Abstract
Background & Aim: Urinary incontinence is a common disorder in women. Pelvic floor muscle exercise is one of the effective treatment methods. Self-efficacy is considered an effective and strong predictor of willingness to perform and continue these exercises. In Iran, there is no appropriate tool for assessing self-efficacy. So this study was performed to determine the psychometric properties of the Broome scale in women with urinary incontinence.
Methods & Materials: A psychometric study of the Broome scale was conducted on women with urinary incontinence who referred to health centers affiliated to Tehran University of medical sciences in 2015.In this study, following processes were implemented: translation, back translation, face validity, content validity using CVR and CVI, reliability using Cronbach’s α coefficient, and construct validity using explanatory factor analysis.
Results: The face validity was confirmed through the modification of ambiguous items based on the patients’ views. Content validity (CVR= 0.8 and CVI= 0.8 to 0.9) and reliability (Cronbach’s α= 0.96) were also confirmed. Explanatory factor analysis showed two factors with eigen value more than 1 including pelvic floor exercise self-efficacy in usual and special situations. These factors explained 82.08 percent of the total variance.
Conclusion: The reliability and validity of the Broome scale were confirmed for using by Iranian women with urinary incontinence, and this scale can be used to measure these women's self-efficacy in performing pelvic floor exercises.

Abstract
Background & Aim: Assessment of sexual health literacy requires an appropriate tool. The purpose of this study was to develop and validate a questionnaire to evaluate the level of sexual health literacy among Iranian adults.
Methods & Materials: This study was designed in two phases in Tehran during 2017-2018. In the first step, the questionnaire was developed by item generation through expert panel and literature review. In the second step, the assessment of psychometric properties of the questionnaire including face, content, and structure validity (exploratory factor analysis) and convergence criterion (using general health literacy questionnaire) were done. Reliability of the questionnaire was assessed by internal consistency (Cronbach’s alpha) and intraclass correlation coefficient (ICC). Data were analyzed using the SPSS software version 21.
Results: The content validity indices (CVI and CVR) for all items were 0.84 and 0.81, respectively. Exploratory factor analysis identified four factors including skills of access, reading and understanding, evaluation and analysis, and application of information that explained %68.1 of the variance. Convergent validity of the questionnaire showed a correlation between the questionnaire’s dimensions and general health literacy questionnaire in the range of 0.31 to 0.70. The SHELA showed a high internal consistency reliability with Cronbach’s alpha, ranging from 0.84 to 0.94 and intraclass correlation coefficient (ICC), ranging from 0.90 to 0.97.
Conclusion: The psychometric assessment of the 40-item questionnaire (SHELA) indicates desirable validity and reliability. This questionnaire is suggested for assessing the level of sexual health literacy of adults in future studies.
