Study Objectives:

This study evaluated the effect on infant sleep of a novel intervention (Play2Sleep) that combined infant sleep information with self-modeled video feedback on parent-infant interactions.

Methods:

An explanatory sequential mixed methods design consisting of a randomized controlled trial with 63 mother-father-infant triads randomized to Play2Sleep or comparison home visit interventions was used. We used RM-ANCOVA to detect changes in infant night wakings, nocturnal wakefulness, and sleep durations and Wilcoxon signed rank test to evaluate changes in perception of infant sleep problems. Family interviews (n = 20) were used to explain the quantitative findings and analyzed qualitatively using thematic analysis.

Results:

Play2Sleep was effective in reducing maternal-reported infant wakefulness, F(1, 55) = 5.33, p = .03, partial η² = .09, and the number of paternal-reported naps, F(1, 58) = 4.90, p = .03, partial η² = .08. Parents in the Play2Sleep group reported significant improvements in problematic infant sleep that were not observed in the comparison group, however Play2Sleep was not effective in reducing the number of parent-reported night wakings. Information overwhelm, learning infant cues, and working together with a subtheme of father involvement were key qualitative themes developed to explain the quantitative results. Unplanned exploratory analyses revealed a significant improvement in maternal depression symptoms in the Play2Sleep group.

Conclusions:

This study suggests Play2Sleep could improve infant sleep by promoting parental awareness of infant cues and father involvement and improving maternal depression. Additional research is needed to determine the optimal number and timing of sessions.

Play2Sleep 对母亲和父亲报告的婴儿睡眠的影响：一项随机对照试验的顺序解释混合方法研究

学习目标：

本研究评估了一种新颖的干预措施 (Play2Sleep) 对婴儿睡眠的影响，该干预将婴儿睡眠信息与自我建模的亲子互动视频反馈相结合。

方法：

使用了一种解释性顺序混合方法设计，该设计包括一项随机对照试验，其中 63 个母亲-父亲-婴儿三合会随机分配到 Play2Sleep 或比较家访干预措施。我们使用 RM-ANCOVA 检测婴儿夜间觉醒、夜间觉醒和睡眠持续时间的变化，并使用 Wilcoxon 符号秩检验来评估婴儿睡眠问题感知的变化。家庭访谈（n = 20）用于解释定量结果，并使用主题分析进行定性分析。

结果：

Play2Sleep 可有效减少母亲报告的婴儿觉醒，F (1, 55) = 5.33，p = .03，部分 η ² = .09，以及父亲报告的小睡次数，F (1, 58) = 4.90，p = .03，部分 η ² = .08。Play2Sleep 组的父母报告说，在比较组中没有观察到有问题的婴儿睡眠有显着改善，但是 Play2Sleep 在减少父母报告的夜间醒来次数方面没有效果。信息淹没，学习婴儿线索，并与父亲参与的副主题一起工作是为解释定量结果而开发的关键定性主题。计划外的探索性分析显示，在 Play2Sleep 组中，母亲的抑郁症状有显着改善。

结论：

这项研究表明 Play2Sleep 可以通过提高父母对婴儿线索和父亲参与的意识以及改善母亲抑郁症来改善婴儿睡眠。需要额外的研究来确定会议的最佳数量和时间。
