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.
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.
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).
The use of a cross-sectional design limited the exploration of how consistent these findings are regarding mother-infant interactions between groups over time.
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.
分娩可能导致围产期心理健康问题，如与分娩相关的创伤后应激症状（CB-PTSS）、抑郁和焦虑。尽管在母亲抑郁和焦虑的背景下已经很好地探讨了母婴互动，但只有有限的研究调查了 CB-PTSS 背景下的母婴互动，这就是本研究的目的。
瑞士法语区的 100 对母婴对被分为三组：与分娩相关的症状（BRS，即再体验和回避症状）（n=20）、一般症状（GS，即消极认知和情绪及过度警觉症状）（n=46）和无症状（NS）（n=34），基于母亲对 PTSD 检查表 DSM-5（PCL-5）的报告。在产后 6 个月，对母婴互动进行视频记录，并使用全球评分量表评估其质量。使用有序逻辑回归和负二项回归进行数据分析。
在调整后的模型中，与 NS 组相比，BRS 组的母亲更频繁地采用强制手段（B=-1.46，p=0.01，95%CI=-2.63，-0.36），并且与 GS 组相比，她们与婴儿的互动中互惠性较低（B=1.21，p=0.03，95%CI=0.05，2.37）。
使用横断面设计限制了对这些发现与各组母婴互动之间一致性的探索。
BRS 较高的母亲可能需要支持以改善与婴儿的互动。未来的研究应考虑采用纵向设计，观察 CB-PTSS 组之间母婴互动随时间的变化。
