Note: MM= antidepressant medication management; MM+CBT = antidepressant medication management plus relapse prevention cognitive-behavioral therapy; SES = socioeconomic status; CDRS-R: Children’s Depression Rating Scale-Revised. The means presented in this table are the arithmetic means; n = participants per group (total sample size 46 participants); nonwhite for the MM group = African American, Hispanic, Other (self-identified race/ethnicity), and nonwhite for the MM+CBT group = Hispanic.
Tested for differences between the MM and MM+CBT treatment groups on each demographic/clinical characteristic in a separate model.
Ten missing observations.
SES scale based on Hollingshead30 four-factor index.
Measured (at screening) before week 0.
Measured (at week 12) before randomizing to MM or MM+CBT.
Two missing observations associated with the MM group.
