Goals: To compare the effectiveness, cost-effectiveness and cost-utility of REBT as an intervention tool with respect to the usual clinical practice in adults with a diagnosis of mild-moderate major depression in PC.

Methodology: Randomized clinical trial with control group, in people diagnosed with major depression attached to the PC. This study is carried out in 9 primary care centers in Catalonia.

The exposure variable is the assignment to the REBT psychosocial intervention group or the usual clinical practice control group.

Statistical analysis: Description of the items of the measuring instruments used per month will calculate the cost by variation of quality-adjusted life year (QALY) and the increase of associated cost-effectiveness ratio contrasting the hypothesis that this is different to 22000 € by means of t-test.

Expected results: REBT in people diagnosed with mild-moderate depression in the social work consultation of PC, will improve in the clinical control of this disorder, a lower consumption of health resources, improvement in the Quality of Life and in the user satisfaction.
