The Transdiagnostic Nature of Metacognitions in Women With Eating Disorders

There is emerging evidence for the important role of metacognitions in the presentation of eating disorders (EDs); however it is unclear to what extent these metacogntions are transdiagnostic. This study used a mixed methods convergent design to explore this question by triangulating both qualitative and quantitative data from 27 women, aged 18-55 years, with diagnoses of anorexia nervosa, bulimia nervosa, or eating disorders not otherwise specified. The results indicated that metacognitions in EDs may be transdiagnostic and may in part explain temporal migration between diagnoses and the degree of comorbidity associated with EDs.
