The Female Sexual Function Index (FSFI)—A Systematic Review of Measurement Properties

Key Points

To evaluate the measurement properties of the Female Sexual Function Index (FSFI), specifically structural validity, reliability, and other metrics.
Conducted a systematic review of FSFI measurement properties
Assessed structural and construct validity, reliability, and responsiveness
Evaluated measurement invariance across cultures and subpopulations
FSFI-19 requires further validation for structural validity and measurement invariance
FSFI-6 shows need for tests on reliability and unidimensionality
Measurement error and responsiveness of both versions also require more research

Abstract

The FSFI requires more research on structural validity (FSFI-19 and FSFI-6), reliability (FSFI-6), construct validity (FSFI-19), measurement error (FSFI-19 and FSFI-6), and responsiveness (FSFI-19 and FSFI-6). Further corroboration of measurement invariance (both across cultures and across subpopulations) in the factor structure of the FSFI-19 is necessary, as well as tests for the unidimensionality of the FSFI-6.
