目的 探讨流浪肇事肇祸精神障碍患者社会功能缺陷及危险行为,为患者的社区防治康复提供参考.方法 将在本院接受治疗的流浪精神障碍患者采用随机数字表法抽样,95例有肇事肇祸事件的患者设为研究组,121例无肇事肇祸事件的患者设为对照组.比较两组患者的病种分布及住院期间的危险行为发生率,于治疗前和治疗3个月末分别采用住院精神病人社会功能评定量表和危险度评级评定两组患者的社会功能和危险度.结果 两组患者病种分布情况比较差异无统计学意义(P＞0 .05) .研究组住院期间吵架斗殴、挑衅、骂人伤人、毁物、逃跑、自伤、偷窃、抢物、色情行为发生率显著高于对照组( P＜0 .05或0 .01) .治疗3个月末两组住院精神病人社会功能评定量表总分均显著高于治疗前(P＜0 .01) ,研究组较对照组升高更显著(P＜0 .05) .治疗前研究组危险度2级、3级、4级、5级患者所占比例显著高于对照组( P＜0 .05或0 .01) ,治疗后两组患者的危险度均有所降低,两组间比较差异无统计学意义(P＞0 .05) .结论 流浪肇事肇祸精神障碍患者存在明显社会功能缺陷和危害行为,需要采取系统治疗和康复措施,及时准确地评估危险度,并在社区中重点动态监测管控,促进患者回归社会.、Objective To investigate the social function defect and risk behavior in troublemaking home-lessness patients with mental disorders ,and provide reference for community prevention and rehabilitation of patients .Methods Patients with stray mental disorders who were treated in our hospital were sampled by random number table ,95 cases of troublemaking homelessness patients were seen as the study group , and 121 cases of non-troublemaking homelessness patients were seen as the control group .The disease type distribution and risk behavior incidence during hospitalization of the two groups were compared .The social function and risk of the two groups of patients were assessed using the SSFPI scale and risk rating before treatment and at the end of 3 months of treatment .Results There was no significant difference in the distribution of disease between the two groups (P＞0 .05).During the hospitalization period ,the inci-dence of quarrel ,provocation ,wounding others ,destruction ,escape ,self-injury ,theft ,looting ,and erot-ic behavior was significantly higher in the study group than that in the control group (P＜0 .05 or 0 .01). At the end of 3 months ,the total scores of SSFPI in the two groups were significantly higher than those before treatment (P＜0 .01) ,and the study group elevated more significantly than the control group (P＜0 .05).The proportion of patients with risk level 2 ,3 ,4 ,5 in the study group before treatment was sig-nificantly higher than that in the control group (P＜0 .05 or 0 .01).The risk of both groups was reduced after treatment ,and there was no significant difference between the two groups (P＞0 .05).Conclusion Troublemaking homelessness patients with mental disorders have obvious social function defect and dan-gerous act .Systemic treatment and rehabilitation ,timely risk assessment ,dynamic monitoring and con-trol were needed to promote patients to return to society
