The proposed F32 aims to conduct a secondary analysis of time-intensive daily data (MPIs: Lee/Patrick; R01AA025037) to elucidate the roles of affect and affective dynamics on simultaneous alcohol and marijuana (SAM) use outcomes among a sample of high-risk adults (N = 409). We will test whether theoretically-relevant affective dynamic processes (affective instability, negative emotion differentiation): (1) are more useful for predicting SAM use and alcohol use than mean level of affect (within- and between-subjects); (2) prospectively predict changes in SAM use and use-related problems over time; and (3) can distinguish SAM use from single substance use patterns, which has direct implications for the personalization and precision of prevention and intervention efforts.
