    Abstract

    The study examined the validity of the transdiagnostic cognitive behavioural theory of eating disorders. The aim was to determine if the maintaining mechanisms of clinical perfectionism, core low self esteem, mood intolerance and interpersonal difficulties have a direct impact on dietary restraint or an indirect impact via eating, shape and weight concerns. The model was tested in a community sample of 224 females recruited via the internet. The structural equation model provided a good fit for the data. The relationship between maintaining mechanisms and dietary restraint was due to maintaining mechanisms impacting indirectly on dietary restraint via eating disorder psychopathology. The results lend support for the validity of the transdiagnostic model of eating disorders as the maintaining mechanisms lead to restraint via the core psychopathology of eating concerns, weight concerns and shape concerns. The findings suggest the four maintaining mechanisms alone are not enough to lead to dietary restraint, the core psychopathology of eating disorders needs to be present, which supports the predictions of the theory. These results help establish the validity of the transdiagnostic cognitive behavioural theory of eating disorders.
