Note: CDI= Child self-report score on the Children’s Depression Inventory (CDI; Kovacs, 1992); CRRST=Child self-report score on the Children’s Response Style Scale (CRRS; Ziegert & Kistner, 2002).; CRRSB=Child self-report score on the Brooding subscale of the Children’s Response Style Scale (CRRS; Ziegert & Kistner, 2002); CCSQ-C=Child self-report on tendency to catastrophize consequences of a negative event on the Children’s Cognitive Style Questionnaire (CCSQ; Abela, 2001);CCSQ-S=Child self-report on self-attributions following a negative event on the Children’s Cognitive Style Questionnaire (CCSQ; Abela, 2001); CBCL-A/D= Anxious/Depressed subscale score on the parent reported Child Behavior Checklist (CBCL; Achenbach & Rescorla, 2001); CBCL-W/D=Withdrawn/Depressed subscale score on the parent reported CBCL; CBCL-SOM=Somatic symptoms subscale on the parent reported CBCL; CBCL-INT=Internalizing subscale score on the parent reported CBCL; SCID=The Structured Clinical Interview for DSM-IV Axis I Disorders (No lifetime maternal depression diagnosis=0; Lifetime maternal depression diagnosis=1); BDIII=Parental self-report score on the Beck’s Depressive Inventory-II (BDI-II; Beck, Steer, & Brown, 1996); (SCID-I; First, Spitzer, Gibbon, & Williams, 1995); CDRS-R=Combined child self-report and parent reported scores on the Children’s Depression Rating Scale-Revised (CDRS-R; Poznanski & Mokros, 1996); SadPeak=Child’s peak pupil dilation to faces during the highest level of sadness intensity. AUC=Area Under the Curve. BCa CI=Bias-corrected accelerated confidence intervals. S=Small effect (d > .20); M=Medium effect (d> .50); L=Large Effect (d>.80). NRI=Net Reclassification Improvement Index (Pencina et al., 2012), IDI=Integrated Discrimination Index (Pencina et al., 2012); C=Multivariate AUC; H-L X2 = Hosmer-Lemeshow Test which tests whether expected rates of the outcome are significantly different than the observed rates. Non-significant p suggests the model is well-calibrated.
