A laboratory-based investigation of relations among video lottery terminal (VLT) play, negative mood, and alcohol consumption in regular VLT players

Thirty regular video lottery terminal (VLT) players were randomly assigned to 90 min of VLT play or a control activity (viewing a movie) to examine the impact of VLT play on alcohol use. Ratings of dysphoric mood were taken at baseline, midactivity, and postactivity. Alcoholic and nonalcoholic control beverages were available throughout. As hypothesized, those in the VLT condition were more likely to consume alcoholic than nonalcoholic control beverages (i.e., 73% drank alcohol and 20% drank control beverages), whereas no such preference for alcohol was observed in the movie control condition (i.e., 40% drank alcohol and 47% drank control beverages). Consistent with predictions derived from Steele and Josephs' [J. Abnorm. Psychol. 97 (1988) 196; Am. Psychol. 45 (1990) 921.] attention allocation model, VLT condition participants who drank alcohol showed increases in dysphoric effect over the course of testing. No such changes in negative mood were observed in VLT participants who did not consume alcohol or in movie control participants regardless of whether they drank alcohol. An observed temporal pattern of greater drinking during the early phase of VLT play indicated that the relation between alcohol use and dysphoric affect among VLT condition participants could not readily be explained by drinking to relieve dysphoria induced by VLT losses. Clinical and policy implications are discussed.
