Abstract

Objective: To compare the efficacy of the compuLsive Exercise Activity theraPy (LEAP) programme integrated with manualised cognitive behavioural therapy for anorexia nervosa (CBT-AN) compared to CBT-AN alone.
Method: Seventy-eight adults were randomised to CBT-AN, delivered with or without 8 embedded sessions of LEAP, for a total of 34 individual outpatient sessions. Participants were assessed at baseline, the end of the first phase of CBT-AN (which included LEAP), mid-therapy, end of therapy, and at 3 and 6-months follow-up. Linear mixed effects modelling was used for comparing trajectories over time by group in primary outcomes of pathological exercise cognitions and secondary outcomes of exercise frequency, BMI, eating disorder (ED) symptoms, AN stage of change, anxiety/depression, and health related quality of life.
Results: There were significant improvements over time in all outcomes. There were no significant differences between treatment groups in primary outcome measures. Fidelity and end-of- treatment participant satisfaction were satisfactory across both conditions.
Discussion: CBT-AN and LEAP added to CBT-AN resulted in improved attitudes and beliefs towards exercise and general improvements in BMI and eating disorder psychopathology in people with AN.
