Reliability and validity of the Thai version of the genital appearance satisfaction questionnaire

Abstract

Background: The genital appearance satisfaction (GAS) questionnaire was constructed to measure women’s feelings toward their own genitals in a broader spectrum. The Thai language GAS questionnaire is valuable for clinical and research purposes.

Objectives: This study aimed to assess the reliability and validity of the Thai version of the GAS questionnaire.

Methods: For this study, 90 Thai women attending the gynecologic outpatient clinic at King Chulalongkorn Memorial Hospital between July 2017 and June 2018 were recruited. Ten participants dropped out because they did not answer the second questionnaire. The original English version of the GAS questionnaire was translated into the Thai version and backward translated by another linguist. The questionnaire content was then validated by two urogynecologists. After informed consent was obtained, the participants were asked to complete the Thai version of the GAS questionnaire and the Thai version of the female sexual function index (FSFI) at their first visit and only the Thai version of the GAS questionnaire at a 2-week interval (sent back by mail).

Results: The average age of the participants was 33.9 ± 7.0 years. The mean Thai version of the GAS questionnaire total scores at week 0 and week 2 were 6.0 ± 3.0 and 6.4 ± 2.8, respectively. The total score’s internal consistency (Cronbach’s alpha) was 0.9, and the intraclass correlation coefficient of the total score was 0.9 (0.8, 0.9).

Conclusion: We found that the Thai version of the GAS questionnaire is reliable and valid. It can be used to evaluate the satisfaction of genitalia in Thai women.
