摘　　要：目的编制简易精神症状自陈量表,并确定其判定伪装的划界分。方法以精神医学鉴定中伪装精神障碍者为研究对象,与普通精神科临床的精神疾病患者及正常人进行比较,分析3组人群在该量表的得分情况,找出伪装与非伪装的划界分,并作判别分析。结果①伪装组的总分[（14.79±3.87）分]及四个因子分均显著大于精神障碍组[（4.83±4.86）分]及正常人组[（0.50±0.87）分],精神障碍组的总分及四个因子分均显著大于正常人组（P〈0.001）。②总分大于、等于13分为判定伪装的划界分,判定的总准确率89.6%,特异度91.5%,灵敏度为79.2%。结论伪装精神症状简易自陈量表是识别伪装精神症状的有效评定工具。Objective To develop a self-report scale of brief psychopathological symptoms （SBPS）, and to find the cut-off score. Methods The subjects with malingering psychiatric symptoms in forensic psychiatry, the patients with mental disorders in general psychiatry and normal sample were tested by SBPS. To compare their differences of dimensional scores and total scores of SBPS, and to find the cut-off score of detecting feigned mental disorder. Results ①The total scores （ 14.79 ± 3.87） and four dimensional scores of SBPS in malingering group were significant higher than the that of two groups of patients（4.83 ±4.86） and normal（0.50 ±0.87）. The total scores and four dimensional scores of SBPS in the group of mental disorders were also significant higher than the normal group（ P〈 0. 001 ）. ②The cut-off of the total score was 13, and the accuracy rate,the specificity and the sensitivity of SBPS were separately 89. 6%, 91. 5% and 79. 2% for detecting feigned mental disorder. Conclusion SBPS is useful to detect the malingering psychiatric symptoms.
