Effectiveness of a Mobile Technology Intervention for the Treatment of Depression

The study intervention has two components: the smartphone application CONEMO and primary care nurses monitoring patients' adherence to the intervention. CONEMO is a 6-week low-intensity behavior activation program delivered in 18 sessions that include messages related to the treatment goals, motivating them to do certain activities, helping to select and plan activities and messages related to psychological skills that facilitate the incorporation of activities in everyday life and to tackle obstacles that hinder patients to be more active. Primary care nurses are responsible for training participants to use the CONEMO app, monitoring patients' adherence to CONEMO, calling patients when they are non-adherent, and giving technical support when necessary.
