Table 3. Linear regressions between newborns’ average dwell time and effortful control, surgency and total behavioral difficulties score in childhood.

N = 80
Independent Variable: Average Dwell Time
Dependent Variable	B	β	t	95% CI for β Lower Bound	95% CI for β Upper Bound	R2	p-value
Effortful Control	.03	.03	.30	−.17	.23	.001	.54
Surgency	−.25	−.25	−2.24	−.49	−.02	.04	.02
Total Behavioral Difficulties	−.28	−.28	−2.09	−.55	−.01	.05	.04

Note: The “B” and “β” refer to the unstandardized and standardized regression coefficients respectively followed by the “t-statistic”. The “R²” represents the variance explained by the independent variable on the dependent variables after regressing out the effect of the covariates; finally, the p-value represents the value of statistical significance of the effect of the independent variable on the dependent variables, while keeping constant the effect of the covariates.
