Multidimensional Impulsivity and Suicidal Behaviour: A Partial Test of the Integrated Motivational-Volitional (IMV) Model of Suicide.

Urgency, regardless of positive or negative valence, is important for understanding differences in lifetime suicidal behavior. Sensation-seeking may play a protective role for direct suicidal behavior. Negative urgency may be the most prominent aspect of impulsivity when considered as an IMV moderator. Findings are contextualized with respect to impulsivity and IMV frameworks. Clinical implications involve accounting for negative urgency in suicide risk assessment and intervention.
