摘　　要：目的探讨初中生使用哥伦比亚自杀筛选问卷(Columbia suicide screen,CSS)的信度和效度。方法采用方便取样,对902名初中生进行CSS和Beck抑郁量表(Beck depression inventory,BDI)问卷测试,计算CSS的内部一致性系数、奇偶分半系数及2周后重测信度,专家法和敏感性分析评估内容效度,计算CSS与BDI的关联效度,检查CSS与另一种自杀风险筛查的聚合效度。结果CSS筛选出自杀问题者占14.97%(135/902),其中自杀观念者占14.19%(128/902),自杀未遂者占3.66%(33/902)。CSS总问卷的Cronbach a系数为0.844,奇偶分半系数为0.908o CSS筛选方式重测信度为:自杀观念(ICC=0.897)、自杀未遂(ICC=0.798)、物质使用(ICC=0.882)、自杀问题(ICC=0.881)及自杀问题兼抑郁(ICC=0.829)(P<0.01)o CSS敏感性分析,Cronbach a范围为0.834-0.845 o CSS筛选方式与BDI关联效度为:自杀观念(p=0.238,0.337,0.334,0.599).自杀未遂(p二0.122,0.231,0.310,0.221)、抑郁(p=0.335,0.309,0.196,0.215)、自杀问题(p=0.240,0.328,0.321,0.590)及自杀问题兼抑郁(p=0.212,0.324,0.320.0.474)(P<0.05,P<0.01)。CSS筛选方式与另一种自杀风险筛查聚合效度为:自杀观念(P=O.468)、自杀未遂(p=0.349)、自杀问题(p二0.453)及自杀问题兼抑郁(p=0.469)(P<0.01)o结论CSS具有较好的内部一致性信度、分半信度及内容效度;CSS自杀观念、自杀未遂、自杀问题、自杀问题兼抑郁筛选方式有较好的重测信度,关联效度及聚合效度一般,其对初中生自杀风险只能进行初步筛选。Objective To examine the reliability and validity of the Columbia suicide screen(CSS)in detecting suicide risk for junior middle school students.Methods Using convenient sampling,902 students of a junior middle school were tested with CSS and Beck depression inventory(BDI).Cronbachxs alpha coefficient,parity split-half coefficient and test-retest reliability were examined after two weeks.Content validity was evaluated using specialist analysis and sensibility analysis.The BDI was used to explore the correlative validity.The convergent validity of CSS and another suicide risk screening method was examined.Results The proportion of students with suicide problem(suicide ideation or suicide attempts),suicide ideation within the previous year and suicide attempts in the past were 14.97%(135/902),14.19%(128/902)and 3.66%(33/902)respectively.The Cronbach's alpha coefficient and Parity split-half coefficient of CSS were 0.844 and 0.908,respectively.The test-retest reliability of CSS were screening of suicide ideation(ICC=0.897),screening of suicide attempts(ICC=0.798),screening of substance use(ICC=0.882),screen ing of suicide problem(ICC=0.881),and screening of suicide problem combine depression(ICC=0.829)(PvO.01).Sensibility analysis of CSS showed the cronbach a ranged from 0.834 to 0.845.Correlative validity between CSS and BDI were screening of suicide ideation(p=0.238,0.337,0.334,0.599),screening of suicide attempts(p=0.122,0.231,0.310,0.221),screening of depression(p=0.335,0.309,0.196,0.215),screening of suicide problem(p=0.240,0.328,0.321,0.590)and screening of suicide problem combine depression(p=0.212,0.324,0.320,0.474)(P<O.01).Convergent validity between CSS and another suicide risk screening method were screening of suicide ideation(p=0.468),screening of suicide attempts(p=0.349),screening of suicide problem(p=0.453),and screening of suicide problem combine depression(p=0.469)(P<0.01).Conclusion CSS has good internal consistency reliability,split-half reliability and content validity.Screening of suicide ideat
