Ve zkratce
Blended CBT relieved depression about as well as usual face-to-face therapy in routine care. The trial followed 835 clients in nine European countries for 12 months. Blended CBT cost slightly more, so its value depends on what health systems will pay.

Context
Cognitive behavioural therapy (CBT) works well for major depression. But long waiting lists and too few trained therapists limit who can get it. The authors tested blended CBT, which combines face-to-face sessions with guided online modules. The aim is to keep therapist support while reaching more people. This was the first large trial of blended CBT for major depression in Europe. It ran in nine countries, inside ordinary primary and specialist mental health services. The comparison was treatment as usual, which was mostly face-to-face CBT. The authors asked two questions. Was blended CBT no worse than usual care? And was it good value for money?
Findings
The trial randomised 835 clients. Their average age was 39, and 67% were women. Symptoms were moderately severe at the start, with an average PHQ-9 score of 15.3. About half also had an anxiety disorder. Clients in the blended group (423) and the usual care group (412) improved substantially. The authors set a margin of d=0.20 to define "no worse". Blended CBT stayed inside that margin at every time point. During treatment, at 3 months, the difference was d=-0.26 (95% CI -0.43 to -0.09). At 6 months it was d=-0.21 (-0.39 to -0.04). At 12 months it was d=-0.01 (-0.19 to 0.17). These are small differences, slightly favouring blended CBT. At 12 months, fewer clients in the blended group still met criteria for depression (odds ratio 0.67, 95% CI 0.45-0.99). The difference for anxiety disorders was not significant (odds ratio 0.78, 95% CI 0.46-1.32). Fewer than 5% of clients in either group got worse. Clients rated the working alliance higher in blended CBT (3.97 vs 3.41 out of 5). Therapists rated it higher in usual care (4.09 vs 3.84). Both ratings indicate a strong alliance. Clients also reported higher satisfaction with blended CBT. Usability of the digital platform scored low, at 40 on a scale where 68 is average. Total health care costs were €4159 for blended CBT and €3845 for usual care. The €315 difference was not statistically significant. The authors concluded blended CBT was not cost-effective at 12 months by usual standards. The probability of good value was 0.95 at €3800 per one-point PHQ-9 improvement. It was 0.76 at €10,000 per depression case prevented.
Implications
Blended CBT gives you a workable alternative for clients with major depression. It matched face-to-face CBT on symptom change. It also slightly reduced the chance of still being depressed a year later. It may free therapist hours for other clients. Check the alliance in both directions. Clients in blended care rated it highly, but therapists rated it lower than face-to-face work. That gap may reflect comfort with familiar formats rather than client outcomes. Be honest about the limits. The 12-month result was fragile: removing one country's data made blended CBT look worse. One third of participants had dropped out by 12 months. Neither clients nor therapists were blinded, and therapist adherence to the protocol was not checked. The cost analysis was underpowered. Treat the cost findings as uncertain, not as proof of savings.
Co nepřeceňovat
Do not tell clients blended CBT is proven better than face-to-face therapy. The differences were small and mostly faded by 12 months. Do not promise cost savings; total costs were slightly higher and the difference was not significant. Do not claim strong long-term evidence; the 12-month result changed when one country's data was removed, and a third of participants had dropped out. Do not assume therapists will welcome it; in this trial they rated the alliance lower than in face-to-face care.
