Assessment of protocol validity. Participants were asked to not nap during the SR or WR week of the study, but any rare naps in the data were scored and included in the measure of average 24 h sleep time. Significance is based on a one-sample Z-test of the difference between actigraphy measured average nightly sleep duration during the SR and WR treatment weeks (See Appendix Table A2), with associated Cohen’s D effect size shown. A similar result is found using a one-sample t-test.
