    Author: Pryor T, Wiederman MW, McGilley B.
    Journal: Int J Eat Disord; 1996 Jul; 20(1):13-8. PubMed ID: 8807348.
    Abstract:
    OBJECTIVE: The results of the scant research on laxative abuse among women with eating disorders suggest that laxative abuse is a diagnostic indicator of greater psychopathology. We further investigated the relationship of history of laxative abuse to eating and related attitudes, impulsivity, and personality pathology. METHOD: Women assessed in an outpatient clinical setting and diagnosed with anorexia nervosa, binge-eating/purging type (n = 51) or bulimia nervosa, purging type (n = 280) completed measures of laxative abuse, eating and related attitudes, and personality psychopathology at intake. RESULTS: More than one-half of both groups had abused laxatives at some point. History of laxative abuse was unrelated to eating disorder diagnostic category, current age or body weight, history of stealing, self-induced injury, having attempted suicide, interpersonal distrust, maturity fears, or compulsive or dependent personality features. Compared to nonabusers, laxative abusers demonstrated more perfectionism and avoidant personality features. Significant statistical interactions among variables revealed that bulimia nervosa patients who had abused laxatives exhibited the most pathological scores on scales measuring drive for thinness, body dissatisfaction, ineffectiveness, lack of interoceptive awareness, and passive-aggressive and borderline personality features. Anorexia nervosa patients who had abused laxatives had the highest scores on the histrionic scale. DISCUSSION: Results are discussed with regard to past research and clinical implications. We propose that laxative abuse among eating disordered women may serve different functions depending on diagnosis and underlying personality dynamics.
