohol use frequency, and sexual behavior (number of sex partners, condomless sex with casual and steady partners). Attachment anxiety was not directly associated with sexual behavior. Rather, a consistent pattern across waves showed that greater attachment anxiety was associated with more frequent alcohol use at the next wave, which, in turn, was associated with having more sex partners and condomless sex with casual and steady partners one year later. In contrast, greater attachment avoidance was directly associated with having fewer sex partners, and its associations with condomless sex differed across partner type and assessment waves. Attachment avoidance was unrelated to alcohol use frequency. Results indicated that both anxious and avoidant attachment styles were associated with higher-risk sexual behavior, but in different ways and through different mechanisms. Future research may want to examine whether the effectiveness of sexual risk reduction programs for young people is enhanced by discussing attachment style and tailoring the curriculum accordingly.

COVID-19 Vaccination Rates and Attitudes Among Young Adults With Recent Experiences of Homelessness

PURPOSE

This study provides information on COVID-19 vaccination and attitudes among young adults with recent experiences of homelessness.

METHODS

Participants (n = 134) from a clinical trial of a risk reduction program for youth experiencing homelessness in Los Angeles completed survey items about COVID-19 vaccinations between March and October 2021.

RESULTS

A total of 29% of respondents were vaccinated, and 50% were not interested in getting vaccinated. Among the unvaccinated, 58% had not been offered the vaccine; furthermore, 38%-45% had strong distrust of the vaccine and were worried about its harmfulness. Vaccination status was generally unrelated to demographics, housing instability, service use, substance use, or mental health.

DISCUSSION

Our data suggest that vaccination rates are lower among young adults with recent experiences of homelessness than those in the general US population. The results suggest a need for greater direct outreach that includes both offering the vaccine and addressing misconceptions about its safety to increase vaccination rates in this population.

Patterns and correlates of cannabidiol product and marijuana co-use in a sample of U.S. young adults

OBJECTIVE

Cannabis-derived products containing cannabidiol with no or minimal levels of delta 9-tetrahydrocannabinol (CBD products) are widely available in the United States and use of these products is common among young adults and those who use marijuana. The purpose of this study was to examine patterns and correlates of CBD product use and co-use with marijuana in a sample of young adults.

METHOD

The study used cross-sectional survey data collected in 2019-2020 from a cohort of young adults (n = 2534; mean age 23) based primarily in California. The survey assessed lifetime, past-year, and past-month frequency and type of CBD products used, frequency and amount of marijuana consumption and indicators of marijuana use-related problems. Linear, Poisson, and logistic regression models compared individuals reporting past month CBD-only use, marijuana-only use, concurrent CBD + marijuana use (co-use), and use of neither product. Among those reporting co-use, we examined associations between CBD use frequency and marijuana use frequency and heaviness of use (occasions per day) and indicators of problem marijuana use (e.g., Cannabis Use Disorder Identification Test Short-Form, solitary use, marijuana consequences).

RESULTS

Approximately 13% of respondents endorsed past-month CBD use; of these, over three-quarters (79%) indicated past-month co-use of marijuana. Among individuals reporting co-use, more frequent CBD use was associated with more frequent and heavier marijuana use but was not associated with marijuana use-related problems.

CONCLUSIONS

CBD use was common and associated with higher levels of marijuana consumption in this sample. Routinely assessing CBD use may provide a more comprehensive understanding of individuals' cannabis product consumption.

Alcohol use and cannabis use trajectories and sexual/gender minority disparities in young adulthood

OBJECTIVE

Sexual and gender minority (SGM) young people may use alcohol or cannabis (A/C) at higher rates that non-SGM peers, but little is known about whether SGM young adults experience poorer health, psychosocial, and other outcomes at similar levels of A/C use.

METHOD

We used longitudinal survey data from a community cohort recruited from California middle schools in 2008 (average age 11.5) and followed across 12 waves through 2020. Participants reported on past-month A/C use at each wave. Individuals also reported SGM status as well as outcomes in multiple domains in Wave 12. Sequelae of change models tested differences in intercept and slope for A/C use trajectories from Waves 1-12 across SGM groups, and simultaneously examined differences in outcomes by SGM status adjusting separately for A/C trajectories.

RESULTS

SGM (n = 445) and non-SGM (n = 2,089) groups did not differ on baseline probability of A/C use. SGM individuals showed steeper increases in probability of cannabis but not alcohol use over time. Adjusting for trajectories of A/C use, SGM individuals had significant disparities relative to non-SGM peers with respect to: Employment and economic stability, criminal justice involvement, social functioning, subjective physical health, behavioral health, and perceived unmet mental health treatment need.

CONCLUSIONS

At the same levels of A/C use from middle school through young adulthood, SGM individuals show disparities in multiple domains compared to non-SGM peers. Targeted efforts to reduce substance use in conjunction with other structural disadvantages experienced by SGM youths are needed to address the emergence of disparities in young adulthood.

Loneliness and multiple health domains: associations among emerging adults

Emerging adults (18–25 years), particularly racially/ethnically diverse and sexual and gender minority populations, may experience loneliness following major life transitions. How loneliness relates to health and health disparities during this developmental period is not well understood. We examine associations of loneliness with physical (self-rated health), behavioral (alcohol/marijuana consequences; nicotine dependence), and health behavior outcomes (weekday and weekend sleep; trouble sleeping), and investigate moderating effects by sex, race/ethnicity, and sexual/gender minority (SGM) status. Adjusted models using cross-sectional data from 2,534 emerging adults, predominantly in California, examined associations between loneliness and each outcome and tested interactions of loneliness with sex, race/ethnicity, and SGM status. Higher loneliness was significantly associated with worse self-rated health, higher marijuana consequences, less weekday sleep, and greater odds of feeling bothered by trouble sleeping. None of the interactions were significant. Findings suggest that interventions to reduce loneliness may help promote healthy development among emerging adults across subgroups.

Mental health, family functioning, and sleep in cultural context among American Indian/Alaska Native urban youth: A mixed methods analysis

Mental health problems contribute significantly to the global burden of disease. Driven in part by family stressors and insufficient sleep, mental health disproportionately affects low SES urban adolescents. In the United States, American Indian/Alaska Native (AI/AN) youth exhibit excessively high rates of mental health problems. Family functioning is strongly associated with adolescent mental health, and sleep problems may serve as a pathway between family functioning and mental health. Using mixed methods we examine the associations among family functioning, subjective- and actigraphy-measured sleep, mental health (depressive and anxiety symptoms), and cultural identity in a sample of urban AI/AN youth. All participants (N = 142) completed surveys; a random subsample (n = 26) completed qualitative interviews to assess family and cultural dynamics related to sleep, which informed hypothesized direct and indirect effects that were tested using survey data. Narratives identified mechanisms of family cohesion (e.g., daily interactions that build perceived family togetherness and family-centered traditional activities) and the role that family cohesion plays in sleep (e.g., ensuring stability of sleep environments). Path analysis showed direct effects of improved family functioning on fewer depressive and anxiety symptoms, and indirect effects through lower self-reported sleep disturbance (but not through greater actigraphy-measured sleep duration or efficiency). Cultural identity did not moderate effects in quantitative tests. Our findings illustrate the complex associations among family functioning, sleep, and mental health in AI/AN youth. Family-based interventions to improve adolescent mental health should address modifiable intervention targets such as sleep, and address sources of both risk and resilience relevant to urban AI/AN families, including extended family and cultural practices.

Longitudinal effects of adverse childhood experiences on substance use transition patterns during young adulthood

BACKGROUND

Few studies have investigated how adverse childhood experiences are associated with substance use patterns during young adulthood, a crucial developmental period.

OBJECTIVE

The objective of this study was to extend current knowledge on the association between adverse childhood experiences and patterns of substance use among young adults. We also sought to understand how current mental health status and biological sex influences these patterns.

PARTICIPANTS AND SETTING

The current study utilized wave 8-wave 11 data of a longitudinal cohort study (N = 2880).

METHODS

We used latent transition analysis (LTA) to understand stability and transition patterns of substance use across participants who reported adverse childhood experiences (ACEs+) versus those who did not (ACEs-). Latent class regression was used to assess contemporaneous effects of mental health and sex on classes over time.

RESULTS

Both groups had similar patterns of substance use emerge at each timepoint: High all; Binge, tobacco, cannabis; and Steady/increasing binge drinking. ACEs+ had a higher proportion of youth in the High all class and much higher stability in this class, compared to the ACEs- group. Those in the ACES+ group were less likely to transition out of a riskier class. Mental health and sex showed differential effects across ACEs groups.

CONCLUSION

Results point to increased risk of polysubstance use, including opioids and prescription medications, among those who reported adverse childhood events. Future work may explore protective, malleable, factors that may confer reduced risk of long-term polysubstance use.

Integrating traditional practices and social network visualization to prevent substance use: study protocol for a randomized controlled trial among urban Native American emerging adults

BACKGROUND

Nonmedical use of prescription opioids (defined as taking opioid medications for hedonic effects or in a manner other than prescribed) and the use of heroin have emerged in recent years as major public health concerns in the United States. Of particular concern is the prevalence of opioid use among emerging adults (ages 18-25), as this is a developmental period of heightened vulnerability and critical social, neurological, and psychological development. Data from 2015 show that American Indian/Alaska Native (AI/AN) people have the highest rates of diagnosis for opioid use disorders (OUDs). One recent study found that the overdose death rate among urban-dwelling AI/AN individuals was 1.4 times higher compared to those living in rural areas. To date, there are no evidence-based prevention programs addressing opioid use among urban AI/AN emerging adults that integrate culturally-appropriate strategies with evidence-based treatment. Traditions and Connections for Urban Native Americans (TACUNA) builds on our prior work with AI/AN communities across California to develop and evaluate culturally appropriate programming to address opioid, alcohol, and cannabis use among urban AI/AN emerging adults.

METHODS/DESIGN

In a randomized controlled trial, 18-25 year old urban AI/AN emerging adults will receive either TACUNA (n = 185), which comprises three virtual workshops utilizing motivational interviewing, social network visualization, and integrating traditional practices and a wellness circle, or one virtual culturally sensitive opioid education workshop (n = 185). We will evaluate intervention effects on primary outcomes of frequency of opioid, alcohol, and cannabis use, as well as secondary outcomes of social network characteristics and cultural connectedness, over a 12-month period.

DISCUSSION

This project has the potential to expand the range and effectiveness of opioid, alcohol, and cannabis services for urban AI/AN emerging adults by addressing the opioid epidemic and use of other substances at both the community and individual level. In addition, it provides important culturally grounded conceptual and practical information to advance the field of substance use interventions and enhance resiliency among this population.

Unveiling an 'invisible population': health, substance use, sexual behavior, culture, and discrimination among urban American Indian/Alaska Native adolescents in California

Objectives: There are limited public health data on urban American Indian/Alaska Native (AI/AN) populations, particularly adolescents. The current study attempted to address gaps by providing descriptive information on experiences of urban AI/AN adolescents across northern, central, and southern California.Design: We describe demographics and several behavioral health and cultural domains, including: alcohol and other drug (AOD) use, risky sexual behavior, mental and physical health, discrimination experiences, involvement in traditional practices, and cultural pride and belonging. We recruited 185 urban AI/AN adolescents across northern, central, and southern California from 2014 to 2017 who completed a baseline survey as part of a randomized controlled intervention trial.Results: Average age was 15.6 years; 51% female; 59% of adolescents that indicated AI/AN descent also endorsed another race or ethnicity. Rates of AOD use in this urban AI/AN sample were similar to rates for Monitoring the Future. About one-third of adolescents reported ever having sexual intercourse, with 15% reporting using alcohol or drugs before sex. Most reported good mental and physical health. Most urban AI/AN adolescents participated in traditional practices, such as attending Pow Wows and learning their tribal history. Adolescents also reported discrimination experiences, including being a victim of racial slurs and discrimination by law enforcement.Conclusions: This study describes a select sample of California urban AI/AN adolescents across several behavioral health and cultural domains. Although these adolescents reported numerous discrimination experiences and other stressors, findings suggest that this sample of urban AI/AN teens may be particularly resilient with regard to behavioral health.

Poly-victimization and opioid use during late adolescence and young adulthood: Health behavior disparities and protective factors

OBJECTIVE

Recent work has attempted to uncover heterogeneity in experiences of victimization. However, few studies have included important trauma-related characteristics such as known perpetrator, fear of life or injury, and negative reactions to disclosure. Little focus on potentially important subgroup differences including sexual/gender identity, race/ethnicity, and socioeconomic status as well as protective factors have been assessed.

METHOD

Participants (N = 2,880) completed four annual surveys during late adolescence and the transition to young adulthood as part of an ongoing longitudinal study. Latent class analysis was used to extract classes of victimization and trauma-related characteristics. Latent class regression was used to understand how demographic covariates were related to class membership. Finally, discrete-time survival mixture analysis was used to assess latency to opioid use from ages 17 to 24 years, and how demographic and protective factors influenced opioid use across emergent classes.

RESULTS

The four-class solution fit the data best: sexual abuse and indirect violence + high trauma characteristics (n = 79, 3.6%); high all + high trauma characteristics (n = 177; 8.1%); chronic emotional abuse + trusted perpetrator (n = 263; 12.1%); and low all (n = 1,656; 76.1%). Latent class regression results indicated differential risk of class membership by sexual/gender minority status, sex assigned at birth, race/ethnicity, and socioeconomic status. Survival analysis noted shorter latency to opioid use across all classes compared to the low all class. Self-efficacy and neighborhood cohesion emerged as important protective factors.

CONCLUSION

Furthermore, results highlight key individual- and community-level protective factors that decrease the risk of opioid use. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

Density of medical and recreational cannabis outlets: racial/ethnic differences in the associations with young adult intentions to use cannabis, e-cigarettes, and cannabis mixed with tobacco/nicotine

BACKGROUND

Differences in access to medical versus recreational cannabis outlets and their associations with intentions to use cannabis have not yet been examined among young adults. This study compares the associations between densities of medical versus recreational cannabis outlets and young adults' intentions to use cannabis, electronic cigarettes, and cannabis mixed with tobacco/nicotine products. Racial/ethnic differences in these associations were examined.

METHODS

Young adults ages 18-23 (mean age = 20.9) in Los Angeles County were surveyed online in 2018 after the legalization of recreational cannabis (n = 604). Multiple linear regressions were estimated for the entire sample and stratified by race/ethnicity. Outcomes were intentions to use cannabis, electronic cigarettes, and cannabis mixed with tobacco/nicotine in the next 6 months. Density was measured as the number of medical cannabis dispensaries (MCDs), recreational cannabis retailers (RCRs), and outlets of any type within 5 miles of respondents' homes.

RESULTS

Living near more outlets of any type was not significantly associated with intentions to use in the full sample, adjusting for individual- and neighborhood-level characteristics. However, race/ethnicity-stratified models indicated that living near more outlets of any type and more RCRs were significantly associated with stronger co-use intentions among white young adults. Higher MCD density was marginally associated with stronger co-use intentions among Asian young adults. However, higher MCD density was significantly associated with lower intentions to use e-cigarettes among Hispanic young adults.

CONCLUSIONS

The results suggest racial/ethnic differences in the impact of living near cannabis outlets on intentions to use. Prevention efforts targeting young adults who live near more cannabis outlets may be especially beneficial for white and Asian young adults.

Drum-Assisted Recovery Therapy for Native Americans (DARTNA): Results from a feasibility randomized controlled trial

Alcohol and other drug (AOD) use among American Indians and Alaska Natives (AI/ANs) is a significant health issue in the United States. However, few evidence-based substance use interventions that utilize AI/AN traditional practices, such as drumming, exist. The current study is a feasibility randomized controlled trial (RCT) analyzing the potential benefits of DARTNA (Drum-Assisted Recovery Therapy for Native Americans) among 63 AI/AN adults seeking substance use treatment within an urban area in southern California. We compared DARTNA participants to usual care plus, which involved an integrated multimedia health educational program and usual care from providers for AOD use. At end of treatment, DARTNA participants reported significantly lower cognitive impairment and lower counts of physical ailments. Given that this was a feasibility trial, we also used Cohen's d = 0.20 or odds ratio = 2 or 0.5 to determine clinical significance. At end of treatment, we found promising benefits for DARTNA participants related to better physical health, fewer drinks per day, and lower odds of marijuana use in the past 30 days compared to the control group. Using these criteria, at 3-month follow-up, DARTNA participants reported less adoption of 12-step principles, less cognitive impairment, and lower anxiety with relationships. However, DARTNA participants reported more drinks per day and more cigarettes compared to the control group. Overall, this study demonstrates feasibility of conducting an RCT with AI/AN people in urban settings and highlights how a substance use treatment intervention utilizing drumming may help to meet the diverse needs of AI/AN people seeking substance use treatment.

Mental Health, Physical Health, and Cultural Characteristics Among American Indians/Alaska Natives Seeking Substance Use Treatment in an Urban Setting: A Descriptive Study

Although approximately 70% of American Indians/Alaska Natives (AI/ANs) reside in urban areas, our knowledge of risk and protective factors among AI/ANs seeking substance use treatment within urban areas is limited. We analyze substance and commercialized cigarette use, AI/AN cultural identity and involvement, physical health and cognitive functioning, and mental health symptoms among 63 AI/AN adults seeking substance use treatment within an urban area in California. Alcohol (37%), marijuana (27%), and methamphetamine (22%) were the most commonly reported substances. Sixty-two percent used commercialized tobacco use. The majority of AI/AN adults (78%) engaged in at least one traditional practice during the past month and endorsed high levels of spiritual connectedness. Those who engaged in traditional practices demonstrated significantly less depression (p = 0.007) and anxiety (p = 0.04). Medical and mental health issues were not prominent, although participants revealed high levels of cognitive impairment. Results highlight the importance of utilizing AI/AN traditional practices for AI/AN adults seeking substance use treatment within urban areas. Clinical Trials Registry Number NCT01356667.

Early and Late Adolescent Factors that Predict Co-use of Cannabis with Alcohol and Tobacco in Young Adulthood

The changing legal landscape of cannabis in the USA has coincided with changes in how cannabis is used, including its co-use with other substances. This study analyzed 10 years of data from a diverse cohort of youth (N = 2429; 54% Hispanic, 16% Asian, 16% white, 3% black, 10% multiracial) to examine predictors in early and late adolescence of co-use of alcohol with cannabis (AC) and tobacco with cannabis (TC) at age 21. Two forms of co-use were examined: concurrent (use of both substances in past month) and sequential (use of one substance right after the other). Analyses focused on four predictor domains: individual (e.g., resistance self-efficacy), peer (e.g., time spent around peers who use), family (e.g., sibling use), and neighborhood (i.e., perceived alcohol and drug problems in neighborhood). For each co-use combination (AC or TC), we estimated parallel process piecewise latent growth models in a structural equation modeling framework using Mplus v8. The final AC and TC co-use models included all predictor variables from the four domains. Increases in positive expectancies and time spent around peers who use AC, as well as steeper decreases in resistance self-efficacy, were all related to a greater likelihood of AC co-use in young adulthood. Increases in sibling TC use and time spent around peers who use TC, as well as steeper decreases in resistance self-efficacy, were all related to a greater likelihood of TC co-use in young adulthood. Overall, findings highlight the importance of addressing peer influence in prevention programming during both early and late adolescence.

Simultaneous trajectories of alcohol and cannabis use from adolescence to emerging adulthood: Associations with role transitions and functional outcomes

Alcohol and cannabis are the most widely used substances among young people. This study identifies alcohol and cannabis (AC) trajectory classes, and examines class differences on adult role transitions and functioning during emerging adulthood. Participants (n = 3,265) completed six annual surveys (ages 16 to 22) on frequency of past month alcohol and cannabis use. Parallel process growth mixture models (PP-GMM) were used to model simultaneous trajectories of use and identify latent trajectory classes based on AC co-use. Trajectory classes were compared on age 23 outcomes. Analyses identified four trajectory classes of co-use: Initial AC Abstainer with Increasing AC Use (85%); Initial Low AC Use with Increasing Drinking (5%); Increasing Cannabis Use with Steady Drinking (3%); and Decreasing Cannabis Use with Steady Drinking (7%). The two trajectory classes with early AC co-use were less likely to have made certain role transitions, and reported poorer functioning in emerging adulthood, but in distinct ways. For example, the Decreasing Cannabis Use with Steady Drinking class was less likely to graduate from college, and reported more AC consequences and related problems, whereas the Initial Low AC Use with Increasing Drinking class was less likely to be employed full-time, and reported poorer mental health. The Increasing Cannabis Use with Steady Drinking class tended to fall between the Initial AC Abstainer class and the two early AC co-use trajectory classes on outcomes. Results indicate the ways in which AC co-use can affect functional outcomes and the timing of role transitions during the transition to young adulthood.

Why Young Adults Obtain a Medical Marijuana Card: Associations with Health Symptoms and Heaviness of Use

Objective.

Prior studies documenting more frequent and problematic use among young adults who have acquired medical marijuana (MM) cards have broadly compared those who use medically to those who use recreationally. Gaining a better picture of how health symptoms and problematic use vary both within those who have a MM card for specific condition domains and between those who do not have a MM card can provide key information for medical practitioners and states interested in adopting or updating MM policies.

Method.

The current study categorizes young adults authorized to use MM into three mutually exclusive groups based on endorsements of qualifying conditions: (1) Physical Health only (e.g., AIDS, arthritis, cancer; n = 34); (2) Behavioral Health only (e.g., anxiety, depression, sleep problems; n = 75); and (3) Multiple Conditions (a physical and behavioral health condition; n = 71). Multiple and logistic regression models examined differences across marijuana use, problems, mental health, physical health, and sleep quality for MM condition categories and for those that only use marijuana recreationally (n = 1,015).

Results.

After adjusting for socio-demographic factors (age, sex, sexual orientation, educational status, employment status, race/ethnicity, mother’s education, prior intervention involvement in youth), MM card holders, particularly those with physical health or multiple health conditions, reported heavier, more frequent, and more problematic and risky marijuana use compared to those using recreationally. Despite this pattern, those in different MM condition categories were generally not found to be more symptomatic in domains of mental or physical health relevant to their respective conditions, compared to different category groups or to those using recreationally.

Conclusions.

Findings emphasize the importance of providers conducting a careful assessment of reasons for needing a card, along with use, to reduce potential harms while adding credibility to a medical movement with genuine promise of relief for many medical conditions.

Longitudinal associations of sleep problems with alcohol and cannabis use from adolescence to emerging adulthood

STUDY OBJECTIVES

This study examined longitudinal associations of sleep problems with alcohol and cannabis use across six annual waves of data from adolescence to emerging adulthood.

METHODS

Participants were 3,265 youth from California (ages 16 to 22 across waves). At each wave, past-month alcohol use and cannabis use, mental health, and several dimensions of sleep health (i.e., social jetlag, bedtimes, time in bed, trouble sleeping) were assessed via questionnaire. Parallel process latent growth models examined the association between sleep and alcohol or cannabis use trajectories and the role of mental health in contributing to such trajectories.

RESULTS

Smaller declines in social jetlag (r = .11, p = .04), increases in trouble sleeping (r = .18, p < .01), and later weekday (r = .16, p < .01) and weekend bedtimes (r = .25, p < .01) were associated with increases in likelihood of alcohol use over time. Declines in weekend TIB (r = -.13, p = .03), as well as increases in weekday TIB (r = 0.11, p = 0.04) and later weekday (r = .18, p < .01) and weekend bedtime (r = .24, p < .01), were associated with increases in likelihood of cannabis use over time. Most associations remained significant after controlling for time-varying mental health symptoms.

CONCLUSIONS

Trajectories of sleep health were associated with trajectories of alcohol and cannabis use during late adolescence to emerging adulthood. Improving sleep is an important target for intervention efforts to reduce the risk of substance use during this critical developmental transition.

Risk and Resilience Factors in Urban American Indian and Alaska Native Youth during the Coronavirus Pandemic

American Indians and Alaska Natives suffer disproportionately from poverty and other inequities and are vulnerable to adverse health and socioeconomic effects of COVID-19. Using surveys and interviews (May - July 2020), we examined urban American Indian/Alaska Native adolescents' (N=50) health and behaviors, family dynamics, community cohesion, and traditional practice participation during COVID-19. About 20% of teens reported clinically significant anxiety and depression, 25% reported food insecurity, and 40% reported poor sleep. Teens also reported high family and community cohesion, and many engaged in traditional practices during this time. Although many teens reported problems, they also emphasized resilience strategies.

Tobacco/nicotine and marijuana co-use motives in young adults: Associations with substance use behaviors one year later

Co-administration of tobacco/nicotine and marijuana (e.g., using both products on the same occasion by mixing them in the same delivery device) is a risky, yet common, form of co-use among young adults. Understanding motivations for co-administration co-use, and how these are associated with subsequent use and related problems, is needed to inform policy, prevention, and intervention efforts. We conducted a latent class analysis on 342 young adults with past-year co-administration of tobacco/nicotine and marijuana to determine how emergent classes of 16 co-use motives were associated with use and co-administration co-use of tobacco/nicotine and marijuana one year later. Four classes emerged: (1) a high all class that reported high endorsement of all motives, (2) a high coping class that reported high endorsement of co-use due to coping with stress and bad moods, (3) a high social/physiological reinforcement class that reported low endorsement of coping but high probability of social and relaxation motives and motives to even out effects of each substance, and (4) a low all class that reported low endorsement of all motives. The high all and high coping classes reported greater frequency and quantity of single substance use and co-administration. The high coping class reported more marijuana consequences than the low all class. The high all and high coping classes reported younger age of initiation of each individual substance and co-administration. Considering co-use motives may be useful in identifying those at highest risk for future use and consequences and tailoring interventions to the distinct needs of co-use subgroups.
