中文版心境障碍问卷在双相Ⅱ型障碍患者中的应用

目的研究中文版心境障碍问卷（MDQ）在双相Ⅱ型障碍患者中的信度、效度等方面的应用效果。方法使用中文版MDQ对56例双相Ⅱ型障碍患者测评，其中22例患者（39．28％）在8～14d重测。结果经相关分析及Kruskal--Wallis检验，双相Ⅱ型障碍患者在接受测评时的心境状态对MDQ得分的影响无显著性意义（P值分别为0．31、0．49）。因子分析显示特征值〉1的因子有4个，特征值分别为2．85、1．82、1．63、1．58，4个因子对总方差的累积贡献率为60．6％。内部因子一致性分析MDQ全量表的Cronbach’s alpha值为0．72。MDQ重测相关系数为0．66，有显著性意义。两次测评中，MDQ中13项条目应答一致率为47．1％～88．2％。患者的MDQ得分范围为0～12分，有27例患者的MDQ得分≥7分（48．21％）。13项条目阳性回答率为23．5％～74．5％。结论中文版MDQ经在双相Ⅱ型患者中初步测试，其信度、效度基本满足心理测量学要求，可在中国患者中应用。

Reliability of Chinese Version Mood Disorder Questionnaire in patients with Bipolar II disorder

Objective To investigate the reliability and validity of the Chinese version of mood disorder questionnaire （CV--MDQ） in patients with bipolar Ⅱ disorder. Methods 56 patients with bipolar I disorder were evaluated using the CV--MDQ, and 22 patients （39.28 % ） were re--evaluated after 8 to14 days. Results There was no significant association between MDQ total scores and the subjects＇ current mental state rating （high--low）. Furthermore, the mean total MDQ scores showed no difference among sub--groups defined by the current mental state. The Eigen values of the four factors were 2.85,1.82, 1. 63,1. 58 respectively. The four factors together accounted for 60. 6% of the total variance. The Cronbach＇s alpha of the CV--MDQ was 0.72. The test--retest reliability of the MDQ was 0.66. The rate of unanimous answer of 13 items in the test--retest ranged form 47.1% to 88.6%. Patients＇ total scores ranged form 0 to 12. The MDQ scores of 27 patients （48.21%） were higher than or equal to 7. The frequency of endorsement of 13 items ranged from 23. 5% -74.5%. Conclusions The reliability and validity of the CV--MDQ in the patients with bipolar Ⅱ disorder basically meet the psychometric requests and can be used in the Chinese patients.
