AbstractFifty‐six patients with anorexia nervosa (19 restrictive type, 37 purging/bulimic type) and 32 patients with bulimia nervosa, purging type, filled in questionnaires at admission to an eating disorder unit, again at discharge and 6 months later. Among these questionnaires was the UCL, the Utrecht Coping List, a Dutch questionnaire on coping styles. To determine the association between changes in coping styles and changes in eating symptomatology and psychological functioning during treatment, correlations were calculated. Multiple regression analysis was used to assess the portion of the variance of the measurements at follow‐up that could be predicted by the coping styles at the end of treatment. Patients reported significant changes in coping styles in a favourable direction during treatment. Compared with normal controls, their coping styles at the end of the treatment were still more avoiding, more passive and more palliative reacting. They also made more use of reassuring thoughts, and less of active tackling and seeking of social support. The status of the patients 6 months after discharge was very well predicted by their status at discharge. After multiple regression analysis we found for both anorectic and bulimic patients that if they, at the end of the treatment made more use of the coping style reassuring thoughts, this would contribute to the prediction of a better status at follow‐up. Bulimic patients that at the end of the treatment made less use of the coping style palliative reacting, had a better status at follow‐up.
