卒中后失语患者抑郁问卷（医院版）在卒中后失语患者中应用的信度和效度检验

Reliability and validity tests of the Stroke Aphasic Depression Questionnaire Hospital Version in patients with poststroke aphasia

目的建立标准化的中文版卒中后失语患者抑郁问卷（医院版）（Stroke Aphasic Depression Questionnaire Hospital Version,SADQ—H），并评价其在卒中后失语患者中应用的信度和效度。方法在取得英文版卒中后失语患者抑郁问卷原作者授权同意书后，将SADQ—H修订成中文版本；以符合纳入标准的住院卒中后失语患者为试验组，以卒中后非失语患者为对照组；经过汉语失语检查法（Aphasia Battery of Chinese，ABC）评测，将试验组再分为听理解障碍组和非听理解障碍组；由经过培训的医护人员对所有患者进行SADQ—H评测，非听理解障碍组同时行Hamilton抑郁量表（Hamilton Depression Rating Scale，HAMD）和Beck抑郁问卷（Beck Depression Inventory,BDI）检查；部分患者1周后复测SADQ—H。结果信度检验显示，重测信度为0．840，内部一致性检验Cronbaehα系数为0．787；效度检验显示，效标效度为0．590（以HAMD为效标）和0．495（以BDI为效标），结构效度的因素累积方差贡献率为77.123％，区分效度为2．078。结论SADQ-H中文修订版具有良好的信度和效度，可作为中国卒中后失语患者抑郁情绪评定的有效工具。

Objective To establish a standardized stroke aphasic depression questionnaire hospital version （SADQ-H） in Chinese and to evaluate its reliability and validity in the application in patients with poststroke aphasia, Methads After acquiring the author＇s letter of attorney, we revised the English SADQ-H into Chinese version; the inpatients with poststroke aphasia who met the inclusion criteria were used as test group, and the patients without poststroke aphasia were used as control group; after evaluating the Aphasia Battery of Chinese （ABC）, the test group was redivided into an auditory comprehension disorder group and a non-anditory comprehension disorder group; and all patients were assessed with SADQ-H by the trained health care workers. The patients in the non-auditory comprehension disorder group were evaluated by the Hamilton depression rating scale （HAMD） and the Beck Depression Inventory （BDI）. SADQ-H was retested in some patients 1 week later. Results The reliability test showed that the retested reliability was 0. 840, and internal consistency reliability Cronbach＇s α coefficient was 0. 78; the validity test showed that the criterion validities were 0. 590 （HAMD as criterion） and 0. 495 （BDI as criterion）. The accumulated variance contribution rate from factors of construct validity was 77. 123%. The discriminant validity was 2. 078. Conclusions The SADQ-H in Chinese has favorable reliability and validity, and it can be used as an effective tool in the assessment of depression in patients with poststroke aphasia in China.
