Brief 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.

Detailed description

This study employed a 12-week, multicenter, prospective research design focusing on the administration of the antipsychotic medication paliperidone. Assessments were conducted at baseline, week 4, and week 12. Two widely used scales-the PANSS and PSP-were utilized to evaluate patients before and after treatment, followed by a correlation analysis of the results.

Design outcomes

Primary

MeasureTime frameDescription
the gender different in the effect of paliperidone treatment in schizophreniaThe differences were evaluated before treatment, and week 4 and week 12 after treatment.The difference of paliperidone treatment between males and females were explored at baseline, week 4, and week 12.

Secondary

MeasureTime frameDescription
The PANSS responses in schizophrenia with paliperidoneThe responses of PANSS were evaluated before the treatment, and week 4 and week 12 after treatmentThe Positive and Negative Syndrome Scale (PANSS) was utilized to evaluate the symptom improvment in individuals undergoing antipsychotic treatment. PANSS scores below 58 indicatemild symptoms, higher scores indicate more severe symptoms.
