Objective: This study examined outcome differences of 109 obese subjects, who participated in a 10-week cognitive-behavioral inpatient treatment followed by either a weight maintenance program or a follow-up period without professional support.
Methods: Self-rated weight loss, eating behaviors, and general psychopathology were assessed several months before treatment, when subjects were admitted, at discharge, and at the 6-, 12-, and 18-month follow-ups. Structured interviews for mental disorders and eating pathology were conducted additionally.
Results: The mean weight of the sample at baseline was 127 kg. Weight loss of the total sample amounted to 8.0 kg (6.3%) and was completely maintained during the follow-up period. Significant reductions of eating and general psychopathology were observed at the 18-month follow-up. The outcome in the maintenance condition did not significantly differ from the outcome in the control condition.
Conclusions: Weight regain after obesity treatment is not inevitable, but continuous patient-therapist contacts do not distinctly improve treatment effects.
