Parent-reported child time use. (A) Activities in week prior to laboratory visit (green, less-structured; blue, structured; gray, other). (B) Typical less-structured activities (1, Never; 2, Less than once a month; 3, Once a month; 4, 2–3 times a month; 5, Once a week; 6, 2–3 times a week; 7, Daily). (C) Typical structured activities during a typical week (averaged across 4 seasons). Prior-week and typical measures of parent-reported child time use were correlated and combined into z-scored composite estimates of structured and less-structured time. For all figures, error bars indicate standard error of the mean.
