Abstract: Very preterm birth (<32 weeks of gestation) heightens the risk for developmental and behavioral problems, but individual outcomes vary greatly. We evaluated whether mother–toddler dyadic interaction quality, assessed longitudinally at 14, 20, and 30 months (corrected), could account for unique variance in very preterm and full-term children’s mental, motor, and behavioral outcomes on the Bayley Scales of Infant Development at 30 months. Participants included 70 mother–toddler dyads (44 with male children, 38 full term and 32 very preterm) followed prospectively from birth to 30 months. In hierarchical regressions controlling for socioeconomic status, dyadic interaction quality at 20 and 30 months explained unique variance in toddlers’ 30-month mental scores and was the sole predictor of orientation/engagement and emotion regulation scores. In contrast, very preterm status was the primary predictor of 30-month motor and movement quality scores. Dyadic interaction quality also mediated the association between very preterm status and specific 30-month outcomes. Implications for interventions are discussed.

母婴互动质量作为非常早产儿的发展和行为结果的预测指标

摘要：早产（小于32周）会增加发生发育和行为问题的风险，但个人结局差异很大。我们评估了在14个月，20个月和30个月（校正后）进行纵向评估的母婴二元互动质量是否可以解释婴儿的Bayley量表对早产和足月儿童的心理，运动和行为结果的独特差异在30个月的开发时间。参加者包括出生后至30个月的70个母婴双胞胎（44个带男婴，38个足月和32个非常早产）。在控制社会经济地位的等级回归中，在20和30个月时的二元互动质量可以解释幼儿30个月的心理得分的独特差异，并且是定向/参与和情绪调节得分的唯一预测指标。相反，非常早产的状态是30个月运动和运动质量评分的主要预测指标。二进位互动质量还介导了非常早产状态与特定的30个月结果之间的关联。讨论了干预的含义。
