TY - JOUR PY - 2005// TI - Characteristics of impulsive behavior among eating disorder patients JO - Journal of the Osaka City Medical Center A1 - Wada, A.

These bulimic patients with "multi-impulsivity" show several interchangable types of impulsive behaviors such as suicide attempt, self-mutilation, shoplifting, alcohol/drug problems and sexual promiscuity. This study investigated the relationships among impulsivity and various impulsive behaviors and eating disorders using a standardized self-report questionnaire, the Barratt Impulsiveness Scale version 11 (BIS-11) which consisted of 3 subscale such as Attentional impulsiveness, Motor impulsiveness, Non-planning impulsiveness. [Methods] Subjects encountered between 1999 and 2001 consisted of 64 patients with anorexia nervosa restricting type (AN-R), 48 patients with anorexia nervosa binge eating/purging type (AN-BP), 93 patients with bulimia nervosa (BN) and 93 control subjects. All were asked to fill out the BIS-11, Impulsive Behavior Questionnaire (IBP) which assessed the impulsive behaviors and Eating Disorder Inventory (EDI) on the first visit in outpatient settings. [Results] The BN patients had significantly higher Attentional, Motor Impulsiveness score and BIS total score than the AN-R and control groups. The BN patients had significantly higher rate of a history of suicide attempt, self-mutilation, repeated shoplifting and sexual promiscuity than the control groups. In BN patients (N=93), Motor and BIS total score were significantly higher in patients with a history of suicide attempt, repeated shoplifting and sexual promiscuity. However, BN patients with a history of self-mutilation did not show any significant difference in Motor and BIS total score, but did show a significantly lower Non-planning impulsive BIS score than those without such a history. [Conclusions] These result suggest that BN patients had high impulsivity and some of them showed multi-impulsivity. Among impulsive behaviors, Self-mutilation showed a close relationship with bulimia nervosa and its character of impulsivity differs from those of other impulsive behaviors.
