Comparison Between CSHQ and Actigraphy.Results testing the null hypothesis that there is no difference between actigraphy measurements for children whose parents did not report a problem in the corresponding behavior compared to those whose parents did report a problem. Measurements that were significantly different when the parent reported the behavior as a problem are indicated in bold italics. Following parent education, actigraphy measurements of SL and WASO were significantly different based on whether or not the parent reported a problem with sleep onset delay and night wakings (i.e. awaking more than once during the night).
