Cross-cultural adaptation and psychometric validation of the Female Sexual Function Index-6 (FSFI-6) Bangla version.

Background: The 6-item Female Sexual Function Index (FSFI-6) is the shortened version of the widely used 19-item FSFI-19, designed for efficient screening of female sexual dysfunction in outpatient settings. However, this shorter FSFI-6 tool has not yet been validated for use in Bangladesh.

Aim: The purpose of this study was to culturally adapt and validate the FSFI-6 in Bangla.

Methods: The FSFI-6 was translated into Bangla using standard adaptation protocols. We interviewed 100 married, sexually active women aged 18 years and over from the outpatient and psychiatric sex clinic of a psychiatry department. Of these women, 50 were clinically diagnosed with sexual disorders based on the , 5th edition, criteria. After obtaining written informed consent, participants completed a semi-structured questionnaire to provide sociodemographic information and the Bangla-adapted version of the FSFI-6. We assessed reliability and construct validity using the Statistical Package for Social Sciences, version 25, along with Classical and Bayesian Instrument Development software.

Outcome: Study outcomes were internal consistency, factor structure, and sensitivity and specificity.

Results: The study involved 100 participants with a mean ± SD age of 30 ± 5.4 years, ranging from 18 to 48 years. The majority of respondents (54.34%) reported issues related to sexual desire. The overall mean score on the Bangla-adapted FSFI-6 was 18.4 ± 5.4. Reliability analysis showed a high internal consistency, with a Cronbach's alpha of 0.887 indicating robust reliability. Both inter-item correlations and item-total correlations were within the acceptable range. A cutoff value of 19 for the FSFI-6 demonstrated high discriminative power, effectively distinguishing between individuals with sexual disorders and those without sexual disorders or with other psychiatric conditions. The sensitivity at this cutoff was 96%, with a specificity of 100%.

Clinical Implications: The FSFI-6 Bangla version can be used to screen patients for female sexual dysfunction in an outpatient setting.

Strengths And Limitations: The internal consistency of this study, indicated by a Cronbach's alpha of 0.887, was robust. The instrument is time efficient, user friendly, and well suited for outpatient settings. However, the sampling technique utilized was nonrandomized, confined to a single institution, and did not incorporate assessments for concurrent validity or test-retest reliability.

Conclusion: The FSFI-6 Bangla version showed good reliability and validity in this study, supporting its usability as a valuable tool for screening sexual dysfunction in female.
