“…For all of the antecedent measures, when there was multi-wave assessments completed, we utilized the data available at the same ages as when effortful control was assessed (age 10, 12, 14, 16, 19). 1 Seven papers from the California Families Project have examined effortful control (Atherton, Conger, Ferrer, & Robins, 2016;Atherton, Lawson, et al, in press;Atherton, Tackett, Ferrer, & Robins, 2017;Atherton, Zheng, et al, in press;Clark, Donnellan, Conger, & Robins, 2015;Robins, Donnellan, Widaman, & Conger, 2010;Taylor, Widaman, & Robins, in press). None examined the relation between any of the antecedent factors used in the present study and effortful control, with one exception.…”
