Risk and Promotive Factors Related to Cannabis Use Among American Indian Adolescents.

Reservation-dwelling American Indian adolescents are at exceedingly high risk for cannabis use. Prevention initiatives to delay the onset and escalation of use are needed. The risk and promotive factors approach to substance use prevention is a well-established framework for identifying the timing and targets for prevention initiatives. This study aimed to develop predictive models for the usage of cannabis using 22 salient risk and promotive factors. Models were developed using data from a cross-sectional study and further validated using data from a separate longitudinal study with three measurement occasions (baseline, 6-month follow-up, 1-year follow-up). Application of the model to longitudinal data showed an acceptable performance contemporaneously but waning prospective predictive utility over time. Despite the model's high specificity, the sensitivity was low, indicating an effective prediction of non-users but poor performance in correctly identifying users, particularly at the 1-year follow-up. This divergence can have significant implications. For example, a model that misclassifies future adolescent cannabis use could fail to provide necessary intervention for those at risk, leading to negative health and social consequences. Moreover, supplementary analysis points to the importance of considering change in risk and promotive factors over time.

Progression of Comorbid Depression and Substance Use among Racially Diverse Adults.

Comorbidity of depression and substance abuse is common and a major public health burden. Studies of this form of comorbidity in racial and ethnic minoritized (REM) populations are minimal and have mixed findings. The present study examined the effect of general risk factors (family bonding, supervision, involvement, peer delinquency), depression risk factors (caregiver depression), and substance use risk factors (adult family members, sibling, and peer substance use) in early adolescence (~ ages 13-14) on comorbid depression and substance use in later adolescence (~ ages 15-17) and adulthood (~ ages 29-31) and continuity in comorbidity from adolescence to adulthood. Longitudinal data on 1000 Black (n = 680) Hispanic (n = 170) and White (n = 150) individuals came from the Rochester Youth Development Study. Participants were interviewed 14 times over 17 years beginning in 1988. General risk factors predicted comorbidity across racial/ethnic groups. Substance specific risk predicted comorbidity among Black and Hispanic individuals whereas depression specific risk was predictive among White individuals. Adolescent comorbidity predicted comorbidity in adulthood across race. These findings highlight the importance of substance use intervention for racial and ethnic minoritized individuals and mental health risk factors in Whites. The continuity of comorbidity from adolescence to adulthood highlights the importance of targeting adolescents for intervention to prevent long-term manifestation of this form of comorbidity and its associated consequences.

#4Corners4Health Social Media Cancer Prevention Campaign for Emerging Adults: Protocol for a Randomized Stepped-Wedge Trial.

BACKGROUND: Many emerging adults (EAs) are prone to making unhealthy choices, which increase their risk of premature cancer morbidity and mortality. In the era of social media, rigorous research on interventions to promote health behaviors for cancer risk reduction among EAs delivered over social media is limited. Cancer prevention information and recommendations may reach EAs more effectively over social media than in settings such as health care, schools, and workplaces, particularly for EAs residing in rural areas. OBJECTIVE: This pragmatic randomized trial aims to evaluate a multirisk factor intervention using a social media campaign designed with community advisers aimed at decreasing cancer risk factors among EAs. The trial will target EAs from diverse backgrounds living in rural counties in the Four Corners states of Arizona, Colorado, New Mexico, and Utah. METHODS: We will recruit a sample of EAs (n=1000) aged 18 to 26 years residing in rural counties (Rural-Urban Continuum Codes 4 to 9) in the Four Corners states from the Qualtrics' research panel and enroll them in a randomized stepped-wedge, quasi-experimental design. The inclusion criteria include English proficiency and regular social media engagement. A social media intervention will promote guideline-related goals for increased physical activity, healthy eating, and human papillomavirus vaccination and reduced nicotine product use, alcohol intake, and solar UV radiation exposure. Campaign posts will cover digital and media literacy skills, responses to misinformation, communication with family and friends, and referral to community resources. The intervention will be delivered over 12 months in Facebook private groups and will be guided by advisory groups of community stakeholders and EAs and focus groups with EAs. The EAs will complete assessments at baseline and at 12, 26, 39, 52, and 104 weeks after randomization. Assessments will measure 6 cancer risk behaviors, theoretical mediators, and participants' engagement with the social media campaign. RESULTS: The trial is in its start-up phase. It is being led by a steering committee. Team members are working in 3 subcommittees to optimize community engagement, the social media intervention, and the measures to be used. The Stakeholder Organization Advisory Board and Emerging Adult Advisory Board were formed and provided initial input on the priority of cancer risk factors to target, social media use by EAs, and community resources available. A framework for the social media campaign with topics, format, and theoretical mediators has been created, along with protocols for campaign management. CONCLUSIONS: Social media can be used as a platform to counter misinformation and improve reliable health information to promote health behaviors that reduce cancer risks among EAs. Because of the popularity of web-based information sources among EAs, an innovative, multirisk factor intervention using a social media campaign has the potential to reduce their cancer risk behaviors.

Youth Exposure to Recreational Cannabis Legalization: Moderation of Effects by Sex and Parental Cannabis Use during Adolescence.

OBJECTIVE: Few studies of recreational cannabis legalization (RCL) have assessed adolescents both before and after RCL or considered moderators of RCL effects. The present study tested whether RCL was more strongly associated with cannabis use for girls and among youth whose parents had a history of cannabis use during adolescence. METHOD: Data were pooled from 940 adolescents from three intergenerational studies that began in Washington (where RCL was enacted in 2012), Oregon (RCL year = 2015), and New York (RCL year = 2021). Youth were assessed repeatedly from ages 13 to 18 years (k = 3,650 person-years) from 1999 to 2020 (prior to RCL in New York). Parent cannabis use at or before age 18 years (yes/no) was assessed prospectively during the parent's adolescence. Multilevel models focused on the between-subjects effects of years of youth exposure to RCL on adolescents' mean cannabis use likelihood, and interactions with child sex and parent use history. RESULTS: Child exposure to RCL was associated with a higher likelihood of cannabis use if their parents had a history of adolescent use, (Estimate [SE] = 0.67 [0.25], p = 0.008), versus no such history (Estimate [SE] = -0.05 [0.28], p = 0.855). RCL effects were not moderated by child sex. CONCLUSIONS: The effects of RCL on adolescents' cannabis use may depend on their parents' history of using the drug. Identifying other moderators of RCL effects, and understanding the mechanisms of these risks and the ways that parents and communities can offset them, are prevention priorities.

(1) Adolescents' use of cannabis may have intergenerational consequences, making it more likely their future offspring will use cannabis. (2) Whether or not recreational cannabis legalization influences adolescents' cannabis use may depend on their parents' cannabis use history. (3) Parenting in a state with liberalized cannabis policies may present new challenges and require that novel prevention resources be developed.

Can High and Consistent School-Related Protective Factors Prevent Cannabis Use Among American Indian Middle School Students?

BACKGROUND: High cannabis use rates among American Indian (AI) adolescents necessitate the identification of factors that protect against early cannabis initiation. METHODS: Data collected from 279 AI middle school students attending reservation-based schools in 2018 and 2019 were analyzed. Three waves of data, with approximately 6 months between each, were used. A repeated measures latent class analysis examined a school-related protective factor index over three waves. The predictive power of lifetime cannabis use on school protection class membership was estimated, along with differences in past month cannabis use at follow-up 2 across school protection classes while holding baseline use constant. RESULTS: Four school protection classes were identified: high, moderate, low, and declining protection. Abstinence at baseline was associated with an increased odds of membership in the high protection class compared to the moderate and low protection classes. Students with consistent and high school protection throughout middle school were significantly less likely to report past month cannabis use at follow-up 2 compared to other classes. IMPLICATIONS FOR SCHOOL HEALTH POLICY, PRACTICE, AND EQUITY: Maintaining a high level of school protection throughout middle school substantially lowers the odds of cannabis use among AI adolescents. CONCLUSIONS: Interventions to promote school-related protective factors in this population are essential and should be designed and tested.

Nonmedical Prescription Drug Use Among Female Adolescents: The Relative Influence of Maternal Factors, Social Norms, and Perceptions of Risk and Availability.

Increasing understanding of the risk and protective factors for adolescent nonmedical use of prescription drugs (NMUPD) could inform prevention efforts. Several correlates have been identified, including parental factors, perceptions about use and accessibility, social norms, and age. However, these constructs have rarely been simultaneously examined using paired data from parents and adolescents. We aimed to examine the relative influence of these correlates among dyads (N=349) of mothers and adolescent daughters. Using multiple logistic regression, daughters' past NMUPD and inclination for future NMUPD were regressed onto descriptive norms for friend use, perceived drug accessibility and risk of harm from use, daughter age, mothers' disapproval about use, mothers' past NMUPD and inclination for future NMUPD, and the mother-daughter relationship quality. Akaike weights and lasso regressions were also estimated to evaluate the relative importance of each correlate. Higher descriptive norms for friend use, older age, and mothers' inclination for NMUPD were risk factors for daughters' NMUPD, while a closer mother-daughter relationship and mothers' disapproving attitudes towards NMUPD were protective factors. The three analysis approaches were corroborative. Results suggest friend descriptive norms, mother-daughter relationship quality, and mothers' attitudes about NMUPD are important prevention targets.

Personality and emotion dysregulation profiles predict differential engagement in a wide range of health-risk behaviors.

OBJECTIVE: Health-risk behaviors have an unclear etiology and college students have elevated risk for engagement. Emotion dysregulation and several personality dimensions have been implicated in health-risk behaviors, but these constructs have rarely been studied together. Further, it is unknown if different types of health-risk behaviors have distinct etiologies. PARTICIPANTS: 2077 college students completed a cross-sectional survey. METHODS: Latent profile analysis discerned classes of participants from emotion dysregulation and personality dimensions. Differential engagement in self-injury, suicidality, disordered eating, substance misuse, and unprotected sex was evaluated across classes. RESULTS: Three classes were identified, which were primarily distinguished by emotion dysregulation, urgency, and neuroticism. Health-risk behaviors generally increased across classes with increasing emotion-related constructs. Self-injury and suicidality demonstrated different patterns than other health-risk behaviors. CONCLUSIONS: Results elucidate heterogeneity in health-risk behavior engagement. Focusing on emotional difficulties may be more important for reducing self-injury and suicidality than disordered eating, substance misuse, and risky sex.

Health and Safety Regulations for COVID-19: A Policy Analysis.

The COVID-19 pandemic spurred some regulators in the USA to require occupational health and safety programs to prevent COVID-19 transmission in workplaces. The objective of this study was to describe such state and federal regulations enacted between January 2020 and January 2022. Regulations, including emergency temporary standards (ETS) and permanent standards, were identified through a search of Nexis Uni and Bloomberg Law and review of US OSHA websites and the Federal Register. Full texts were reviewed for regulatory scope, hazard and exposure definitions, determination of exposure or risk levels, and control strategies. Four state (California, Michigan, Virginia, and Oregon) and two federal regulations were identified. All regulations described respiratory aerosols as the primary source of SARS-CoV-2 and recognized person-to-person transmission by droplet, airborne, and contact routes. Only the US OSHA ETS for healthcare explicitly stated that inhalation of respiratory particles was the most likely method of COVID-19 transmission. The Virginia, Michigan, and Oregon regulations described different categories of risk defined by exposure frequency and duration or specific workplace activities. California described exposure as places and times when employees come into contact or congregate with other people. The US OSHA ETS for healthcare described exposure as involving close contact with suspected or confirmed COVID-19 patients. While all of the state regulations required strategies from across the hierarchy, only the Virginia regulations specifically incorporated the hierarchy of controls. Only the California and Virginia regulations explicitly linked control strategies to the transmission route, while Virginia demarcated control strategies by risk level. Oregon linked risk level to occupancy levels and physical distancing requirements and referred to the use of a layered approach for transmission control. The US OSHA ETS for healthcare defined droplet and airborne precautions but made no mention of the hierarchy of controls or risk levels. Respirators were discussed in most of the regulations. The first Michigan regulation explicitly required respirators appropriate to exposure risk. The California regulations noted that respirators protect the wearer while face coverings protect people around the wearer. These regulations offer insights for a permanent US OSHA infectious disease regulation, such as the need to consider a range of transmission modes including near- and far-range aerosol inhalation, endemic and novel pathogens, workplaces beyond healthcare settings, factors that contribute to exposure and risk, the hierarchy of controls, the role of vaccination, and the importance of written exposure assessment and infection prevention plans.

The Process of Responding to COVID-19 Misinformation in a Social Media Feed.

Misinformation can undermine public health recommendations. Our team evaluated a 9-week social media campaign promoting COVID-19 prevention to mothers (n = 303) of teen daughters in January-March 2021. We implemented an epidemiological model for monitoring, diagnosing, and responding quickly to misinformation from mothers. Overall, 54 comments out of 1617 total comments (3.3%) from 20 mothers (6.6% of sample) contained misinformation. Misinformation was presented in direct statements and indirectly as hypothetical questions, source derogation, and personal stories, and attributed to others. Misinformation occurred most (n = 40; 74%) in comments on vaccination posts. The community manager responded to 48 (89%) misinformation comments by acknowledging the comment and rebutting misinformation. No mothers who provided misinformation left the Facebook groups and a few commented again (n = 10) or reacted (n = 3) to responses. Only a small number of comments conveyed misinformation. Our quick-response epidemiological protocol appeared to prevent debate and dropout and exposed these mothers to credible information.

Effects of Cannabis Legalization on Adolescent Cannabis Use Across 3 Studies.

INTRODUCTION: Canada, Uruguay, and 18 states in the U.S. have legalized the use of nonmedical (recreational) cannabis for adults, yet the impact of legalization on adolescent cannabis use remains unclear. This study examined whether cannabis legalization for adults predicted changes in the probability of cannabis use among adolescents aged 13-18 years. METHODS: Data were drawn from 3 longitudinal studies of youth (spanning 1999-2020) centered in 3 U.S. states: Oregon, New York, and Washington. During this time, Oregon (2015) and Washington (2012) passed cannabis legalization; New York did not. In each study, youth average age was 15 years (total N=940; 49%-56% female, 11%-81% Black/African American and/or Latinx). Multilevel modeling (in 2021) of repeated measures tested whether legalization predicted within- or between-person change in past-year cannabis use or use frequency over time. RESULTS: Change in legalization status across adolescence was not significantly related to within-person change in the probability or frequency of self-reported past-year cannabis use. At the between-person level, youth who spent more of their adolescence under legalization were no more or less likely to have used cannabis at age 15 years than adolescents who spent little or no time under legalization. CONCLUSIONS: This study addresses several limitations of repeated cross-sectional studies of the impact of cannabis legalization on adolescent cannabis use. Findings are not consistent with changes in the prevalence or frequency of adolescent cannabis use after legalization. Ongoing surveillance and analyses of subpopulations are recommended.

Heavy episodic drinking in adolescence and alcohol-related problems in adulthood: A developmental approach to alcohol use across the life course.

Heavy episodic drinking (HED) is a major public health concern, and youth who engage in HED are at increased risk for alcohol-related problems that continue into adulthood. Importantly, there is heterogeneity in the onset and course of adolescent HED, as youth exhibit different trajectories of initiation and progression into heavy drinking. Much of what is known about the etiology of adolescent HED and alcohol-related problems that persist into adulthood comes from studies of predominantly White, middle-class youth. Because alcohol use and related problems vary by race/ethnicity and socioeconomic status, it is unclear whether previous findings are relevant for understanding developmental antecedents and distal consequences of adolescent HED for minoritized individuals. In the current study, we utilize a developmental psychopathology perspective to fill this gap in the literature. Using a racially and economically diverse cohort followed from adolescence well into adulthood, we apply group-based trajectory modeling (GBTM) to identify patterns of involvement in HED from age 14 to 17 years. We then investigate developmental antecedents of GBTM class membership, and alcohol-related distal outcomes in adulthood (∼ age 31 years) associated with GBTM class membership. Results highlight the importance of adolescent alcohol use in predicting future alcohol use in adulthood.

Two-Part Models for Father-Child Relationship Variables: Presence in the Child's Life and Quality of the Relationship Conditional on Some Presence.

Parent-child relationship variables are often measured using a two-part approach. For example, when assessing the warmth of the father-child relationship, a child is first asked if they have contact with their father; if so, the level of warmth they feel toward him is ascertained. In this setting, data on the warmth measure is missing for children without contact with their father, and such missing data can pose a significant methodological and substantive challenge when the variable is used as an outcome or antecedent variable in a model. In both cases, it is advantageous to use an analytic method that simultaneously models whether the child has contact with the father, and if they do, the degree to which the father-child relationship is characterized by warmth. This is particularly relevant when the two-part variable is measured over time, as contact status may change. We offer a pragmatic tutorial for using two-part variables in regression models, including a brief overview of growth modeling, an explanation of the techniques to handle two-part variables as predictors and outcomes in the context of growth modeling, examples with real data, and syntax in both R and Mplus for fitting all discussed models.

Promoting Social Distancing and COVID-19 Vaccine Intentions to Mothers: Randomized Comparison of Information Sources in Social Media Messages.

Background: Social media disseminated information and spread misinformation during the COVID-19 pandemic that affected prevention measures, including social distancing and vaccine acceptance. Objective: In this study, we aimed to test the effect of a series of social media posts promoting COVID-19 nonpharmaceutical interventions (NPIs) and vaccine intentions and compare effects among 3 common types of information sources: government agency, near-peer parents, and news media. Methods: A sample of mothers of teen daughters (N=303) recruited from a prior trial were enrolled in a 3 (information source) × 4 (assessment period) randomized factorial trial from January to March 2021 to evaluate the effects of information sources in a social media campaign addressing NPIs (ie, social distancing), COVID-19 vaccinations, media literacy, and mother-daughter communication about COVID-19. Mothers received 1 social media post per day in 3 randomly assigned Facebook private groups, Monday-Friday, covering all 4 topics each week, plus 1 additional post on a positive nonpandemic topic to promote engagement. Posts in the 3 groups had the same messages but differed by links to information from government agencies, near-peer parents, or news media in the post. Mothers reported on social distancing behavior and COVID-19 vaccine intentions for self and daughter, theoretic mediators, and covariates in baseline and 3-, 6-, and 9-week postrandomization assessments. Views, reactions, and comments related to each post were counted to measure engagement with the messages. Results: Nearly all mothers (n=298, 98.3%) remained in the Facebook private groups throughout the 9-week trial period, and follow-up rates were high (n=276, 91.1%, completed the 3-week posttest; n=273, 90.1%, completed the 6-week posttest; n=275, 90.8%, completed the 9-week posttest; and n=244, 80.5%, completed all assessments). In intent-to-treat analyses, social distancing behavior by mothers (b=-0.10, 95% CI -0.12 to -0.08, P<.001) and daughters (b=-0.10, 95% CI -0.18 to -0.03, P<.001) decreased over time but vaccine intentions increased (mothers: b=0.34, 95% CI 0.19-0.49, P<.001; daughters: b=0.17, 95% CI 0.04-0.29, P=.01). Decrease in social distancing by daughters was greater in the near-peer source group (b=-0.04, 95% CI -0.07 to 0.00, P=.03) and lesser in the government agency group (b=0.05, 95% CI 0.02-0.09, P=.003). The higher perceived credibility of the assigned information source increased social distancing (mothers: b=0.29, 95% CI 0.09-0.49, P<.01; daughters: b=0.31, 95% CI 0.11-0.51, P<.01) and vaccine intentions (mothers: b=4.18, 95% CI 1.83-6.53, P<.001; daughters: b=3.36, 95% CI 1.67-5.04, P<.001). Mothers' intentions to vaccinate self may have increased when they considered the near-peer source to be not credible (b=-0.50, 95% CI -0.99 to -0.01, P=.05). Conclusions: Decreasing case counts, relaxation of government restrictions, and vaccine distribution during the study may explain the decreased social distancing and increased vaccine intentions. When promoting COVID-19 prevention, campaign planners may be more effective when selecting information sources that audiences consider credible, as no source was more credible in general.

Effects of Engagement with a Social Media Campaign for Mothers to Prevent Indoor Tanning by Teens in a Randomized Trial.

In a social media campaign aimed at reducing mothers' permissiveness for indoor tanning (IT) by their teenage daughters, a secondary analysis of campaign engagement effects on IT outcomes was performed. Mothers (n = 869) with daughters aged 14-17 were recruited in 34 states that did not ban IT by minors under age 18 for a randomized trial with follow-up at 12 months (end of intervention) and 18 months (6 months after intervention) post-randomization. Daughters' (n = 469) baseline and follow-up responses were analyzed too. Mothers received a Facebook feed on adolescent health topics that included posts about preventing IT (intervention) or prescription drug misuse (control). Engagement was measured by extracting reactions (e.g., like, sad, etc.) and comments posted by mothers to the campaign posts. Overall, 76.4% of posts received a reaction and/or comment. Mothers who engaged with IT posts were less permissive of daughters' IT immediately at the conclusion of the campaign (permit IT: -0.39, p < .05; facilitate IT: -0.29, p < .05) and 6 months after intervention (permit IT: -0.32, p < .05; facilitate IT: -0.31, p < .05) than mothers who did not engage with posts. Engagement with posts was essential to the success of a social media campaign for preventing IT by minors by reducing mothers' permissiveness.

Eye Contact in Video Communication: Experiences of Co-creating Relationships.

As a result of the COVID-19 pandemic, increased number of persons have been forced to limit their interactions with friends and families to contact via video, which excludes eye-contact. The aim of this study was to examine individuals' experiences of the difference between forced skewed visuality and the ability for eye-contact in conversations. Two custom-made units allowed 15 participants interacting in dyads to alternate between being able to make eye contact and having that ability removed through skewed visuality. Participants reported their experiences in semi-structured interviews. Data analyzed with qualitative content analysis resulted in three themes: Shared eye contact allows us to create our relationship together; With eye contact, we adjust to each other to feel more connected and less intimidated; and We get more self-conscious when the visuality is skewed or shifting. The results imply that skewed visuality as forced lack of eye-contact in video conversations effects embodied non-verbal processes related to sense of connectedness and participatory sensemaking, creating a sense of both emotional and physical distance, as well as heightening self-awareness about the need of actively regulating the other. We argue that this is one of the ways to understand the impact of moving interactions to online communication.

Follow-Up Analyses From a Wait-List Controlled Trial of Occupational Therapist-Delivered Cognitive-Behavioral Therapy for Insomnia Among Veterans With Chronic Insomnia.

IMPORTANCE: Veterans often experience chronic insomnia, and professionals capable of delivering effective interventions to address this problem are lacking. OBJECTIVE: To evaluate the efficacy of the Restoring Effective Sleep Tranquility (REST) program, an occupational therapist-led cognitive-behavioral therapy for insomnia (CBT-I) intervention to treat sleep problems among post- 9/11 veterans. DESIGN: Wait-list controlled trial with 3-mo follow-up. SETTING: Community-based veteran support program in a Mountain West university. PARTICIPANTS: Fifteen post-9/11 veterans with sleep disturbances who were assigned to either the REST intervention or a wait-list control group. Outcomes and Measures: Sleep-related, health-related, and participation-related patient-reported outcomes (PROs) and daily sleep diary variables. RESULTS: Wait-list controlled trial benefits included improved sleep-related (e.g., sleep disturbance), health-related (e.g., depression), and participation-related (e.g., meaningful activity) PROs. Findings were confirmed after participants in both the intervention and the control groups (n = 13) received the REST intervention, including improved daily sleep diary outcomes (e.g., sleep efficiency). All gains were maintained at 3 mo. CONCLUSIONS AND RELEVANCE: Occupational therapy practitioners with advanced training in CBT-I have the potential to safely deliver an effective CBT-I intervention to veterans with sleep disturbances in a community-based setting. What This Article Adds: Occupational therapy practitioners with sleep-related education and training can positively affect the well-being of their clients through improving sleep participation.

The Comparative Roles of Mentor Self-Efficacy and Empathy in Fostering Relationship Quality with Youth.

Youth mentors' efficacy beliefs and relational skills should both influence the quality of their connections with their mentees, but a lack of research based on large, dyadic and longitudinal samples limits understanding of how mentor characteristics impact relationship quality. This study used three staged and process-focused structural equation models to (1) investigate the mutually reinforcing effects of mentor self-efficacy and empathy over time; (2) compare the longitudinal effects of mid-program mentor efficacy and empathy on end of program mentor and mentee perceptions of relationship quality; and (3) test a similar comparative model using cross-sectional end of program assessments to account for developmental changes in these variables over time. The sample consisted of 664 college-age mentor (76.5% female; [Formula: see text] age = 24.5, range = 21-53; 23.5% non-White) and youth mentee (41% female; [Formula: see text] age = 14.1, range = 10-19; 41.9% non-White) dyads. Mentor empathy predicted mentor perceptions of relationship quality at both time points and mentee perceptions at the end of the program. Mentor efficacy only predicted mentor reported relationship quality at the end of the program. The findings emphasize the importance of investing in empathy training for mentors to support both partners' positive evaluation of the relationship. Program support to increase mentor self-efficacy should also have added value for mentors.

Adolescent Substance Use Prevention: Long-Term Benefits of School Engagement.

BACKGROUND: To determine if school engagement is a viable target for early prevention of adolescent substance use, this study investigated whether school engagement in early adolescence (ages 12-14) is a cause of alcohol and cannabis use during middle to late adolescence (ages 15-19). METHODS: To facilitate causal inference, inverse probability of treatment weights (IPTWs), which are based on estimated probabilities of treatment selection (ie, school engagement), were created based on a robust set of potential confounders. Using the IPTWs, a cumulative link mixed model was fit to examine the impact of school engagement on alcohol and cannabis use among an ethnically diverse sample of adolescents (N = 360). RESULTS: School engagement was associated with a lower level of alcohol and cannabis use from age 15 to 18. School engagement was not associated with change in alcohol and cannabis use over time, suggesting that school engagement emits its effect early in the developmental course of substance use and offers protection throughout adolescence. CONCLUSIONS: This study supports a compensatory role of early school engagement in substance use across middle and late adolescence. School engagement is a malleable factor and thus offers an avenue for prevention efforts.

Persisting Effects of a Social Media Campaign to Prevent Indoor Tanning: A Randomized Trial.

BACKGROUND: A social media campaign for mothers aimed at reducing indoor tanning (IT) by adolescent daughters reduced mothers' permissiveness toward IT in an immediate posttest. Whether the effects persisted at 6 months after the campaign remains to be determined. METHODS: Mothers (N = 869) of daughters ages 14-17 in 34 states without bans on IT by minors were enrolled in a randomized trial. All mothers received an adolescent health campaign over 12 months with posts on preventing IT (intervention) or prescription drug misuse (control). Mothers completed a follow-up at 18 months post-randomization measuring IT permissiveness, attitudes, intentions, communication, and behavior, and support for state bans. Daughters (n = 469; 54.0%) just completed baseline and follow-up surveys. RESULTS: Structural equation modeling showed that intervention-group mothers were less permissive of IT by daughters [unstandardized coefficient, -0.17; 95% confidence interval (CI), -0.31 to -0.03], had greater self-efficacy to refuse daughter's IT requests (0.17; 95% CI, 0.06-0.29) and lower IT intentions themselves (-0.18; 95% CI, -0.35 to -0.01), and were more supportive of bans on IT by minors (0.23; 95% CI, 0.02-0.43) than control-group mothers. Intervention-group daughters expressed less positive IT attitudes than controls (-0.16; 95% CI, 0.31 to -0.01). CONCLUSIONS: The social media campaign may have had a persisting effect of convincing mothers to withhold permission for daughters to indoor tan for 6 months after its conclusion. Reduced IT intentions and increased support for bans on IT by minors also persisted among mothers. IMPACT: Social media may increase support among mothers to place more restrictions on IT by minors.

School-related Promotive Factors Related to Cannabis Use Among American Indian Adolescents.

Reservation-dwelling American Indian adolescents are at exceedingly high risk for cannabis use. Prevention initiatives to delay onset and escalation of use are needed. School engagement and student's positive experiences at school have been identified as key promotive factors against cannabis use in the general population of adolescents, but little work has examined these factors among American Indian youth. Seven school-related promotive factors were examined as predictors of past 30-day cannabis use (measured 6 months later), controlling for previous onset of cannabis use as well as a set of relevant potential confounders. Models were tested using 280 adolescents in 6th or 7th grade at the start of the study from two reservation-based schools in the US. Students were surveyed three times, with 6 months in between each survey. The average age at the start of the study was 11.99 years (SD = 0.87) and 54% of participants were female. Using a cumulative logit model to predict past 30-day use, American Indian youth who reported greater school bonding, academic aspirations, proclivity to endeavor in their studies, and interest in school at Wave 2 reported less 30-day cannabis use at Wave 3 (controlling for onset of cannabis at Wave 1 and several other control variables). No evidence of an effect of self-reported grades, perceived safety, or participation in school-related extracurricular activities was found. Given substantial deterioration of these school-related promotive factors over time, and the effect of the school-related promotive factors on subsequent cannabis use, efforts to design and test interventions to promote school engagement as a protective measure against cannabis use is warranted.
