目的研究心理危机测验在研究生中应用的信度和效度。方法采用心理危机测验和自杀意念自评量表,在哈尔滨市抽取5所高等院校529名研究生进行测试。间隔3周后对其中60名研究生样本进行重测。结果总量表及5个分量表的C ronbach’α系数为0.69～0.93,3周后的重测信度为0.81～0.95。相关分析显示,心理危机测验总分与自杀意念自评量表总分相关性达到0.71(P<0.01)。验证性因素分析显示,其拟合指数分别为χ2/d f=2.60,GFI=0.76,NNFI=073,CFI=0.74,RM-SEA=0.06。结论心理危机测验在研究生中运用具有良好的信度、效度,但仍然需要在将来的研究中更深入地验证并改进其结构效度。
Objective To study the reliability and validity of psychological crisis test in graduate students. Methods A psychological crisis test and suicide ideation self-rating scale were used to test 529 postgraduates from 5 colleges and universities in Harbin. After three weeks, 60 graduate students were retested. Results The Cronbach’α coefficient of the total scale and the five subscales ranged from 0.69 to 0.93, and the test-retest reliability was 0.81 to 0.95 after 3 weeks. Correlation analysis showed that the correlation between the total score of psychological crisis test and the suicidal ideation self-rating scale reached 0.71 (P <0.01). Confirmatory factor analysis showed that the fitted indexes were χ2 / d f = 2.60, GFI = 0.76, NNFI = 073, CFI = 0.74 and RM-SEA = 0.06, respectively. Conclusions Psychological crisis test has a good reliability and validity in postgraduates. However, it still needs to verify and improve its structural validity in future research.
