Abstract

Background

Female sexual dysfunction is a common condition that extremely affects reproductive health and quality of life. To assess this health condition, a valid and reliable questionnaire is required. The aim of this study was to translate and validate the Sexual Quality of Life-Female (SQOL-F) questionnaire in Iran.

Method

Forward-backward procedure was applied to translate the questionnaire from English into Persian. After linguistic validation and pilot examination, a cross-sectional study was carried out and psychometric properties of the Iranian version of questionnaire were tested. One hundred reproductive aged, married, healthy and sexually active women completed the questionnaire. Reliability was assessed by internal consistency (Cronbach’s alpha), and test-retest (intraclass correlation coefficient) analyses. In addition, content, and face validity were assessed and the factor structure of the questionnaire was extracted by performing exploratory factor analysis.

Results

The mean age of participants was 33 (SD = 8.07) years, and the mean quality of sexual life score was 86.4 (SD = 1.78) ranging from 36 to 108. Most women were housewife (n = 92). Reliability evaluation revealed high internal consistency and good test-retest reliability. The Cronbach’s alpha coefficient was 0.73 and intraclass correlation coefficient (ICC) was 0.88. The mean scores for the content validity index (CVI) and the content validity ratio (CVR) were 0.91 and 0.84, respectively. The results of exploratory factor analysis (EFA) indicated a four-factor solution for the questionnaire that jointly accounted for 60.8% of variance observed.

Conclusion

The findings from this study suggest that the Iranian version of SQOL-F questionnaire has good psychometric properties and it will be useful to assess the female sexual quality of life in reproductive health care settings.
