Beta coefficients and 95% confidence intervals for variables included in the three tested models, along with model fit and BIC values for each model, respectively. Model 1 consists of four regressors: age, condition, age by condition and CBCL; Model 2 consists of six regressors: age, condition, age by condition, testosterone, testosterone by condition and CBCL; Model 3 consists of eight regressors: age, condition, age by condition, testosterone, testosterone by condition, PDS, PDS by condition and CBCL. PDS: Pubertal Developmental Scale, CBCL: Child Behaviour Checklist, Cl: confidence interval, BIC: Bayesian Information Criterion. N =60.
