Survey data

In addition to the wearable sensor data, daily survey about infant heart rate sensor and infant leg movement sensors was collected. The survey was sent to primary caregiver once per day for 3 days during the 72 hour data collection of infant hear rate sensor data and infant leg movement sensor data.
Surveys were automatically sent via email or text message (per caregiver preference) at 10 am eastern / 9 am central / 8 am mountain / 7 am pacific.
The surveys were sent after the sensors had been recording for 24, 48, and 72 hours. The survey asked about the preceding 24-hour period. It asked whether the sensors were worn for most of the time and about the daily activities of the infant (whether or not it was a fairly typical 24 hours for the infant, estimates of how much they napped and slept, how much they were in a car seat, swing or other restraining device, how much they were in a moving car or stroller or being carried, and whether or not their legs are swaddled during naps and sleep). This survey was created by the workgroup.

A research assistant (RA) marked preferred contact and preferred method of contact (email or text message) at visit, then surveys were sent automatically. Surveys were provided in Spanish or English per family preference.

Survey data collection occurred at V02 (0-1 months of age) and at V03 (3-8 months of age).

Quality Control (QC) Processes

  • QC Procedures: Surveys were spot-checked during the data collection time frame. Only a small percentage of surveys were randomly checked each week as the process was manual. When checked, surveys were checked for the presence of response. When no response were provided, RA’s were contacted to confirm whether or not surveys had gone out to the participants as intended.

  • Common Issues Identified: Common issues identified during the QC proceeses included surveys that had no responses. Sometimes this was human error (preferred contact or prefereed method of communication not selected by RA) or potentially technological malfunction, and sometimes it was caregiver non-response. Caregiver non-response was the reason for the majority of the surveys without responses. Caregiver non-response was common. Please consider that occurrence of caregiver non-response may not be randomly distributed across the sample.
