All trials involved cognitive-behavioral therapy (CBT).Patients who received CBT while antidepressants were tapered or discontinued were significantly less likely to experience relapse or recurrence compared with those assigned to either clinical management during tapering of antidepressants or continuation of antidepressant medication. The number needed to treat (NNT) for the CBT plus drug tapering/discontinuation group was 5 compared with an NNT of 10 among those who continued pharmacotherapy.Bottom line: Sequential integration of psychotherapy after acute treatment with pharmacotherapy may serve as an effective method in preventing relapse in adults with major depressive disorder.For the study, Guidi and colleagues analyzed 13 trials (including 1,410 participants aged 18 and older with no history of comorbid psychiatric illness)—all of which involved cognitive-behavioral therapy (CBT) after an acute-phase of pharmacotherapy. They found that patients who were randomly assigned to receive CBT while antidepressants were discontinued were significantly less likely to experience relapse or recurrence compared with those assigned to either clinical management during tapering of antidepressants or continuation of antidepressant medication. The number needed to treat (NNT)—the average number of patients who need to be treated to prevent one unfavorable health outcome—for the CBT plus drug tapering/discontinuation group was 5 compared with an NNT of 10 among those who continued pharmacotherapy, suggesting a greater advantage associated with the sequential option of drug tapering/discontinuation in preventing relapse or recurrence than with continuation of antidepressants.“The average depressed patient appears to express stronger preferences for psychotherapy than for antidepressant medications, a finding that is of considerable clinical importance given that treatment preference is a potent moderator of response to therapy,” the study authors wrote.“There is urgent need for studies comparing continuation and discontinuation of antidepressant drugs during the application of the psychotherapeutic approach in the residual phase of depressive illness,” said Guidi. “There is also a need to compare different strategies—such as psychotherapy alone, pharmacotherapy alone, and their simultaneous or sequential integration in head-to-head comparisons. The efficacy of the sequential use of other well-established psychotherapies after response to pharmacotherapy need to be tested as well.” The study was supported in part by Compagnia di San Paolo, a bank foundation in Italy. ■“The Sequential Integration of Pharmacotherapy and Psychotherapy in the Treatment of Major Depressive Disorder: A Meta-Analysis of the Sequential Model and a Critical Review of the Literature” can be accessed here.
