Objectives: The objective of the study was to obtain pilot data comparing hypnotherapy and behavioral therapy (hypnotherapy) to behavioral therapy alone (behavioral therapy) in overactive bladder (OAB) treatment.
Methods: Women with OAB were randomized to hypnotherapy or behavioral therapy treatments. Patient Global Impression of Improvement (PGI-I), the OAB-q Short Form (OAB-q SF) questionnaire, and voiding diaries were recorded, and within- and between-group differences were compared.
Results: Twenty women enrolled in and completed the study. Both hypnotherapy and behavioral therapy groups improved their mean number of voids (P = 0.005, P = 0.01, respectively) and their OAB-q SF distress scores (P = 0.002, P = 0.03). The hypnotherapy group had significant improvement in quality-of-life scores (P < 0.001), whereas the behavioral group did not (P = 0.05). Between-group comparisons showed that the hypnotherapy group had superior PGI-I scores compared with the behavioral group (P < 0.009). The hypnotherapy group trended toward greater improvement in OAB-q quality-of-life scores compared with the behavioral therapy group (67% vs 42% improvement), although this did not reach statistical significance (P = 0.07). Number of voids and OAB-q SF distress scores improved in both groups with no difference between groups.
Conclusions: Both groups improved with treatment. Hypnotherapy resulted in superior PGI-I scores compared with behavioral therapy. Voiding and OAB-q SF results trended toward greater improvement with hypnotherapy. As a pilot study, recruitment was underpowered to find statistical differences between groups' voids and OAB scores. These findings support the need for an expanded trial that could likely show hypnotherapy to be superior in OAB treatment.
