Shared Genetic Liability for Alcohol Consumption, Alcohol Problems, and Suicide Attempt Overlaps with the Genetic Basis of Multiple Dimensions of Impulsivity

We investigated whether shared liability for alcohol consumption and problems (ACP) and suicide attempt (SA) is genetically related to five dimensions of impulsivity. A common genetic factor for ACP and SA was most highly correlated with lack of premeditation, followed by positive urgency, lack of perseverance, sensation-seeking, and negative urgency.
