Perceived helpfulness of alcohol protective behavioral strategies and consequence severity: A person-centered analysis

Objective: College students report high rates of alcohol use and negative alcohol-related consequences (ARC). Many studies document that protective behavioral strategy (PBS) use is negatively associated with ARC. Few studies examine consequence severity and PBS helpfulness, both of which may provide nuance to this relationship. Participants and method: The current study used latent profile analysis to examine variability in PBS use, PBS helpfulness, ARC count, and ARC severity patterns among college students (n = 1156). We identified latent profiles and differences in alcohol use and drinking motives across profiles. Results: Three profiles best represented the data: (1) high PBS/low consequences, (2) moderate PBS/moderate consequences, (3) low PBS/high consequences. Conclusions: College students endorsing stronger drinking motives might be less likely to use and select helpful PBS and might experience more severe ARC. Results suggest that simple modifications to common measures can add depth of understanding and nuance to the examination of alcohol-related behaviors.

You're Stressing Me Out: The Secondhand Effects of Alcohol

Introduction: Secondhand effects of alcohol use (SEA) are adverse consequences experienced by an individual due to another's drinking (i.e., study/sleep interrupted, being insulted or humiliation, sexual assault or rape). SEA is a serious public health concern among college students due to its serious consequences and high prevalence (60-84%). The present study examined the associations among SEA, personal alcohol use, depression, anxiety, and stress. Methods: 836 students completed an online survey that assessed for study variables. Results: SEA significantly predicted all outcomes with those endorsing SEA reporting higher levels of depression, anxiety, and stress. Moreover, participants who endorsed SEA also reported 30% more frequent binge drinking and 18% more drinks on their heaviest reported drinking day. Conclusions: Findings indicate that the experience of SEA is a risk factor for poor mental and behavioral health outcomes among college students.

Using Latent Profile Analysis to Examine Cannabis Use Contexts: Associations with Use, Consequences, and Protective Behaviors

OBJECTIVE

College students represent a large portion of the population, and report high rates of cannabis use and related negative outcomes, including interpersonal problems, risky behaviors, or physical dependency. The contexts in which students use cannabis (e.g., at a party, when feeling down or depressed, after a fight with a loved one) likely affect their risk of experiencing consequences. We aimed to discern profiles of cannabis use contexts and compare profiles on use frequency, consequences, and the use of cannabis protective behavioral strategies (PBS).

METHOD

College students were surveyed regarding their cannabis use contexts, frequency, consequences, and PBS use (n = 265; female = 72.8%). We used Latent Profile Analysis to identify patterns of cannabis use contexts and auxiliary testing to compare profiles on use frequency, consequences, and PBS use.

RESULTS

Our examination revealed three latent profiles of cannabis use. The Social Use Profile was associated with use in predominantly social/uplifting contexts. The Physical & Emotional Pain Profile was also associated with use in these contexts but was defined by additional use in response to pain. The All Contexts Profile was associated with frequent use in all contexts, including those that were least endorsed by the other profiles. Profiles differed in cannabis use frequency, PBS use, and the number of consequences experienced, such that profiles were more likely to be associated with more frequent cannabis use, higher risk of experiencing use-consequences, and using fewer PBS as the number of use contexts increased across the profiles.

CONCLUSIONS

The contexts in which people use cannabis are associated with cannabis risk and protection. Prevention and intervention efforts may benefit from considering contexts of cannabis use.

Results of a randomized controlled trial of the cannabis eCHECKUP TO GO personalized normative feedback intervention on reducing cannabis use, cannabis consequences, and descriptive norms

BACKGROUND

The prevalence of cannabis use disorder and its negative consequences among young adults has highlighted the need for prevention and early intervention programs. However, low treatment prevalence persists due to factors such as lack of perceived need, concerns about stigma, and limited access to treatment. To address these barriers, web-based cannabis interventions have been developed, but their efficacy remain limited. This study aims to evaluate the cross-site efficacy of the Cannabis eCHECKUP TO GO program, a web-based Personalized Normative Feedback and Protective Behavioral Strategies intervention for reducing cannabis use frequency and consequences in college students with willingness to change.

METHODS

Participants were 781 students from three universities (two in Canada, one in the US) who reported using cannabis in the past month and expressed interest in reducing or engaging in safer cannabis use. The study randomly assigned them to either an experimental group that received personalized normative feedback or a control group that received information on healthy stress management. The study collected follow-up data 4 weeks after the initial intervention and measured participants' frequency of cannabis use, number of cannabis consequences, descriptive and injunctive norms at both time points.

RESULTS

The results showed no significant reductions in cannabis use or negative consequences of use. However, students who received personalized normative feedback experienced a significant reduction in descriptive norms related to cannabis use, to be more in line with actual use.

CONCLUSION

This study suggests that more targeted interventions may be necessary for university students who are already using and seeking help to reduce their use.

Expectancies that Predict Cannabis Initiation in Response to Legalization

Background: Recent and prospective changes to nonmedical/recreational cannabis laws in the United States and abroad raise questions about how legalization may influence cannabis use behaviors. Objectives: In the current study, we examined links between legalization, context-specific likelihood of using cannabis, and cannabis expectancies using cross-sectional survey data from 121 college students who had never used or were abstaining from cannabis in a U.S. state where laws prohibit nonmedical cannabis. Results: We found that across scenarios, 61% of students reported they would be more likely to use cannabis if it were legal. Social/sexual facilitation expectancies predicted a higher likelihood of using cannabis after legalization in a social context. Relaxation/tension reduction expectancies predicted a higher likelihood of using in an anxiety relief context. Perceptual/cognitive enhancement expectancies predicted a higher likelihood of using in a pain relief context. Cognitive/behavioral impairment expectancies predicted a lower likelihood of using in social, pain relief, relaxation, and concert contexts. Global negative effects expectancies predicted a lower likelihood of using in relaxation and concert contexts. Conclusions: Our findings suggest that among college students who do not use cannabis, expectancies are linked to cannabis use likelihood in certain contexts if cannabis were legal. This work highlights cannabis expectancies and contexts as possible targets for evidence-based public health education and clinical prevention initiatives related to the potential increase in cannabis use associated with cannabis policy implementation. College students may benefit from initiatives that address cannabis expectancies and enhance harm reduction skills to help them effectively navigate contexts in which cannabis is available to them.

Identifying Three Psilocybin Use Patterns by Frequency and Quantity

OBJECTIVE

Patterns of psilocybin use in non-clinical settings are not well described in the literature. Psilocybin use can involve infrequent, large (i.e., macro) doses that produce hallucinogenic effects. In addition, some people report psilocybin use at particularly small (i.e., micro), sub-perceptual doses. Given the heterogeneity in reported use metrics, we sought to determine whether there are identifiable patterns of psilocybin use based on participants' self-described typical use frequencies and quantities and to describe how demographic characteristics are associated with each pattern of use.

METHOD

Participants were recruited from online communities via Reddit.com. We used Latent Profile Analysis to discern psilocybin use patterns defined by frequency and quantity of use. The analytic sample consisted of 664 participants (75.6% US residents; 83.1% white; 67.2% male).

RESULTS

The Chipper Profile (18%) was associated with approximately 1-4 annual uses and using between 0.75g and 1.0g of dehydrated, psilocybin-containing mushrooms. The Tripper Profile (64%) was associated with approximately 2-6 annual uses and self-reported use quantities between 2-4g. The Microdoser Profile (18%) was related to substantively higher psilocybin use frequencies than the other profiles (between 2-4 times a week) and a lower range of preferred quantities (between 0.25g - 0.75g). Additionally, profiles differed by certain demographic measurements, lifetime psilocybin use, and timing of psilocybin use.

CONCLUSIONS

Psilocybin use in non-clinical settings is heterogeneous. We identified three profiles that differed on frequency and quantity of use and their associated demographic characteristics. Next steps are to identify factors that affect one's likelihood of experiencing particular use outcomes and to explore use variability.

A cross-sectional examination of race, gender, and intersectionality on protective behavioral strategies and alcohol outcomes among Black and White college students

College students consistently report problematic alcohol use (e.g., excessive drinking). Protective behavioral strategies (PBS) are behaviors for reducing alcohol use and/or problems and are negatively associated with alcohol misuse among college students. Studies suggest PBS are used more often and/or more effectively by female individuals. Additionally, examinations specifically between Black and White students have yielded mixed findings and are typically underpowered. Scant studies have investigated the intersectionality between race and gender or examined perceived effectiveness of PBS use related to alcohol outcomes. The current cross-sectional study examined if (a) race, (b) gender, and (c) their interaction moderate the associations between perceived effectiveness of PBS use on PBS use (a path) and between PBS use on alcohol outcomes (i.e., alcohol quantity, peak drinks, and problems; b path). A sample size of N = 528 college drinkers ages 18-24 years old (Mage = 19.85; 52.5%, Black, 40.3% White) completed an online survey and were used for analyses. A series of moderated mediation models were conducted. Race did not moderate the a or b paths. The positive association for the a path as well as the indirect effect of PBS perceived effectiveness on lower alcohol outcomes through PBS use were stronger for female students than male students. The intersectionality examination indicated a stronger association between more PBS use and lower consumption, specifically for White male students, and lower problems for Black female students. More attention is needed toward considering intersectionality when identifying at-risk groups and tailoring alcohol intervention efforts.

Latent profiles of cannabis use, protective behavioral strategies, and health beliefs in college students

College student cannabis use is prevalent and heterogeneous, with some students experiencing cannabis-related problems. Cannabis protective behavioral strategies (PBS) are cognitive-behavioral strategies associated with reduced cannabis use and problems. There is a need for theory-informed and person-centered research to better understand cannabis PBS. The current study applied the health belief model (HBM) and latent profile analysis to discern patterns of cannabis use, PBS, and health beliefs among college students. Students (n = 164; M_age = 18.8; 53% female) who endorsed past-month cannabis use completed an online survey between September and November 2017. The 3-profile model best fit the data. Profile 1 (24.3%) represents the "infrequent use/high protection" profile characterized by using cannabis about 1-9 times, high PBS use, high perceived threat and benefits, and moderate perceived barriers. Profile 2 (38.1%) represents the "occasional use/moderate protection" profile characterized by using cannabis about 20-59 times, moderate PBS use, moderate perceived threat and benefits, and low perceived barriers. Profile 3 (37.6%) represents the "frequent use/low protection" profile characterized by using cannabis about 80 or more times, low PBS use, low perceived threat and benefits, and high perceived barriers. Profiles did not differ by age, ethnicity/race, sex, or college year, though varied significantly by age at first cannabis use, cannabis availability, cannabis problems, use frequency, and use context. Results provide preliminary support for distinct patterns of cannabis use, PBS, and health beliefs that align with the HBM. Results highlight the importance of considering how students perceive cannabis PBS and problems and how those beliefs may influence their PBS and cannabis use.
