Interpersonal Exchange Model of Sexual Satisfaction Questionnaire (IEMSS): Psychometric Properties of the Persian Version within an Iranian Population

The aim of the present study was to investigate the psychometric properties of the Interpersonal Exchange Model of Sexual Satisfaction Questionnaire (IEMSS; Lawrance, Byers, & Cohen, 2011) within an Iranian population of approximately 300 men and women. The main conclusions of this study are that the structure of IEMSS is fairly well replicated in an Iranian sample. The amount of variance by factor analysis was good. Internal consistency and stability of IEMSS and its subscales are satisfactory and the subscales are reasonably stable across demographic variables. The discriminant validity and the ability of the scales to predict sexual satisfaction or dissatisfaction was excellent. The convergent and divergent construct validity was good. These results support the reliability and psychometric validity of the IEMSS in the assessment of sexual satisfaction in different samples.
