Abstract:
The purpose of this study was to determine clinically significant change criteria and change trajectories for the Change in Eating Disorder Symptoms Scale (CHEDS). Participants included non-eating disordered (n=95) and eating disordered (n=58) samples. The clinical sample was undergoing enhanced cognitive-behavior therapy (CBT-E) for eating disorders. Reliable change indices (RCI), cutscores, and change trajectories were calculated. CHEDS total score RCI was 12 points while the cutscore between eating disordered and non-eating disordered groups was 65. Trajectory models for benchmarking were successfully derived based on initial scores. The change indices and trajectories permit session-by-session analyses and benchmarking of change. These empirically-calibrated indices of patient change and progress allow for empirically-guided treatment decision-making.
