What you think and where you drink: Context, alcohol outcome expectancies, and drinking behavior

Distress tolerance, coping motives, and alcohol craving and consumption: Two experiments testing momentary responses to a mood induction

BACKGROUND

The current studies examined the relationship between state and trait distress tolerance (DT), drinking-related variables (alcohol craving and consumption), and the moderating role of drinking to cope with negative affect (i.e., coping motives).

METHODS

Study 1 was a laboratory-based experiment. Participants (n=71) completed measures of trait DT, craving, coping motives, and affect valence prior to a negative mood induction task. Post-mood induction, participants completed measures of affect valence, alcohol craving, and state DT. Next, participants completed an alcohol taste task, measuring alcohol consumption. Study 2 was completed online. Participants (n=592) completed the same pre- and post-mood induction measures as study 1, but were randomized to a mood condition (neutral, negative, or positive). Study 2 did not include alcohol consumption.

RESULTS

Negative mood induction lowered reported affect in both studies. In study 1, higher coping motives predicted increased craving in response to negative mood induction but state and trait DT did not predict craving change alone. Contrary to our hypothesis, individuals with higher coping motives showed a positive relationship between trait DT and craving. Analyses predicting alcohol consumption were not significant. In study 2, lower trait DT predicted post-mood induction craving prior to inclusion of interactions in the model. Higher coping motives were the strongest and most consistent predictor of craving. Other predictors (state DT, mood condition) and interaction terms were not significant.

CONCLUSIONS

Findings broadly align with previous research suggesting that coping motives are predictive of craving and indicate that trait DT may also impact craving.

Drinking games among university students in five countries: Participation rates, game type, contexts, and motives to play

Most published studies, regarding students' participation in drinking games (DGs), originate from the United States of America (USA). This study extends research to the United Kingdom (UK) and countries of mainland Europe. University students from five countries completed an anonymous online questionnaire which included measures of the frequency of DG participation, along with types, contexts and motives for participation. Responses are compared by the gender, and country of domicile of the participants. The study is based on the results of the questionnaire administered to 306 Social Work students from five universities/countries of which 72.2% are females, with a mean age of 22.6 years. This included students in Austria, Germany, the Netherlands, the UK and the USA. A high proportion of students, irrespective of gender, or country of domicile, stated that they participated in DGs. To 'meet people' and 'to get drunk' are the most important reasons stated for DG participation. Less benign motives, to 'control others' or 'get other people drunk', are reported as 'not important'. The most common types of DGs were consumption and team DGs. The pre-partying involved in DGs and associated consequences show important targets in alcohol harm minimization interventions. Harm minimization/public health messages regarding safer drinking need to recognize that younger students often feel they are immortal and do not fully appreciate risks and adverse effects of DGs and drink to have fun and be sociable.

Personalized feedback tempers weekend increases in alcohol use among nonstudent emerging adult drinkers

A common pattern of problematic alcohol consumption among emerging adults consists of little to no drinking during the week, with heavy drinking episodes on the weekend. However, little is known about whether brief alcohol interventions exert impact on decreasing weekend drinking escalations or simply overall consumption throughout the week. A recent randomized controlled trial of heavy drinking emerging adult nonstudents (N = 164) demonstrated the efficacy of a personalized feedback intervention (PFI). Specifically, the PFI was associated with reduced overall alcohol consumption relative to assessment-only controls. However, it is not clear if patterns of weekend drinking escalation may have been disrupted by the intervention. The current study was a follow-up analysis of the parent trial. Using retrospective daily drinking data provided at each timepoint (up to 9-months), data were coded to reflect condition, time (coded to capture initial changes post-intervention as well as long-term maintenance), and day of the week (coded to capture weekend versus weekday). A multilevel negative binomial hurdle analysis was conducted, yielding two sets of results: 1) predicting the probability of a non-drinking day, and 2) predicting number of drinks consumed. Although the three-way interaction was not significant, 2 two-way interactions indicated that weekend increases in drinking were less steep over time for both groups, and less steep for PFI participants. In addition, the higher weekend likelihood of drinking was decreased over time for both groups. Steep weekend increases in drinking were disrupted over time, particularly among PFI recipients. Personalized feedback may be effective at helping nonstudent emerging adults avoid high risk drinking situations.

I drink alone: Mechanisms of risk for alcohol problems in solitary drinkers

Although solitary drinking is less common than social drinking, it may be uniquely associated with heavy drinking and alcohol-related problems. There is also evidence that drinking contexts impact both expected and experienced alcohol effects. In particular, solitary drinking may be associated with an increased likelihood of drinking for negative reinforcement (e.g. to relieve stress). The current study examined how drinking context influences tension reduction expectancies and drinking motives, and the extent to which expectancies and motives mediate the link between solitary drinking and alcohol-related problems. We hypothesized that solitary drinking would be associated with greater tension reduction expectancies and coping motives which, in turn, would be associated with more alcohol related problems. Data were from 157 young adult moderate to heavy drinkers (21-30 years of age, 57% male) who completed baseline assessments in an alcohol administration study. A path model in Mplus tested the hypothesized mediated effects. Findings largely supported study hypotheses with significant indirect effects of solitary drinking (but not social drinking) on alcohol problems through stronger tension reduction expectancies and coping motives, though an indirect path through coping motives (but not expectancies) was also identified. Multi-group models by gender and race/ethnicity found that models operated similarly for men and women and for Non-Hispanic Caucasian and Racial/Ethnic Minority participants. The results provide important information about potential mechanisms through which solitary drinking may contribute to alcohol problems. These mechanisms represent potential targets of intervention (e.g. tension reduction expectancies, drinking to cope) for solitary drinkers.

Context Matters for the Socially Anxious: Moderating Role of Drinking Context on Alcohol Outcome Expectancies

Background: Moderating effects of alcohol outcome expectancies (AOE) on the social anxiety (SA)-alcohol misuse relationship are mixed. This may be explained by differential relationships between SA and context-specific AOE. Gender may further moderate these associations, as it influences SA, AOE, and drinking behaviors. Objectives: To examine the moderating role of drinking context (i.e. convivial, negative coping, or personal-intimate) and gender on the relationships between SA and three AOE (i.e. tension reduction, sociability, and sexuality). Methods: Participants (n = 436, M_age=19.32, 72% female, 85.8% White) were 218 undergraduates with elevated SA (high SA group) and a gender-matched low SA group (n = 218) drawn from a larger undergraduate sample (N = 1,015). Participants completed three versions of an AOE measure, differing by drinking context considered. Results: A significant SA group x context x gender interaction was found for tension reduction AOE; compared to men, women in the low SA group reported greater tension reduction AOE in negative coping contexts. Significant SA group and context main effects suggest that sociability and sexuality AOE are endorsed more in the high (vs. low) SA group, and in convivial and personal-intimate compared to negative coping contexts. Conclusions/Importance: Tension reduction AOE vary depending on the drinking context, SA, and gender. Assessment of AOE in specific drinking contexts may help to identify which individuals may be at greatest risk for alcohol misuse and help inform treatment of SA-related problem drinking.
