Acting impulsively when "upset": Examining associations among negative urgency, undifferentiated negative affect, and impulsivity using momentary and experimental methods.

Abstract

Negative urgency is a personality pathway toward impulsive behavior that increases risk for transdiagnostic psychopathology. Limited research supports the core tenant of urgency theory, that is, that individuals with high trait negative urgency act more impulsive when experiencing increased negative emotion. We hypothesized that it may not be negative emotion intensity, but difficulty in differentiating among negative emotions, that prompts impulsive behavior among individuals with elevated negative urgency. We tested this hypothesis in 200 undergraduates using both ecological momentary assessment (measured momentary undifferentiated negative affect and impulsivity) and experimental methods (manipulated emotion differentiation and measured behavioral impulsivity). Momentary undifferentiated negative affect predicted impulsivity in the specific domains of work/school and exercise, but interactions between momentary undifferentiated negative affect and negative urgency were not supported. Manipulated emotion differentiation did not impact behavioral impulsivity regardless of negative urgency scores. Inconsistent with theory, the impulsive behavior of individuals with negative urgency may not be conditional on elevated or undifferentiated negative affect.
