A daily level analysis of drinking to cope motivation and interpersonal stress
Addictive behaviors(2021)
Abstract
Interpersonal stress is a commonly reported drinking-related problem and evidence indicates that it is associated with drinking to cope (DTC) motivation. The preponderance of evidence for DTC motivation as a risk factor for increased interpersonal stress, however, comes mainly from studies examining between-person associations. Findings suggest that individuals who commonly report drinking to cope with stress show higher average levels of drinking-related interpersonal problems. To better understand the dynamic processes linking DTC motivation with interpersonal stress, we used a micro-longitudinal design to examine whether nighttime drinking-episode specific levels of three subtypes of DTC motivation (DTC related to anxiety, depressive affect and anger) were associated with concurrent and next-day levels of interpersonal stress, controlling for drinking levels. Participants (N = 939) reported their drinking motives, drinking level, and drinking-related problems daily for 30 days during college and again approximately five years later (post-college). Results indicated that, controlling for drinking levels, DTC motivation associated with depressive affect and anger, but not anxiety, were positively associated with concurrent nighttime interpersonal stress. Only DTC related to anger was associated with higher levels of next-day interpersonal stress, controlling for previous night's stress. The only other motive to predict next-day interpersonal stress was conformity motivation. None of the effects of motives varied across study wave. Findings are discussed in terms of how DTC anger might exacerbate interpersonal problems via processes associated with alcohol myopia.
