Identification of young people in the early stages of psychosis: Validation of a checklist for use in primary care.
Preliminary analysis found that the simple checklist as originally conceived had excellent sensitivity (96%) but poor specificity (10%).
The first retained the use of all 20 checklist items and achieved sensitivity of 89% and specificity of 60%.
The second retained 6 checklist items and achieved sensitivity of 88% and specificity of 47%.
Studies seem to show that we can't prevent the transition but we can delay it. This is a good thing, allow people to develop their personality and build relationships and there does seem to be a consistency from studies.
Paul concluded his presentation by saying that it is feasible to identify people at high risk of psychosis.
