Comparison of subjective response to alcohol in Caucasian and Hispanic/Latino samples

Using Young Adult Language to Describe the Effects of Simultaneous Alcohol and Marijuana Use: Implications for Assessment

Introduction: Prevalence of alcohol and marijuana use is highest in young adulthood and an increasing number of young adults report simultaneous alcohol and marijuana (SAM) use, which is consistently linked with numerous negative consequences. To better understand reasons for engaging in SAM use and to refine measurement of subjective effects of SAM use, this study aimed to identify (1) how young adults describe subjective experiences during a SAM use occasion and (2) how language describing subjective effects changes as a function of level of alcohol and marijuana use. Methods: Using Amazon's Mechanical Turk (MTurk), 323 participants (53.6% women, 68.4% White, M age = 23.0 years) who reported past-month heavy episodic drinking and past-month SAM use were asked to list words to describe how they feel when using only alcohol, only marijuana, and various combinations of alcohol and marijuana. Results: SAM use language varied as a function of age and substance use behavior but was not associated with sex or race. Large differences in the terms used to describe subjective effects were observed when comparing different combinations of alcohol and marijuana use; most notably the term "cross-faded" appeared primarily when engaging at the heaviest combinations of alcohol and marijuana. Conclusion: Young adults have a wide range of vocabulary for describing subjective effects of SAM use, and subjective effects vary as a function of the level of each substance used. Future research should consider integrating such contemporary language when measuring subjective effects of SAM use.

Measuring subjective alcohol effects in daily life using contemporary young adult language

Young adults' subjective feelings of alcohol's effects are a key predictor of engagement in risky behavior such as deciding whether to drive after drinking. To best inform prevention messaging and tailor intervention techniques that target high-risk drinking, it is critical that our measurement best captures subjective feelings. Standard sliding scales (0-100 rating of, "how drunk do you feel?") may have some challenges with distinguishing between levels of subjective responses to alcohol. The current daily diary study compared the utility of the standard sliding scale to a newly developed sliding scale that uses contemporary, crowd-sourced language from young adults as evenly spaced anchors (slightly buzzed, tipsy/"happy," drunk, and wasted) along a continuum of subjective effects of alcohol. Participants were 154 young adult substance users (58% women) who completed up to 14 consecutive daily reports of their substance use behavior. The four-anchored sliding scale performed similarly well as the standard scale in predicting alcohol use outcomes while showing the advantages of recording higher mean values/standard deviations and demonstrating that participants used the anchors to denote varying degrees of subjective effects. Findings suggest that the four-anchored subjective alcohol effects sliding scale is a viable alternative to the standard scale. By providing evenly spaced anchors that reflect incremental differences in language young adults use to describe their subjective states, the proposed scale may provide a guide for participants to indicate how they feel after drinking and may better capture variability in alcohol's effects.

The language of subjective alcohol effects: Do young adults vary in their feelings of intoxication?

Among young adults, subjective feelings of alcohol's effects often guide risky decision making. The majority of studies measuring subjective effects have used singular indices ("How drunk do you feel?") which limits our understanding of young adults' full range of subjective states and their individual differences in subjective effects language. Toward a more in-depth understanding of the heterogeneity among alcohol users based on their subjective experiences of alcohol's effects, we identified latent classes of individuals based on their self-generated language describing feelings after drinking and compared these classes across demographic and drinking characteristics. Participants (N = 323, 54% women, 68% White, Ages 18-25 years) were recruited using Amazon's Mechanical Turk (MTurk). Participants listed words they would use to describe how they feel after drinking low, moderate, and heavy amounts of alcohol. Four latent classes of young adults emerged: "happy drinkers" (31%) primarily reported feeling "happy" when drinking; "relaxed drinkers" (24%) reported feeling happy, relaxed, and buzzed; "buzzed drinkers" (18%) reported feeling buzzed and dizzy; and "multiexperience drinkers" (27%) reported feeling buzzed, tipsy, drunk, and wasted. Relaxed drinkers indicated heavier alcohol use and buzzed drinkers reported lower drinking frequency. Classes did not differ by demographic characteristics. Young adult alcohol users can be distinguished based on the language they use to describe their feelings of intoxication. To continue to advance our understanding of subjective effects, it is necessary to take into account the full range of language used and how this language differs by young adult drinking behavior.

Putting things in context: Longitudinal relations between drinking contexts, drinking motives, and negative alcohol consequences

Recent studies suggest that solitary (but not social) drinking may confer risk for negative alcohol consequences via beliefs about alcohol's ability to reduce tension, and explicit motivations to drink to cope with negative mood states. However, because prior studies are largely cross-sectional, it is unclear if tension reduction expectancies and drinking to cope are antecedents or consequences of solitary drinking. The current study aimed to address this gap in the literature using prospective data (3 waves across 12 months) from a sample of moderate to heavy drinking young adults. Data were drawn from a larger investigation of contextual influences on subjective alcohol response. Participants (N = 448) reported on alcohol use in multiple drinking contexts and tension reduction expectancies at baseline (T1), drinking motives at a 6-month follow-up (T2), and past-month negative alcohol consequences at a 12-month follow-up (T3). We examined potential indirect effects of drinking contexts on negative consequences operating through alcohol expectancies and drinking motives. Solitary drinking was indirectly associated with later negative consequences through stronger coping motives, although tension reduction expectancies did not serve as a significant mediator. Social drinking was not directly or indirectly related to later alcohol consequences. Results suggest that solitary drinking contexts confer risk for negative consequences through coping motives, and that these effects are invariant across sex, race, and ethnicity. These findings have important clinical implications as they suggest that targeting solitary drinkers for skills-based coping interventions may reduce risk for a developmental trajectory toward negative alcohol consequences.
