How to rewrite this"The Positive and Negative Syndrome Scale (PANSS) is a medical scale used for measuring symptom severity in patients with schizophrenia. It assesses both positive symptoms (such as hallucinations and delusions) and negative symptoms (such as social withdrawal and lack of motivation), as well as general psychopathology. The PANSS is widely used to assess the severity of symptoms in schizophrenia. It consists of 30 items rated on a 7-point scale, covering positive, negative, and general psychopathology symptoms. According to Kaplan (1995), the PANSS is considered highly reliable and valid, with extensive evidence supporting its utility in clinical settings. Reliability: Cronbach's alpha coefficients for the PANSS range from 0.73 to 0.83, indicating strong internal consistency. Validity: Demonstrated validity through factor analyses and correlations with other symptom measures."
