Smartphone-Supported versus Full Behavioural Activation for Depression: A Randomised Controlled Trial.

Area of Science:

• Clinical Psychology
• Digital Health
• Mental Health Treatment

Background:

• There is a critical need for more cost-effective and time-efficient depression treatments.
• This study introduces a novel blended treatment approach for major depression, integrating face-to-face sessions with a smartphone application.
• The trial registration number is NCT01819025.

Purpose of the Study:

• To investigate if a blended treatment (four face-to-face sessions + smartphone app) is non-inferior to a full behavioral activation (BA) treatment for depression.
• To assess the efficacy and potential cost-effectiveness of a smartphone-supported blended therapy model.

Main Methods:

• A randomized controlled non-inferiority trial comparing a blended treatment (n=46) against a full ten-session behavioral activation treatment (n=47).
• The primary outcome measure was the Beck Depression Inventory-II (BDI-II), assessed at pre-treatment, post-treatment, and six-month follow-up.
• Therapist time was recorded to evaluate efficiency.

Main Results:

• Both the blended and full BA treatment groups showed significant within-group improvements over time on the BDI-II.
• No statistically significant difference was found between the groups for the primary outcome measure, failing to establish non-inferiority.
• The blended treatment significantly reduced therapist time by an average of 47% compared to the full treatment.

Conclusions:

• While non-inferiority was not established, the blended treatment demonstrated significant symptom reduction and reduced therapist time.
• The smartphone-augmented approach has the potential to nearly double the number of depression patients treated, suggesting increased capacity.
• Further research is necessary to confirm the blended treatment as a promising, cost-effective alternative to traditional face-to-face therapy for depression.
