Abstract

Purpose To evaluate the efficacy of a 7-session manualised group intervention for Compulsive Exercise (NEAT) as an adjuvant to inpatient treatment for adolescents with Anorexia Nervosa (AN). Methods Adolescents aged 12–17 consented to the study (N = 75). Using a randomised control design, they were allocated to the NEAT group with treatment as usual (NEAT + TAU) (N = 43), or to treatment as usual alone (TAU) (N = 32). Self-report measures of compulsive exercise and eating disorder psychopathology were administered at two timepoints to assess the efficacy of the intervention. Results 51 participants completed the study (NEAT + TAU N = 27; TAU N = 24). Both groups saw a significant decrease in compulsive exercise and eating disorder psychopathology between timepoints. There were no significant differences between treatment groups on the outcome measures. Conclusions Intensive, multidisciplinary TAU, and NEAT group added to TAU were effective at reducing compulsive exercise and eating disorder symptoms. Clinical opinion and recommendations for further study are discussed. Treatment manual is made available below. Level of evidence: Level I Evidence obtained from: at least one properly designed randomised controlled trials; systematic reviews and meta-analyses; experimental studies.
