Note. Age and SES are included as control variables in the Spearman correlations; Higher CPT and CATA scores indicate poorer performance and higher scores on CWIT indicate better performance; sample sizes vary for some measures.

CPT=Continuous Performance Test; CATA=Continuous Auditory Test of Attention; CWIT=Color-Word Interference; CDRS= Children’s Depression Rating Scale–Revised Version; BDI=Beck Depression Inventory; BRIEF=Behavior Rating Inventory of Executive Function Global Executive Composite; QUIC=Questionnaire of Unpredictability in Childhood adolescent total score; SAS-SR-Y= Social Adjustment Scale-Self-Report for Youth; MDD=Major Depressive Disorder; HC=Healthy Control; t = Independent Samples t-test comparing MDD and HC participants.
