A preliminary investigation of impulsivity in generalized anxiety disorder
چکیده انگلیسی

Few studies have examined the association between impulsivity and generalized anxiety disorder (GAD). This study examined whether individuals with probable GAD display impulsivity in a particular way, and the extent to which impulsivity uniquely predicts GAD severity and GAD status, over and above intolerance of uncertainty (IU), a key cognitive factor in GAD. Individuals with (n = 63) and without (n = 77) probable GAD completed self-report measures of impulsivity and IU. Results revealed that elevations in the severity of GAD symptoms and in IU were associated with impulsive actions in the face of negative affect (i.e., negative urgency), but also greater premeditation and lower “functional” impulsivity (i.e., the ability to take quick action when it is advantageous to do so). Impulsivity led to an increment in the prediction of GAD symptoms and GAD status, over and above IU. Negative urgency and lower functional impulsivity were significant unique predictors of GAD severity or GAD status. The findings highlight a need to consider impulsivity in theories that implicate intolerance of negative affect and uncertainty in excessive and uncontrollable worry.


► This study examined the association of impulsivity to GAD status and GAD severity.
► Impulsivity predicted GAD over and above intolerance of uncertainty (IU).
► Negative urgency, lower functional impulsivity and IU uniquely predicted GAD.
► Findings are discussed in relation to existing psychological theories of GAD.
