Abstract

Sexual adjustment along with balance and moderation in sexual relationships are regarded as major factors contributing to a happy and successful married life. Valid and reliable instruments, such as the Dyadic Sexual Communication Scale (DSC), are used as a means to investigate dyadic sexual communications. The present study aimed at translating, assessing the psychometric properties, and validating the Persian version of the Dyadic Sexual Communication Scale. In this methodological study, the DSC Scale was “forward-backward” translated. After consulting the experts and couples, the content and face validity of the scale were determined qualitatively. The final version of the scale was completed by 300 married respondents residing in the city of Rasht chosen via convenience sampling. The reliability of the scale was assessed using Cronbach’s alpha coefficient and test-retest method. Exploratory and confirmatory factor analysis were conducted to determine the validity of the scale. Cronbach’s alpha for all items was calculated as 0.814. The Sample size was calculated using KMO sampling adequacy test as 0.802. Some of the fit indices of factor analysis indicated that the two-factor model has best fit the data. Psychometric properties of the Persian version of the DSC Scale indicate a high level of reliability and validity and its applicability in Iran. © 2018, © 2018 College of Sexual and Relationship Therapists.
