What Triggers Abnormal Eating in Bulimic and Nonbulimic Women?; The Role of Dissociative Experiences, Negative Affect, and Psychopathology

Dissociative experiences and abnormal eating were examined in 92 non-eating-disordered women and 61 age-matched bulimic women. In the nonclinical sample of women, dissociative experiences were associated with abnormal eating attitudes and behavior, even after controlling for other forms of psychopathology; furthermore, dissociation mediated the relationships between abnormal eating and sexual abuse, abnormal eating and emotional distress, and abnormal eating and impulsivity Analyses using both bulimic women and occasional binge eaters among the controls showed that a combination of reported negative affect and dissociative experiences preceding a binge was associated with the highest levels of abnormal eating. Finally, in both bulimic women and occasional binge eaters, feelings of panic appeared to decrease as a binge episode progressed, whereas, in bulimic women only, dissociative experiences appeared to increase during binge eating. The implications for the role of dissociation in combination with emotional distress in triggering and reinforcing abnormal eating in women are discussed.
