Note. Models 1–4 are logistic regression predicting outcomes of acute-phase cognitive therapy (A-CT) for recurrent major depressive disorder (N = 523). Models 5–8 are Cox regression survival analyses of A-CT responders’ (N = 290) relapse (over 8 months) or recurrence (over 32 months). Models controlled depressive symptom severity at study intake, age, age of depression onset, education, ethnicity, and gender; and models 5–8 also controlled continuation-phase arm (lower risk responders received no continuation treatment; higher risk responders were randomized to 8 months of cognitive therapy, or clinical management with fluoxetine or pill placebo). Effect sizes for models 1–4 and 5–8 are odds ratios and hazard ratios, respectively. CI = confidence interval.
