项目摘要

This study examines subjects who rearrested during eleven years after being arrested in 1980. Their first 946 cases were not prosecuted due to a psychiatric diagnosis of mental disorder decided irresponsibility or diminished responsibility. Analysis were made about situations and factors of the repeat offenses.144 cases of 946 subjects were on criminal records in the National Police Agency in Japan. In the repeated offenses, there are some felony records including homicide.Some variables, previous guilty conviction, unstable working and living conditions, weak family relationships are important factors of their recidivism. Compared to the mentally disordered group, the control homicide group repeated various crimes three times more frequently, but they committed the felonious offenses at a similar frequency.Five variables significantly effected the rate of repeat offenses ; previous guilty conviction ; felony record in the past 10 years ; hospitalization after the previous crime within 3 months ; their victims are not relatives ; and offenders had no permanent resident.The authors found out two recidivists who committed more offenses. there were some similarities between the two ; schizophrenics who had several criminal records even before onset of schizophrenia ; alcoholic abusers with repeated offenses while under intoxication ; admitted to mental hospitals after their offenses but released relatively soon ; and alone after discharge and no house to live in, with no family to support their daily lives.111 schizophrenia cases registered as homicides were selected, and they were divided into two categories ; "mono type" and "repeat type". If the borderline of predictive probability is set at 0.50, this logistic model predicted correctly 82.7% as a whole.

这项研究调查了1980年被捕后11年内再次被捕的受试者。他们最初的946起案件没有被起诉，因为精神病诊断为精神障碍，决定不负责任或减少责任。对警察厅有犯罪记录的946人中的144人进行了重复犯罪的情况和因素分析。在累犯中，有杀人等重罪前科，有犯罪前科、工作生活条件不稳定、家庭关系脆弱等变量是其累犯的重要因素。与精神障碍组相比，对照组的重复犯罪率高出3倍，但两组的重犯罪率相差无几，影响重复犯罪率的变量有5个：有无犯罪前科、近10年内有无重犯罪记录、3个月内有无住院史、被害人是否为亲属、是否为非亲属。发现两名累犯，其犯罪情节较重。两者有一些相似之处：精神分裂症患者在发病前就有多次犯罪记录;酗酒者在醉酒期间反复犯罪;犯罪后住进精神病院，但很快就出院;出院后孤身一人，无房可住，无家可养。选择了111例登记为凶杀案的精神分裂症患者，并分为“单一型”和“重复型”两类。如果将预测概率的边界设为0.50，则该逻辑斯蒂模型总体预测正确率为82.7%。
