OBJECTIVES: to develop and validate an educational booklet for pregnant women experiencing pelvic girdle pain.
METHODS: this was a methodological development study conducted at the Federal University of São Carlos, Brazil. The educational booklet was developed following a comprehensive literature review and subsequently validated by healthcare professionals and pregnant women. Content and appearance were assessed using the Content Validity Index (threshold: 0.8 or higher) and the percentage of absolute agreement among participants (threshold: 75% or higher).
RESULTS: in the first stage, healthcare professionals rated the material with a mean global content validity of 0.93. In the second stage, pregnant women indicated an 89.2% agreement regarding its clarity, relevance, and usability. The final version, titled "What You Need to Know About Gestational Pelvic Pain", includes an introduction, the definition and location of pain, its relationship with pregnancy, and practical guidance for prevention and self-management.
CONCLUSION: the educational booklet met the acceptability standards established for validation and may contribute to improving prenatal care and self-management of pelvic girdle pain.
