In the literature on alcohol use and aging, drinking has often been conceptualized as a means of coping with negative feelings, such as stress, yet much of the literature on older adults and drinking has utilized cross-sectional or other data ill-suited for exploring dynamic processes. Experience sampling methods have the ability to measure and analyze dynamic processes in real time, such as relations between alcohol use and mood states. Nonetheless, these approaches are intensive and may burden respondents. Therefore, this study evaluated the feasibility, acceptability, and validity of a modified daily diary to measure alcohol use and explored alternate methods of collecting diary data. Findings suggest that a modified diary was acceptable and not burdensome. Respondents were reluctant to consider technology (e.g., cellphone)-based means of data collection. Measures of alcohol use showed little within-person variation suggesting that for those who drink at all, drinking is a daily habit.
