RESUMO
Objective To explore the consistency between identification diagnosis and pre-identification clinical diagnosis of patients with mental disorder undergoing forensic psychiatry identification. Methods The identification data of 1 369 appraised individuals who underwent criminal responsibility identification carried out by the Forensic Institute of Second Affiliated Hospital of Jining Medical University from 2014 to 2017 were collected retrospectively using self-designed investigation data sorting table. A comparative analysis of the mental disorder diagnosis results of expert opinion and past clinical diagnosis results was made. Results Among 1 369 appraised individuals, 964 cases （70.4%） were identified and diagnosed with mental disorder and 405 cases （29.6%） without mental disorder. Among the former, 63.3% （610 cases） were clinically diagnosed, which was higher than 43.2% （175 cases, P<0.05） in the latter. Among the various mental disorders that had been identified and diagnosed, patients with hysteria, stress, and neurosis had the highest proportion of clinical diagnoses （86.7%）, while patients with mental retardation had the lowest proportion of clinical diagnoses （9.6%）. Schizophrenia had the highest overall consistency rate of identification diagnosis and clinical diagnosis （98.4%）, while personality and behavior disorder had the lowest （33.3%）. The overall consistency rate between clinical diagnosis and identification diagnosis of the mental disorder group was 84.1%, and the Kappa value was 0.759. Compared with clinical diagnosis, the consistency rate between inpatient diagnosis and identification diagnosis was higher （85.9%, P<0.05）. Conclusion In forensic psychiatry identification that provides data of past clinical diagnosis and treatment, a high consistency between identification diagnosis and clinical diagnosis of the appraised individual who is identified and diagnosed with mental disorder exists. Clinical diagnosis （especially the inpatient diagnosis） has a relatively good reference value for forensic psychiatry identification.
