Αdaptation and Psychometric Validation of the Female Genital Self-Image Scale in a Greek Population

Female genital self-image is an important factor influencing women's sexual function and overall psychological well-being. However, a culturally adapted and validated instrument for assessing this construct in the Greek population has not yet been established. This study was aimed at conducting a cross-cultural adaptation and evaluating the psychometric properties of the Female Genital Self-Image Scale (FGSIS) in a Greek female population.

A total of 221 women participated in this cross-sectional study, completing the translated seven-item FGSIS and the Female Sexual Function Index (FSFI). Evaluation included internal consistency (Cronbach's alpha), test-retest reliability (intraclass correlation coefficient, ICC) and structural validity via confirmatory factor analysis (CFA). Hypothesis testing examined the associations between FGSIS and FSFI scores.

The mean FGSIS score was 22.23 (SD 3.91). The scale demonstrated excellent internal consistency (α = 0.90) and preliminary evidence of fair-to-substantial test-retest reliability (ICC 0.25-0.78; n = 17). CFA strongly supported a unidimensional structure (confirmatory fit index, CFI 0.99, Tucker-Lewis index 0.99, root mean square error of approximation, RMSEA 0.06, standardised root mean squared error; SRMR = 0.02). Weak but significant positive correlations emerged between FGSIS and total FSFI scores and most domains, excluding pain. Furthermore, higher education, nulliparity and not being in a steady relationship independently predicted a more positive genital self-image.

The Greek FGSIS appears to be a simple, valid and reliable tool for assessing female genital self-image in Greek women. Its application will facilitate clinical evaluation and research regarding women's sexual health in Greece.
