Multivariate General Linear Model showing the hypothesized overall time * group interaction^a.

Effect		𝐹	Partial Eta squared	Sig.
Between subjects	Intercept	5.600	0.463	0.000
	Age	17.056	0.724	0.000
	Group (GRS versus Comparison)	1.409	0.178	0.236
Within subjects	Time (pre versus post)	2.055	0.240	0.081
	Time * age	1.518	0.189	0.198
	Time * group	2.515	0.279	0.037

^aTo test the hypothesis that children whose parents received the GRS intervention would improve more over time relative to children whose parents received business-as-usual involvement at Head Start, a multivariate repeated measures General Linear Model was run, with scores on all six pre- and posttests entered as the dependent variables, with time entered as the within-group variable (2 levels: pre and post), with intervention group entered as the between-group variable (2 levels: intervention and comparison), and with age at pretest entered as a covariate. As predicted, a significant time * group interaction was found, suggesting that, overall, children in the intervention group improved more than children in the comparison group (𝐹 (6, 39) = 2.5; 𝑃<0.037).
