Title of paper: External validation of a prognostic model to improve prediction of psychosis in primary care

Available at: https://doi.org/10.3399/BJGP.2024.0017

This paper reports the external validation of the only psychosis risk prediction algorithm to be used in primary care. External validation of prediction algorithms is essential to provide evidence of transportability i.e. that the algorithm can be used outside its training environment. This vital step for prediction algorithms is often missed.
