Delusional intensity as a prognostic indicator among individuals with severe to extreme anorexia nervosa hospitalized at an acute medical stabilization program

Abstract

Although the delusional intensity of eating disorder beliefs did not significantly improve over this relatively brief interval, delusional intensity may be associated with the severity of central eating disorder attitudes and behaviors. Delusional intensity may therefore be a negative prognostic indicator, possibly warranting further treatment. Future research should examine changes in delusional intensity over longer intervals and test whether specifically targeting delusional beliefs improves treatment outcomes among individuals with AN.
