Abstract
ABSTRACT This study aimed to translate, create a cut-off point, and assess the measurement properties of the female genital self-image scale (FGSIS) in Brazilian women. Content, structural, and construct validity, internal consistency, test-retest reliability, and measurement errors were assessed in this online study. FGSIS cut-off point to classify satisfaction with genital self-image (GSI) was performed using the Partial Credit Model (PCM). In total, 614 women (28.92±9.80 years) participated in the study. The FGSIS had a one-factor structure and adequate measurement properties. FGSIS≥22 points classify women as satisfied with their GSI. Therefore, FGSIS is a simple, valid, and reliable measure to assess GSI in Brazilian women.
