Predictive Validity of the Personal and Social Performance Scale for PANSS Outcomes in Schizophrenia

Summary

The Positive and Negative Syndrome Scale (PANSS) is a widely used instrument for assessing symptom severity in schizophrenia, whereas the Personal and Social Performance Scale (PSP) provides a practical measure of functional outcomes. This study aimed to evaluate the predictive validity of the PSP for PANSS outcomes in individuals with schizophrenia. A total of 763 patients diagnosed with schizophrenia and receiving paliperidone treatment were recruited in a 12-week multicenter prospective study. Among participants with a baseline PANSS score greater than 90, those with a 12-week PSP score above 60 were more likely to achieve a reduction of more than 20% in PANSS scores, whereas those with a PSP score below 60 showed less improvement.
