The Dynamic Psychosis-Risk Prediction (DPRP) is an online risk calculator that estimates the individual risk of transition to a manifest psychosis in patients at Clinical High Risk for Psychosis (CHR-P). The underlying joint model was developed and internally validated using the longitudinal follow-up data of the FePsy cohort.
In contrast to earlier static risk calculators, the DPRP can dynamically update its prediction as new symptom data become available during follow-up — so the prognosis becomes more accurate over time.
How to use:
- Enter the baseline data on the left (years of school education, BPRS sub-scales for positive symptoms and disorganization).
- Use Add row to add follow-up measurements of BPRS positive symptoms.
- The Figure and Table tabs show the estimated survival curve and the numeric risk estimates respectively.

Important notes
The DPRP is a research tool intended for the scientific exploration of the joint-modeling approach. It does not replace clinical assessment and should not be used as the sole basis for diagnostic or treatment decisions. Application requires that the input data (BPRS-E) were collected by trained clinicians.
