Research papers

Research topics covered in key publications

  • Primary care population (the multi-factorial nature of depression)
  • Risk factors for depression (chronic illness, social relationships)
  • Personalised treatment (recovery and depression, the use of written plans for recovery, resilience, lay accounts, social relationships, gene-environment interactions)
  • Usual care (website use, antidepressant use, treatment allocation)
  • Risk appropriate treatments (clinical predication tool, tailored care randomised controlled trial)
  • Monitoring (general practitioner continuity, the need to monitor depression care)
  • Systems re-design.
