Description
Summary:The Hurlbert Index of Sexual Compatibility is a questionnaire for determining sexual compatibility between two partners who have intimate relationships. This study aimed to determine the psychometric properties of the index in the Iranian population. The original questionnaire was translated into Persian. The face and content validity of the index was assessed by interviews of the target group and judgment by an expert panel. The convergent validity of the index was assessed by a native reliable questionnaire. Structural validity was assessed using exploratory factor analysis in 550 eligible males and females in Zanjan, Iran. The reliability of the instrument was assessed by determining internal consistency. The face validity of the 24 items of the original questionnaire was confirmed. The content validity ratio of items was higher than 0.59, and their validity index was higher than 0.79. Four factors were identified based on exploratory factor analysis, accounting for 53.67% of the variance. However, the highest variance was related to the first factor (34.4%), and the other factors accounted for very little variance. Therefore, as was the case for the original questionnaire, one domain was considered in Iran. The reliability of the questionnaire was confirmed by Cronbach’s alpha of 0.87. We conclude that this questionnaire can be used by researchers and family counselors to evaluate the sexual compatibility of Iranian couples.
