Although group therapy is often recommended for the treatment of bulim
ia nervosa, relatively little is known about predictors of short-term
outcome. This pilot study examined whether a standardized measure of r
eadiness for change might be related to changes in binge frequency. Si
xteen bulimic patients participated in short-term cognitive behavioral
group therapy for twelve weeks Each patient completed the Change Asse
ssment Scale prior to treatment along with a battery of symptom measur
es which were readministered at the conclusion of therapy. Bulimic pat
ients with positive outcome in binge frequency were at a higher stage
of readiness for change at pretreatment than were patients with negati
ve outcome. Results indicated that there may be methods of determining
who would be most likely to benefit from cognitive behavioral group t
herapy, and tentatively suggest that interventions may be more success
ful when readiness for change is taken into consideration.
