Abstract

Background & Aims: Sexual satisfaction has been considered as one of the basic physiological needs, with significant impact on the health of individuals and society. In order to understand this concept better and dealing with crises and issues arising from it, the development of a specific questionnaire for measuring sexual satisfaction among Iranian couples is required. The present study aimed to assess the validity and reliability of the Persian Version of Index of Sexual Satisfaction in couples in 2013. Methods: In this methodological study, 150 Iranian couples living in Qazvin completed the 25- item Larson's sexual satisfaction questionnaire. Reliability was determined by the calculation of Cronbach's alpha coefficient and intra-class correlation coefficients. Exploratory and confirmatory factor analysis was done by SPSS-AMOS22. Results: Cronbach's alpha values for all positives and negative items were above 0.70. By using exploratory principal components analysis, with Varimax orthogonal rotation and an eigenvalue cut-off of 1.0, three factors were produced that explained more than 42.73% of the data. Confirmatory factor analysis confirmed the final factor construct of Larson sexual Satisfaction questionnaire. Conclusion: Persian version of Larson sexual Satisfaction questionnaire has suitable validity and reliability to be used among the Iranian couples. The factor analysis demonstrated that Larson sexual Satisfaction questionnaire has a multi-dimensional structure. With consideration of the proper psychometric characteristics, this questionnaire can be used to measure sexual satisfaction in this population
