Plain English Summary
Background and study aims
Depression affects almost 7% of the population and is the most important cause of disease burden in middle- and high-income countries. Psychotherapists normally focus on events within the lifespan of a patient and examine the immediate causes of depression. Recent advances in Evolutionary Psychology, however, propose that low mood has an adaptive function. Therefore the aim of this study is to test whether interventions on the evolutionary causes of depression are beneficial for patients.
Who can participate?
Romanian-speaking adults diagnosed with increased levels of depressive symptoms are eligible to participate in this project.
What does the study involve?
The participants are randomly allocated to receive either cognitive therapy or evolutionary-driven cognitive therapy for depression. Each group undergoes 12 free one-hour therapy sessions, one session per week. The participants are evaluated psychologically at the beginning, during and at the end of treatment.
What are the possible benefits and risks of participating?
Cognitive behavioural therapy does not present known risks for the patients, most of whom will benefit from it , at least to some degree.
Where is the study run from?
This project is run from the Department of Clinical Psychology and Psychotherapy, Babes-Bolyai University (Romania).
When is the study starting and how long is it expected to run for?
The duration of the study is three years (November 2011 November 2014).
Who is funding the study?
The study is funded by the Romanian Authority for Scientific Research (Romania).

Experimental group: Evolutionary-driven cognitive therapy for depression (EB-CBT). This group receives 12 EB-CBT therapy sessions, one session per week.
Control group: Cognitive therapy for depression (CBT). This group receives 12 CBT therapy sessions, one session per week.
Primary outcome measure
1. Depressive symptomatology measured with the Beck Depression Inventory (BDI)
2. Depression diagnosis, assessed by the Structured Clinical Interview for DSM-IV (SCID).
Both primary outcomes measured at baseline, fourth, eight, 12th session, and three months after the completion of the treatment.
Secondary outcome measures
1. Perceptions about quality of life
2. Social and occupational functioning
Both secondary outcomes measured at baseline, fourth, eight, 12th session, and three months after the completion of the treatment.
