One such intervention, the Marijuana eCHECKUP TO GO (eCTG) program, has relatively few studies investigating mechanisms of change and related outcomes. This intervention provides users with personalized normative feedback to adjust user’s normative perceptions and use patterns. The current study tested moderated mediation of program effects between the eCTG intervention condition and a healthy stress management (HSM) control condition in a college student sample of near-daily cannabis users. Protective behavioral strategies (PBS) were measured among the eCTG condition Methods: Data were analyzed from a sample of 227 students who were randomly assigned to the eCTG intervention condition or HSM control condition. Change in cannabis use frequency was measured by re-administering the baseline survey at a six-week follow-up. Multi-group moderated mediation path analysis tested the effects of the eCTG intervention on change in cannabis use frequency through PBS, descriptive norms, and injunctive norms, with multi-group categories defined by sex. Results: Direct effects indicated the intervention predicted reduced descriptive norm perceptions and cannabis use frequency. An indirect effect was found for the intervention condition on reducing cannabis use frequency through change in descriptive norms in males. Similarly, an indirect effect was seen for intervention condition on reducing cannabis use frequency through change in injunctive norms for females. Conclusions: Findings suggest changes in descriptive norms played a sex-specific mediating role in the mechanisms of change for the eCTG intervention on reductions in cannabis use frequency.

This study randomly assigned college students who reported frequent marijuana use (i.e., approximately five times per week) in fall 2016 to receive Marijuana e-CHECKUP TO GO or healthy stress management (HSM) strategies. The final baseline sample included 298 participants. Path analyses tested direct program effects on marijuana use at six-week posttest, as well as the indirect effect via use within four activities frequently participated in by college students: socializing, being physically active, studying, and being in class. Direct Marijuana e-CHECKUP TO GO effects on reductions in frequent use were transmitted by decreased marijuana use while studying and no use while socializing, being physically active, or in class. Marijuana e-CHECKUP TO GO may be most effective at reducing use of marijuana among college students while studying.

Children with a substance-using parent in the home are compared to those without a substance-using parent in the home. Methods: Longitudinal data from waves 1 and 3 of the second National Study of Child and Adolescent Well-Being (NSCAW II) are used. NSCAW II is a national sample of families with children and youth aged birth to 17.5 investigated by child protective services (CPS). A subset of the data (analyzed with domain analysis methods) is used for this study (n = 575). Eight well-being outcomes from four domains (cognitive development, physical health, psychological/behavioral development and social/emotional competence) are analyzed. Findings: We hypothesized that (among children investigated for maltreatment and not removed from home) children whose parents used substances would exhibit lower mean levels of well-being at thirty-six months follow-up compared to those whose parents did not use. Unexpectedly, we found no significant differences in well-being levels between children with parents in the home using substances and those without. Conclusions: Children with substance-using parents may be able to remain at home over an extended period after investigation, while maintaining well-being levels similar to children at home with parents not using substances. If an effective safety plan can be put in place, this option may provide a path to maintaining safety, permanency and well-being for such children without placement in out-of-home care.

Identifying risk factors for marijuana user status will improve understanding of different populations of users, which may inform prediction of individuals most likely to experience negative outcomes. Objectives: To identify predictors of marijuana use initiation in young adults. We simultaneously examined a broad range of potential predictors and all their possible interactions, including constructs that have not been previously studied in substance use initiation research. Methods: Data were repeated cross-sectional survey responses from college students in Colorado (N ¼ 4052, 77% White, 61% female, mean age ¼ 22.77). Measures came from the National College Health Assessment, which assesses numerous health and behavioral constructs. We used recursive partitioning and random forest models to identify predictors of ever having used marijuana out of 206 variables. Results: Classification trees identified engagement in increased alcohol use and sexual behavior as salient correlates of marijuana use initiation. Parsimonious recursive partitioning trees explained a substantial amount of variability in marijuana user status (39% in the full model and 24% when alcohol variables were excluded). Random forest models predicted user status with 74.11% and 66.91% accuracy in the full model and when alcohol variables were excluded, respectively. Conclusions: Results support the use of exploratory analyses to explain heterogeneity among marijuana users and non-users. Since engagement in other health-risk behaviors were salient predictors of use initiation, prevention efforts to reduce harm from marijuana use may benefit from targeting risk factors for health-risk behaviors in general.

Understanding the impact of these policy changes on marijuana use and perceptions of acceptability and safety of use is needed. The current study examined perceptions and patterns of marijuana use among college students, a population at increased risk for initiation and heavy use. Method: Data include Colorado university students and national sample averages. We used repeated cross-sectional analyses to examine responses to the American College Health Association National College Health Assessment and added marijuana measures. We examined differences in use and norms pre-to post-legalization among Colorado college students. Colorado data were also compared to national summary statistics. Results: Social norms, use initiation, and use recency and frequency in Colorado increased significantly across changes in recreational legislation. Descriptive norms and rates of ever users in Colorado increased faster than national averages. Conclusions: Results suggest recreational legalization increases how quickly social norms become more approving. As marijuana policy continues to change, implementing social norms interventions alongside legislative changes may offset increases in risk for use initiation and frequency by countering increased social norms favorable to use.

While numerous constructs have been implicated as risk factors, researchers have not significantly improved at predicting SITBs, possibly due to constraints of confirmatory analyses. Classification trees are exploratory, person-centered analyses that enable joint examination of numerous correlates and their interactions. Thus, classification trees may discern previously unstudied risk factors and identify distinct subpopulations with elevated risk for SITBs. We tested classification trees that evaluated 298 potential correlates of non-suicidal self-injury and suicidal ideation across self-identified females and males. Data came from 5,131 college students who completed the National College Health Assessment, which assesses a wide-range of health-related constructs. Models produced parsimonious decision trees that accounted for a substantial amount of outcome variability (38.3-51.5%). Psychopathology, poorer psychological well-being, and other SITBs emerged as important correlates for all participants. Trauma, disordered eating, and heavy alcohol use were salient among females, whereas alcohol use norms were important correlates among males. Importantly, models identified several constructs that may be amenable to intervention. Results support the use of exploratory analyses to explicate heterogeneity among individuals who engage in SITBs and suggest that gender identity is an important moderator for certain risk factors.

Of 292 consecutively enrolled exclusive marijuana-only users visiting the ED for any reason, 37% (n = 107) reported using marijuana on the advice of a medical doctor, and 63% (n = 185) reported that they did not use it under the advice of a medical doctor (ie, non-medical user). Participants denied using any other drug with the exception of alcohol. Participants completed the Addiction Severity Index-Lite which provided composite and individual items related to drug use problems, psychiatric problems, medical problems, and alcohol use problems. Self-efficacy for avoiding drug use and sociodemographic characteristics were also collected. In a multivariate model, compared to non-medical marijuana users, medical users reported a high...

Liberalization of marijuana use policies is hypothesized to decrease social norms discouraging use, which protects against marijuana use. This may increase the importance of protective behavioral strategies (PBS) to reduce marijuana use harm. This study tested direct and moderated (by sex) program effects of an adapted version of the Marijuana eCHECKUPTO GO, a web-based marijuana use intervention providing university-specific personalized feedback (PF) with normative information and PBS to students attending a university in a state with legalized adult recreational marijuana. Participants were 298 heavy-using college students randomly assigned to receive Marijuana eCHECKUPTO GO or strategies for healthy stress management (HSM). General linear models (GLMs) tested direct program effects on proximal intervention targets, marijuana use, and use consequences. Multi-group GLMs then tested the moderating effect of sex on direct interven...

Data included county-level 2015 maltreatment reports from the National Child Abuse and Neglect Data System, modeled drug-overdose mortality from the Centers for Disease Control, United States Department of Agriculture Rural-Urban Continuum Codes, US Census demographic data and crime reports from the Federal Bureau of Investigation. All data were linked across counties. Zero-inflated negative binomial (ZINB) regression was used for county-level analysis. As hypothesized, results from the ZINB model showed a significant and positive relationship between drug overdose mortality and child maltreatment report rates (χ = 101.26, p < .0001). This relationship was moderated by position on the rura...

Although adverse childhood experiences (ACEs) have been associated with poorer behavioral outcomes among youth, less is known about the possible protective factors that may influence the relationship between early adversity and risk-taking behavior. This study examined whether protective adult relationships moderated the link between cumulative ACEs and substance use and delinquency after controlling for demographic characteristics in child welfare-involved youth. The sample included 1054 youth, ages 11-17, from the National Survey of Child and Adolescent Well-Being II who were in the first wave of data collection. Results showed that protective adult relationships moderated the relationship between ACEs and substance use, but not for delinquency. Specifically, under lower levels of protective adult relationships, cumulative ACEs related to increased substance use among youth. Implications for child welfare practices to target youths&amp;amp;amp;amp;amp;amp;#39; support systems are discussed.

Although most college students initiate smoking before the age of 18, recent evidence suggests a sizable minority of undergraduates report starting smoking while in college. This study examined the relationship between past year alcohol use and past year smoking initiation among a sample of undergraduate students (ages 18-24) attending a large public university in the Southwestern United States. A total of 3,450 students (67% female, 45% non-white) participated in four cross-sectional waves of an internet survey measuring alcohol, tobacco, and other drug use. Approximately 20% of the sample reported smoking during the past month and 17% of ever-smokers reported initiating smoking at the age of 19 or older. Overall, ever-smoking participants reported a significantly lower age of first drink (M = 15.4, SD = 2.2) than age of first cigarette (M = 16.4, SD = 2.6), t(1398) = -13.62, ...
