This three-site randomized controlled trial compares the effectiveness and cost-effectiveness of a group-administered behavioral treatment program to no treatment. Women with stress, urgency, or mixed urinary incontinence will be recruited and screened centrally, evaluated clinically at each of three study sites, and random assigned to one of two treatment arms: 1. Group behavioral treatment or 2. No treatment. Group treatment modalities have the potential to reach a larger population of older women with urinary incontinence, not only in the traditional medical settings, but also in community settings. The investigators hypothesize that group behavioral treatment will be more effective than no treatment. The investigators hypothesize that the group treatment will be cost-effective compared to no treatment.
