According to a research study, individuals’ sense of autonomy and motivation can strongly influence their drinking behaviours and the consequences they experience. The study, published in the peer-reviewed journal Alcohol: Clinical & Experimental Research, included 630 adult participants aged 18-57 years to evaluate their self-determined drinking motives. Participants were evaluated on five drinking motivations: intrinsic (for enjoyment), identified (for personal benefits), positive introjected (for confidence), external (due to social pressure), and amotivational (without clear reasons).
Participants were categorized into four drinking profiles: “aimless drinkers” (12%) with low intrinsic motivation and unclear motives, “flexible drinkers” (42%) motivated by multiple factors, “externally controlled drinkers” (28%) driven by social pressure and confidence needs, and “pleasure drinkers” (18%) motivated by intrinsic enjoyment, often older and exhibiting greater internal control.
Moreover, the four drinking profiles also varied in frequency, intensity, and outcomes. It was found that aimless drinkers tended to engage in riskier drinking with worse consequences, while externally controlled drinkers drank more often and intensely, experiencing more negative effects. In contrast, pleasure drinkers consumed less alcohol and reported the most positive experiences. These findings highlight the usefulness of self-determination theory in understanding drinking motivations and support harm reduction strategies aimed at high-risk groups.
“Older individuals were more likely to drink due to intrinsic enjoyment, which may reflect a shift toward greater autonomy over alcohol consumption with increasing age,” concluded the authors. “Drinking primarily for enjoyment also facilitated more positive drinking outcomes. Future research should investigate whether motivational profiles of behavioral regulations for drinking predict long-term trajectories of alcohol consumption and alcohol-related risks.” In addition, the authors also suggested that gaining a better understanding of such motivations could help guide individuals who drink dangerously, such as young adults who binge drink, toward safer, lower-risk drinking behaviours.
