- Abstract: Objective To examine the reliability and validity of the Suicidal Behaviors Questionnaire-Revised(SBQ-R)among Chinese undergraduates and to find out cut-off score for screening the risk of suicide in clinical undergraduates.Methods A total of 488 Chinese undergraduates participated in this study.Of them,366 participants were asked to complete the Chinese version of SBQ-R,Psychache Scale,and Satisfaction with Life Scale.And 45 undergraduates were re-tested after four weeks;122 undergraduates were tested by using the Suicidality Module Section of the Mini International Neuropsychiatric Interview and the Chinese version of SBQ-R.Results ① The results showed that The Chinese version of SBQ-R had one factor with good fit indices.② The internal consistency reliability,split-half reliability,and one-month retest reliability of the total questionnaire were 0.76,0.79,and 0.93,respectively.③ The total score of the SBQ-R in Chinese was positively correlated with psychache but negatively correlated with satisfaction of life,indicating that the scale has good criterion-related validity.④ Receiver operating characteristics(ROC)curve evaluation suggested that the cut-off score was 9 in terms of identifying the clinical undergraduates at high risk of suicide.Conclusion SBQ-R is a reliable,valid,and practical instrument to measure the risk of suicide among Chinese undergraduates.SBQ-R>9 is the best cut-off value for screening for high suicide risk in China.
