Study information
Scientific title
The clinical and functional effectiveness of brief cognitive behavioural therapy compared to general practitioners care for depressive primary care patients: a randomised controlled trial
Acronym
APOLLO
Study hypothesis
Depressive disorders are highly prevalent in primary care and are associated with considerate functional impairment and increased health care use. Research has shown that many patients prefer psychological treatments to pharmacotherapy, however, it remains unclear which treatment is most optimal for depressive patients in primary care.
The aim of the trial is to compare a brief psychological therapy to general practitioners care for depression in primary care.

Intervention
General Practitioners Care:
The treatment protocol is set up according to The Dutch College of General Practitioners Practice Guideline (NHG- standard) and composed after reviewing the follow up contacts of colleague GPs with depressive patients.
Before the start of the study we will visit each participating GP and explain the treatment protocol, content of the contacts and offer a ring binder with the protocol. The description of the content of the contacts is meant as a guideline; GPs can adapt the scheme to their own style or to special circumstances. The treatment consists of supportive contacts which can be combined with an antidepressant agent. The duration of the treatment is 12 weeks. The following elements are recommended: psycho-education about depression, life style advices about sleep, alcohol/drugs, nutrition, social activities and physical activities.
The minimum frequency is one contact every two weeks during the first six weeks and one telephonic contact and one face- to- face evaluation contact during the second 6 week period. This can be increased if needed. Reasons for more contacts can be the severity of the complaints and/or lack of social support. After the first six weeks the GP evaluates, together with the patient, the need and frequency for further contacts. If recovery is not sufficient, according to the patient and/or GP, the GP will offer further contacts, during which problem solving will be a key element. If recovery is substantial the GP will provide information on relapse prevention and will offer contacts by telephone during the next month and one face-to- face contact after six weeks.
Brief Cognitive Behavioural Therapy:
The treatment will consist of 8 sessions within 12 weeks, each of fifty minutes duration. At the end of each session patients will receive homework assignments. The treatment will be directed at the role of behaviour and thinking in depressive complaints. Behaviour: patients will obtain insight in the role of pleasant activities in mood and subsequently learn to identify and expand potentially pleasant activities. Thinking: patients will obtain insight in the influence of negative thoughts and beliefs on their feelings/mood and subsequently learn to challenge these thoughts and beliefs thereby reducing the impact on their feelings. The patient learns to formulate alternative (rational) thoughts and beliefs. Eventually, the therapy will result in a personal prevention plan.
All therapists are licensed first line psychologists trained in this form of cognitive behavioural therapy. To guarantee quality, the sessions will be audio taped and the integrity of the intervention will be checked. Also, the therapist performed the intervention under supervision, which means that the therapist will regularly discuss the sessions with colleagues.
