Abstract
Background: The lack of a valid and reliable Thai version of the Female Sexual Function Index (FSFI) applicable across relationship statuses and sexual orientations represents an important gap in Thailand.
Aim: This study aimed to develop and validate a Thai version of the FSFI (FSFI-TH) for use among Thai women with varied marital statuses and sexual orientations.
Methods: A total of 243 women aged 18-66 years (mean age 31.96 ± 9.78 years) participated in the study. The FSFI-TH was developed through forward translation, back translation, expert committee review, and a pilot study. Reliability was assessed using Cronbach's alpha coefficients and test-retest reliability with intraclass correlation coefficients. Validity was evaluated on aspects of content and construct validity.
Outcomes: The primary outcomes were the psychometric reliability and validity of the FSFI-TH.
Results: Item-Objective Congruence demonstrated good content validity, with linguistic refinements informed by the pilot study. The FSFI-TH showed strong internal consistency, with Cronbach's alpha values above .80 for the total scale and most domains. Construct validity assessed using principal component analysis revealed a five-factor structure, with the Desire and Arousal domains loading onto a single factor.
Clinical implications: The FSFI-TH is a valid and reliable instrument for assessing sexual function among Thai women.
Strengths and limitations: A key strength of this study is the inclusive applicability of the FSFI-TH across diverse relationship statuses and sexual orientations. However, the limited representation of postmenopausal women means that its applicability in this group should be interpreted with caution.
Conclusion: The FSFI-TH is a valid and reliable instrument for measuring multidimensional aspects of sexual function in Thai women.
期刊介绍：
Sexual Medicine is an official publication of the International Society for Sexual Medicine, and serves the field as the peer-reviewed, open access journal for rapid dissemination of multidisciplinary clinical and basic research in all areas of global sexual medicine, and particularly acts as a venue for topics of regional or sub-specialty interest. The journal is focused on issues in clinical medicine and epidemiology but also publishes basic science papers with particular relevance to specific populations. Sexual Medicine offers clinicians and researchers a rapid route to publication and the opportunity to publish in a broadly distributed and highly visible global forum. The journal publishes high quality articles from all over the world and actively seeks submissions from countries with expanding sexual medicine communities. Sexual Medicine relies on the same expert panel of editors and reviewers as The Journal of Sexual Medicine and Sexual Medicine Reviews.
