df = 62. Parent gender: mothers = −1, fathers = 1; child age coded in years. Child ID: present = 1, absent = 0. Child gender: boys = 0, girls = 1. Interclass correlation for child-referent models: internal = 0.003; stable = 0.36, and control = 0.26. Interclass correlation for parent-referent models: internal = 0.01, stable = 0.30, and control = 0.08.
