Why CHR-P matters
Clinical high risk for psychosis (CHR-P) identifies people with elevated transition risk relative to the general population. It is not a diagnosis of schizophrenia, and it does not mean any individual will inevitably develop psychosis.
Elevated risk is real — and heterogeneous
Meta-analyses of CHR-P cohorts show that cumulative transition rates are higher than in the general population, yet they vary by era, enrichment and care setting. That heterogeneity matters for how trials are designed and how results should be read.
- Fusar-Poli et al. (2012) synthesised transition outcomes across high clinical-risk samples.
- Salazar de Pablo et al. (2021) updated cumulative transition probabilities over follow-up — again with substantial between-study heterogeneity.

Risk is not destiny
Most people identified as CHR-P will not transition within typical follow-up windows. Instruments such as CAARMS (Yung et al., 2005) operationalise research eligibility; they do not equal a lifelong prognosis. Individualised enrichment work (for example Cannon et al., 2016) further shows how expected event rates change with risk profiles — useful for science, not a label for families to fear.
Why earlier intervention research still matters
There is still no broadly approved pharmacotherapy labelled to prevent psychosis in CHR-P across major markets. That gap leaves an open scientific frontier: can carefully designed studies improve symptoms and functioning earlier, and — separately powered — ever answer prevention questions honestly?
What this means for visitors
- CHR-P research is about elevated, variable risk — treat messaging that implies inevitability with scepticism.
- Other CBD studies in different populations or products are not NWPT results.
- This site does not diagnose, enrol or offer investments.
