--- - |2+ Abstract Objective This study examined whether three facets of impulsivity previously shown to be associated with suicidal ideation and attempts (negative urgency, lack of premeditation, and lack of perseverance) help to account for the established association between problem solving deficits and suicidal ideation. Method Emerging adult college student drinkers with a history of at least passive suicidal ideation (N = 387) completed measures of problem solving, impulsivity, and suicidal ideation. A path analysis was conducted to examine the mediating role of impulsivity variables in the association between problem solving (rational problem solving, positive and negative problem orientation, and avoidance style) and suicidal ideation. Results Direct and indirect associations through impulsivity, particularly negative urgency, were found between problem solving and severity of suicidal ideation. Conclusions Interventions aimed at teaching problem solving skills, as well as self‐efficacy and optimism for solving life problems, may help to reduce impulsivity and suicidal ideation. - Journal of Clinical Psychology, Volume 74, Issue 9, Page 1626-1640, September 2018.
