There are many clinical symptoms in patients with schizophrenia, among which the most common positive psychiatric symptoms are hallucinations and delusions. When clinical doctors diagnose patients with schizophrenia, they usually rely on the emotional or behavioral disorders they experience, which cannot be diagnosed through internal medicine. Due to the lack of standardized neuropathological standards for schizophrenia, it is necessary to diagnose schizophrenia patients through multiple behavioral approaches. The Positive and Negative Syndrome Scale (PANSS) can be used to analyze the mental health status and attack risk of offenders with schizophrenia in determining their criminal responsibility.

This study selected 40 offenders with defective schizophrenia as the research subjects. According to the PANSS evaluation criteria, two psychiatrists trained in PANSS were used to evaluate patients with schizophrenia.

The research results show that the PANSS score of criminal patients with schizophrenia is significantly lower than the national norm score (P<0.05). The above research results show that mandatory supervision of criminals with schizophrenia can greatly control the speed of their disease development and effectively alleviate the delay of their condition.

In summary, PANSS can effectively identify criminals with schizophrenia, help regulators effectively identify criminals with schizophrenia, and provide a reliable basis for clinical diagnosis and judicial appraisal.
