Protective Behavioral Strategies Mediate the Relation Between Sensation Seeking and Marijuana-Related Consequences.

BACKGROUND: Greater levels of sensation seeking are associated with experiencing more marijuana-related consequences (MRC). Protective behavioral strategies (PBS) use is associated with both the lower frequency of marijuana use and fewer marijuana-related consequences. However, research has not examined whether PBS use mediates the relation between sensation seeking and MRC. METHODS: The current study is a secondary data analysis of the initial Marijuana Outcomes Study Team data collection. A path analysis was conducted to assess for indirect effects from both risk and experience seeking (facets of sensation seeking) to MRC via frequency of PBS use, controlling for marijuana use frequency. RESULTS: We found negative relations between both experience seeking and PBS and MRC, and a positive relation between risk seeking and MRC. Furthermore, PBS mediated the relation between both risk and experience seeking and MRC. CONCLUSIONS: Results suggest that PBS is a mediator of the sensation seeking-MRC relationship. Discussions about selecting and implementing PBS use may be particularly useful for treatment of clients high in risk seeking.

A Burning Problem: Cannabis Lessons Learned from Colorado.

With recent increases in cannabis' popularity, including being legalized in several states, new issues have emerged related to use. Increases in the number of users, new products, and home growing all present distinct concerns. In the present review, we explored various cannabis-related concerns (i.e. use, acquiring, growing, and public health/policy) that have arisen in Colorado in order to provide information on emerging issues and future directions to mitigate negative outcomes that could occur in states considering, or that already have implemented, a legalized cannabis market. Specific to Colorado, issues have arisen related to edibles, vaporizers/'e-cannabis', concentrates, growing, quantifying use, intoxicated driving, and arrests. Understanding cannabis dosing (including dose-dependent effects and related consequences), standardizing quantities, evaluating the safety of new products, and developing harm reduction interventions are important next steps for informing public policy and promoting health and well-being. Overall, increasing our knowledge of emerging issues related to cannabis is key to promoting the benefits and combating the potential harms of cannabis, especially for states legalizing medical or recreational cannabis.

Development and Validation of the Positive Outcomes of Cannabis Use Scale (POCUS) Among Predominantly White Adults in the United States.

Operant conditioning and social learning theories suggest that positive cannabis use-related outcomes are a primary contributor to maintained use and risk for dependence. However, currently there does not exist a reliable, validated measure of positive cannabis-related outcomes. This study sought to develop and psychometrically evaluate the Positive Outcomes of Cannabis Use Scale (POCUS). We collected three samples, college students (N = 883), community adults (N = 214), and college students (N = 615), of predominantly White adults in the United States who completed an online survey. Exploratory and confirmatory factor analyses evaluated scale structure and identified four factors: social enhancement, mood enhancement, cognitive enhancement, and sexual enhancement. Positive outcomes were positively associated with recent use, controlling for expectancies and negative outcomes. Positive outcomes were also differentiated from positive expectancies and more influential in predicting typical use frequency. Findings indicate that the POCUS is psychometrically sound and clinically useful for measuring positive cannabis use-related outcomes among predominantly White adults in the United States.

Daily associations between resilience factors, substance use, and affect among sexual minority youth.

OBJECTIVE: Past research has highlighted that sexual minority youth (SMY) are at particular risk for heightened substance use compared to their heterosexual peers; however, few studies have investigated the associations between resilience factors and substance use among SMY. In the present preregistered study, we examined the associations among three different forms of resilience factors (i.e., general social support, lesbian, gay, bisexual, transgender, and queer (LGBTQ)-identity affirmation, LGBTQ community involvement) and alcohol, nicotine, and cannabis use, as well as on positive and negative affect. METHOD: SMY (n = 82, ages 15-19, 56.1% cisgender women, 84.4% White) completed a baseline assessment then a 30-day ecological momentary assessment study. Multilevel regression models evaluated within-day and between-person associations between resilience factors and odds of substance use (alcohol, nicotine, cannabis), substance use quantity on use days (alcohol, cannabis), positive affect, and negative affect. RESULTS: On the day level, general social support was associated with greater positive affect, lesser negative affect, and greater drinks on drinking days. LGBTQ-identity affirmation was associated with greater positive affect, lesser negative affect, and greater odds of nicotine use. LGBTQ community involvement was associated with greater positive affect. CONCLUSIONS: These results highlight the nuanced ways that resilience may engender more positive affect and reduce negative affect while simultaneously promoting substance use. Future research disentangling the mechanisms connecting resilience and substance use among SMY is necessary. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

A test of competing mediators linking trouble sleeping to cannabis use in adolescents and emerging adults.

This study examined day-level associations between trouble sleeping and three cannabis-use indices (likelihood/quantity of use and impaired control). We evaluated behavioral and cognitive mediators of the association between trouble sleeping and cannabis outcomes. Youth (N = 86, ages 15-24, 48.8% female, 58.8% White, 18.6% Latine) who regularly used cannabis were recruited for an intervention study. This preregistered secondary data analysis leveraged data from a 1-week ecological momentary assessment (EMA) study completed prior to intervention. Trouble sleeping, cannabis use, and impaired control over use were assessed each morning; negative affect, risk-taking propensity, and cannabis craving were assessed multiple times and aggregated to create a daily average. Multilevel structural equation modeling evaluated hypothesized temporally sequenced associations and putative mechanisms at the day (i.e., within) and person (i.e., between) level. In bivariate analyses at the person level, there were large-effect associations between trouble sleeping and craving and negative affect, and between craving and cannabis-use likelihood and quantity (rs from .34 to .48). In multilevel analyses at the day level, participants were less likely to use cannabis the next day after reporting more trouble sleeping (ß = -.65, p < .001). Trouble sleeping was not directly associated with subsequent cannabis-use quantity or impaired control, or indirectly via negative affect, risk-taking propensity, or craving. Trouble sleeping had differential relations with cannabis-use indices at the day and person levels. To promote youth health and reduce cannabis use, future research may consider the unique, person- and situation-driven mechanistic processes at play.

Psychometric properties of the family assessment task parental monitoring scenario among adolescents receiving substance use treatment.

INTRODUCTION: The Family Assessment Task (FAsTask) is an observer-rated parent-child interaction task used in adolescent substance use intervention. The parental monitoring component of the FAsTask is thought to provide an objective assessment of parental monitoring that can guide treatment planning and circumvent the potential limitations of self-report measures. Yet, the factor structure, measurement invariance, and concurrent validity of the parental monitoring FAsTask has not been evaluated; doing so is essential to effectively guide clinical care. This study examined if the parental monitoring FAsTask can be reliably administered across adolescent age and sex, and to identify which components of the parental monitoring FAsTask are most consistently associated with adolescent substance use. METHODS: The study pooled data from 388 adolescent-caregiver dyads across six separate clinical trials (adolescents [Mage = 15.7, 57.5% male, 61.9% White, 31.2% Latine]; caregivers [Mage = 42.14, 88.7% female, 72.7% White, 24.2% Latine]). Dyads completed the FAsTask and the Timeline Followback at baseline, prior to randomization. Analyses proceeded in three steps. First, exploratory factor analysis (EFA) was conducted in half of the sample, followed by a confirmatory factor analysis (CFA) in the second half of the sample. Second, measurement invariance was tested as a function of adolescent age and biological sex. Third, a series of structural equation models were used to assess the associations of each factor with alcohol use, binge drinking, and cannabis use. RESULTS: EFA and CFA indicated the presence of four factors (labeled Supervised/Structured, Active Monitoring, Task Engagement, and Parental Rules/Strategies). Evidence of measurement invariance was found across adolescent age and sex. The Supervision/Structure was negatively associated with adolescent alcohol use, binge drinking, and cannabis use. CONCLUSIONS: The parental monitoring FAsTask demonstrates validity and retains its structure across adolescent age and sex. Items focused on parental supervision and structure are most strongly associated with adolescent substance use and may best inform clinical care for adolescent substance use.

In the Presence of Parents: Parental Heterosexism and Momentary Negative Affect and Substance Craving Among Sexual Minority Youth.

PURPOSE: We examined the influence of parental heterosexism on in vivo negative affect and substance craving among sexual minority youth (SMY) who use nicotine and other substances, and if that relation was strengthened when in the presence of their parent(s). METHODS: SMY (n = 42, ages 15-19) completed baseline assessments, including experiences of parental heterosexism (PH), and a 30-day ecological momentary assessment. Ecological momentary assessment reports included affective states (i.e., anger, anxiety, depression), substance craving (i.e., nicotine, cannabis, alcohol), and other contextual factors (e.g., presence of parents). Multilevel logistic regression models evaluated the study hypotheses. RESULTS: PH was associated with greater odds of reporting in-the-moment anger, depression, cannabis craving, and alcohol craving. Parental presence was associated with lower odds of reporting anxiety or depression, and greater odds of reporting nicotine craving. There was a significant interaction when predicting the odds of reporting anxiety. For SMY low in PH, parental presence was related to lower odds of reporting anxiety. As PH increased, parental presence had diminishing associations with the odds of reporting anxiety. DISCUSSION: Parenting behaviors can serve as protective and risk factors for negative affect and substance craving among SMY. Improving family-based interventions for SMY may be integral for enhancing healthy development and reducing health disparities.

Does sleep relate to next-day cannabis use during treatment? Findings from an adolescent and young adult motivational enhancement and cognitive behavioral therapy plus topiramate intervention.

BACKGROUND: Interventions for youth cannabis use have limited efficacy. Sleep is likely to affect treatment response, as sleep difficulties are cross-sectionally associated with use and common during treatment. This analysis examined how sleep duration and subjective trouble sleeping related to next-day cannabis use among youth during cannabis treatment. METHOD: Participants (N=64) received a psychosocial intervention plus topiramate versus placebo while completing a 6-week ecological momentary assessment study. Time-varying effect modeling (TVEM) examined within- and between-person associations between sleep and cannabis use and how the strength of within-person associations varied over the course of treatment. RESULTS: TVEM resvealed that, between-participants, youth with longer average sleep duration used cannabis less often controlling for baseline cannabis use, topiramate, and weekend status. Daily within-person fluctuations in sleep duration and trouble were not associated with use. CONCLUSIONS: Findings suggest regularly shorter sleep may impede treatment outcomes. Adolescents who regularly have insufficient sleep durations likely need additional intervention to improve sleep difficulties in tandem with cannabis use reduction.

Personality Disorders, Risky Behaviors, and Adversity: The Moderating Role of Resilience.

Individuals with personality disorders (PDs) comprise 30% to 40% of individuals receiving mental health treatment. Treatment of PDs is exceedingly difficult; therefore, research has focused on PD etiology and preventative factors. One known influence on PD etiology is adverse childhood experiences (ACEs). ACEs are associated with increased prevalence of several health risk behaviors (HRBs), including engagement in substance use, criminal, and risky sexual behavior. One protective factor, childhood resiliency, predicts lower prevalence of PDs and engagement in HRBs. We hypothesized that increased prevalence of ACEs would predict higher levels of PD symptoms and HRBs engagement. Furthermore, we predicted that childhood resiliency would moderate the relation between ACEs, PD symptoms, and HRBs. In the present study, students (N = 531) completed the Adverse Childhood Experiences survey, the Self-Administered - Standardized Assessment of Personality Abbreviated Scale, and the Childhood Youth and Resiliency Measure-28. They also responded to questions about substance use, criminal, and sexual behavior which were used to define a latent HRB variable. Structural equation modeling was conducted to examine study hypotheses. As hypothesized, we found positive relations between ACEs, PD symptoms, and our HRB latent variable. Childhood resiliency moderated both ACE and PD symptom paths. At lower levels of reported ACEs, individuals high in childhood resiliency reported fewer PD symptoms and HRBs than individuals low in childhood resiliency. At high levels of ACEs, childhood resiliency did not serve as a protective factor. Additionally, study findings suggest that childhood resiliency factors are integral for protecting against the development of these disorders.

The Relation Between Impulsivity and Estimation of Marijuana Weight.

Until recently, marijuana research has often relied on self-reported frequency of use (e.g., days used per month). These estimations may oversimplify use at times, as they can only infer the quantity that one uses, rather than directly measure it. While some studies have estimated quantity (e.g., number of joints, grams), research has supported that user estimates of marijuana weight are often inaccurate and overestimate the true quantity. Since weight misestimation varies by participant, it may be important to identify individual difference factors (e.g., personality) that influence weight estimation. One such factor may be impulsivity, as it is known to relate to other marijuana-use measures (e.g., frequency, consequences). However, research has yet to examine the specific relation between impulsivity and misestimation of marijuana weights. The present study investigated impulsivity as a predictor of marijuana quantity estimation, using objectively weighed quantity data. We hypothesized that impulsivity facets would relate to marijuana quantity misestimation. We asked attendees at a marijuana- related event to roll a joint or pack a bowl, and then take, among a battery of measures, the SUPPS-P Impulsive Behavior Scale. We found that negative urgency, positive urgency, and lack of perseverance were not significantly associated with misestimation, while lack of premeditation was significantly negatively related to misestimation. Findings indicated that individuals who lacked in premeditation made more accurate quantity estimates than those higher in premeditation. Future directions should investigate the relation between impulsivity, marijuana intoxication, and marijuana quantity estimation.

Mechanisms of change in an adapted marijuana e-CHECKUP TO GO intervention on decreased college student cannabis use.

The objective of this study was to test indirect effects of the Marijuana e-CHECKUP TO GO program on college students' frequent marijuana use through decreased use in specific social and academic activities. 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.

Wielding a gun increases judgments of others as holding guns: a randomized controlled trial.

The gun embodiment effect is the consequence caused by wielding a gun on judgments of whether others are also holding a gun. This effect could be responsible for real-world instances when police officers shoot an unarmed person because of the misperception that the person had a gun. The gun embodiment effect is an instance of embodied cognition for which a person's tool-augmented body affects their judgments. The replication crisis in psychology has raised concern about embodied cognition effects in particular, and the issue of low statistical power applies to the original research on the gun embodiment effect. Thus, the first step was to conduct a high-powered replication. We found a significant gun embodiment effect in participants' reaction times and in their proportion of correct responses, but not in signal detection measures of bias, as had been originally reported. To help prevent the gun embodiment effect from leading to fatal encounters, it would be useful to know whether individuals with certain traits are less prone to the effect and whether certain kinds of experiences help alleviate the effect. With the new and reliable measure of the gun embodiment effect, we tested for moderation by individual differences related to prior gun experience, attitudes, personality, and factors related to emotion regulation and impulsivity. Despite the variety of these measures, there was little evidence for moderation. The results were more consistent with the idea of the gun embodiment effect being a universal, fixed effect, than being a flexible, malleable effect.

Who takes the trip? Personality and hallucinogen use among college students and adolescents.

Research examining hallucinogen use has identified potential benefits, as well as potential harms, associated with use. The acute effects of hallucinogen use can be intense, disorienting, cognitively impairing, and may result in perceptual changes mimicking aspects of temporary psychosis. Hallucinogen use may also lead to the onset of more chronic issues, such as Hallucinogen Persisting Perception Disorder, which impairs daily functioning even when sober. However, research on factors that predict who will misuse hallucinogens is an understudied area. In particular, while sensation seeking, impulsivity, and emotion dysregulation have all been shown to be predictive of problematic substance misuse, there is almost no research on how these personality variables predict hallucinogen use. The present study assessed how these personality traits predicted hallucinogen use in a sample of college undergraduates (N = 10,251) and a sample of adolescents in an inpatient residential psychiatric hospital (N = 200). Results indicated that facets of sensation seeking, impulsivity, and emotion dysregulation positively predicted ever having used hallucinogens, earlier initiation of use, and lifetime use among college students. Findings also indicated that facets of sensation seeking, impulsivity, and emotion dysregulation positively predicted having ever used hallucinogens in the adolescent inpatient sample. Results highlight the need for more research on who is likely to misuse hallucinogens. If confirmed in future research, the findings presented herein indicate viable personality variables as predictors. This is especially important as there has been a recent explosion of research on the positive benefits of therapeutic hallucinogen use.

A mediated multigroup model examining marijuana use consequences by sexual orientation in us college students.

Marijuana use holds a curvilinear relation to sexual orientation, whereby bisexual individuals reporter higher frequency of use than exclusively hetero- or homosexual individuals. This relation differs by gender, with more pronounced differences among women. Bisexual individuals are at greater risk for negative consequences of marijuana use, such as dependence. To mitigate potential risks, individuals employ protective behavioral strategies (PBS). While differences in use are known, research has yet to examine if consequences and PBS use vary by sexual orientation. This study seeks to address the relations between sexual orientation, consequences, gender, and PBS. It was hypothesized that orientation would be associated with consequences, mediated by PBS, and these relations would vary by gender. College students (N = 8141) from 11 different universities completed an online survey measuring marijuana consequences, PBS use, and sexual orientation. A final analytic sample (n = 2091) was composed of participants who indicated past 30-day marijuana use (60% women, 64% White, mean age 19.92). Path analysis was used to test all study hypothesis. Results indicated a curvilinear relation between sexual orientation and consequences among men, however not women. Moreover, PBS use mediated the relation between orientation and consequences among men, and negatively predicted consequences among women. Conclusions include that mixed sexual orientation men experience higher consequences through lower PBS use. For women, PBS use buffers against consequences. These findings reflect a general effectiveness of PBS use for mitigating negative marijuana-related consequences. The implications of these results are discussed.

Reefer madness or much ado about nothing? Cannabis legalization outcomes among young adults in the United States.

In 2012, Colorado became one of the first two U.S. States to legalize cannabis for recreational use for adults 21 and older. Given that cannabis use holds potential physical and mental health risks, particularly among adolescent users, concerns have grown regarding changes in use following this change in policy. Studies examining medical cannabis legalization have found inconsistent changes in cannabis use and prevalence of dependence following medical implementation. However, recreational legalization holds potential unique changes, such as increased availability and social acceptance, as well as decreased price and perceived harm of use. There also may be increased interest in moving to Colorado related to the changes in cannabis laws. Based on past literature, two hypotheses were made for this study. First, college student cannabis use would increase after recreational legalization, however just for those 21 years old and older. Second, there would be a positive relation between the influence of cannabis legislation on out-of-State student's decision to attend a Colorado university and their cannabis use. Data from 5241 undergraduate students was available to test study hypotheses using Pearson's Chi-square, negative binomial regressions, and path analysis. Results indicated that cannabis use increased since recreational legalization for all students, but more so for those over 21 years. No differences in past month use frequency were found between pre- and post-legalization. Influence of cannabis laws on non-resident student's decision to attend a Colorado college predicted lifetime and past 30-day use. Additionally, out-of-State students reported higher past 30-day use than in-State students. These findings may help inform other States considering recreational legalization of potential outcomes, as well as potential interventions.

Marijuana eCHECKUPTO GO: Effects of a personalized feedback plus protective behavioral strategies intervention for heavy marijuana-using college students.

BACKGROUND: Marijuana use is common among U.S. college students. 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. METHODS: 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 intervention effects. RESULTS: Marijuana eCHECKUPTO GO participants reported decreases in estimated use prevalence (i.e., descriptive norms), self-reported hours high per week, days high per week, periods high per week, and weeks high per month. Sex moderated intervention effects on the use of PBS such that females in the PF condition increased their use of PBS more than males. CONCLUSION: Results demonstrate preliminary support for the adapted Marijuana eCHECKUPTO GO in reducing marijuana use for "heavy college-aged users". Future research should test adapted Marijuana eCHECKUPTO GO sustained effects over time, and examine whether program effects on harm reduction manifest after sustained (e.g., booster) program implementation.

Is 4/20 an Event-Specific Marijuana Holiday? A Daily Diary Investigation of Marijuana Use and Consequences Among College Students.

OBJECTIVE: Given the popular association between April 20 ("4/20") and marijuana, the present study examined marijuana use and consequences on 4/20 compared with other days in order to test whether 4/20 is a high-risk, event-specific marijuana use holiday among college student marijuana users. METHOD: Fifty-nine college student marijuana users from three different, large U.S. universities located in Virginia, New Mexico, and Colorado completed daily brief surveys (<10 minutes) over a 12-day (April 15-April 26) period assessing prior-day marijuana use (i.e., percentage of users who consumed marijuana, number of unique marijuana use sessions, subjective high/intoxication while under the influence of marijuana, and number of grams of marijuana consumed) and marijuana-related consequences. RESULTS: Using oneway repeated-measures analyses of variance, we found that (a) 50% of students reported using marijuana on 4/20, which was significantly more than weekdays (28%) and weekend days (37%); (b) students reported a significantly higher number of unique marijuana use sessions on 4/20 (M = 1.47) compared with weekdays (M = 0.91); and (c) students reported a significantly higher number of grams consumed on 4/20 (M = 0.79) compared with weekdays (M = 0.35) and weekend days (M = 0.47). CONCLUSIONS: Our study provides preliminary support that 4/20 is a day associated with increased marijuana use but provides little evidence for an association with more problematic use.

The curvilinear effects of sexual orientation on young adult substance use.

Alcohol, tobacco, and marijuana are commonly used by adolescents and linked with harmful health-related outcomes (e.g. injury, dependence). Moreover, heavy episodic (binge) drinking predicts more severe consequences. When examined by sexual orientation, highest rates of substance use have been found among bisexual individuals, with lower use at either end of the spectrum. When examined also by sex, this curvilinear trend is maintained among women but not men. These substance use patterns were identified using group differences (i.e. heterosexual vs. bisexual vs. homosexual). However, evidence suggests that sexual orientation is a continuous, not categorical, variable. This study examined the hypotheses that sexual orientation and commonly used substances (heavy episodic drinking, tobacco, marijuana) would have a quadratic relation among women, but not among men. Six negative binomial regressions tested study hypotheses using data from 7372 participants. Results indicated that sexual orientation had a quadratic relation with heavy episodic drinking, tobacco use, and marijuana use among women, as hypothesized. Additionally, a quadratic relation was found between marijuana use and sexual orientation among men. These findings indicate that women identifying as having mixed sexual orientation are at higher risk than women at either end of the sexual orientation continuum for substance use and related negative outcomes. For men, this is only true for marijuana use and resultant negative consequences. This observed increased use may relate to coping with increased stressors, which has been linked to more problematic use. By better understanding LBG identities and behaviors, clinicians and researchers will be more adept at identifying risk factors and better understanding the nuances across the sexual orientation spectrum.
