Depression currently affects close to 2 million Canadians and is the leading cause of disability worldwide. Pharmacological treatments (antidepressant medication) and psychological treatments such as cognitive-behavioural therapy are available for depression, but the majority of those who receive treatment have an unsatisfactory response. On average, the combination of pharmacological and psychological treatment achieves better results than either treatment alone. However, the apparently superior results of combination treatment may be due to the fact that different individuals preferentially respond to pharmacological or psychological treatment. The invesitagtors have discovered several clinical factors and biomarkers that predict poor response to commonly used antidepressant medication: history of childhood maltreatment, loss of interest and reduced activity, a biomarker of systemic inflammation, and a genetic marker of sensitivity to environment. Indirect evidence suggests that the same factors may indicate the need for psychological treatment, but their usefulness as differential predictors of psychological and pharmacological treatment outcomes remains to be established.
The investigators will test the hypothesis that a pre-determined set of clinical variables (history of childhood maltreatment, loss of interest and reduced activity) and biomarkers (serum C-reactive protein, a marker of systemic inflammation, and short alleles of the serotonin transporter gene promoter polymorphism) differentially predicts response to antidepressants and to cognitive-behavioural psychotherapy with clinically significant accuracy.
If this hypothesis is supported, the resulting predictor will allow personalized selection of treatment for depression, leading to improved outcomes and healthcare efficiency. Additional objectives include replication of additional predictors and integrative analyses aimed at refining the treatment choice algorithms.

Cognitive Behavioral Therapy
Behavioral: Cognitive Behavioral Therapy
CBT will be delivered in a one-to-one face-to-face format by trained Masters or PhD level CBT therapists who will follow a protocol adapted from existing manuals and piloted in the participating centres. Up to 20 sessions will be offered over 18 weeks, initially twice per week, then weekly and later spaced to every other week. The treatment will have core obligatory modules and flexible elements adaptable to participant's maintaining factors.
Pharmacotherapy will be prescribed and adjusted by psychiatrists in 20-30 minute pharmacotherapy sessions once every two weeks. The manual-guided best-evidence pharmacotherapy will follow current guidelines for first, second and third line treatment.41 The primary focus will be on serotonin-reuptake inhibiting antidepressant (escitalopram 5-20mg, sertraline 50-200 mg daily) monotherapy, which may remain the only treatment for the majority of participants. Augmentation (aripiprazole 2-10mg, bupropione 150-450mg) will be offered to participants with partial response. The manual, developed as part of Canadian Biomarker Integration Network in Depression (CAN-BIND).43, also specifies admissible supportive therapeutic elements and prohibits CBT-specific techniques.
- Total score on the Montgomery Asberg Depression Rating Scale (MADRS) [ Time Frame: 2-52 weeks ]Outcomes will be measured every 2 weeks during the 18 weeks trial and at medium-term follow ups 26 and 52 weeks after the start of treatment. The primary outcome measure will be the total score on MADRS, a valid and reliable measure, sensitive to change with treatment, with a strong internal consistency and scalability.
- Global-Clinical Impression scale (GCI) [ Time Frame: 2-52 weeks ]Secondary outcome measures will include clinician-administered Global-Clinical Impression scale (GCI) administered by the treating clinician every two weeks
- Quick Inventory of Depressive Symptoms (QIDS-SR) [ Time Frame: 2-52 weeks ]Secondary outcome measures will include the Quick Inventory of Depressive Symptoms (QIDS-SR) administered by the treating clinician every two weeks
