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. ③The 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.
ABSTRACT
【Objective】 To explore the relationship between perceived stress and suicidal ideation as well as the mediating effect of resilience and depression. 【Methods】 A sample of 875 college students was recruited for the study to complete a set of self-report measures of Chinese Perceived Stress Scale (CPSS), the Resiliency Scale of University Students, Suicidal Ideation Questionnaire, and Beck Depression Inventory (BDI). 【Results】 ①College students’ perceived stress and depression had significantly positive correlation with their suicidal ideation, while the students’ resilience had a significantly negative correlation with their perceived stress and depression. ②Perceived stress did not affect suicidal ideation of the college students directly, but indirectly affected their suicidal ideation through three significant mediating pathways: the separate mediating effects of (a) resilience and (b) depression, and the serial mediating effect of (c) resilience and depression. 【Conclusion】 Resilience and depression exert a chain mediating effect between perceived stress and suicidal ideation of college students.
ABSTRACT
【Objective】 To revise the Social Connectedness Scale-Revised （SCS-R） so as to explore the factor structure of SCS-R in the context of Chinese culture and test its reliability and validity. 【Methods】 Totally 900 college students were asked to complete the Chinese version of the Social Connectedness， and 850 valid questionnaires were collected. In addition， the Distress Disclosure scale （DDI） and UCLA Loneliness Scale were used as the criteria. One month later， 100 students were randomly selected for retest. 【Results】 ① The results of exploratory factor analysis showed that one factor with more than one eigenvalue was selected， and the cumulative variance explained was 62.44%. ② Confirmatory factor analysis showed that the data fit well （χ2=33.438， df=14， χ2/df=2.388， RMSEA=0.04， CFI=0.996， TLI=0.991）. ③ The Chinese version of the social connectedness scale is a one-dimensional scale. Its internal consistency coefficient is 0.916 and test-retest reliability is 0.845. ④ Social connectedness is significantly positively correlated with distress disclosure and negatively correlated with loneliness， indicating that the scale has good criterion-related validity. 【Conclusion】 The Chinese version of the social connectedness scale has satisfactory reliability and validity， and has cross-cultural adaptability.
