We used an experience sampling design to examine the within–person, within–day associations among interpersonal stress, negative affect, and alcohol use, and how these associations varied as a function of alcohol–outcome expectancies (AOEs), avoidance coping style, sex, and neuroticism. Ninety–eight community adult drinkers who wanted to reduce their alcohol consumption (49 women) reported for 21 days on their interpersonal stress and affect (three times per day), and alcohol use (as it occurred) using hand–held computers. Several individual difference factors interacted with daytime interpersonal stress and afternoon negative affect in predicting nighttime alcohol use, with individuals high in careless unconcern AOEs or low in impairment AOEs demonstrating stronger positive associations between daytime stress and negative affect and nighttime drinking. Daytime drinking and individual difference factors also interacted in predicting nighttime interpersonal stress, with individuals high in careless unconcern AOEs or those low in impairment AOEs or avoidance coping style demonstrating the strongest positive associations between daytime drinking and nighttime stress. The interactive effects in predicting drinking outcomes were generally limited to days on which some interpersonal stress occurred.
