OBJECTIVES
To test the psychometric properties of the Suicidal Ideation Questionnaire (SIQ) among Chinese high school students.
METHODS
The reliability and validity of SIQ were analyzed with data of 505 high school students in Jinan, China.
RESULTS
The Cronbach's coefficient alpha of SIQ was above 0.95 and the Cronbach's coefficients alphas of SIQ when each item was deleted were relatively stable. The convergent validity analyses showed that there were statistically significant correlations between SIQ total scores and DSD total scores by gender. Exploratory factor analysis produced four factors of SIQ.
CONCLUSION
The SIQ has a high level of reliability and validity and should be a reliable measure for suicide ideation in Chinese high school students.
目的
检验自杀意念问卷（SIQ）在中国高中生中的心理测量特性。
方法
采用中国济南505名高中生的数据对SIQ的信度和效度进行分析。
结果
SIQ的克朗巴哈系数α高于0.95，各项目删除后的克朗巴哈系数α相对稳定。收敛效度分析表明，SIQ总分与按性别划分的DSD总分之间存在统计学显著相关性。探索性因素分析得出SIQ的四个因素。
结论
SIQ具有较高的信度和效度，应是测量中国高中生自杀意念的可靠工具。
