Early mother-infant interactions within the context of childbirth-related posttraumatic stress symptoms.

BACKGROUND

Childbirth may lead to perinatal mental health issues, such as childbirth-related posttraumatic stress symptoms (CB-PTSS), depression, and anxiety. Despite well explored mother-infant interactions in the context of maternal depression and anxiety, only limited studies investigated mother-infant interactions in the context of CB-PTSS, which is the aim of the present study.

METHODS

One-hundred mother-infant dyads in the French speaking part of Switzerland were classified into three groups: birth-related symptoms (BRS, i.e., symptoms of re-experiencing and avoidance) (n = 20), general symptoms (GS, i.e., symptoms of negative cognition and mood and hyperarousal) (n = 46), and non-symptomatic (NS) (n = 34) based on maternal report on PTSD Checklist for DSM-5 (PCL-5). At six months postpartum, mother-infant interactions were video-recorded and their quality was assessed using the Global Rating Scale. Data was analyzed using ordinal logistic and negative binomial regressions.

RESULTS

In the adjusted model, mothers in BRS group engaged in more frequent coercions compared to the NS group (B = -1.46, p = 0.01, 95%CI = -2.63, -0.36) and showed lower reciprocity in their interactions with their infants compared to the GS group (B = 1.21, p = 0.03, 95%CI = 0.05, 2.37).

LIMITATIONS: The use of a cross-sectional design limited the exploration of how consistent these findings are regarding mother-infant interactions between groups over time.

CONCLUSIONS

Mothers with higher BRS may need support to improve interactions with their infants. Future studies should consider longitudinal design to observe mother-infant interaction changes between CB-PTSS groups over time.
