Abstract [en]

Purpose: In light of the research support for behavioral activation, and the promising findings of smartphone-delivered psychological interventions in the treatment of depression, we evaluated a smartphone depression application as an adjunct to four face-to-face sessions (blended treatment) for mild to moderate depression. The blended treatment was compared to a full 10-session treatment with no support from a smartphone. 

Methods: This was a non-inferiority study with unrestricted randomization in a 1:1 ratio. The study was conducted at three clinics in Sweden. 45 participants diagnosed with major depressive disorder received the blended treatment, and 43 participants received the full 10-session treatment. Main outcome measures were the BDI-II and the PHQ-9. 

Results: Results showed significant improvements in both groups across time on the primary outcome measures (within-group Cohen’s d range 1.51–1.80; between group d range −0.21– 0.01), indicating non-inferiority of the blended treatment, and at the same time with an average 44.6% reduction of therapist time. 

Conclusions: The blended treatment was non-inferior to the full behavioural treatment, and at the same time reduced therapist time. This may have important implications for planning psychological services. Moreover, from a theoretical point of view, the trial could be important as it tests the possibility to integrate modern information technology with face-to-face therapy.
