111. Momentary Impulsivity, Affect and Stress: Exploring the Urgency Cascade
Impulsivity has been conceptualized in the psychological literature in many different ways. Urgency, or rash action taken in response to strong negative or positive affect (Cyders, et al., 2007), captures the elements of impulsivity associated with higher levels of Neuroticism in the Five-Factor Model (FFM; Costa & McCrae, 1990). We aim to extend a within-person daily cascade model of positive and negative urgency (in individuals with personality disorders; Sharpe, Simms, & Wright, In Preparation) to the momentary level in a community sample. Using multilevel structural equation modeling, we examine within- and between-person predictors of momentary impulsivity, with a particular focus on testing a cascade model of affect and momentary stress in a 10-day ambulatory assessment study of 261 non-undergraduate community members. We model a cascade from stress to impulsivity through both positive and negative affect at the momentary level by regressing momentary impulsivity on the severity of concurrent stress, positive affect, and negative affect. At level 2 we include trait impulsivity as measured by Impulsivity facet scores at baseline on the Personality Inventory for DSM-5 (PID-5; American Psychiatric Association, 2013) as a between-person predictor.
