Validation of decision-making outcomes for female pelvic floor disorders.

Abstract

This study was undertaken to modify and validate the Satisfaction with Decision Scale and Decision Regret Scale for women who have undergone surgery for pelvic floor disorders. We adapted the Satisfaction with Decision Scale and Decision Regret Scale for women with pelvic floor disorders. Forty-five women who underwent surgery for pelvic floor disorders were enrolled postoperatively and completed the Satisfaction with Decision Scale-Pelvic Floor Disorders and Decision Regret Scale-Pelvic Floor Disorders on 2 occasions, 1 week apart. Face and content validity of the Satisfaction with Decision Scale-Pelvic Floor Disorders and Decision Regret Scale-Pelvic Floor Disorders were confirmed by patient interviews and expert panel. The Satisfaction with Decision Scale-Pelvic Floor Disorders and Decision Regret Scale-Pelvic Floor Disorders were internally consistent (Cronbach's alpha: .95 and .88, respectively) and reproducible (intraclass correlations: 0.82 and 0.84, respectively). Larger improvements between preoperative and postoperative Pelvic Floor Distress Inventory-20 and Pelvic Floor Impact Questionnaire-7 scores were positively correlated with the Satisfaction with Decision Scale-Pelvic Floor Disorders (r = 0.42 and 0.49, respectively), and negatively correlated with the Decision Regret Scale-Pelvic Floor Disorders (r = -0.60 and -0.63, respectively). The Satisfaction with Decision Scale-Pelvic Floor Disorders and Decision Regret Scale-Pelvic Floor Disorders were negatively correlated with each other (r = -0.55). The Satisfaction with Decision Scale-Pelvic Floor Disorders and Decision Regret Scale-Pelvic Floor Disorders are reliable and valid decision-making outcome measures for women with pelvic floor disorders.
