Feasibility of Measuring Screen Time, Activity, and Context Among Families With Preschoolers: Intensive Longitudinal Pilot Study

For convergent validity, EMA aggression was correlated with SDQ subscales of conduct problems (r=0.389; 95% CI 0.219-0.539), total difficulties (r=0.311; 95% CI 0.140-0.479), peer problems (r=0.270; 95% CI 0.092-0.439), and hyperactivity (r=0.195; 95% CI 0.013-0.372). EMA noncompliance was correlated with conduct problems (r=0.334; 95% CI 0.165-0.499) and total difficulties (r=0.247; 95% CI 0.080-0.423).

Measuring Microtemporal Processes Underlying Preschoolers’ Screen Use and Behavioral Health: Protocol for the Tots and Tech Study

However, there was only a moderate correlation between self-reported and objectively observed media use (r=0.38). Of the 49 studies that examined adults’ digital media–use behaviors, only 3 were within 5% of their objectively measured mean [10]. Another important limitation of commonly used screen time measures is their provision of global estimates of screen use, which is often gathered from a single question that asks parents to estimate television use in a typical day [14,15].
