Infant Sensor Questionnaire 1/2/3🔗

Name	Infant Sensor Questionnaire 1/2/3
Table Name	nt_ch_sens__qtn_{1|2|3}
Construct	Motor Development, Regulation (Sleep/Wake)
Study Visits	V02, V03
Type	Remote Questionnaire (Parent on Child)
Quality Control	When no survey responses were received, research assistants were contacted to confirm whether the surveys had been sent to participants as intended. The most common cause of missing responses was caregiver non-response, and less commonly due to human error (preferred contact/contact method not selected by RA) or technological malfunction.

Instrument Details🔗

The Infant Sensor Questionnaire, developed by the HBCD Workgroup, is a daily survey about infant heart rate and leg movement sensors that capture information about motor behavior, physical activity, and sleep.

The survey is sent daily over 3 days while the infant wore heart rate and leg movement sensors to capture context for the recordings. Sent automatically to primary caregivers at 24, 48, and 72 hours, the survey covered the preceding 24 hours, asking if sensors were worn consistently and gathering information on daily activities (e.g., typicality of the day; nap and sleep duration; time spent in car seat, swing, or other restraining device; time in a moving car or stroller; and leg swaddling during sleep). See Pini et al. 2024 for a full description of this measure.
