An interactive model of bulimic symptom development, first suggested by Vohs et al. (1999), was tested in adult women (mean age = 45.19). The following hypothesis was examined in a longitudinal design over 2.5 years: Women high in perfectionism, low in self-esteem, and who perceive themselves as overweight would be the most likely to experience an increase in bulimic symptoms. Results supported the model with regard to maintenance and exacerbation, but not onset, of bulimic symptoms. Furthermore, the interactive model was tested to see if it showed specificity to bulimic, versus depressive or anxious, symptoms. Some support for the model's specificity to bulimic symptoms was observed; however, the increase of anxious symptoms was also observed. Clinical and theoretical implications are discussed.
