Plain English Summary

Background and study aims
Low-intensity psychological approaches using modern means of communication (telephones and computers) could be an effective and cost-effective option for the treatment of depression. This study will compare four different approaches.

Who can participate?
240 depressive patients from primary care centers in Spain.

What does the study involve?
Over a period of seven months, general practitioners from primary health care centers will be invited to refer patients with depressive symptoms. Different investigators will run the psychological assessment and check whether the patients are eligible. Then they will be randomly allocated to one of four groups: treatment as usual (TAU), TAU + mindfulness, TAU + healthy lifestyle, or TAU + positive affect. Patients will be assessed at the start of the study, after the treatment, 6 months and one year later.

What are the possible benefits and risks of participating?
Mindfulness, healthy lifestyle, and positive affect training has been shown to reduce intensity and frequency of symptoms in depressive patients. Due to its low intensity, no side effects are anticipated in any group.

Where is the study run from?
The lead study center is the University of Balearic Islands. The study is being run in association with University Jaume I of Castelló, University of Valencia, University of Zaragoza, and University of Málaga (Spain).
