Subtypes of Alcohol Expectancies Are Differentially Associated With Alcohol Use for Bisexual and Heterosexual Women.

Background: Bisexual women, compared to heterosexual women, report greater amounts of alcohol use and heavy drinking. Alcohol expectancies (i.e., beliefs about alcohol outcomes) are a strong predictor of alcohol use, but few studies have examined the importance of alcohol expectancies in relation to alcohol use among bisexual women specifically or in comparison to heterosexual women. Objectives: The current study examined 262 heterosexual and 225 bisexual women using an online survey about alcohol use, sexual risk-taking, and alcohol expectancy subtypes (sexuality, tension reduction, and aggression). Results: Compared to heterosexual women, bisexual women reported greater sexuality and tension reduction expectancies after accounting for their level of drinking, but groups did not differ on aggression expectancies. Moreover, sexual identity status moderated the associations between sexuality and tension reduction expectancies and alcohol use, respectively. Specifically, our study findings suggested that sexuality and tension reduction alcohol expectancies were more strongly tied to alcohol use among bisexual women than heterosexual women. Conclusions: Taken together, in our study, bisexual women held stronger sexuality and tension reduction expectancies, as compared to heterosexual women. Interventions targeting alcohol expectancies may be considered when tailoring intervention content for this population.

Latent profiles of impulsivity facets and associations with drinking behaviors.

BACKGROUND: Impulsivity is positively associated with alcohol use. However, scant research has used person-centered approaches to examine how patterns of impulsivity facets may be associated with alcohol-related outcomes. Consequently, the present study sought to (1) identify latent groups of individuals who share similarities based on the five facets of impulsivity assessed using the UPPS-P scale (positive urgency, negative urgency, premeditation, perseverance, and sensation seeking) and (2) examine differences between latent profiles on alcohol use (i.e., typical alcohol quantity, typical alcohol frequency, binge frequency), alcohol consequences, and drinking motivations. METHODS: Participants were 360 (M age = 21.83; 78.9 % female; 49.4 % racial/ethnic minority) college students who reported weekly drinking over the prior 30 days. They completed questionnaires of impulsivity, alcohol use behaviors, alcohol consequences, and drinking motivations. Latent profile analysis was used to identify classes based on the five UPPS-P facets as indicators. RESULTS: Results revealed that three classes best fit the data: Highest UPPS-P (14.4 %); Moderate UPPS-P (56.9 %); and Lowest UPPS-P (28.6 %). Profiles did not vary on drinking behaviors (quantity, frequency, or binge frequency), but significant differences were observed on alcohol consequences and drinking motivations, specifically coping and conformity motives. CONCLUSIONS: Our data demonstrated that UPPS-P facets tend to cluster together, and patterns may pose risk for consequences and negative motives for drinking. The current study contributed to the conceptualization of impulsivity by identifying specific impulsivity typologies that may be used to target individuals at elevated risk for alcohol consequences.
