  1. Abbreviations: CBCL, Child Behavior Checklist; TRF, Teacher Report Form; ECBI, Eyberg Child Behavior Inventory; PSI, Parenting Stress Index; CRPR, Child Rearing Practices Report; VCS, Vulnerable Child Scale.
  2. aData are estimates (SE). All tests are one-sided.
  3. bRandom effects covariance structure is diagonal; repeated measures covariance structure is scaled identity.
  4. cRandom effects covariance structure is scaled identity; repeated measures covariance structure is scaled identity.
  5. dRandom effects covariance structure is scaled identity; repeated measures covariance structure is first-order autoregressive with heterogeneous variances.
