Abstract

Objectives
：The purpose of this study was to identify characteristic Vibraimage parameters in schizophrenia spectrum and other psychotic disorders.
Methods
：This study retrospectively analyzed subjects who were referred to the National Forensic Hospital in Gongju city for psychiatric evaluation between April 2019 and October 2019. After divided into two groups; Schizophrenia Spectrum Disorders group and non-organic non-psychotic disorders group, Vibraimage parameters and MMPI-2 items were compared between the two groups. In addition, we investigated the relations between Vibraimage parameters and MMPI-2 items characteristic of schizophrenia spectrum and other psychotic disorders by using the Correlation analysis.
Results
：Compared to non-organic non-psychotic disorders group, Schizophrenia Spectrum Disorders group scored low at Aggression (t=-2.752, p=0.007), Tension (t=-2.106, p=0.039), and Suspects (t=-2.617, p=0.011); high at Neuroticism (t=4,215, p<0.001) in the Vibraimage, and the group scored comparatively high at Sc (Schizophrenia) (t=-2.099, p=0.039) and low at Hy (Hysteria) (t=-2.228, p=0.029) in the MMPI-2. The Sc (Schizophrenia) item in the MMPI-2 showed a negative correlation with Suspect parameter (r=0.242 p=0.035) and positive correlation with Neuroticism parameter (r=0.267, p=0.02) in the Vibraimage.
Conclusion
：Our findings suggest that Suspect and Neuroticism parameters of the Vibraimage were characteristic in schizophrenia spectrum and other psychotic disorders, and showed potential as diagnostic tools, especially in psychiatric evaluations.
