Abstract

Using data from the National Longitudinal Survey of Youth (= 1,159), this study reexamines the link between maternal reports of television viewing at ages 1 and 3 and attention problems at age 7. This work represents a reanalysis and extension of recent research suggesting young children’s television viewing causes subsequent attention problems. The nonlinear specification reveals the association between television watching and attention problems exists—if at all—only at very high levels of viewing. Adding 2 covariates to the regression model eliminated even this modest effect. The earlier findings are not robust. This study also considers whether its own findings are sensitive to unobserved confounding using fixed-effects estimation. In general, it finds no meaningful relation between television viewing and attention problems.
