Abstract
Objectives: The female genital self-image scale questionnaire (FGSIS) was constructed to measuring feeling towards female’s own genital in a broader spectrum. The purposes of the study were to assessing reliability and validity of the Thai version FGSIS.
Materials and Methods: After the institutional review board approval, 77 Thai women attending the gynecologic outpatient clinic at King Chulalongkorn Memorial hospital were recruited between February and July 2020 in this study. Seven participants drop-out because they did not answer the second questionnaire. The original English-version of FGSIS was translated into Thai version and backward translated by another linguist then the content was validated by the two urogynecologists at our department. After the informed consent were done, the patients were asked to complete the Thai version of FGSIS and female sexual function index (FSFI) questionnaire at first visit and only Thai version of FGSIS questionnaires at 2-week interval were completed and sent back by mail.
Results: Our findings indicated good reliability of the Thai-version of FGSIS (Cronbach’s alpha 0.80, test-retest reliability 0.79 (0.67-0.87)). Good correlation was found between the Thai-version of FGSIS and the Thai-version of FSFI (Pearson’s correlation coefficient = 0.62).
Conclusion: The Thai-version of FGSIS was found to be reliable and valid. It could be used for evaluating the satisfaction of genital appearance in Thai women for research and clinical use.
