Research suggests that self-control, affective lability, and negative urgency are associated with deliberate self-harm, problematic alcohol consumption, and eating problems. Few studies have fully examined how negative urgency might uniquely explain the effects of self-control and affective lability on these outcomes, as compared to other impulsivity-related traits. This was the goal of the current study. Of an initial group of 734 undergraduate students, 29 % indicated a history of deliberate self-harm. These 215 individuals were randomly matched with a group of non-self-harmers (total N = 430; mean age = 22.36, SD = 6.59; 76.2 % female). Self-harmers showed higher rates of alcohol use (F(2, 186) = 5.48, p < .001) and eating problems (F(2, 186) = 7.74, p < .001). In a structural equation model, negative urgency was significantly associated with self-harming frequency (¦Â = 3.81, p < .001), variety of self-harm methods (¦Â = 5.79, p < .001), the number of years of self-harming (¦Â = 2.75, p < .001), problematic alcohol use (¦Â = 1.80, p < .05), and eating problems (¦Â = 3.99, p < .001). Negative urgency was positively associated with affective lability (¦Â = 7.71, p < .001) and negatively associated with self-control (¦Â = ? 13.59, p < .001). Negative urgency is the only impulsivity-related trait that is a common risk factor associated with increased self-harm, problematic alcohol use, and eating problems.
