بررسی روایی و پایایی نسخه فارسی پرسشنامه رضایت جنسی لارسون در زوجین نابارور ایرانی

Background and Objectives: Infertility is one of the most important crises in the lives of couples, which create psychological consequences beside the economic, social and individual problems,. Decreased sexual satisfaction is one of the consequences of infertility. Given the importance of this concept in the life of infertile couples, a tool to measure the sexual satisfaction of this group of people is necessary. Thus, the study aimed to assess the psychometric properties of the Persian version of the LSSQ in Iranian infertile couples in 2013. Methods: In this methodological study, 150 Iranian infertile couples completed the 25-item Larson's sexual satisfaction questionnaire in Qazvin. Its reliability was determined by the calculation of Cronbach's alpha coefficient. Exploratory and confirmatory factor analyses were done by SPSS-AMOS22. Results: The internal consistency of the sexual satisfaction questions estimated with Cronbach's alpha was more than 0.7. Exploratory factor analysis was used to evaluate the construct validity of the questionnaire which showed 4 factors (desire to have sexual relations, sexual attitude, quality of sex life, and sexual compatibility) with Eigen values greater than one. Four latent factors explained 53.21% of the total variance. Confirmatory factor analysis confirmed the final model of the construct of the questionnaire. Conclusion: The results of study showed that the Persian version of LSSQ has a suitable validity and reliability in the Iranian infertile couples. Factor analysis confirmed that the LSSQ had a multi-dimensional structure.
