A test of the high-risk model of threat perception applied to eating disorders Only 32\% of all patients with eating disorders who have had treatment will be in remission from eating disorders after 1 year. This study investigated the value of the High Risk Model of Threat Perception (HRMTP) as a predictor of treatment success among patients with eating disorders. The HRMTP has been used to predict vulnerability to somatic conditions such as migraine headaches, backaches, and autoimmune disorders, but this was the first study evaluating the HRMTP as a predictor of short-term treatment outcome in a residential program for eating disorder patients. The participants included 123 patients with DSM-IV diagnoses of anorexia nervosa, bulimia nervosa, eating disorders not otherwise specified, and binge eating disorder, aged 18 and older with a median age of 27.5. Upon admission, patients were administered the following tests to assess risk factors for the HRMTP: Tellegen Absorption Scale (TAS) to determine hypnotizability, the Marlowe-Crowne Social Desirability Scale to measure repression or self-deception, and the Eysenck Personality Inventory to measure negative affectivity. At admission and 4 weeks after admission, patients took the Minnesota Multiphasic Personality Inventory-2 (MMPI-2), the Eating Disorders Inventory-2 (EDI-2), and the Beck Depression Inventory (BDI) to measure pathology. All hypotheses were tested with a series of 2-way mixed design ANOVAs. The repeated measures variable was time of measurement (baseline vs. retesting after 4 weeks). The dependent variables were scores on the BDI, the 11 subscales of the EDI-2, and the 10 clinical scales of the MMPI-II. The hypotheses were not supported. Being at higher risk for the HRMTP did not predict successful outcomes in treatment. Possible explanations include no treatment control group, lack of a control group treated only with cognitive behavioral therapy, the low correlation of the TAS with hypnotizability (0.44) and the possibility that the integrative treatment program offered was so potent and efficacious that it reduced the significance of high and low risk factors. Future research utilizing an integrated neurobiopsychosocial model will produce greatly improved results in the treatment of people with eating disorders.
