The purpose of the study is to examine the impact of individual cognitive behavioral therapy (CBT) for adolescent depression on neural functioning. Specifically, the study will utilize Brent and Poling's (1997) cognitive behavioral therapy (CBT) manual (Cognitive Therapy Treatment Manual for Depressed and Suicidal Youth), and investigators will examine pre- to post- neural activity patterns for children and adolescents who receive individual CBT for depression. Electroencephalography (EEG) techniques will be utilized to assess treatment-related effects on brain activity (i.e., anterior cingulate cortex and dorsolateral prefrontal cortex functioning). Neural activity patterns will also be compared to non-depressed, healthy controls.
