摘要

目的检验哥伦比亚自杀筛查（CSS）在初中生自杀风险检测中的信度和有效性。方法采用方便抽样方法，对某初中902名学生进行CSS和Beck抑郁量表（BDI）测试。两周后检查Cronbachα系数、产次平分系数和重测信度。内容有效性采用专家分析和敏感性分析进行评估。BDI用于探究相关的有效性。检验了CSS和另一种自杀风险筛查方法的收敛有效性。结果有自杀问题（自杀意念或自杀未遂）的学生比例为14.97%（135/902）、14.19%（128/902）和3.66%（33/902）。CSS的Cronbachα系数和Parity分半系数分别为0.844和0.908。CSS的重测信度为自杀意念筛查（ICC=0.897）、自杀未遂筛查（ICC0.798）、物质使用筛查（ICC0.882）、自杀问题筛查（ICC 0.881），CSS的敏感性分析显示cronbachα在0.834至0.845之间。CSS与BDI的相关有效性为自杀意念筛查（ρ=0.2380.337,0.334,0.599）、自杀未遂筛查（ρ=0.022,0.231,0.310,0.221）、抑郁症筛查（ρ0.335,0.309,0.196,0.215），自杀问题筛查（ρ=0.240，0.328，0.321，0.590）和自杀问题筛查结合抑郁（ρ=0.212，0.324，0.320，0.474）（P<0.01），结论CSS具有良好的内部一致性信度、分半信度和内容有效性。自杀意念、自杀未遂、自杀问题和自杀问题合并抑郁的筛查具有良好的重测信度，但相关有效性和收敛有效性不令人满意。这四种筛查方法只能用于初中生自杀风险的初步筛查。关键词：哥伦比亚自杀屏幕；自杀；可靠性；有效性；初中生

Reliability and validity of the Columbia suicide screen in junior middle school students

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) .Cronbach's 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), screening of suicide problem (ICC=0.881), and screening of suicide problem combine depression (ICC=0.829) (P<0.01). Sensibility analysis of CSS showed the cronbach α ranged from 0.834 to 0.845.Correlative validity between CSS and BDI were screening of suicide ideation(ρ=0.238, 0.337, 0.334, 0.599), screening of suicide attempts(ρ=0.122, 0.231, 0.310, 0.221), screening of depression(ρ=0.335, 0.309, 0.196, 0.215), screening of suicide problem(ρ=0.240, 0.328, 0.321, 0.590)and screening of suicide problem combine depression(ρ=0.212, 0.324, 0.320, 0.474)(P<0.01). Convergent validity between CSS and another suicide risk screening method were screening of suicide ideation(ρ=0.468), screening of suicide attempts(ρ=0.349), screening of suicide problem(ρ=0.453), and screening of suicide problem combine depression(ρ=0.469)(P<0.01). Conclusion CSS has good internal consistency reliability, split-half reliability and content validity.Screening of suicide ideation, suicide attempts, suicide problem and suicide problem combine depression have good test-retest reliability, but the correlative validity and convergent validity are not satisfying.These four screening methods can only be used for preliminary screening suicide risk in junior middle school students.

期刊介绍： "Chinese Journal of Behavioral Medicine and Brain Science" (CN 37-1468/R, ISSN 1674-6554) is a national academic journal under the supervision of the National Health Commission, sponsored by the Chinese Medical Association and Jining Medical College. The journal was founded in June 1992 and was formerly known as "Chinese Journal of Behavioral Medicine" (1992-1993) and "Chinese Behavioral Medical Science" (1994-2008). In 2009, it was renamed "Chinese Journal of Behavioral Medicine and Brain Science" with the approval of the State Administration of Press, Publication, Radio, Film and Television. The purpose of "Chinese Journal of Behavioral Medicine and Brain Science" is to implement the health and health policies of the Party and the State, implement the principle of combining theory with practice and popularization and improvement, and reflect the major progress in the theory and practical application of behavioral medicine and brain science in my country. It publishes academic papers and scientific research results in the field of behavioral medicine and brain science in my country, and has columns such as monographs/reviews, basic research, clinical research, health prevention, methods and techniques, psychological behavior and evaluation, and systematic evaluation.
