The moderating role of social support on the relationship between impulsivity and suicide risk

Background: Suicide is the second leading cause of death among college students. There has been considerable research into risk factors for suicide, such as impulsivity, but considerably less research on protective factors. Aims: The present study examines the role that social support plays in the relationship between impulsivity and suicide risk. Methods: Participants were 169 undergraduates who completed self-report measures of impulsivity and social support. Suicide risk was assessed using an interview measure. Results: Social support moderates the relationship between impulsivity and suicide risk, such that those who are highly impulsive are less likely to be at risk for suicide if they also have high levels of social support. Conclusions: Social support can be a useful buffer to suicide risk for at-risk individuals who are highly impulsive.
