Model-estimated Parameters for Longitudinal Associations between Age 6 Diurnal Cortisol Rhythms and Age 9 CBCL Subscales

Effect	Unstandardized Estimate	SE	Est/SE	p	95% CI
					Lower	Upper
Age 9 CBCL Empirically Based Syndrome Scales, Regressed ON Age 6 Cortisol Slope
1. Attention Problems	−0.11	0.68	−0.15	0.88	−1.45	1.24
2. Rule-Breaking Behavior	1.64	0.87	1.88	0.060	−0.07	3.35
3. Aggressive Behavior	0.90	0.40	2.24	0.025	0.11	1.68
Age 9 CBCL DSM-Oriented Scales, Regressed ON Age 6 Cortisol Slope
4. AD/HD Problems	−0.17	0.60	−0.29	0.775	−1.34	1.00
5. Oppositional Defiant Problems	0.82	0.44	1.86	0.063	−0.05	1.68
6. Conduct Problems	0.93	0.44	2.12	0.034	0.07	1.80

Note. Unstandardized estimates represent the regression coefficients between age 6 cortisol slope and age 9 CBCL externalizing subscales. To obtain these estimates, two separate models were estimated, one for the empirically based syndrome scales, and one for DSM-oriented scales. All other pathways from the longitudinal model (Figure 1) were retained in these analyses, except those to internalizing behavior variables, which were non-significant in the full model. For simplicity, only the estimates between age 6 cortisol slope and age 9 externalizing subscales are presented here.
