Preventing alcohol use with a voluntary after-school program for middle school students: results from a cluster randomized controlled trial of CHOICE

Discrimination experiences and problematic alcohol and cannabis use in young adulthood

BACKGROUND AND OBJECTIVES

Limited research has examined how discrimination in young adulthood relates to substance use. We examined how multiple and specific types (e.g., race-based) of experiences of unfair treatment are related to problematic alcohol and cannabis use.

METHODS

We analyzed cross-sectional data from a diverse cohort of young adults (mean age 24.7) predominantly residing in southern California (n = 2303) to examine associations of multiple (count) and specific experiences (race-, sexual orientation-, gender-based) of perceived everyday discrimination with self-reported alcohol and cannabis use outcomes (consequences, use disorders, and solitary use). We also tested interactions between the three specific discrimination experiences and sociodemographic characteristics (e.g., race-based discrimination × race/ethnicity).

RESULTS

In this diverse sample (e.g., 47% Latinx/o and 22% Asian; 22% sexual/gender diverse; 56% female) of young adults, about 46% reported up to four different discrimination experiences and 27% reported race-, 26% gender-, and 5% sexual orientation-based discrimination. Race- and gender-based discrimination and experiencing more types of discrimination were associated with worse cannabis use outcomes. Race-based discrimination was associated with fewer alcohol consequences and lower Alcohol Use Disorders Identification Test (AUDIT) scores. Associations with sexual orientation-based discrimination and the interactions were not significant.

DISCUSSION AND CONCLUSIONS

Findings build on limited research on associations of discrimination with cannabis use in young adults. More work is needed to understand the mechanisms by which discrimination influences drinking behaviors.

SCIENTIFIC SIGNIFICANCE

This study advances the field by examining the unique contributions of specific and multiple types of discrimination experiences in young adulthood, a critical developmental period in which substance use peaks.

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.

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.

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.

Developing a text-message library for tobacco prevention among adolescents: A qualitative study

INTRODUCTION

Communicating the risks associated with nicotine and tobacco use to adolescents can be challenging, especially with the current tobacco market's attempt to capture the attention of youths. Text message interventions have emerged to address the need to improve tobacco risk communication. This article informs the design of a message library for tobacco risk communication that is based on the transtheoretical model and addresses the risk of multiple tobacco products.

METHODS

We draw findings from this study from two phases. Phase 1 involved six remote focus group discussions (n = 25) and an in-depth interview, and Phase 2 involved online ideation sessions (n = 11) that led to the current version of the messages. We conducted the study within a larger project for the design and testing of a tobacco prevention program. With thematic analysis and the affinity mapping technique, two research team members identified repeated topics and relevant quotes to organize them into themes and subthemes.

RESULTS

In Phase 1, thematic analysis revealed four major themes: 1) Adolescents' gap in tobacco knowledge, 2) Social influence and popularity, 3) Attitude toward marketing, and 4) Text message framing preferences. During Phase 2, participants generated 1-to-7 iterations of the original messages. Votings and discussions resulted in a library of 306 messages under 7 sections, categorized based on the processes of change from the transtheoretical model.

CONCLUSION

The current study presents key insights crucial for developing and evaluating a library of tobacco prevention text messages that is scientifically valid and successfully resonates with today's adolescents. Our future plan is to go beyond this initial message development and vet the message library by adolescents and expert reviewers in tobacco risk communication. Future research may consider developing messages that are tailored based on gender, ethnicity, and other factors that are predictive of tobacco use.

Directional associations between posttraumatic stress disorder symptoms and cannabis use in young adults: Uncovering variation by sex, race, and ethnicity

OBJECTIVE

Prevalence rates of cannabis use and PTSD vary, with men reporting greater cannabis use than females, females reporting higher rates of PTSD than males, and race and ethnic minority persons reporting higher rates of both cannabis and PTSD compared to non-Hispanic White individuals. This study extends our understanding of directional associations between cannabis use and PTSD from early to late young adulthood (18-26 years old) using two theoretical models: symptom-driven pathway and substance-induced pathway.

METHOD

Participants provided yearly data for 14 years, and the present study utilized data from Waves 9 through 14. Those endorsing Criterion A in at least one wave of data collection (n = 1,454) were included in the analytic sample. We used autoregressive latent trajectory with structured residuals to understand reciprocal associations for the full sample, as well as by sex and race or ethnicity.

RESULTS

For the full sample, we noted support for both symptom-driven and substance-induced pathways during early young adulthood (18-20) but only support for a symptom-driven pathway during late young adulthood (21-26). Males showed the same pattern as the full sample; however, for females, only a symptom-driven pathway during late young adulthood was found. For race and ethnic minority participants, we showed full cross-lagged effects during both early and late young adulthood and no associations for non-Hispanic White individuals.

CONCLUSIONS

Results indicate that both men and individuals from minoritized racial and ethnic groups are more likely to report heightened PTSD symptomology, maladaptive coping, and worsening symptoms. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Examining indirect effects of advertising exposure on young adults' cannabis and nicotine vaping

OBJECTIVE

To examine longitudinal associations between exposure to two types of advertisements (medical/recreational cannabis and e-cigarette retailers [vape shops]) and young adults' cannabis and nicotine vaping behavior. Positive and negative expectancies for cannabis and vaping nicotine were examined as mediators of these associations.

METHOD

Secondary analysis of observational data from a longitudinal cohort of young adults recruited from Southern California (Wave 13: N = 2,411, 56% female, Mage = 23.6). Participants completed web-based surveys annually, reporting on advertising exposure in 2018, expectancies in 2019, and cannabis and nicotine vaping in 2020. Two path models were specified: (a) of past-month cannabis vaping only, nicotine vaping only, and co-use (vs. no vaping) and (b) of single product vaping (vs. co-use). Path analyses modeled direct and indirect associations between variables.

RESULTS

Controlling for past-month cannabis and nicotine use and other covariates, there were no significant direct associations of advertising exposure with cannabis and/or nicotine vaping. However, the association between cannabis advertising exposure and vaping (cannabis only) was significantly mediated by positive cannabis expectancies (β = 0.02, SE = 0.01, p = .03). Among those who vaped cannabis and/or nicotine in the past month at Wave 13, expectancies did not significantly mediate associations between advertising exposure and single product use (vs. co-use).

CONCLUSIONS

Although exposure to cannabis advertisements may not be directly associated with young adults' cannabis vaping 2 years later, the effects of advertising exposure may be exerted indirectly by increasing positive beliefs about cannabis. Implications for public health policy are discussed. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

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.

Identifying adolescents' gaming preferences for a tobacco prevention social game: A qualitative study

INTRODUCTION

Considering the dangers of adolescent tobacco use, the successful design of behavioral programs is crucial for tobacco prevention. According to preliminary research, social game interventions can improve adolescent tobacco outcomes. The current qualitative study aims to (1) uncover the gaming elements that adolescents deem important for a positive learning experience, and (2) confirm these gaming elements with adolescents who are presented with a tobacco prevention game concept that applies these elements.

METHODS

Findings from this study are drawn from two phases. Phase 1 involved in-person focus group discussions (n = 15) and Phase 2 included three online focus groups and a paired interview with another set of adolescents (n = 15). The study was conducted under a project that aimed to design and test a social game-based tobacco prevention program for adolescents (Storm-Heroes). With open coding and thematic analysis, two research team members identified repeated topics and relevant quotes to organize them into themes. The themes evolved as new content was identified during the process. This process was repeated until thematic saturation was reached.

RESULTS

Thematic analysis across Phase 1 and Phase 2 revealed four major themes: 1) Balance during gaming challenges, 2) Healthy social interaction, 3) Performance and creative freedom, and 4) Fictional world and game mechanics for tobacco prevention.

CONCLUSION

This study identified specific intervention features that best fit the needs of adolescents in the context of a social game for tobacco prevention. For future research, we will use a participatory approach to allow adolescents to take part in the design process, improve Storm-Heroes, and develop health promotional messages that can be incorporated into the program. Ultimately, a board game for tobacco prevention is expected to bring adolescents together to create lasting memories that nudge them away from tobacco use and the harm it can cause.

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.

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.

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.

Differential item functioning of the Acculturation, Habits, and Interests Multicultural Scale for Adolescents (AHIMSA) by race/ethnicity

Background

Acculturation is a complex multidimensional construct that plays in important role in various outcomes across many domains (e.g., psychological, behavioral, social, and developmental). While there are many acculturation measures for specific racial/ethnic groups, few multigroup measures exists. Even fewer have been psychometrically evaluated for differential item functioning (DIF; e.g., measurement invariance). This is a critical step in determining whether item properties are equivalent across groups and thus, whether scores obtained from different groups are in fact comparable.

Methods

The Acculturation, Habits, and Interests, Multicultural Scale for Adolescents (AHIMSA) was completed by first and second generation participants identifying as White, Hispanic, or Asian (n = 1,399). The scale can be used to compute scores on four acculturation orientation subscales: Assimilated, Separated, Integrated, and Marginalized. Racial/ethnic DIF was evaluated for the Assimilation, Integration, and Separation subscales.

Results

Analyses revealed racial/ethnic DIF was present for two items on the Separation scale based on McFadden's pseudo R2. No DIF was identified for the Assimilation and Integration scales. Supplemental analyses revealed no evidence of longitudinal DIF or by generation status and some DIF by sex for Assimilation and Integration. Based on evaluation of test characteristic curves and DIF plots, it was determined that DIF was trivial and could likely be ignored.

Conclusions

Psychometric properties were generally equivalent across the three racial/ethnic groups for each of the subscales evaluated. This indicates that scores obtained from each subscale could be compared across racial/ethnic groups. By establishing cross-group usability of the scale, racial/ethnic differences in acculturation orientation can be examined, and, more importantly, used in the context of research on related mental, physical, and behavioral health outcomes.

Culturally enhancing a group-based motivational interviewing substance use prevention program for Latine youth

Background

Group Motivational Interviewing for Teens (GMIT) has been effective in reducing youth substance use in diverse communities, yet more research is needed to determine its efficacy in reducing tobacco and alternative tobacco products (ATP) use among Latine adolescents. This study modified GMIT to include a focus on ATPs (GMIT-ATP). GMIT was also linguistically translated so it could be offered in English and Spanish, culturally enhanced, and parent sessions were added (GMIT-ATP + P).

Methods

The study's aims were to 1) Develop a model of how cultural context, family relationships, and adolescent tobacco-related skills/beliefs are associated with smoking and ATP use; 2) Examine the impact of the GMIT-ATP intervention on adolescent tobacco use; 3) Examine whether the GMIT-ATP + P intervention improves family/parenting factors associated with reduced adolescent tobacco use; 4) Examine whether GMIT-ATP + P is more effective than GMIT-ATP in improving adolescent tobacco use; 5) Explore whether essential components of our behavior change model mediate the impact on tobacco use, and 6) Explore whether cultural factors influence the impacts of our intervention. Latine adolescents (ages 10-16) and their parents/guardians were recruited throughout Virginia. Parents and adolescents completed three surveys: before and immediately after the program ends and at 3-months post-intervention. Families attended 3 GMIT-ATP or GMIT-ATP + P sessions.

Conclusion

Findings from this study will be disseminated in Latine communities and with providers working with Latine youth and can serve as a community-based model to reduce substance and tobacco use (e.g., ATP) in these Latine communities.

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.

Developmental trajectories of tobacco use and risk factors from adolescence to emerging young adulthood: a population-based panel study

BACKGROUND

Adolescence to young adulthood is a critical developmental period that determines lifelong patterns of tobacco use. We examined the longitudinal trajectories of tobacco use, and risk factors for its use, and explored the association between the trajectories of mobile phone dependency and smoking throughout the life-course among adolescents and young adults.

METHODS

Data of 1,723 subjects (853 boys and 870 girls) were obtained from six waves of the Korean Children and Youth Panel Survey (mean age = 13.9-19.9 years). To identify trajectories of smoking and mobile phone dependency, group-based trajectory modelling (GBTM) was conducted. A multinomial logistic regression analysis was performed to identify the characteristics of the trajectory groups.

RESULTS

GBTM identified four distinct smoking trajectories: never smokers (69.1%), persistent light smokers (8.7%), early established smokers (12.0%), and late escalators (10.3%). Successful school adjustment decreased the risk of being an early established smoker (odds ratio [OR] 0.46, 95% confidence interval [CI] 0.27-0.78). The number of days not supervised by a guardian after school was positively associated with the risk of being an early established smoker (OR 1.96, 95% CI 1.23-3.13). Dependency on mobile phones throughout the life-course was positively associated with the risk of being a persistent light smoker (OR 4.04, 95% CI 1.32-12.34) or early established smoker (OR 8.18, 95% CI 4.04-16.56).

CONCLUSIONS

Based on the group-based modeling approach, we identified four distinctive smoking trajectories and highlight the long-term effects of mobile phone dependency, from early adolescence to young adulthood, on smoking patterns.

Late Adolescent Predictors of Homelessness and Food Insecurity During Emerging Adulthood

PURPOSE

Economic instability is a significant and growing problem among emerging adults in the U.S. This study identifies adolescent factors across multiple levels of influence that predict homelessness and food insecurity 5 years later.

METHODS

The analytic sample (n = 2,110) completed a survey in 2015-2016 (mean age 17) that assessed a range of demographic, behavioral health, family, peer, academic, and neighborhood factors, and a follow-up survey in 2019-2020 (mean age 23) that assessed past-year homelessness and food insecurity. Logistic regression analyses were conducted for the full sample, and by race/ethnicity.

RESULTS

At follow-up, 7.5% of participants reported homelessness, and 29.3% reported food insecurity. Multivariate analyses indicated that only adverse childhood experiences and weaker academic orientation predicted both outcomes. Future homelessness was additionally predicted by greater exposure to substance using peers during adolescence. Identifying as Hispanic, lower maternal education, and greater neighborhood disorganization were risk factors for future food insecurity, and living with both biological parents and better mental health were protective factors. Race/ethnicity stratified models showed variations in multilevel predictors of both outcomes, except for adverse childhood experiences, which were significant across all subgroups.

CONCLUSIONS

Adverse childhood experiences and weaker academic orientation emerged as the most robust predictors of economic instability in emerging adulthood. However, a range of other modifiable multilevel predictors in adolescence were identified that were unique to homelessness or food insecurity and that varied by race/ethnicity. Results suggest the need for multilevel approaches early in life to reduce risk of economic instability during emerging adulthood.

Young Adults' Perceived Impact of COVID-19 Pandemic on Sleep and Other Functioning: Does It Differ for Sexual/Gender and Racial/Ethnic Minorities?

OBJECTIVES

Since the beginning of the COVID-19 pandemic, there has been concern that the pandemic and associated mitigation efforts would have a particularly adverse effect on communities that are marginalized. This study examined disparities in the perceived impacts of the pandemic on sleep, mental and physical health, social functioning, and substance use among young adults based on sexual/gender minority (SGM) status and race/ethnicity.

METHOD

Participants were 2,411 young adults (mean age = 23.6) surveyed between July 2020-July 2021. A linear regression analysis tested SGM and racial/ethnic group differences on 17 outcomes.

RESULTS

Most young adults reported little-to-no effect of the pandemic on sleep or other indicators of health and functioning. However, SGM young adults reported more adverse effects than non-SGM young adults on their sleep and most other outcomes. Hispanic young adults reported shorter sleep duration - but less pandemic-related depression, loneliness, and relationship problems - compared to non-Hispanic white young adults. We found no evidence that young adults with multiple minority statuses had especially poor pandemic-related outcomes.

CONCLUSIONS

While most young adults did not perceive much impact of the pandemic, results highlight disparities across certain demographic subgroups that may need to be addressed through targeted interventions and close monitoring for long-term effects.

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.

Disparities in functioning from alcohol and cannabis use among a racially/ethnically diverse sample of emerging adults

BACKGROUND

Trajectory studies have consistently shown that alcohol and cannabis (AC) use during emerging adulthood (EA) affect functioning; however, few studies examine whether racial/ethnic disparities may occur at similar levels of use.

METHODS

We conducted web-based surveys across five waves from mean age 18.3 through 22.6. The sample (N = 2945) is 55% female, 46% Hispanic, 23% Asian, 23% White, 6% multi-racial (MR)/other, and 2% Black.

MEASUREMENTS

Past month substance use was defined as number of days used. Outcomes at age 22.6 included negative consequences, delinquency, physical ailments and health, depression and anxiety, peer relationship functioning, life satisfaction, employment, and education.

RESULTS

Compared to White EAs, Hispanic, Asian, and MR/other EAs reported less initial alcohol use; Hispanic and Asian EAs reported less initial cannabis use, whereas Black EAs reported more cannabis use. Greater initial frequency and increased frequency of AC use were associated with poorer outcomes (e.g., worse mental health). In terms of disparities, compared to White EAs, Hispanic EAs reported poorer physical health at the same levels of AC use; Hispanic, Asian, and MR/other EAs reported greater alcohol consequences and delinquency; Black, Hispanic, Asian and MR/other EAs reported lower life satisfaction; and Hispanic and MR/other EAs were less likely to pursue education beyond high school (although Asian EAs were more likely).

CONCLUSIONS

Findings emphasize that trajectories of AC use during EA are associated with a range of functional outcomes. Disparities in functioning at similar levels of AC use highlight the importance of reaching racially/ethnically diverse EAs with prevention and intervention programming.

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.

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 and Cannabis Use Trajectories and Outcomes in a Sample of Hispanic, White, and Asian Sexual and Gender Minority Emerging Adults

Substance use disproportionately affects health and psychosocial outcomes for some racial/ethnic groups, but few longitudinal studies examine the extent to which sexual and gender minority (SGM) emerging adults of different racial/ethnic groups may experience disparities in outcomes at similar levels of alcohol or cannabis use. This study used five waves of annual survey data (spanning 2015 (average age 18) to 2020 (average age 23)) from an ongoing longitudinal cohort study of emerging adults. In the subset of 359 SGM emerging adults, separate sequelae of change models assessed differences in trajectories of alcohol or cannabis use (past 30-day frequency) and multiple health and psychosocial outcomes across Hispanic, Asian, and White individuals. White SGM emerging adults showed higher baseline levels of alcohol and cannabis frequency compared to Hispanic and Asian peers, but all groups showed similar rates of change (slope) over time. We observed few racial/ethnic differences in SGM emerging adult outcomes at the same levels of alcohol or cannabis use; that is, racial/ethnic groups showed similar patterns on most health and psychosocial outcomes; however, some differences emerged. For example, Asian respondents reported less engagement in sex with casual partners after using alcohol, marijuana, or other drugs compared to their White peers, at the same levels of alcohol use (β = −0.579, p = 0.03) or cannabis use (β = −0.737, p = 0.007). Findings underscore a need to consider multiple outcome domains and factors beyond additive stress in examining the effects of substance use across different groups of SGM individuals. More longitudinal studies with large, contemporary, and diverse samples of SGM emerging adults are needed to better characterize similarities and differences in patterns of substance use and use-related consequences in relation to intersecting SGM, racial/ethnic, and other identities.

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.

Do Recent Experiences of Sexual Violence and Co-Occurring Depression and Anxiety Symptoms Predict Poorer Functioning One Year Later During the Transition to Young Adulthood?

Sexual violence (SV) is a public health concern for youth. Few longitudinal studies address how experiences of SV and co-occurring depression and anxiety symptoms in early young adulthood may contribute to poorer functioning in young adulthood. Using a sample of 2,416 youth aged 18 to 20 (Time 1), we assessed past year SV and co-occurring depression and anxiety symptoms. One year later, when youth were between the ages of 20 and 22 (Time 2), participants indicated their functioning in four domains: physical health and sleep quality, substance use consequences, psychological functioning, and social functioning. Using latent class analyses, we found six participant classes at Time 1 based on SV experiences and co-occurring depression and anxiety symptoms. Classes were variable by participants' reported degree of SV experiences and co-occurring depression and anxiety symptomology. Longitudinal analyses indicated that youth in a class that experienced high levels of both SV and co-occurring depression and anxiety at Time 1 generally reported the poorest functioning in all key domains at Time 2. However, classes where participants reported greater depression and anxiety symptoms-most often in the presence of, but at times in the absence of, SV-were consistently associated with poorer functioning for physical health, psychological functioning, and social health. Classes where participants reported greater SV-in the presence of, but at times in the absence of, depression and anxiety symptoms-were associated with greater alcohol and marijuana consequences. Findings suggest prevention of SV, accessible counseling for those that have experienced SV, and screening to identify and intervene to address depression and anxiety may all be essential to help prevent poorer functioning in young adulthood.

Selection versus socialization effects of peer norms on adolescent cigarette use

Adolescent smokers tend to have friends who also smoke. This association has been attributed to peer socialization and peer selection effects. However, evidence regarding timing and relative magnitude of these effects is mixed. Using a random-intercept cross-lagged panel model, we examined the reciprocal relations between adolescent cigarette use and perceptions of friends' cigarette use in a sample of 387 adolescents, assessed annually for 4 years. Adolescent cigarette use predicted increases in perceived friend use before the reverse effect emerged. Further, some of the effect of early adolescent cigarette use on subsequent use was mediated by changes in perceived friend use. The results support a greater role for friend selection than socialization in predicting early adolescent cigarette use.

Debunking the myth of low behavioral risk among Asian Americans: The case of alcohol use

BACKGROUND AND PURPOSE

Asian Americans (AAs) are the fastest-growing ethnic group in the United States. There is a paucity of research on alcohol-related problems among AAs. However, alcohol use and misuse are a growing concern within this population and are associated with adverse health and mental health consequences.

METHODS

Using data from the 2015-2018 National Survey on Drug Use and Health (NSDUH), we examined the prevalence, psycho-social-behavioral correlates, and gender differences in drinking, binge drinking, and alcohol use disorder (AUD) among AA adolescents and adults. We also estimated the prevalence of binge drinking and AUD by country of origin and nativity.

RESULTS

Older adolescents (15-17) had the highest prevalence of past-month drinking (8.00%), binge drinking (4.3%), and AUD (1.8%). Among AA adults, the highest rates of binge drinking (23.0%) and AUD (7.2%) were observed among young adults ages 18-25. The highest rates of binge drinking and AUD were observed among US-born Korean Americans (binge drinking: 26.9%, AUD: 13.1%) and US-born Filipino Americans (binge drinking: 25.9%, AUD: 6.2%).

CONCLUSIONS

Contrary to the common perception that AA is a low-risk group for alcohol problems, we found that AA young adults, US-born Korean, Filipino, and Indian Americans have a high risk for drinking, binge drinking, and/or AUD. We also identified risk and protective factors against alcohol use/misuse among AAs. Preventions and interventions that incorporate the important risk/protective factors for AAs using a culturally sensitive approach are needed.

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.

Do Alcohol Prevention Programs Influence Adolescents' Drinking Behaviors? A Systematic Review and Meta-Analysis

This study analyzed the effects of various alcohol prevention programs on the drinking behavior of adolescents. There were seven electronic databases used for the literature search. A systematic review and meta-analysis are employed for works published in Korean and English from January 2010 to April 2021, with strict inclusion criteria yielding 12 papers in the review. The type of alcohol prevention interventions included educational and motivational interventions. Six studies had more than 500 participants each, and five studies had more than 10 participating schools. The programs did not effectively reduce the frequency of drinking or binge drinking of adolescents but significantly reduced the amount of alcohol consumed. Based on the results of this study, when planning alcohol prevention programs for adolescents, it is necessary to adopt a multi-level approach, including the engagement of parents and the community.

"What We Have Here, Is a Failure to [Replicate]": Ways to Solve a Replication Crisis in Implementation Science

Adapting the classic line from the 1967 film Cool Hand Luke, the title is meant to convey that implementation science (IS), like other fields, has not been embracing replication studies, which is a key component to the open science movement. The purpose of this article is to review what is known about replication of implementation trials and identify the gaps and next steps to continue increasing the transparency, openness, and replicability of implementation research. After presenting an overview of study replication and how it is a key component of open science, the article will examine how replication of implementation studies has (or more accurately has not) been approached in IS. As will be discussed, replication in IS shares some challenges with studies that attempt to replicate interventions, but also presents unique challenges. This article discusses different types of replications (e.g., direct vs. conceptual) and how they can benefit the field of IS. The article then presents a specific example of an implementation strategy called Getting To Outcomes© to describe how to design a replication study and interpret the results. The article ends with multiple options implementation scientists could consider to improve the likelihood and quality of replication studies. The discussion also envisions how implementation science can enable researchers and practitioners to work together in real-world contexts to encourage wide replication of implementation studies and advance the goal of improving public health.

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.

A Latent Class Analysis of Prevention Approaches Used to Reduce Community-Level Prescription Drug Misuse in Adolescents and Young Adults

The Substance Abuse and Mental Health Services Administration's Strategic Prevention Framework Partnerships for Success (PFS) program supports community-based organizations (CBOs) across the United States in implementing evidence-based prevention interventions to reduce substance use in adolescents and young adults. Little attention has been paid to how CBOs combine interventions to create comprehensive community-specific prevention approaches, or whether different approaches achieve similar community-level effects on prescription drug misuse (PDM). We used PFS evaluation data to address these gaps. Over 200 CBOs reported their prevention intervention characteristics, including strategy type (e.g., prevention education, environmental strategies) and number of unique interventions. Evaluation staff coded whether each intervention was an evidence-based program, practice, or policy (EBPPP). Latent Class Analysis of seven characteristics (use of each of five strategy types, use of one or more EBPPP, and number of interventions implemented) identified six prevention approach profiles: High Implementation EBPPP, Media Campaigns, Environmental EBPPP, High Implementation Non-EBPPP, Prevention Education, and Other Information Dissemination. All approaches except Media Campaigns and Other Information Dissemination were associated with significant reductions in community-level PDM. These approaches may need to be paired with other, more direct, prevention activities to effectively reduce PDM at the community level. However, similar rates of change in PDM across all 6 prevention approaches suggests only weak evidence favoring use of the other four approaches. Community-based evaluations that account for variability in implemented prevention approaches may provide a more nuanced understanding of community-level effects. Additional work is needed to help CBOs identify the most appropriate approach to use based on their target communities' characteristics and resources.

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.

Correlates of Awareness and Use of Heated Tobacco Products in a Sample of US Young Adults in 2018-2019

INTRODUCTION

Tobacco companies have devoted increased resources in recent years to developing and marketing heated tobacco products (HTPs) as alternatives to combustible products like cigarettes. However, little is known about correlates of awareness and use of these products in American young adults.

METHODS

Two thousand four hundred ninety-seven young adults (mean age = 21.6) completed survey items on HTP awareness and lifetime use in 2018-2019. Logistic regression models compared young adults who were (1) unaware of HTPs (reference group) with those who were, (2) aware of HTPs, and (3) had ever used HTPs on demographic, tobacco, and other substance use characteristics. Among current smokers, these groups were compared on cigarette use, dependence, and readiness to quit.

RESULTS

Approximately 12% of respondents (n = 293) were aware of HTPs, and 5% (n = 134) reported lifetime HTP use. Controlling for demographics, HTP awareness and use were both associated with greater use of all types of tobacco products, number of different tobacco products, and use of marijuana and other drugs. Among current smokers, HTP awareness and use correlated with heavier cigarette consumption, greater dependence, and past-month marijuana use, but not with recent quit attempts or thinking about quitting cigarettes.

CONCLUSIONS

Awareness and use of HTPs among young adults were associated with greater use of tobacco products and other substances and, among current smokers, with greater cigarette dependence (but not cessation-related factors). As these products become increasingly available in the United States, additional surveillance and monitoring activities are needed to better understand use patterns, consequences, and reasons for using HTPs.

IMPLICATIONS

Few studies have examined factors associated with awareness and use of heated tobacco products (HTPs) among US young adults. HTP awareness and lifetime use correlated with a range of factors, including male gender, white race/ethnicity, and tobacco and other substance use. Lifetime use of HTPs was low (5%); most lifetime HTP users reported history of other tobacco use, but a sizeable minority (14%) reported no other tobacco product use history. Among current cigarette smokers, cigarette dependence, poly-tobacco use, and marijuana use-but not cigarette cessation attempts or contemplation-were associated with greater likelihood of awareness and use of HTPs.

Opioid misuse during late adolescence and its effects on risk behaviors, social functioning, health, and emerging adult roles

Opioid misuse has emerged in recent years as a major public health concern in the United States, particularly for adolescents and emerging young adults. We examined the association of opioid misuse from ages 18 to 20 with four domains at age 21-22: risk behaviors and consequences; health; social functioning; and emerging adult roles. Participants were surveyed annually from 2008 through 2019. The sample includes N = 2880 youth from waves 8-11. The sample was approximately 18 years old at wave 8; 54% female, 46% Hispanic, 20% white, 20% Asian, 2% Black, and 11% multiracial. Opioid misuse was low in this general sample of young adults, with about 4% reporting misuse from age 18-20. We used latent growth curve modeling to examine how misuse from ages 18-20 was associated with functioning at age 21-22. Adolescents who reported opioid misuse at age 18 also reported more negative consequences from alcohol and cannabis use and greater odds of other prescription drug misuse at age 21-22 than those with no misuse. Those reporting opioid misuse at age 18 were also more likely to engage in sexual risk behaviors, report delinquent behavior, and have a higher likelihood of experiencing sexual victimization and engaging in sexual perpetration at age 21-22 than those with no misuse. Neither the intercept nor slope of opioid misuse was associated with depression, anxiety, physical health or ailments, satisfaction with friends, romantic relationship functioning, or emerging adult roles at wave 11. Findings highlight the importance of screening and brief intervention for adolescents reporting opioid misuse.

Recruitment and retention in randomized controlled trials with urban American Indian/Alaska Native adolescents: Challenges and lessons learned

BACKGROUND

Although the majority of American Indians/Alaska Natives reside in urban areas, there are very few randomized controlled trials analyzing culturally centered substance use prevention interventions for this population.

METHODS

We describe methods employed to recruit and retain urban American Indian/Alaska Native adolescents into a randomized controlled trial, which was focused on testing the potential benefits of a substance use prevention intervention for this population. We also report challenges encountered in recruitment and retention of participants and strategies employed addressing these challenges. Data collection occurred from August 2014 to October 2017.

RESULTS

We partnered with two community-based organizations in different cities in California. We utilized American Indian/Alaska Native recruiters from communities, placed flyers in community-based organizations, and asked organizations to post flyers on their web and social media sites. We also offered gift cards for participants. Our initial recruitment and retention model was moderately successful; however, we encountered five main challenges: (1) transportation, (2) increasing trust and interest, (3) adding research sites, (4) getting the word out about the project, and (5) getting youth to complete follow-up surveys. Strategies employed to overcome transportation challenges included shortening the number of sessions, offering sessions on both weekends and weekdays, and increasing bus tokens and transportation options. We hired more staff from American Indian/Alaska Native communities, added more research sites from our previously established relationships, and were more proactive in getting the word out on the project in American Indian/Alaska Native communities. We also utilized more field tracking and emailed and mailed survey invitations to reach more participants for their follow-up surveys. Because of our efforts, we were nearly able to reach our initial recruitment and retention goals.

CONCLUSION

Although our research team had previously established relationships with various urban American Indian/Alaska Native communities, we encountered various recruitment and retention challenges in our study. However, by identifying challenges and employing culturally appropriate strategies, we were able to collect valuable data on the potential effectiveness of a substance use prevention intervention for urban American Indian/Alaska Native adolescents. Findings from this study assist toward the development of potentially successful strategies to successfully recruit and retain urban American Indian/Alaska Native adolescents in randomized controlled trials.

Examining Associations Between Licensed and Unlicensed Outlet Density and Cannabis Outcomes From Preopening to Postopening of Recreational Cannabis Outlets

BACKGROUND AND OBJECTIVES

To expand on epidemiologic studies examining associations between the legalization of recreational cannabis and use among young adults, we examined the associations between licensed and unlicensed cannabis outlet density and cannabis outcomes.

METHODS

A total of 1097 young adults aged 21 and older living in Los Angeles County were surveyed before licensed recreational cannabis outlets opened (Time 1: July to December 2017) and after (Time 2: July 2018 to June 2019). Using a database of open licensed and unlicensed cannabis retailers to calculate individual-level cannabis outlet density measures, we examined associations between outlet density within a 4-mile radius of participants' residences with Time 2 outcomes of any past-month use, daily use, intentions to use, quantity used, consequences, and cannabis use disorder (CUD) symptoms.

RESULTS

After controlling for demographic factors and cannabis outcomes at a time point prior to their opening (Time 1), licensed cannabis outlets were associated with young adults' cannabis use, heavy use, and intentions, and unlicensed outlets were associated with young adults' heavy cannabis use and CUD symptoms.

CONCLUSION AND SCIENTIFIC SIGNIFICANCE

This study expands beyond studies of outlet prevalence to find that, after controlling for outcomes 1 year prior, licensed and unlicensed outlets were associated with young adults' cannabis outcomes. The current study is among the first to find associations between cannabis use outcomes and density of cannabis outlets among young adults using data from two time points: preopening and postopening of recreational cannabis retailers. Findings can inform policies around the density and placement of cannabis outlets. (Am J Addict 2020;00:00-00).

How do college students use their free time? A latent profile analysis of leisure activities and substance use

College is a critical period of transition to independence and the substantial amount of time that students have to participate in leisure activities may be conducive to substance use. However, little is known about the associations between leisure activities and substance use over time, or whether these associations differ by residential status (i.e., living with parents vs. on their own). Using latent profile analysis, this study found six distinct profiles of leisure activity participation in a racially/ethnically diverse sample of college students (N=1,207). Overall, profiles with medium levels of leisure activity participation were associated with more alcohol use, heavy drinking, and marijuana use one year later; whereas profiles with the lowest levels of leisure activity participation were associated with more cigarette use one year later. Identifying mechanisms through which leisure activities influence substance use can help inform prevention efforts to either reduce risks associated with participation or support protective effects.

Longitudinal Effects of Gendered Harassment Perpetration and Victimization on Mental Health Outcomes in Adolescence

Gendered harassment, including sexual harassment and homophobic name-calling, is prevalent in adolescents and is linked to negative outcomes including depression, anxiety, suicidality, substance abuse, and personal distress. However, much of the extant literature is cross-sectional and rarely are perpetrators of these behaviors included in studies of outcomes. Therefore, the current study examined the effects of longitudinal changes in gendered harassment perpetration and victimization on changes in mental health outcomes among a large sample of early adolescents. Given that these behaviors commonly occur in the context of a patriarchal society (males hold power), we also investigated the impact of gender on gendered harassment. Participants included 3,549 students from four Midwestern middle schools (50.4% female, 49% African American, 34% White) at two time points (13 and 17 years old). Results indicated that increases from age 13 to 17 years in sexual harassment perpetration and victimization and homophobic name-calling perpetration and victimization predicted increases in depression symptoms and substance use. Gender did not moderate these pathways. These findings highlight that negative outcomes are associated with changes in gendered harassment among adolescents and emphasize the importance of prevention efforts. Implications for school interventions are discussed.

Sources of cannabis among young adults and associations with cannabis-related outcomes

BACKGROUND

The ways in which young people learn about cannabis product availability and where they obtain cannabis products are important to understand for prevention and intervention efforts.

METHODS

Young adults who reported past month cannabis use (N = 758) completed an online survey in 2018-2019 on how they obtained cannabis and the products they used in a newly legalized market in Los Angeles (mean age 21.6; 44% Hispanic, 27% white, 15% Asian).

RESULTS

Overall, 59.1% obtained cannabis from recreational cannabis retailers (RCRs), 51.5% from family or friends, 39.1% from medical cannabis dispensaries (MCDs), and 5.5% from strangers or dealers in the past month. Compared to those getting cannabis from family or friends, those getting cannabis from MCDs or RCRs spent more money, used more cannabis products, were more likely to use alone, used greater quantities of bud/flower, and reported more consequences from use. Further, those obtaining cannabis from MCDs were more likely to screen positive for cannabis use disorder (CUD). For type of products, those obtaining cannabis from MCDs or RCRs were more likely to use joints, bongs, pipes, dabs, vape, and consume edibles relative to those obtaining from family or friends. Subgroup differences were found for both source patterns and cannabis-related outcomes. Males and those with a cannabis medical card reported spending more money on cannabis, using more types of products, and indicated more frequent use and greater CUD symptoms and consequences. Compared to Whites, Blacks spent more money on cannabis and used more products, and Hispanics reported using more products and greater quantities of cannabis bud/flower.

CONCLUSIONS

Findings highlight the different ways that young adults obtain cannabis, and how young adults with a medical cannabis card may be at greater risk for problems compared to young adults who use cannabis recreationally.

Predictors of Opioid Misuse During Emerging Adulthood: An Examination of Adolescent Individual, Family and Peer Factors

INTRODUCTION

Opioid misuse has reached epidemic proportions among emerging adults in the U.S. To inform prevention efforts, this study examined adolescent factors related to alcohol and marijuana (AM) use that are associated with a higher or lower risk for opioid misuse during emerging adulthood.

METHODS

We used 11 waves of survey data from a diverse California cohort (N = 6,509). Predictor variables from waves 1-7 (ages 11-17) included individual (resistance self-efficacy, positive expectancies) family (older sibling and important adult use), and peer (perceived norms, time spent with peers who use, peer approval) factors. Opioid misuse at wave 8 (mean age = 18.3) and wave 11 (mean age = 21.6) included heroin and nonmedical prescription drug use.

RESULTS

Initial latent growth models (LGMs) indicated that nearly all intercepts and slopes for individual, family, and peer AM factors predicted opioid misuse at waves 8 and 11. These associations were reduced to non-significance after adjusting for prior other substance use with the exception of three intercepts: positive expectancies, peer approval, and older sibling use predicted a higher probability of opioid misuse at wave 8.

CONCLUSIONS

Stronger AM positive expectancies, perceived peer approval of AM use, and older sibling AM use during adolescence are associated with a higher likelihood of opioid misuse during the transition to emerging adulthood. However, most adolescent factors were no longer associated with subsequent opioid misuse after adjusting for history of other substance use, highlighting the importance of considering the larger context of substance use in studies of opioid misuse among young people.

Primary Substance Use Prevention Programs for Children and Youth: A Systematic Review

CONTEXT

An updated synthesis of research on substance abuse prevention programs can promote enhanced uptake of programs with proven effectiveness, particularly when paired with information relevant to practitioners and policy makers.

OBJECTIVE

To assess the strength of the scientific evidence for psychoactive substance abuse prevention programs for school-aged children and youth.

DATA SOURCES

A systematic review was conducted of studies published up until March 31, 2020.

STUDY SELECTION

Articles on substance abuse prevention programs for school-aged children and youth were independently screened and included if they met eligibility criteria: (1) the program was designed for a general population of children and youth (ie, not designed for particular target groups), (2) the program was delivered to a general population, (3) the program only targeted children and youth, and (4) the study included a control group.

DATA EXTRACTION

Two reviewers independently evaluated study quality and extracted outcome data.

RESULTS

Ninety studies met eligibility criteria, representing 16 programs. Programs evaluated with the largest combined sample sizes were Drug Abuse Resistance Education, Project Adolescent Learning Experiences Resistance Training, Life Skills Training (LST), the Adolescent Alcohol Prevention Trial, and Project Choice.

LIMITATIONS

Given the heterogeneity of outcomes measured in the included studies, it was not possible to conduct a statistical meta-analysis of program effectiveness.

CONCLUSIONS

The most research has been conducted on the LST program. However, as with other programs included in this review, studies of LST effectiveness varied in quality. With this review, we provide an updated summary of evidence for primary prevention program effectiveness.

Developmental Trajectories of Tobacco/Nicotine and Cannabis Use and Patterns of Product Co-use in Young Adulthood

Introduction

Concurrent co-use of tobacco/nicotine and cannabis (T/C) products is common among young people and may increase risks for negative health and psychosocial outcomes, but little is known about developmental patterns of T/C co-use. This study aimed to identify distinct trajectory classes of concurrent T/C co-use from ages 16 to 21 and compare groups on T/C co-use behaviors in young adulthood.

Methods

Participants (n = 2497) reported T/C use on annual online surveys from 2015 to 2019 (ages 16-22). We used parallel process growth mixture models to model simultaneous trajectories of past-month cigarette, e-cigarette, smokeless tobacco, and cannabis use and identify latent classes of T/C trajectories. Classes were then compared on types and number of T/C products used and types of T/C co-use in young adulthood.

Results

Models revealed 4 T/C classes: Low/No T/C Use, Early Concurrent T/C Co-use, Late Concurrent T/C Co-use, and Tobacco Quitters/Cannabis Maintainers. Compared to other classes, the Early Concurrent T/C Co-use group-individuals with rapid progression to concurrent T/C co-use during adolescence-were more likely to report poly-tobacco use, poly-cannabis use, same-occasion sequential T/C co-use and T/C co-administration (ie, mixing T/C) of both combustible and vaping products in young adulthood.

Conclusion

Early progression to concurrent T/C co-use in adolescence is prospectively linked to poly-product use and co-use of T/C products in young adulthood. Prevention efforts targeting co-use of T/C products in adolescence may help to reduce riskier patterns of T/C use and co-use in young adulthood.

Study protocol for a group-based motivational interviewing brief intervention to reduce substance use and sexual risk behavior among young adults experiencing homelessness

BACKGROUND

Young people experiencing homelessness have alarmingly high rates of alcohol and other drug (AOD) use, which is associated with sexual risk behaviors such as unprotected sex, trading sex, and sex with multiple casual partners. Few risk reduction programs for this population have been developed and rigorously evaluated, particularly those that address both of these interrelated behaviors, use a collaborative and non-judgmental approach, and are feasible to deliver in settings where homeless young people seek services. This paper describes the protocol of a study evaluating a four-session Motivational Interviewing (MI)-based group risk reduction intervention for this population. The protocol has been shown to be efficacious in pilot work over 3 months with 200 homeless young adults [1]. The current study seeks to refine the intervention protocol and evaluate the program on a larger scale.

METHODS/DESIGN

In a cluster-cross-over randomized controlled trial, 18-25 year olds will receive the AWARE risk reduction program (n = 200) or standard care (n = 200) at one of three drop-in centers serving homeless youth in the Los Angeles area. We will evaluate intervention effects on primary outcomes of AOD use and sexual risk behavior, as well as secondary outcomes of health-related quality of life and social stability, over a 12-month period.

DISCUSSION

This project has the potential to fill a significant gap in prevention services by demonstrating that a brief intervention, feasible to deliver within settings where young people experiencing homelessness typically seeks services, can significantly reduce the interrelated problems of AOD use and sexual risk behavior.

Influence of an Implementation Support Intervention on Barriers and Facilitators to Delivery of a Substance Use Prevention Program

Implementation support interventions have helped organizations implement programs with quality and obtain intended outcomes. For example, a recent randomized controlled trial called Preparing to Run Effective Programs (PREP) showed that an implementation support intervention called Getting To Outcomes (GTO) improved implementation of an evidence-based substance use prevention program (CHOICE) run in community-based settings. However, more information is needed on how these interventions affect organizational barriers and facilitators of implementation. This paper aims to identify differences in implementation facilitators and barriers in sites conducting a substance use prevention program with and without GTO. PREP is a cluster-randomized controlled trial testing GTO, a two-year implementation support intervention, in Boys & Girls Clubs. The trial compares 15 Boys & Girls Club sites implementing CHOICE (control group), a five-session evidence-based alcohol and drug prevention program, with 14 Boys & Girls Club sites implementing CHOICE supported by GTO (intervention group). All sites received CHOICE training. Intervention sites also received GTO manuals, training, and onsite technical assistance to help practitioners complete implementation best practices specified by GTO (i.e., GTO steps). During the first year, technical assistance providers helped the intervention group adopt, plan, and deliver CHOICE, and then evaluate and make quality improvements to CHOICE implementation using feedback reports summarizing their data. Following the second year of CHOICE and GTO implementation, all sites participated in semi-structured interviews to identify barriers and facilitators to CHOICE implementation using the Consolidated Framework for Implementation Research (CFIR). This paper assesses the extent to which these facilitators and barriers differed between intervention and control group. Intervention sites had significantly higher average ratings than control sites for two constructs from the CFIR process domain: planning and reflecting and evaluating. At the same time, intervention sites had significantly lower ratings on the culture and available resources constructs. Findings suggest that strong planning, evaluation, and reflection-likely improved with GTO support-can facilitate implementation even in the face of perceptions of a less desirable implementation climate. These findings highlight that implementation support, such as GTO, is likely to help low-resourced community-based organizations improve program delivery through a focus on implementation processes.

Disentangling Within- and Between-Person Effects of Shared Risk Factors on E-cigarette and Cigarette Use Trajectories From Late Adolescence to Young Adulthood

BACKGROUND

Longitudinal studies report associations between use of electronic cigarettes (ECs) and cigarettes over time among young people, but do not distinguish within- from between-person effects, which complicates interpretation of findings. Further, the role of shared risk factors, such as substance use and mental health, in explaining longitudinal associations between EC and cigarette use remains unclear. This study used within- and between-person analyses to assess longitudinal associations between youths' EC and cigarette use and shared risk factors.

METHODS

Between 2015 and 2017, 2039 youths completed three Web-based surveys, allowing us to model EC and cigarette use from ages 16 to 20. Auto-regressive latent growth models with structured residuals (ALT-SR) examined both between-person and within-person associations between past-month frequency of EC use, cigarette use, and third variables (alcohol and marijuana use, mental health symptoms) over time.

RESULTS

Models revealed robust reciprocal associations between EC and cigarette use, such that more frequent EC use at one time predicted more frequent cigarette use at the subsequent time, and vice versa. Between-person analyses showed associations between shared risk factors and both EC and cigarette use. However, shared risk factors did not predict frequency of subsequent EC and cigarette use in within-person analyses.

CONCLUSIONS

Findings add to a growing body of research suggesting that EC use among youth is prospectively associated with progression toward greater cigarette use. Shared risk factors may help explain differences in EC and cigarette use patterns between young people, but do not appear to influence longitudinal trajectories of EC and cigarette use within individuals.

IMPLICATIONS

This study examined within- and between-person associations between e-cigarette use, cigarette use, and shared risk factors (alcohol use, marijuana use, mental health symptoms) in a longitudinal cohort of youths. Within- and between-person analyses revealed reciprocal prospective associations between e-cigarette and cigarette use, suggesting a progression toward more frequent use of both products over time. The shared risk factors examined here did not affect escalations in e-cigarette or cigarette use over time within individuals, but likely influence which youths use these products. Findings add to a growing body of evidence suggesting that e-cigarette use increases subsequent cigarette use in young people.

Sustaining an Evidence-Based Program Over Time: Moderators of Sustainability and the Role of the Getting to Outcomes® Implementation Support Intervention

Problematic rates of alcohol, e-cigarette, and other drug use among US adolescents highlight the need for effective implementation of evidence-based programs (EBPs), yet schools and community organizations have great difficulty implementing and sustaining EBPs. Although a growing number of studies show that implementation support interventions can improve EBP implementation, the literature on how to improve sustainability through implementation support is limited. This randomized controlled trial advances the literature by testing the effects of one such implementation intervention-Getting To Outcomes (GTO)-on sustainability of CHOICE, an after-school EBP for preventing substance use among middle-school students. CHOICE implementation was tracked for 2 years after GTO support ended across 29 Boys and Girls Club sites in the greater Los Angeles area. Predictors of sustainability were identified for a set of key tasks targeted by the GTO approach (e.g., goal setting, evaluation, collectively called "GTO performance") and for CHOICE fidelity using a series of path models. One year after GTO support ended, we found no differences between GTO and control sites on CHOICE fidelity. GTO performance was also similar between groups; however, GTO sites were superior in conducting evaluation. Better GTO performance predicted better CHOICE fidelity. Two years after GTO support ended, GTO sites were significantly more likely to sustain CHOICE implementation when compared with control sites. This study suggests that using an implementation support intervention like GTO can help low-resource settings continue to sustain their EBP implementation to help them get the most out of their investment.
