Table 3.

Coefficients with standard errors, 95% CI, and P values of mixed model with ecological momentary assessment (EMA) reports of sedentary screen behaviors as the predictor at level 1 on the accelerometer-measured sedentary time and mixed model with the significant interaction between EMA-reported sedentary screen behaviors and sex (Level 1 N=2158, Level 2 N=192).

EMA-reported activity		Model 1a			Model 2a
		β (SE)	95% CI	P	β (SE)	95% CI	P
Accelerometer-measured STbwith Level 1 predictor
	EMA-reported TV, videos, or video games	8.1 (0.9)	6.3 to 9.8	<.001	8.1 (0.9)	6.3 to 9.8	<.001
Accelerometer-measured ST with Level 1 predictor adjusted for covariates at Level 2
	EMA-reported TV, videos, or video games	7.3 (0.9)	5.5 to 9.0	<.001	4.9 (1.2)	2.5 to 7.4	<.001
Accelerometer-measured ST with cross-level interaction
	EMA-reported TV, videos, or video games x sex	N/Ac	N/A	N/A	4.9 (1.8)	1.4 to 8.5	<.01

^aThe models are adjusted for sex, age, ethnicity, body mass index z-score, and weekends versus weekdays at level 2.

^bST: sedentary time.

^cN/A: not applicable.
