Lifetime history of cigarette smoking associated with aggression and impulsivity in both healthy and personality disordered volunteers.
Cigarette smoking has been associated with several personality and behavioral traits including impulsivity and aggression, primarily in adolescents and/or pregnant women. In this study, the authors tested the hypothesis that history of cigarette smoking is also associated with dimensional measures of aggression and impulsivity in adult subjects. Subjects were 179 personality disordered (PD), and healthy volunteer control (HV), subjects in whom history of cigarette smoking and measures of both aggression and impulsivity were collected. Scores on measures of both aggression and impulsivity were elevated as a function of personality disorder status and history of cigarette smoking status; no interaction between these two factors were noted on these measures. Including socio-economic status and global psychosocial functioning in the model eliminated the difference associated with diagnostic grouping and impulsivity but not the difference in aggression associated with lifetime history of smoking. These data suggest that lifetime history of cigarette smoking is associated with elevations in life history of aggression regardless of the presence of psychiatric disorder in nontreatment seeking individuals.
