Independent samples t-test of CBCL and BSI.

	Test	Statistic	df	p	Location parameter	SE difference
CBCL Total Problem Score	Student	2.791	145	0.003	6.095	2.184
CBCL Externalizing Behavior	Student	2.695	145	0.004	2.731	1.013
CBCL Internalizing Behavior	Student	4.868	145	<0.001	4.200	0.863
BSI GSI	Student	9.926	147	<0.001	36.529	3.680

For all tests, the alternative hypothesis specifies that group EG is greater than group CG. For Student’s t-test, location parameter is given by mean difference. For the Mann–Whitney test, location parameter is given by the Hodges–Lehmann estimate.

CBCL, Child Behavior Checklist; BSI, Brief Symptom Inventory; GSI, Global Severity Index; EG, experimental group; CG, control group.
