痴呆患者居家老年照顾者生活质量评估量表的汉化和信效度检验

Sinicization of the Dementia Quality of Life Scale for Older Family Carers of Patients and the test of its reliability and validity

目的汉化痴呆患者居家老年照顾者生活质量评估量表并进行信效度检验。方法按照改良版的Brislin回译模型将痴呆患者居家老年照顾者生活质量评估量表翻译成中文,并对其进行文化调适,采用便利抽样法对242例痴呆患者的居家老年照顾者进行问卷调查,30 d后从中随机抽取50名照顾者重测,检验量表的信效度。结果中文版痴呆患者居家老年照顾者生活质量评估量表包括1个维度,共22个条目。量表的条目内容效度指数为0.83~1.00,全体一致内容效度指数为0.82,平均内容效度指数为0.91。量表结构模型适配指标的卡方/自由度为2.33,近似误差均方根为0.07,拟合优度指数为0.92,非规准适配指数为0.92。量表的Cronbach’sα系数为0.92,重测信度为0.81。结论中文版痴呆患者居家老年照顾者生活质量评估量表具有良好的信度和效度,可用于评估痴呆患者居家老年照顾者的生活质量,为研究者下一步减轻其负担、制订针对性的干预策略提供依据。

Objective To test the reliability and validity of Dementia Quality of Life Scale for Older Family Carers(DQoL-OC)in Chinese version.Methods According to the modified version of Brislin retranslation model,the original DQoL-OC was translated into Chinese version.The convenience sampling method was used to survey 242 older family caregivers from outpatient and inpatient patients.50 caregivers of them were randomly selected to retest after 30 days,and the data was collected to analyze the reliability and validity.Results The Chinese version of DQoL-OC contains 22 items with one dimension,which is consistent with the original scale.The I-CVI was 0.83~1.00;the S-CVI/UA was 0.82;the S-CVI/Ave was 0.91;the structure validityχ2/DF was 2.33;the approximate error mean square root(RM-SEA)was 0.07;the fitting goodness index(GFI)was 0.92,and Tucker-Lewis coefficient(TLI)was 0.92.The internal consistency index Cronbach’sαcoefficient was 0.92;the test-retest reliability was 0.81.Conclusion The Chinese version of DQoL-OC has good reliability and validity,which can be used to evaluate the quality of life of older family caregivers of dementia patients.It can provide corresponding bases for researchers to make targeted intervention strategies for the older family caregivers.
