Long-Term Outcomes of Depression Treatment With Hypnotherapy or Cognitive Behavioral Therapy

Abstract

Abstract In a recent randomized controlled trial of mild to moderate depression, hypnotherapy (HT) was noninferior to cognitive behavioral therapy (CBT) after 6 months of outpatient treatment. In the present article, we extended the results in a secondary analysis and investigated how HT compares with CBT 1) during the course of the self-rated depressive symptoms throughout the 12-month follow-ups, 2) with regard to the rates of full remission, and 3) for the time to remission after treatment. Of the 152 randomized patients with current depression, 136 were available for the follow-up analyses. The course of self-rated depressive symptoms during follow-ups was analyzed with linear mixed-effects models. Time to a full remission, defined as eight consecutive weeks without depression, was compared between groups in a survival analysis. The self-reported depressive symptoms could be maintained on a low symptom level during the 12-month follow-up for both HT and CBT. Overall, both treatments achieved comparably high long-term remission rates of 73% after a median of 30 weeks. Outpatient psychotherapy with HT achieved good long-term results mostly comparable to CBT.
