Translation and psychometrics of the Persian version of the Pregnancy Sexual Response Inventory (PSRI)

Sexual activity changes during pregnancy due to hormonal and physical changes in pregnant women. This leads to a higher prevalence of sexual dysfunction in pregnancy. Evaluation of sexual function with special tools is necessary to determine sexual dysfunction during pregnancy. Pregnancy Sexual Response Inventory is one of these tools. The present study was performed aimed to translate and determine the psychometric properties, and validate the Pregnancy Sexual Response Inventory (PSRI).

This correlation type descriptive-analytical study was translated from English to Persian "Forward / Backward" to translate, psychometrics, and validate the Pregnancy Sexual Response Inventory (PSRI) in 2021. After consulting the experts and pregnant mothers, the content and face validity of the scale were determined qualitatively. The final version of the questionnaire was completed by 260 pregnant women in Rasht, chosen via convenience sampling. The reliability of the questionnaire was assessed by Cronbach's alpha coefficient and Inter class correlation coefficient (ICC). The reliability and validity of the questionnaire structure was done by confirmatory factor analysis using AMOS software and other statistical analyzes using SPSS statistical software. P< 0.05 was considered statistically significant.

Intra-class correlation was shown for each scale between 0.602 and 0.902. There was also a moderate to high correlation between each subscale and the total score of the PSRI questionnaire. All indices of goodness indicated that all subscales of this questionnaire are suitable to measure pregnancy sexual response and activity.

The psychometric properties of the PSRI Scale showed the high reliability and validity of this scale and the possibility of using this tool in Iran.
