【摘要】 目的建立痴呆生活质量量表(Dementia Quality of Life,DQoL)中文版,并检测信度和效度,以期为中国痴呆患者的生活质量测评提供有效工具。方法将DQoL翻译成中文,最终形成包括3个测试问题,29个条目,以及1项生活质量总体评价的5级量表。对简易精神状态检查量表(MMSE)筛选的40例轻中度痴呆患者进行生活质量评定,检测量表的信度和效度,并选取22例患者于4周后重测。结果 DQoL中文版Cronbach′sα系数为0.856;重测信度系数为0.726;内容效度指数(S-CVI)为0.986;量表5个维度间的相关系数为-0.133～0.694。结论 DQoL中文版具有较好的信度,效度略低,仍需扩大样本进行更深入的研究。更多还原

【Abstract】 Objective To form the Chinese version of the Dementia Quality of Life(DQoL),to evaluate its reliability and validity and to provide a valid instrument for measuring the Chinese dementia patient′s quality of life.Methods We translated the DQoL into Chinese,and produced a 5-point scale which comprised of 3 questions,29 items and 1 overall QoL item.Then,through Mini-mental State Examination(MMSE) we screened out 40 patients with mild to moderate dementia from Jinan city to evaluate DQoL′s reliability and validity.And 22 of them were retested after a 4-week interval.Results The internal consistency reliability Cronbach′s α coefficient of the Chinese version DQoL was 0.856;the test-retest correlation coefficient was 0.726;the content validity index was 0.986;the correlation coefficient among the five dimensions ranged from-0.133 to 0.694.Conclusion The Chinese version of the DQoL has good reliability but validity is slightly low,and needs further research in a larger sample.更多还原
