Abstract:
Correspondence between infant actigraphy and mother-recorded diary differed significantly when receiver-operator function area under the curve, correlation, and logistic regression was calculated with and without excluding periods of external motion. External motion occurred in 40% of recording time and significantly changed activity count per epoch.
