Table 2.

Number of symptoms by age-of-onset grouping.

Symptom count variable	No CD		Adolescence-limited (AL)		Life Course Persistent (LCP)
Symptom count variable	Mean	SD	Mean	SD	Mean	SD
AGG, age 11	0.36	0.62	0.59	0.63	2.02	1.29
RB, age 11	0.22	0.46	0.38	0.48	1.49	1.03
AGG, age 17	0.34	0.65	0.89	1.00	1.27	1.48
RB, age 17	0.35	0.61	1.19	1.10	2.11	1.70
AAB, age 24	1.37	1.05	2.24	1.43	3.09	1.77
ASPD diagnosis at age 24	0.5%	--	15.5%	--	54.2%	--

Note. Statistical comparisons of the means were conducted on the log-transformed data, as they better approximate normality. However, the corresponding raw symptom counts are presented in here and discussed in the text to promote ease of understanding. The percentage of individuals meeting full diagnostic criteria for ASPD (i.e., as defined via a definite diagnosis of CD at 11 and/or 14 and a “definite diagnosis” of AAB at age 24) is also presented. All possible pairings of means within a row differed significantly from one another at p < .05, respectively.
