婴儿期是一个快速发展的时期，此时照顾行为的质量可能对儿童的长期功能特别重要。在这个照顾行为的关键时期，父母会经历睡眠的变化，这可能会影响他们提供敏感照顾的能力。本研究调查了母亲的睡眠障碍与母亲与婴儿互动时的敏感性水平和轨迹之间的关系。在产后18周，观察母亲和她们的婴儿在家进行10分钟的“自由游戏”互动。母亲的夜间睡眠用活动记录仪客观测量，用睡眠日记主观测量。母亲的敏感性以两分钟为间隔进行编码，以表征在自由游戏互动过程中敏感性的变化。我们采用探索性因子分析降低了母亲睡眠的客观和主观测量的维度，确定了主观睡眠障碍和客观睡眠连续性因素。使用多层次模型，我们发现客观睡眠连续性较差的母亲在相互作用中对婴儿的敏感性降低。母亲自我报告的睡眠障碍与母亲的敏感性无关。虽然未来的研究需要确定可能解释所观察到的睡眠连续性差与无法维持对婴儿的敏感性之间的关联的机制，但在设计干预措施以提高护理质量时，母亲产后睡眠连续性可能是考虑的一个因素。
Infancy is a period of rapid development when the quality of caregiving behavior may be particularly consequential for children’s long-term functioning. During this critical period for caregiving behavior, parents experience changes in their sleep that may affect their ability to provide sensitive care. The current study investigated the association of mothers’ sleep disturbance with both levels and trajectories of maternal sensitivity during interactions with their infants. At 18 weeks postpartum, mothers and their infants were observed during a home-based ten-minute “free play” interaction. Mothers’ nighttime sleep was objectively measured using actigraphy and subjectively measured using sleep diaries. Maternal sensitivity was coded in two-minute intervals in order to characterize changes in sensitivity across the free play interaction. We used exploratory factor analysis to reduce the dimensionality of the objective and subjective measures of mothers’ sleep, identifying a subjective sleep disturbance and an objective sleep continuity factor. Using multi-level modeling, we found that mothers with poorer objective sleep continuity evidenced decreasing sensitivity toward their infants across the interaction. Mothers’ self-reports of sleep disturbance were not associated with maternal sensitivity. Although future research is necessary to identify the mechanisms that may explain the observed association between poor sleep continuity and the inability to sustain sensitivity toward infants, mothers’ postpartum sleep continuity may be one factor to consider when designing interventions to improve the quality of caregiving.
