Regressions of predictors on Δ short-term aggression and Δ long-term aggression

	Step		b	SE b	β
Δ Short-term PDR aggression (parent)	1	(Constant)	−5.23	1.68
		Parent training	4.37	1.18	0.49**
Δ Long-term PDR aggression (parent)	1	(Constant)	−7.49	2.06
		Parent training	3.63	1.19	0.42*
	2	(Constant)	−9.08	2.06
		Parent training	4.72	1.22	0.55**
		Cortisol/AUCi	0.35	0.15	0.34*
Δ Short-term TRF aggression (teacher)	1	(Constant)	3.89	1.63
		Cortisol/recovery	3.49	1.44	0.36*

Short-term PDR R ² for step 1 = 0.24; Long-term PDR R ² for step 1 = 0.15; R ² for step 2 = 0.26; Short-term TRF R ² for step 1 = 0.13

PDR parent daily report, TRF teacher report form, AUCi area under the curve with respect to increase, Short-term Time-1 − Time-2, Long-term Time-1 − Time-3
