The goal of this study was to examine the effects of preterm birth and maternal childbirth‐related posttraumatic stress and parenting stress on maternal mind‐mindedness (MM). The study also investigated the effects of perceived social support on parenting stress and MM. Sixty‐five preterm (N = 32) and full‐term (N = 33) mother–infant dyads were observed at 6 months. Measures of maternal MM were obtained from observations of mother–infant interaction. Mothers also provided ratings of their posttraumatic stress disorder (PTSD) symptoms, parenting stress, and perceived social support via an online survey. Experiencing a preterm birth did not affect mothers’ use of mental state descriptors during mother–infant interaction. Neither childbirth‐related posttraumatic stress nor parenting stress directly affected maternal ability to comment on the child's mental states appropriately. However, at medium and high levels of perceived social support, a negative association between parenting stress and MM was observed. Maternal perception of being emotionally supported by significant others promoted MM in mothers showing low or mild levels of parenting stress, but not in mothers experiencing high stress in parenting their infants. Results suggest that a proclivity to MM might be affected by the interaction between parenting stress and social support, rather than by childbirth‐related variables, such as prematurity.

早产儿和足月儿母亲的思想意识和育儿压力：感知社会支持的调节作用

本研究的目的是检查早产和产妇分娩相关的创伤后压力和育儿压力对产妇心态 (MM) 的影响。该研究还调查了感知社会支持对育儿压力和 MM.65 早产 ( N  = 32) 和足月 ( N = 33) 在 6 个月时观察到母婴成对。母亲 MM 的测量是从母婴互动的观察中获得的。母亲们还通过在线调查对她们的创伤后应激障碍 (PTSD) 症状、养育压力和感知到的社会支持进行了评级。经历早产不会影响母亲在母婴互动期间使用精神状态描述符。与分娩相关的创伤后压力和育儿压力都不会直接影响母亲适当评论孩子心理状态的能力。然而，在感知社会支持的中等和高水平上，观察到育儿压力与 MM 之间存在负相关。母亲认为得到重要他人的情感支持会促进母亲的 MM 表现出低或轻度的育儿压力，但在育儿过程中承受高压力的母亲中则不然。结果表明，对 MM 的倾向可能受育儿压力和社会支持之间相互作用的影响，而不是受分娩相关变量（如早产）的影响。
