D型人格量表用于心血管病人群的信效度

Reliability and Validity of Type D Personality Scale (DS14) in Chinese Cardiac Heart Disease Population

目的:分析D型人格量表(DS14)在中国冠心病、高血压人群中使用的信、效度。方法:对82例冠心病病人、185例高血压病人及215例健康人群进行量表信、效度检验。对33例冠心病病人、66例高血压病人及81例健康人进行验证性因素分析。结果:正常人群、高血压、冠心病三组人群的Cronbach’sα系数分别是消极情感(NA)为0.88、0.86、0.87,社交压抑(SI)为0.76、0.70、0.76。探索性因素分析提取出两个因子。验证性因素分析结果:χ2/df=1.49,GFI=0.85,CFI=0.94,TLI=0.93,RMSEA=0.07。NA和SI的重测信度为0.79和0.82。D型人格的分布在不同疾病类型中没有显著性差别。结论:DS14中文版具有良好的信、效度,但是仍有进一步修改的空间。

Objective： To examine the reliability and validity of Chinese version of Type D personality Scale in Chi- nese cardiac heart disease population. Methods： A questionnaire was given to 82 patients with CHD, 185 patients with primary hypertension and 215 healthy people for exploration factor analysis, and 180 subjects were collected for confirma- tory factor analysis. Results： Our results showed a high internal consistency reliability level measured by Cronbach＇s alpha coefficients, of which NA were 0.88 for healthy people, 0.86 for hypertension people and 0.87 for CHD; and SI were 0.76 for health, 0.70 for hypertension patients, 0.76 for CHD. Factor analysis of DS14 extracted two factors. The confirma- tory factor analysis supported the two-dimension structure （x2/df= 1.49, GFI =0.85, CFI =0.94,TLI =0.93, RMSEA =0.07）. Conclusion： Chinese version of DS14 is a reliable and valid measure for assessing type D personality.
