Tummy Time in Home-Environment

Infants aged 1-6 months of age were video-taped in their home (natural) environment during day-time hours. The goal was to capture tummy time (prone positioning). Video was collected using a Mobius dashcam and parents were instructed to turn the camera on in the morning and leave it running until the memory card filled up, usually 10-12 hours. Many other social and environmental interactions were captured. Our goal was to assess tummy time behavior including facilitators and barriers that served to extend or prematurely end a bout of tummy time. Some videos are not sound enabled, but most are.

研究对象为1至6月龄的婴儿，于日间时段在其居家（自然）环境中完成录像采集。本次采集的核心目标为记录俯卧互动时间（tummy time，即婴儿俯卧体位）。录像采集采用Mobius行车记录仪（Mobius dashcam），研究人员嘱咐婴儿家长于晨间启动设备，并保持录制直至存储卡存满，单次录制时长通常为10至12小时。本次采集同时涵盖了大量其他社会互动与环境互动场景。本研究旨在评估俯卧互动时间相关行为，包括延长单次俯卧互动时段的促进因素，以及提前终止该时段的阻碍因素。部分录像未启用音频采集功能，但多数录像包含音频信息。
