简明癌症患者心理适应问卷的初步修订及信效度检验

Revision of the Chinese Version of Mini-Mental Adjustment to Cancer Scale

目的:修订简明癌症患者心理适应问卷(Mini-MAC),对其进行结构分析并进行信效度检验。方法:方便选取197名住院癌症患者填写问卷,其中52名患者在2-3周之内接受重测。采用项目分析和因素分析法对Mini-MAC量表进行分析。结果:剔除10个条目,在保留的19个条目中提取出3个因子:无助/无望(HH)、焦虑(AP)和积极态度(PA),三个因子Cronbachα系数在0.74-0.78之间,三个因子共解释总方差的46.5%。修订后总量表的Cronbachα系数为0.86,重测信度为0.49。总量表得分与住院患者焦虑与抑郁问卷、自尊量表的相关系数在0.40-0.50之间(P<0.01)。结论:Mini-MAC-19具有较好的信度和效度。

Objective： To validate the revised Chinese version of Mini-Mental Adjustment to Cancer Scale （Mini-MAC） . Methods： The psychometric properties of a Chinese version of the Mini-Mental Adjustment to Cancer Scale （Mini-MAC） were examined among 197 cancer patients in Beijing. Fifty-two patients received retest after two or three weeks. Exploratory factor analysis was used to examine factor structure of the scale. Results： Ten items were deleted as a result of the reliability analysis and factor analysis. Factor analysis suggeoted three factors： Helpless-Hopeless, Anxiety and Positive Attitude （ Cronbach＇α ranged from 0. 74 to 0. 78 ） . The new scale of 19 items had acceptable internal reliability （ Cronbach＇α = 0. 86） and test-retest reliability （ r = 0. 49 ） . Construct validities of the novel factors were shown by their correlations with HADS Anxiety and Depression scores and SES scores, which were from 0. 40 to 0. 50 （P 〈0. 01 ）, in the predicted directions. Conclusion： It suggests that the three-factor model of Mini- MAC-19 is valid in Chinese cancer patients.
