30-60% of patients with severe HA have a comorbid personality disorder. Both patients with severe HA with or without comorbid PD show reduction in health anxiety from short term group CBT, but patients with comorbid personality disorder show a significantly lower cure-rate, than patients without comorbid personality disorder. Patients with severe health anxiety and comorbid PD (or other comorbid mental disorders) afterwards therefore need long term psychotherapeutic treatment to be cured. This hypotheses will be examined at 24 month follow-up, where a part of the patients after group CBT also have received long term psychotherapy for their PD.
