Note. N = 220. PSR = Psychiatric Status Rating of major depressive disorder. DEP = residual depressive symptom composite score. DAS = Dysfunctional Attitudes Scale. BHS = Beck Hopelessness Scale. IIP = Inventory of Interpersonal Problems. SAS-SR = Social Adjustment Scale—Self-report. PSR assessed weekly for 139 weeks after acute-phase CT. DEP, DAS, BHS, IIP, SOC assessed every 4 months for 32 months after acute-phase CT. Time period is months 0–8, 9–20, and 21–32 (continuation phase and years 1 and 2 of follow-up, respectively). Un/defined trajectory refers to more versus less orderly patterns of response in acute-phase CT. Analyses control receipt of non-protocol treatment, continuation-treatment group, and the interaction of continuation-treatment group with time period.
