Tests of bidirectional relations of TV exposure and effortful control as predictors of adjustment in early childhood in the context of family risk factors

This study examined bidirectional relations between television exposure and effortful control accounting for the effects of family contextual risk factors. Data were from a sample (N = 306) of parents and their preschool-age children (T1 M = 36 mos. in 2008-2010) assessed four times, once every 9 mos. At T1, adolescent parent status predicted lower child delay ability (DA), and maternal depression predicted higher TV time. Above these effects, higher T1 and T2 child executive control (EC) prospectively predicted lower T2 and T3 TV time, while higher T1 TV time predicted lower T2 EC. Higher EC at T4 predicted fewer total problems, greater social competence, and greater academic readiness at T4, and higher TV time at T4 predicted lower academic readiness. DA was unrelated to TV time or adjustment. Findings suggest executive control and TV time predict changes in each other in early childhood, and in turn, executive control predicts better child adjustment while TV time might be more relevant for academic readiness. Moreover, family risk factors appear to play a role in both TV viewing time and effortful control.
