Anorexia Nervosa: Lessons from
a Follow-up Study
Helm Stierlin, MD,Ph.D., and Gunthard
Weber,
MD
In 1984 and 1987 we carried out follow-up studies on most of the anorexia
families we had been treating. The first time we included
31,
the second time 62
families. The findings from the first study have already been published (11).
With each study we had different aims in mind and employed different
methods. Before we focus on these, we would like to comment briefly on the
value and limits of outcome studies in general.
These studies provide information on the natural course of an illness or
disturbance and on the efficacy of therapeutic measures. Therefore, it should
not surprise us that there now exist over 50 studies, worldwide, which examine
the course of anorexia nervosa after various types of therapy. Recently Hsu (5)
gave a critical overview of such studies. When compared with other outcome
studies in the psychotherapeutic domain, studies of anorectics promise relatively
clear-cut results. They can measure not only "soft" psychosocial factors but also
"hard" data such as weight gain, menstruation, and observable changes in eating
behaviors. However, even here, a number of methodological problems remain
that have been insufficiently addressed by existing studies. For example, Hsu (5)
mentions several serious methodological failings of outcome studies in anorexia
nervosa. He mentions in particular:
• lack of clinical data and inadequate diagnostic criteria;
• lack of adequate description of treatment;
• inadequate followup (e.g., short duration of follow-up, a high failure-to-
trace rate, indirect methods of evaluation, poorly defined outcome criteria,
failure to employ multiple outcome measures).
We may add to this list another failing: The health of the other family
members and the development of the whole family are not given enough
attention. Our experience as family therapists has taught us that frequently
