Reliability and validity of the continence self-efficacy scale in Turkish women with urinary incontinence

Abstract

This study investigated the psychometric properties of the Continence Self-Efficacy Scale. Data was collected from 128 women who had urinary incontinence using the following instruments: the Continence Self-Efficacy Scale, the Broome Pelvic Muscle Exercise Self-Efficacy Scale, the International Consultation on Incontinence Questionnaire Short Form, and the Beck Depression Inventory. The validity of the Continence Self-Efficacy Scale was investigated using confirmatory factor analysis and convergent and divergent validity analyses. The reliability of the Continence Self-Efficacy Scale was examined in terms of internal consistency and testretest correlations. Confirmatory factor analysis indicated a three -factor model that had acceptable goodness-of-fit indices. The convergent validity of the Continence Self-Efficacy Scale was supported by a positive correlation between the Continence Self-Efficacy Scale and the Broome Pelvic Muscle Exercise Self-Efficacy Scale. The divergent validity of the Continence Self-Efficacy Scale was supported by negative relationships between the Continence Self-Efficacy Scale and the Beck Depression Inventory. The Cronbach's alpha values regarding internal consistency were 0.94 for the overall scale and 0.920.93 for the subscales. Testretest correlations were 0.75 for the overall scale and 0.520.74 for the subscales. The Continence Self-Efficacy Scale is a valid and reliable instrument for use in Turkish women with urinary incontinence.
