Solitary drinking, social isolation, and escape drinking motives as predictors of high quantity drinking, among Anglo, African American and Mexican American males.
This paper addresses the phenomenon of 'solitary drinking', considering whether Anglo, African American and Mexican American male regular drinkers differ in the propensity to drink in solitary contexts and whether such differences may help to explain observed ethnic variation in patterns of heavy drinking. Further, the paper considers whether apparent relationships between solitary drinking and drinking patterns are explained by individual personality characteristics such as social isolation and/or by endorsement of 'escape drinking' motives. Data were analysed from a random community sample of 481 adult male regular drinkers in San Antonio, Texas, USA. Contingency table and logistic regression analyses indicated that initially observed ethnic differences in high quantity and high maximum drinking were largely eliminated by controls for education, escape motives and solitary drinking. Ethnic variation in the role of solitary drinking was suggested as well, with solitary drinking more strongly related to high quantity consumption, in particular, among African Americans than among Mexican Americans. The nature of the observed interactions suggests that fundamental differences between Anglos and African Americans in the roles of solitary drinking and escape drinking motives may underlie seemingly similar frequent, lower quantity drinking patterns in these groups that appear more frequently than among Mexican American males.
