Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome measure is the Beck Depression Inventory II (BDI II). The BDI II is a much used, reliable and well-validated measure for both the identification of depression severity and monitoring its clinical outcome, which has been used in many primary care studies. This will be measured at baseline and 3-monthly throughout the study period. | — |
