This combined pilot feasibility study and randomized controlled trial will evaluate specific factors crucial to the success of a large trial to evaluate the effect of Mindfulness-Based Stress Reduction on urinary urge incontinence in older adult women. Moore (2011) recommended that the pilot study design parallel the future larger study, particularly when evaluating feasibility in the pilot study. The capacity for hypothesis testing, or establishing causal inference is limited in a pilot study due to insufficient power; however, the information from efficacy testing is vital in informing future larger scale clinical trials. This study will serve as a necessary step for the development of effectiveness trials of Mindfulness-Based Stress Reduction in treatment of urinary urge incontinence in older adult women by informing and guiding evaluation, implementation, and dissemination.
