疾病态度量表中文版的效度和信度

Reliability and validity of the Chinese version of Illness Attitudes Scale

目的:评估疾病态度量表中文版(IAS-CV)的心理测量学特征。方法:依据ICD-10选取抑郁症、广泛性焦虑障碍、惊恐障碍、强迫症、躯体形式障碍共297例,以及正常被试212例,填写IASCV、贝克抑郁量表(BDI-Ⅱ)和贝克焦虑量表(BAI)。结果:IAS-CV的9因子结构模型拟合良好(χ~2/df=1.99,GFI=0.86,RM SEA=0.06);IAS-CV总分和BAI、BDI-Ⅱ得分呈正相关(r=0.45、0.42,P<0.01);躯体形式障碍组IAS-CV总分高于抑郁症组、其他焦虑障碍组、强迫症组和正常被试组[(62±17)vs.(43±16)、(46±21)、(46±15)、(35±13),均P<0.05]。IAS-CV的Cronbachα系数为0.91,各因子α系数为0.62~0.91;总分重测相关系数为0.95,各维度重测相关系数为0.67~0.93;IAS-CV分半系数为0.94。IAS-CV筛查躯体形式障碍的划界分为44。结论:疾病态度量表中文版(IAS-CV)具有良好的心理测量学特性,可在临床和研究工作中试用。

Objective： To test the psychometric characteristics of the Chinese Version of the Illness Attitudes Scale（IAS-CV）. Methods： Totally 297 patients （with somatoform disorders, major depressive disorder, generalized anxiety disorder, panic disorder, and obsessive-compulsive disorder diagnosed with ICD-10） and 212 normal people were assessed with IAS-CV, Beck Depression Inventory-II and Beck Anxiety Inventory. Results： The confirmation factor analysis result of the nine-factor model of IAS-CV was ,X2/df= 1.99, GFI = 0. 86, RMSEA = 0. 06. The total score of IAS-CV was correlated with BAI scores （r =0. 45, P 〈0. 01） and BDI-II seores（r =0. 42, P 〈0. 01）. Pa- tients with somatoform disorders （62 ± 17） had higher scores than patients with other disorder, such as depression （43 ± 16） , anxiety （46±21） , obsessive compulsive disorder （46 ± 15） , and normal controls （35 ＋ 13） . The Cronbach＇s a coefficients were 0. 91 for IAS-CV and 0. 62 -0. 91 for each subscale. The test-retest coefficients were 0. 95 for the total scale and 0.67 - 0. 93 for each subscale （P 〈 0. 01）. Split-half coefficient was 0.94. The cut-off score of IAS-CV for screening somatoform disorders was 44. Conclusion： It suggests that the Chinese Ver- sion of the Illness Attitudes Scale（IAS-CV） has good psychometric features and could be used in clinical practice and research in China.
