Primary Prevention of Major Depression Based on the Level and Profile of Risk of Primary Care Attenders: Cluster, Controlled, Randomised Trial (predictD-CCRT)

The main objective is to measure the effectiveness of a new intervention for primary prevention of major depression based on the level and profile of risk of primary care attendees. Among the secondary objectives is to evaluate the cost-effectiveness and cost-utility of the intervention versus usual care. METHODS: This is a cluster, randomised controlled trial of a community intervention with cluster at the level of practice. It will be undertaken in primary medical care in 7 Spanish cities and 5 autonomous communities.The aim is to evaluate a new intervention for primary prevention of major depression based on patients' level and profile of risk. Family doctors in the intervention practices will provide the intervention for patients at risk. Patients at risk who are recruited in control practices will receive usual primary care. The main outcome is the accumulated incidence of major depression (measured by CIDI) during the follow-up. The investigators will assess main outcomes and other covariables at baseline, 6, 12, and 18 months. A random sample of 3,381 primary care attendees (1,690 for each arm), aged 18-75 and without major depression will be recruited in 70 health centres (140 family doctors) in 7 cities. The investigators shall undertake a logistic regression multilevel model with 4 levels (time, patient, doctor and health centre). The investigators shall also undertake multivariate gamma and quantile regression to assess respectively the cost-effectiveness and cost-utility of the new intervention versus usual care, estimating their standard errors by bootstrap.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Psychosocial Intervention; The intervention we propose to test has 3 actives components. The first one is the fact of giving information to the GPs about the level and risk profile of depression of their patients. The second one is the transmission of this information from the GP to the patient. The third one is the interaction GP/Patient once both have the information about the risk profile of depression and the psychoeducational intervention that the GP will provide to the patient. We will develop psychoeducational booklet, DVDs and websites for patients included in the intervention group. The psychoeducative intervention will be tailored to each patient based on his/her profile, risk level and patients' risk factors. The GPs will receive a 20-hours training course in the intervention. Moreover, we will assume a communitarian view, considering the patient as an active agent for change (empowerment). That is, GPs and patients will work together in order to promote patients' resources.	Behavioral: Psychosocial Intervention; The intervention we propose to test has 3 actives components.

No Intervention: Usual Care; The kind of care that general practitioners usually provide when not knowing the level and risk profile of depression of the patients
