Continuation-phase cognitive therapy's effects on remission and recovery from depression

The authors tested the effects of continuation-phase cognitive therapy (C-CT) on remission and recovery from recurrent major depressive disorder, defined as 6 weeks and 8 months, respectively, of continuously absent or minimal symptoms. Responders to acute-phase cognitive therapy were randomized to 8 months of C-CT (n = 41) or assessment control (n = 43), and they were followed 16 additional months (R. B. Jarrett et al., 2001). Relative to controls, a few more patients in C-CT remitted (88% vs. 97%), and significantly more recovered (62% vs. 84%). All patients without remission and recovery relapsed, but most patients who remitted (60%) and who recovered (75%) did not later relapse or recur. The authors discuss the importance of defining efficacious treatment as producing remission and recovery.
