think PMHx, risk factors, other conditions, symptoms
- Past history of depression
- significant physical illness or disability
- other mental health problems
- Parkinson’s disease
- Dementia
- The puerperium - prevalence around 13%

- Victims of abuse.
- Chronic pain
- Stressful home environments.
- The elderly.
- Social isolation.
- Unexplained symptoms.
Screening for depression
a) Tool : uses the DSM-IV criteria (A SAD FACES)
b) 2 initial screening Qs
c) If yes to either, 3 follow up questions

c) Management of each
a) At least 5
b) Mild - no functional impairment
- Moderate - some functional impairment
- Severe - marked functional impairment +/- psychosis
c) Mild - watchful waiting, IAPT
Mod - IAPT + antidepressant
Severe - psychiatry referral, consider ECT
When may antidepressants be considered in the context of mild depression
- If mild depression persists after other interventions, or is associated with psychosocial and medical problems.
- In mild depression complicating the care of physical health problems.
- When a patient with a history of moderate or severe depression presents with mild depression.
- With sub-threshold depressive symptoms present for at least two years or persisting after other interventions
When should moderate depression be treated with high-intensity CBT/IPT alone (rather than with antidepressant combined) ?
For an individual with a chronic health problem and moderate depression, this should be high-intensity psychological treatment alone in the first instance
