Abstract

OBJECTIVES:

To perform the linguistic and psychometric validation of the Spanish version of the BSW (Benefit, Satisfaction and Willingness to continue) questionnaire.

MATERIAL AND METHODS:

Epidemiologic, observational, multicenter, prospective (October 2008-February 2009) study in patients ≥40 years old with de novo overactive bladder syndrome who start treatment with antimuscarinics by physicians assessment. Data was recorded at baseline (face-to-face) and the follow-up of the study after 1 and 3 months (closed surveys by phone). Morisky-Green questionnaire was used to assess compliance. Bladder Control Self-assessment Questionnaire (B-SAQ) and BSW questionnaire were completed, performing the validation of BSW.

RESULTS:

312 evaluable patients were recruited, 93 remained until the 3 months visit. 65% and 71% of patients were not compliant with treatment at 1 and 3 months, respectively. The correlation between the BSW and the B-SAQ questionnaires after 1 and 3 months was moderate and statistically significant. The internal consistency between the BSW questionnaire items was high (Cronbach alpha: 0,89 at 1 month and 0,84 at 3 months). 92% of patients understood the questions and 84% were able to fill the BSW questionnaire without need of previous instructions (N=25).

CONCLUSIONS:

The BSW questionnaire has been shown to be a feasible, valid and reliable tool to know the patient self-assessment of the treatment, according to its psychometric properties.
