More (Biased?) Results

Here are the results from the CBCL 6-18.  All of the pre-post differences were statistically significant at p<0.005:

	Girls Pre	Girls Post	Boys Pre	Boys Post	All Pre	All Post
	(n=20)	(n=20)	(n=13)	(n=13)	(n=33)	(n=33)
Internal	50.8	43.4	55.3	43.3	52.5	43.3
External	57	46.5	63.3	55.4	59.5	50
TOTAL	53.7	42.9	58.5	49.8	55.5	45.6

As one can imagine, numerous confounds and potential biases influenced these outcomes.
