目的:评价生存理由量表(RFL-C)在大学生群体中的信、效度。方法:采用分层随机抽样法,在6所高校中选取48个班级共2166名大学生完成RFL-C、贝克自杀意念等量表。随机抽取140名学生,间隔4周重测RFL-C。结果:①条目与总分的相关在0.231～0.626之间;量表的cronbachα系数在0.74～0.94之间;重测信度在0.65～0.87之间。②探索性因子分析显示,RFL-C由六因子构成,结构模型分析显示六因子模型拟合指数RMSEA=0.04,GFI=0.92,NNFI=0.94,IFI=0.94,CFI=0.94。③RFL-C总分及6个因子分与贝克自杀意念量表总分呈负相关(r=-0.34～-0.10,P<0.05)。除自杀恐惧因子、道德反对因子外,无自杀意念组的生存理由量表总分及其他因子分均高于曾经有自杀意念组、曾经有自杀行为组与现有自杀意念组得分。结论:RFL-C在大学生群体中有良好的信度、效度。
Objective: To evaluate the reliability and validity of RFL-C in college students. Methods: Stratified random sampling method was used to select 2166 college students of 48 classes in 6 colleges and universities to complete RFL-C and Baker’s suicide ideation scale. A total of 140 students were randomly selected and retested RFL-C at 4-week intervals. Results: ① The correlation between items and total score was between 0.231 and 0.626; the cronbachα coefficient of scale was between 0.74 and 0.94; and the retest reliability was between 0.65 and 0.87. (2) Exploratory factor analysis showed that RFL-C was composed of six factors. Structural model analysis showed that the fitting factors of two factors model were RMSEA = 0.04, GFI = 0.92, NNFI = 0.94, IFI = 0.94 and CFI = 0.94. ③RFL-C total score and 6 factors were negatively correlated with the total score of Baker’s suicidal ideation scale (r = -0.34 ~ -0.10, P <0.05). Except for suicide fear factor and moral opposition factor, the total score of subsistence scale and other factors in suicidal ideation group were higher than those of suicidal ideation group. There were suicide group and existing group of suicide ideation score. Conclusion: RFL-C has good reliability and validity among college students.
