Effectiveness of group and self-help cognitive behavior therapy in reducing problematic menopausal hot flushes and night sweats (MENOS 2)

Abstract

The aim of this study was to examine the effectiveness of group cognitive behavioral therapy (CBT) and guided self-help CBT in reducing hot flush and night sweat (HF/NS) problem rating at 6 and 26 weeks after randomization. This was a randomized control trial of 140 women having 10 or more problematic HF/NS a week for at least a month. The primary outcome was HF/NS problem rating (1-10) at 6 weeks after randomization. Secondary outcomes were physiologically measured HF/NS at 6 weeks; HF/NS problem rating at 6 weeks; and frequency, mood (Women's Health Questionnaire), and health-related quality of life (General Health Survey Short Form-36) at 6 and 26 weeks. Intention-to-treat analysis was used, and between-group differences were estimated using linear mixed models. Baseline mean (SD) HF/NS weekly frequency was 63.15 (49.24), and problem rating was 5.87 (2.28). Group and self-help CBT both significantly reduced HF/NS problem rating at 6 weeks-group CBT versus no treatment control (NTC; adjusted mean difference, 2.12; 95% CI, 1.36-2.88; P < 0.001) and self-help CBT versus NTC (adjusted mean difference, 2.08; 95% CI, 1.29-2.86; P < 0.001)-and at 26 weeks-group CBT versus NTC (adjusted mean difference, 1.33; 95% CI, 0.54-2.13; P = 0.001) and self-help CBT versus NTC (adjusted mean difference, 1.19; 95% CI, 0.36-2.02; P = 0.005). Group and self-help CBT significantly reduced night sweat frequency at 6 and 26 weeks. There were improvements in mood and quality of life at 6 weeks and improved emotional and physical functioning for group CBT at 26 weeks. These results suggest that CBT delivered in group or self-help format is an effective treatment option for women during the menopause transition and postmenopause with problematic HF/NS.
