The trial included 2 week run-in, 7 week intervention, and 2 week follow-up periods. Typically developing children aged 9-12y, with weeknight sleep duration <8.5 hours were enrolled (N=97). All received sleep monitoring and performance feedback. The five candidate intervention components (<i>with their settings to which participants were randomized</i>) were: 1) sleep goal (<i>guideline-based or personalized</i>); 2) screen time reduction messaging (<i>inactive or active</i>); 3) daily routine establishing messaging (<i>inactive or active</i>); 4) chimedRxiv : the preprint server for health sciences2023.01.04.23284151https://www.ebi.ac.uk/biostudies/studies/S-EPMC9882437biostudies-literaturePromoting Sleep Duration in the Pediatric Setting Using a Mobile Health Platform: A Randomized Optimization Trial.PMC9882437Williamson AAMorales KHFiks AGJawahar AZemel BSMitchell JAJuste LVajravelu MEDinges DFfalsePromoting Sleep Duration in the Pediatric Setting Using a Mobile Health Platform: A Randomized Optimization Trial.<h4>Objective</h4>Determine the optimal combination of digital health intervention component settings that increase average sleep duration by ≥30 minutes per weeknight.<h4>Methods</h4>Optimization trial using a 2⁵ factorial design.
