Psychometric Adequacy of Women's Sexual Well-being Scale in Married Women: Validity, Reliability and Factor Structure

The aim of this study was to investigate the validity, reliability and factor structure of the Female Sexual Well-Being Scale in Iranian married women. For this purpose, a sample of 297 married women (with a mean age of 33.7 years and an age range of 24 to 45 years) was selected by simple random sampling. The Psychological Well-Being Questionnaire (Reef, 1995) and Women's Sexual Well-Being Scale (Rosen et al., 2009) were completed by the sample group. The validity of this scale was assessed using exploratory and confirmatory factor analysis methods, convergent and simultaneous validity. The reliability of the scale was evaluated by two methods of Cronbach's alpha and halving. The results of factor analysis using principal component method and varimax rotation showed that this scale consists of 4 factors with the titles of interpersonal relationships, cognitive-emotional domain, physical stimulation and orgasm satisfaction, which is more than 66% of the variance. They explain the whole. The convergent validity of this scale indicated a satisfactory correlation between the dimensions of the female sexual well-being scale and the total score. To determine the simultaneous validity of the scale, the correlation between the dimensions of the female sexual well-being scale and the psychological well-being scale was used, which indicated a favorable correlation (p <0.001). Cronbach's alpha and halving coefficients for the whole scale and its dimensions ranged from 0.63 to 0.82. The final result is that the Persian form of the Women's Sexual Welfare Scale has good validity and reliability in Iranian society and can be used in research, educational and clinical situations.
