Characteristics of dropouts and completers from hypnobehavioral treatment for bulimia nervosa

This study compares demographic and psychological characteristics of a group of dropouts and completers from a hypnobehavioral treatment program for bulimia nervosa. Prior to treatment, 30 dropouts and 30 completers were assessed on the following questionnaires and scales: the Eating Disorders Inventory, the Zung Depression Scale, the General Health Questionnaire, the Eysenck Personality Inventory, the Stanford Hypnotic Clinical Scale, and five Visual Analogue Scales and Expectancy Scales. Results of ANOVA and chi-square analyses showed no significant differences between dropouts and completers on any of the demographic variables or psychological measures or scales. The results suggest that neither demographic nor psychological characteristics play a role in identifying dropouts from bulimia nervosa treatment.
