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.

Characterizing the dimensions of positive emotion functioning in young adult alcohol use and alcohol-related problems.

Emotional functioning figures prominently in most contemporary models of alcohol use (Kassel & Veilleux, 2010). These models posit that alcohol use becomes reinforced due to its ability to regulate a person's affect (Sher & Grekin, 2007). A growing body of literature suggests that for youth, positive reinforcement (i.e., using alcohol to enhance positive feelings or to increase their duration) is a leading mechanism facilitating increased use (Emery & Simons 2020; Howard et al., 2015). However, few, if any, studies have examined the unique associations between multiple indicators of positive emotional functioning and alcohol use as well as alcohol-related problems. We aimed to fill this gap by using secondary data from large college student sample (N = 402) to characterize the unique associations between trait indicators of positive emotional functioning (i.e., positive affect, anhedonia, savoring, positive emotion dysregulation) and alcohol use as well as alcohol-related problems. Results indicated trait positive emotion dysregulation (difficulty managing intense positive emotions) was positively related to both alcohol consumption (IRR = 1.03, p =.019) and alcohol-related problems (IRR = 1.03, p =.001). Interestingly, trait savoring (i.e., ability to increase the intensity/duration of positive emotions) was positively related to alcohol consumption (IRR = 1.18, p =.049) and inversely related to problems (IRR = 0.86, p =.019). None of the other positive emotion indicators were significantly associated with either alcohol use or problems.

Discrete emotions and global affect: Applying empirically driven approaches to experience sampling data to model state and trait affective structure and affect-alcohol use associations in a heavy drinking young-adult sample.

Affective functioning is central to most contemporary models of alcohol use. However, the affective structure at the within- and between-person levels is rarely investigated nor is the differential predictive value of specific affect dimensions assessed across state and trait formats. We examined a) the structure of state and trait affect using experience sampling methodology (ESM) and b) predictive associations between the empirically derived affect facets and alcohol use. Participants were 92 heavy drinking college students aged 18-25 who completed 8 momentary assessments of their affect and drinking a day for 28-days. We found evidence for a single positive affect factor at both the within- (i.e., state) and between-person (i.e., trait) levels. We found a hierarchical factor structure for negative affect, represented by a general, superordinate dimension as well as facet-level sadness, anxiety, and anger dimensions. Associations between affect and alcohol use differed across trait and state levels and across specific types of negative affect. Lagged state positive affect and sadness as well as trait positive affect and sadness were inversely associated with drinking. Lagged state anxiety and trait general negative affect were positively associated with drinking. Thus, our study demonstrates how associations between drinking and affect can be studied in relation to general (e.g., general negative affect) and more specific aspects of affective experiences (e.g., sadness versus anxiety) concurrently within the same study and across trait and state levels of assessment.

Family ties: examining family functioning and alcohol use among American Indian youth.

Purpose: This study aims to examine a second-order latent variable of family functioning built from two established protective factors for American Indian (AI) youth, i.e. family cohesion and parental monitoring. This study then examines if family functioning is related to alcohol use frequency or age of initiation for AI youth. Additionally, this study examines if family functioning served as a moderator for the risk factor of peer alcohol use. Design/methodology/approach: Data came from the 2021 Our Youth, Our Future survey. Participants were 4,373 AI adolescents from Grades 6-12 across the contiguous USA. Structural equation modeling (SEM) was used to test the latent variable of family functioning. Structural paths and interaction terms between peer use and family functioning were added to the SEM to explore direct and moderating effects. Findings: Family cohesion and parental monitoring were best represented by a second-order latent variable of family functioning, which was related to later initiation and lower alcohol use frequency. Practical implications: The findings regarding the initiation of alcohol use may be applicable to prevention programs, with family functioning serving as a protective factor for the initiation of alcohol use. Programs working toward alcohol prevention may be best served by focusing on family-based programs. Originality/value: The latent variable of family functioning is appropriate for use in AI samples. Family functioning, which is an inherent resilience factor in AI communities, was shown to be protective against harmful alcohol use behaviors.

The secondhand effects of alcohol use and the risks of drinking to cope.

Objective:The secondhand effects of alcohol use (SEA) are adverse consequences caused by another's drinking. This study explored the relationship among the experience of SEAs, alcohol use, and alcohol related consequences (ARC). In addition, we examined whether coping (i.e., adaptive, maladaptive, substance use coping, maladaptive coping without substance use items) served as a moderator of SEA effects on alcohol outcomes. Method: 1,168 students completed a survey assessing SEA, alcohol outcomes, ARC, and coping strategies. Results: SEA was significantly positively associated with alcohol use (RRheavydrinking = 1.05, SE = 0.005, p < .01; RRAUDIT = 1.04, SE = .005, p < .01) as well as ARC (RR = 1.06, SE = .005, p < .01). Various forms of maladaptive coping moderated the relationship between SEA and alcohol outcomes. Conclusion: This study provided evidence for a relationship between SEA and more alcohol use and ARC. This relationship was exacerbated by maladaptive coping.

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.
