4 = contributing environmental or psychosocial factors
5 = global assessment of functioning
Is the multiaxial diagnosis still in use
No, DSM V removed it but it’s still useful (was in DSM IV)
List features of the biopsychosocial models
Biological, psychological, social
Predisposing, precipitating and perpetuating features
Describe the psych patient journey
Mild mental illness would go to GP - managed by GP/counselling
Moderate to severe illness who can engage and are a manageable risk would go to hospital/picked up by police - managed by GP/community mental health services/secondary care
Severe illness with significant risk would be picked up by social services - managed in ‘ward in the community’ or at home treatment / psychiatric ward (voluntary or sectioned)
