Note. Correlations for firstborns are below the diagonal and correlations for secondborns are above the diagonal.
T1, T2, T3, T5, T6 = Times 1, 2, 3, 5, and 6, respectively; UMO = unsupervised time with an opposite-sex peer or a peer group that includes at least one opposite-sex peer; USS = unsupervised time with a same-sex peer or peer group; SMO = supervised time with an opposite-sex peer or a peer group that includes at least one opposite-sex peer; SSS = supervised time with a same-sex peer or peer group.
Bold entries reflect correlations that are significant at p < .05.
