A detailed comparison was made of two methods for assessing the features of eating disorders. An investigator-based interview was compared with a self-report questionnaire based directly on that interview. A number of important discrepancies emerged. Although the two measures performed similarly with respect to the assessment of unambiguous behavioral(More)
Randomized clinical trials (RCTs) not only are the gold standard for evaluating the efficacy and effectiveness of psychiatric treatments but also can be valuable in revealing moderators and mediators of therapeutic change. Conceptually, moderators identify on whom and under what circumstances treatments have different effects. Mediators identify why and how(More)
This paper is concerned with the psychopathological processes that account for the persistence of severe eating disorders. Two separate but interrelated lines of argument are developed. One is that the leading evidence-based theory of the maintenance of eating disorders, the cognitive behavioural theory of bulimia nervosa, should be extended in its focus to(More)
BACKGROUND Many apparently disparate risk factors have been implicated as causes of eating disorders. This study was designed to test the hypothesis that 2 broad classes of risk factors exist for bulimia nervosa: those that increase the risk for development of a psychiatric disorder in general and those that increase the risk of dieting. It was predicted(More)
A consortium of researchers, advocates and clinicians announces here research priorities for improving the lives of people with mental illness around the world, and calls for urgent action and investment. dependence and other mental, neurological and substance-use (MNS) disorders constitute 13% of the global burden of disease (Table 1), surpassing both(More)
BACKGROUND Little is known about the longer-term outcome of bulimia nervosa and the distal effects of treatment. METHODS Prospective follow-up of subjects from two randomized controlled trials, involving a comparison of cognitive behavior therapy, behavior therapy, and focal interpersonal therapy. RESULTS Ninety percent (89/99) underwent reassessment by(More)
The specificity and magnitude of the effects of cognitive behavior therapy in the treatment of bulimia nervosa were evaluated. Seventy-five patients who met strict diagnostic criteria were treated with either cognitive behavior therapy, a simplified behavioral version of this treatment, or interpersonal psychotherapy. Assessment was by interview and(More)
The "Not Otherwise Specified" (NOS) category within DSM-IV is designed for disorders of clinical severity that are not specified within broad diagnostic classes. "NOS" diagnoses are intended to be residual categories and they tend to be neglected by researchers. This can be inappropriate. The problems associated with certain NOS diagnoses are well(More)

This paper describes the development and performance of an investigator-based interview (the PBE) for the detailed assessment of the behaviour of subjects over the preceding four weeks. The interview is designed to be administered to carers. A test-retest(More)

METHODS A community-based, case-control design was used to compare 52 women with binge eating disorder, 104 without an eating disorder, 102 with other psychiatric disorders, and 102 with bulimia nervosa. RESULTS The(More)
