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.
