Beck自杀意念量表中文版在大学学生中应用的信效度

Reliability and validity of the Chinese version of Beck Scate for Suicide Ideation(BSI-CV) among university students

目的:评估Beck自杀意念量表中文版(BSI-CV)在大学学生匿名与署名调查中的信效度。方法:选定位于重庆市的42所大学作为调查现场,采用多阶段分层随机抽样方法抽取其中4所大学的765例大学学生,其中629例完成了自评调查。调查内容包括主动自杀意念和BSI-CV(分别评估最近一周及既往最严重时的状况)。随机安排一半学生署名、一半学生匿名接受调查。310例学生在首次调查后第5～8天完成了重测。结果:总样本最近一周和最严重时BSI-CV总分的内部一致性Cronbachα分别为0.78和0.86,匿名样本为0.74和0.88,署名样本为0.81和0.84。总样本最近一周和最严重时BSI-CV总分的重测一致性ICC分别为0.56和0.75,匿名样本为0.80和0.81,署名样本为0.41和0.69。根据主动自杀意念评估条目将被试分为有、无主动自杀意念两组,有主动自杀意念组最近一周和最严重时BSI-CV总分均高于无主动自杀意念组(均P<0.05)。结论:Beck自杀意念量表中文版在大学学生中应用的信效度良好。匿名调查时量表的重测一致性优于署名调查时。

Objective： To assess the reliability and validity of the Chinese version of the Beck Scale for Suicide Ideation （BSI-CV） among university students. Methods： A representative sample of 765 students from 4 of 42 universities in Chongqing was identified using a multi-stage random sampling method. Totally 629 （82%） of the identified students completed a self-completion questionnaire that included an independent item of past active suicidal ideation and the BSI-CV, which assessed suicidal ideation in the prior week and at the time in the past when the subject felt most depressed or most suicidal. Respondents were randomly aSsigned to fill out the questionnaire anonymously or to provide their names on the form. Three hundred and ten participants were re-administered the questionnaire 5-8 days later. Results： The Cronbach＇s alpha values, which assess internal consistency, were 0. 78 and 0. 86, respectively for the items that assess ideation in the prior week and for items that assess ideation when most depressed. The corresponding values were 0. 74 and 0. 88 for anonymous respondents, and 0. 81 and 0. 84 for those who signed the form. The test-retest reliability （ using the Intraclass Correlation Coefficient） were 0. 56 and 0. 75 for the total score in the prior week and when most depressed, respectively; 0. 80 and 0. 81 for anonymous respondents, 0.41 and 0. 69 for respondents who signed the form, respectively. The scale scores for the prior week and for when most depressed were significantly higher in respondents who independently reported prior active suicidal ideation than in those who reported no prior active ideation. Conclusion： The Chinese version of the Beck Scale for Suicide Ideation is valid and reliable when employed with university students in China. The test-retest reliability measures for anonymous respondents are greater than those of respondents who provide their names.
