目的探讨司法精神病学鉴定中精神发育迟滞(MR)患者的犯罪学特征。方法采用自编的司法精神病学鉴定案例登记量表,对83例MR患者的犯罪学特征进行分析,并对轻度MR与中重度MR的犯罪学特征进行比较。结果MR涉嫌犯罪者中轻度MR占62.7%,中度MR占22.9%。性犯罪占37.3%,凶杀占34.7%,财产犯罪等占28.0%。犯罪动机明确者占96.1%。有犯罪史者占34.7%。轻度MR与中重度MR两组间作案预谋(χ2=11.9,P=0.001)、作案目标确定(χ2=7.531,P=0.006)、作案动机(χ2=7.920,P=0.019)、作案类型(χ2=7.855,P=0.02)有显著性差异。结论MR涉嫌犯罪者以轻度居多,犯罪类型以性犯罪及凶杀犯罪占比例较大,大多数犯罪动机明确。轻度MR组有作案预谋、作案前确定目标者明显高于中重度MR组。中重度MR作案动机为性满足者明显高于轻度MR。
