Analysis of the psychometric evidence of the Female Sexual Function Index (FSFI) & measurement invariance across relationship status & age generations in a Chilean sample.

ABSTRACT:

Background

Inconsistencies in the Female Sexual Function Index (FSFI) factor structure and current research and clinical guidelines highlight the need for continued exploration of its psychometric evidence. Furthermore, only one study has assessed its measurement invariance (MI), while the only FSFI psychometric study conducted in Chile lacks quality and representativity.

Aim

Therefore, this study aimed to evaluate the psychometric properties of the FSFI (ie, structural and convergent validity, and reliability) in a Chilean sample of women, while also examining MI across relationship status and age groups.

Method

A sample of 2595 sexually active adult women (M _age = 32.10, SD _age = 10) was derived from a broader Chilean study (Chile
