Psychometric Properties of the Suicidal Ideation Questionnaire among Chinese High School Students.

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. [ABSTRACT FROM AUTHOR]
