Does psychotherapy protect against relapse better than antidepressants alone after treatment ends?
Yes, in the sense that psychotherapy and combined treatment both outperform antidepressants alone once treatment stops. A systematic review and meta-analysis of 19 randomized controlled trials with 1,154 participants compared psychotherapy, antidepressants, and their combination in adult depression, looking at how patients fared at least 12 months after treatment ended. Combined treatment cut relapse, recurrence, and rehospitalization compared with pharmacotherapy alone (RR 0.60, 95% CI 0.37 to 0.97, p=.041), and psychotherapy alone cut relapse and recurrence compared with pharmacotherapy alone (RR 0.58, 95% CI 0.38 to 0.89, p=.023).
This is a review of enduring effects, not a test of a sequential protocol. It asks a narrower question than most depression research: what is still true a year or more after the treatment stops?
What the data show:
- Combined treatment vs medication alone: RR 0.60 (95% CI 0.37 to 0.97, p=.041) for relapse, recurrence, and rehospitalization
- Psychotherapy vs medication alone: RR 0.58 (95% CI 0.38 to 0.89, p=.023) for relapse and recurrence
- Psychotherapy vs combined treatment: comparative effects were not significant
- Study scope: 19 randomized controlled trials, 1,154 participants, all with follow-up at least 12 months after therapy ended
Across the individual trials, psychotherapy beat pharmacotherapy on relapse rates and Beck Depression Inventory scores at follow-up after acute treatment in two of nine RCTs. Combined treatment beat pharmacotherapy, though not psychotherapy, on relapse and remission in five of nine RCTs at 12 months or more after treatment stopped.
Dr. Kumar’s Take
I read this as a question about what patients carry with them after the prescription pad and the therapy hour are both behind them. Antidepressants work while you take them. The interesting claim here is that psychotherapy, alone or added to medication, leaves something behind that medication alone does not. The authors say it plainly in their conclusions: practice guidelines and shared decision-making should weigh long-term effects more heavily than they currently do. That matches what I see clinically. Patients ask me what happens when they stop, and the honest answer has to account for durability, not just acute response.
Study Snapshot
This systematic review and meta-analysis examined 19 randomized controlled trials with 1,154 participants to evaluate the enduring effects of psychotherapy, antidepressants, and their combination after treatment ends. Only RCTs in adult depression with follow-up at least 12 months after termination of therapy were included, and that therapy could be acute phase, maintenance, or relapse prevention treatment.
Results in Real Numbers
The review included 19 randomized controlled trials with a total of 1,154 participants. The authors searched PubMed and PsycInfo according to PRISMA guidelines, except for preregistration, covering trials published between 1980 and 2022. Risk of bias was assessed with the Cochrane risk of bias tool.
In the pairwise meta-analyses, combined treatment was superior to pharmacotherapy alone for relapse, recurrence, and rehospitalization rates (RR 0.60, 95% CI 0.37 to 0.97, p=.041). Psychotherapy alone was superior to pharmacotherapy alone for relapse and recurrence rates (RR 0.58, 95% CI 0.38 to 0.89, p=.023). Comparative treatment effects between psychotherapy and combined treatment were not significant, so the evidence does not separate those two options from each other.
At the level of individual trials, psychotherapy was significantly superior to pharmacotherapy on relapse rates and Beck Depression Inventory scores at follow-up after acute treatment in two of nine RCTs. Combined treatment performed significantly better than pharmacotherapy, but not better than psychotherapy, on relapse and remission in five of nine RCTs at least 12 months after treatment termination.
The authors’ conclusion is that psychotherapy and combined treatment are superior to pharmacotherapy alone in major depressive disorder, and that guidelines and participatory decision-making should give more weight to long-term effects than they do now.
Who Benefits Most
The trials enrolled adults with depression, with major depressive disorder the population the authors’ conclusion addresses. The design of this review, follow-up at least 12 months after therapy ends, makes it most relevant to anyone weighing a treatment choice with durability in mind rather than acute symptom relief alone. Depressive disorders are frequently associated with relapse, which is the reason the authors set out to look at sustained efficacy after termination in the first place.
Safety, Limits, and Caveats
The authors flag two major limitations. A low number of studies reported follow-up data after termination of the study periods. And the definitions of treatment outcomes varied across studies, so relapse, recurrence, remission, and rehospitalization do not mean exactly the same thing from trial to trial. That heterogeneity limits how tightly the pooled numbers can be read.
The comparison between psychotherapy and combined treatment was not statistically significant. Nothing here tells you that adding medication to therapy helps, or that it does not. The trials also span 1980 to 2022, a period across which both drug options and therapy protocols changed considerably.
Practical Takeaways
- If long-term protection matters to you, raise it explicitly with your psychiatrist. This review is about what holds up a year or more after treatment ends, which is a different question from what works fastest
- Psychotherapy alone and psychotherapy combined with medication both outperformed medication alone at follow-up, so both are defensible choices on the durability evidence
- The evidence does not favor combined treatment over psychotherapy alone, or the reverse
- Do not change or stop antidepressants on your own. Any change in medication belongs in a supervised plan
- Ask how outcomes were defined when you read claims about relapse prevention. In this literature the definitions vary enough to change what a result means
What This Means for Depression Treatment
The authors argue that practice guidelines and shared decision-making should account for long-term effects of antidepressant therapy methods more than they have to date. That is the practical weight of these findings: two treatment paths that include psychotherapy left patients better off than medication alone at follow-up of at least a year, in a body of evidence that rarely follows patients that far.
The counterweight is the size of that evidence base. Nineteen trials and 1,154 participants is a thin foundation for a question this consequential, and the authors say so.

FAQs
How long after treatment did these studies follow patients?
Every included trial had a follow-up point at least 12 months after therapy was terminated. That was the inclusion criterion, and it is why so few trials qualified.
Does this mean psychotherapy is better than combining it with medication?
No. The comparison between psychotherapy and combined treatment was not statistically significant. Both beat pharmacotherapy alone at follow-up, and the review does not rank them against each other.
What kind of treatment periods were included?
The therapy that preceded follow-up could be acute phase, maintenance, or relapse prevention treatment, as long as follow-up extended at least 12 months past its termination.
Bottom Line
In 19 randomized controlled trials covering 1,154 adults, psychotherapy alone and psychotherapy combined with antidepressants both produced lower relapse and recurrence rates than antidepressants alone at follow-up at least a year after treatment ended. The two psychotherapy-containing options did not differ significantly from each other. The authors’ recommendation is that guidelines and treatment decisions weigh these long-term effects more heavily than they currently do.
