暴力危险性评估-20对精神分裂症暴力危险性评估的信效度研究

【目的】初步探讨暴力危险性评估（HCR-20）评估精神分裂症患者暴力危险性的信效度。【方法】分别对30对有／无攻击行为的男性精神分裂症患者（攻击组／非攻击组）的简明精神病量表（BPRS）总分和各因子分、外显攻击行为量表（MOAS）总分和各因子分、Baratt冲动量表（BIS-11）总分进行测量，并对MOAS阳性组与阴性组的HCR-20总分和因子分进行比较和分析。【结果】攻击组HCR-20总分和各因子分均高于非攻击组，差异均有显著性（P〈0．01）。HCR-20与BIS-II的相关系数为0．664，与MOAS的相关系数为0．843。MOAS阳性组HCR-20总分，H因子分、C因子分、R因子分都高于阴性组，差异有显著性（P〈0．01）。BIS-11阳性组HCR-20总分，H因子分、C因子分、R因子分都高于阴性组，差异有显著性（P〈0．01）。【结论】HCR-20具有较好的信度和效度，可望用于精神分裂症患者暴力危险性评估。

Study of the Reliability and Validity of HCR-20 for Assessing Violent Risk of Patients with Schizophrenia

Objective] To explore the reliability and validity of HCR-20 for assessing the violent risk of patients with schizophrenia. Methods] The total scores of BPRS, MOAS, BIS-11, HCR-20 and the subscale scores of BPRS, MOAS, HCR-20 were Used to assess the 30 pairs of schizophrenic patients with and without aggression. The reliability and validity of HCR-20 were investigated. Results] The aggression, MOAS property aggression, auto-aggression, physical aggression subscale scores, BIS-11 total score, HCR-20 total scores and subscale scores of the study group were significantly higher than those of the control group. The correla- tion coefficient of HCR-20 and BIS-11 was 0. 664. The correlation coefficient of HCR-20 and MOAS was 0. 843. HCR-20 total scores and subscale scores of MOAS of positive group were significantly higher than those of the negative group. HCR-20 total scores and subscale scores of BIS-11 positive group were significantly higher than those of the negative group. Conclusion]The reliability and validity of HCR-20 are high. HCR- 20 can be used to evaluate the violent risk of schizophrenic patients.
