Predicting premature termination of hospitalised treatment for anorexia nervosa: The roles of therapeutic alliance, motivation, and behaviour change

Objectives: This study aims to investigate treatment drop-out, and the associated roles of motivation, alliance, and behaviour change exhibited over the first four weeks of hospitalised treatment for anorexia. Methods: 90 participants meeting DSM-IV criteria for anorexia nervosa completed questionnaires at admission, and four weeks into treatment Weight data was collected over this same time period. At the end of treatment, participants were categorised into completer or premature termination groups. Results: The overall rate of premature termination was 57.8%. Those who prematurely terminated treatment demonstrated lower discharge BMI (p<.0005), and weight gain (p<.0005) than those who completed. Therapeutic alliance proved significantly different between outcome groups at admission (p=.004). Discussion: End-of-treatment outcomes for those who do not complete treatment are invariably poor. Therapeutic alliance appears to be a particularly important factor in this area. (C) 2013 Elsevier Ltd. All rights reserved.
