BACKGROUND: Addressing psychological trauma after childbirth requires accurate measurement of its prevalence, risk factors, and outcomes using validated instruments that distinguish perceptions of traumatic birth, subclinical post-traumatic stress (PTS) symptoms, and symptoms meeting a diagnostic threshold. OBJECTIVE: The purpose of this study was to review literature on psychological trauma following childbirth and appraise instruments that measure postpartum PTS. METHODS: In January 2020, the authors searched for and evaluated peer-reviewed studies that quantitatively measured PTS following hospital-based live births in the United States, United Kingdom, Canada, Australia, Norway, Sweden, and Switzerland; 37 articles were selected and evaluated. RESULTS: Levels of post-traumatic stress disorder were most commonly measured, followed by PTS symptoms. Diagnostic instruments suggested lower PTS prevalence estimates than those screening for or assessing PTS symptoms. Community samples yielded lower prevalence estimates than samples recruited from the internet or settings specifically addressing mental health. Measurement sooner after birth yielded higher estimates. CONCLUSION: Study design, sample characteristics, instruments, and timing of measurements likely impact postpartum PTS prevalence estimates. Variation in these characteristics make it difficult to draw conclusions on the prevalence of postpartum PTS. Researchers should consider the appraisal of measurement tools presented here and use rigorous study methodology when studying traumatic birth experiences and evaluating interventions.
