Effects of social drinking context on subjective effects, affect, and next‐day appraisals in the natural environment

Abstract

AbstractBackgroundDrinking commonly occurs in social settings and may bolster social reinforcement. Laboratory studies suggest that subjective effects and mood are mechanisms through which the social context influences alcohol consumption. Ecological momentary assessment (EMA) may be useful for extending these findings to the natural environment. This pre‐registered secondary analysis of EMA data investigated the influence of the social environment on: (1) stimulating and sedating subjective effects of alcohol, (2) contentedness and negative affect, and (3) next‐day evaluations of the drinking occasion.MethodsNontreatment seeking adults reporting past‐month heavy drinking (N = 131; Mage = 28.09; 42% female) completed 7 days of EMA (in the morning, at random, and following drinking prompts), which included questions on their social context (drinking in the presence of known others or alone), contemporaneous stimulating and sedating effects, contentedness and negative affect, alcohol consumption, and next‐day evaluations of a prior day's drinking event (how satisfying/pleasant was drinking). We used multi‐level models in SAS 9.4 M7 software to examine relations among the variables.ResultsContemporaneous subjective effects (stimulating or sedating), negative affect, and contentedness did not significantly depend on the social context. For next‐day evaluations of pleasure/satisfaction from drinking, context effects were dependent on consumption totals. As the total number of standard drinks consumed increased, recollections of pleasure/satisfaction were higher when drinking had occurred with others, relative to alone. At lower consumption totals, next‐day evaluations did not appear to depend on social context.ConclusionsWhen reported contemporaneously, subjective effects and affect do not appear dependent upon the presence of known others. However, heavier drinking events, relative to lighter drinking events, are appraised more favorably the following day when occurring within social contexts.
