BACKGROUND:
Previous research has identified several risk factors of childbirth-related post-traumatic stress disorder (CB-PTSD) involving a history of mental health issues, childbirth fear, childbirth related complications, negative birth experiences, operative birth, lack of support, poor coping and stress, and poor perception of support.

OBJECTIVES:
The aim of our study was to explore the role of satisfaction with care during childbirth in CB-PTSD symptoms.

METHODS:
CB-PTSD was measured with the City Birth Trauma Scale (CityBiTS), a questionnaire with 29 items distributed according to DSM-5 diagnostic criteria. A CityBiTS score >28 points was defined as CB-PTSD symptoms. Birth satisfaction was measured with the Birth Satisfaction Scale-Revised (BSS-R), a self-report questionnaire which measures satisfaction with birth in three categories. Logistic-regression was used to calculate odds ratios and 95% confidence intervals for the association between birth satisfaction and CB-PTSD, adjusted for age, relationship status, education, income, parity, mode of birth, postpartum depression and maternal and infant health-related problems during pregnancy and birth.

RESULTS:
Of 600 participants, 34 (5.7%) indicated symptoms of CB-PTSD. When adjusted for socio-demographic and pregnancy and birth-related factors, birth satisfaction was independently associated with symptoms of CB-PTSD. For each additional point on the birth satisfaction scale, the odds of having CB-PTSD symptoms decreased by about 16%. Factors significantly associated with CB-PTSD included primiparity, being single, a previous or current mental or psychological diagnosis and operative birth.

CONCLUSIONS:
Increased satisfaction with care was strongly associated with less symptoms of CB-PTSD. Screening for satisfaction with care may be an important factor in identifying women at risk for CB-PTSD.

KEY MESSAGE:
Increased satisfaction with care during labor and birth was strongly associated with less symptoms of CB-PTSD. Primiparity, being single, a psychological diagnosis and operative birth were associated with increased CB-PTSD symptoms. Emphasizing sense of control, effective communication and shared decision making during labor may reduce CB-PTSD symptoms. Poster session 2 (Group A)
