SSW Associate Professor Jay Unick is among the co-authors of new research published in the Journal of Pediatric Psychology. "Bidirectional Effects of Sleep and Sedentary Behavior Among Toddlers: A Dynamic Multilevel Modeling Approach" examines the bidirectional effects of objectively measured nighttime sleep and sedentary activity among toddlers.

Results suggest that, on average, nighttime sleep is a stronger predictor of subsequent sedentary behavior (compared with the reverse), and this is the case for the majority of toddlers. Findings highlight the importance of interindividual associations between sleep and sedentary activity. The present study is an example of how DSEM methods can be used to ask questions about Granger-causal cross-lagged relations between variables, both within and between individuals.
