The goal of this clinical trial is to compare three different treatments for depression in patients with moderate depression in General Practice, aged 18-65 years.
We wish to investigate the effect of the treatment approaches, and 171 patients will be included in the trial. The participants will be randomised to one of the following three treatments:
1. Standard treatment provided by a general practitioner (i.e. the general practitioner treats the patient as he/she would normally do, when treating a patient with depression). 2. Standard treatment provided by a psychologist in the form behavioural therapy (i.e. the psychologist treats the patient as he/she would normally do, when treating a patient with depression). 3. A step-by-step treatment plan carried out by a general practitioner. The plan includes pre-determined follow-ups and a pre-determined, structured plan for which medications to use and when to increase dose or switch medication.
The hypothesis is that a structured and step-by-step treatment approach regarding patients with depression, treated in general practice, is more effective than standard treatment provided by a general practitioner and a psychologist.
All the participants will:
1. Receive one of the three treatments for 12 weeks. 2. Have meetings with the project staff every 4 weeks (week 0, 4, 8 and 12) were rating scales will be completed, e.g. a rating scale to measure progress or deterioration in the participant's depression.
The participant must be referred to the study with a diagnosis of unipolar depressive disorder, as judge by the GP.
Severity of the depressive episode corresponding to moderate depression, as judged by the GP.
Clinical uncertainty regarding which of the treatments, medication or psychotherapy, would be the better choice in the case concerned.
Age criteria: Participants must be at least 18 years old and no more than 65 years old at the time of randomisation.
Misuse of substances that might influence the study, as judged by the investigator.
Difficulty in understanding the Danish language, as judged by the investigator.
A diagnosis of dementia.
Medical conditions that might interfere with the study outcome or safety, judged so by the investigator.

Other interventionThis is an open-label pharmacological intervention.
Treatment as usual (TAU)
Other interventionThis is a "treatment as usual" provided by a general practitioner (GP). The GP will implement a standard treatment he or she normally would use, when treating a patient with moderate depression in general practice.
Treatment as usual (TAU)
Other interventionThis is a "treatment as usual" provided by a psychologist (P). The psychologist will implement Cognitive Behavioural Therapy as the standard treatment, since this is a widely used and recognised treatment strategy for patients with depression.
