Enhancement motives moderate the relationship between high-arousal positive moods and drinking quantity: Evidence from a 22-day experience sampling study

Individuals who consume alcohol may be distinguished by their drinking motives. Enhancement motives involve drinking to enhance positive moods. Research on the moderating effect of enhancement motives on the within-person relation between daily positive mood and drinking has not differentiated between high- (e.g. hyper) and low-arousal (e.g. cheerful) positive moods. The present study addressed this limitation.We hypothesized that enhancement motives would positively moderate the relationship between mid-afternoon high-arousal positive mood and evening drinking.
