Impulsivity is an important risk factor of severe course of alcohol dependence. However, the significance of environmental determinants of impulsivity has been underestimated. The aim of the study was to identify psychosocial factors increasing the level of impulsivity in alcoholics. Levels of impulsivity were measured in 304 alcohol-dependent patients. Stop-signal task was used to assess behavioral impulsivity, and Barratt Impulsiveness Scale to measure global and cognitive impulsivity. Correlations between impulsivity and psychosocial variables were examined. A significant association between level of impulsivity and severity of psychopathological symptoms were observed. Patients who reported childhood sexual or physical abuse, lower social support, more severe course of alcohol dependence were more impulsive, especially in cognitive domain. When entered into a linear regression analysis model, severity of alcohol dependence, psychopathology and childhood physical abuse remained significant. These results suggest that psychosocial variables are important factors associated with high levels of impulsivity in alcohol-dependent patients.
