The validation of patient-rated global assessments of treatment benefit, satisfaction, and willingness to continue--the BSW.

Objective: This study evaluated the validity of three single-item, patient-rated, interviewer-administered, global assessments of treatment benefit, satisfaction with treatment and willingness to continue treatment, collectively referred to as the BSW.

Methods: The BSW, micturition diaries, the Overactive Bladder Questionnaire (OAB-q) and the King's Health Questionnaire (KHQ) were included in part or in total in three OAB clinical trials. Discriminant validity for full and dichotomized responses was assessed with anovas models and correlations were used to evaluate construct validity.
