Note. Coupling refers the within-person association of cortisol with DHEA. CDP = the conflict discussion paradigm. SPP = the social performance paradigm. −2LL = log likelihood function. AIC = Akaike information criterion. BIC = Bayesian information criterion. SE = standard error.

= p < .05. N = 106 boys and 107 girls for the CDP and SPP (Study 1). N = 52 boys and 56 girls for the venipuncture (Study 2).
