This paper provides a brief overview of the diagnosis, prevalence, med
ical and psychosocial side effects, and assessment of the dieting diso
rder, bulimia nervosa. An update is given of the psychological treatme
nt approaches: cognitive behavioural, behavioural, hypnobehavioural, p
sychodynamic, psychoeducation, family therapy, and nutritional managem
ent. Findings from uncontrolled and controlled clinical trials are sum
marised, and we discuss some guidelines for clinical and research prac
tice. Suggestions for further applied research include: developing an
internationally agreed set of instruments to determine outcome, invest
igating the mode of action of various treatments, focusing on newer in
terventions, exploring the durability of shorter treatments, evaluatin
g the effectiveness of less intense forms of treatment compared to mor
e intense forms, determining which treatments match or suit certain pa
tients, and exploring techniques to decrease attrition in treatment ou
tcome research.
