Purpose: This study aimed to develop a valid and reliable tool for evaluation of sexual health assessment in infertile women.
Methods: This was a mixed exploratory study consisting of two phases. At phase one, we reviewed the existing instruments and interviewed 20 infertile women to generate an item pool. Then, the research team examined items and invited a panel of experts (n = 15) and a group of infertile women (n = 10) to review the items to establish content and face validity. Accordingly, the provisional version of the questionnaire containing 62 items was provided. At phase two, a cross-sectional study was conducted to evaluate the questionnaire. The structural validity was examined by performing exploratory factor analysis. Internal consistency was estimated by the Cornbach's alpha coefficient and test-retest analysis was performed to assess stability.
Results: The final questionnaire consisted of 45 items and a total of 372 infertile women completed the questionnaire. The mean age of women was 30.8 (SD 6.0) years and this was 5.6 (SD 4.2) for duration of infertility. The results obtained from exploratory factor analysis indicated a five-factor solution for the questionnaire that jointly explained 51.39% of variance observed. At this stage, 15 items were deleted due to low factor loading. The analysis of internal consistency and stability yielded satisfactory results (Cronbach alpha: 0.93, ICC 0.97, respectively). Further analysis indicated that lower sexual health in infertile women was associated with education (OR for primary education 2.61, 95% CI 1.44-4.76, P = 0.002) and being housewife (OR 2.35, 95% CI 1.15-4.83, P = 0.01).
Conclusion: The findings showed that the Sexual Health Assessment Tool for Infertile Women (SEHAT-IW) is a reliable and valid instrument to assess infertile women's sexual health.
