中文版老年患者家庭照护能力量表的信效度研究

Reliability and Validity of the Chinese Version Family Care-giving Competence Scale for the Elderly

目的检验中文版老年患者家庭照护能力量表的信度和效度。方法选取于2014年1—3月入住宁夏回族自治区某三级甲等医院的高龄患者316例,并以1∶1的比例纳入其家庭照护者。采用修订的中文版老年患者家庭照护能力量表对纳入患者及其家庭照护者进行调查,并进行量表的信度和效度检验。结果修订的中文版老年患者家庭照护能力量表包括家庭照护认知能力、家庭凝聚力、家庭支援能力共3个维度,10个条目。量表的内容效度指数（CVI）为0.83,条目的内容效度指数（I-CVI）为0.84;共析出3个公因子,总贡献率为76.01%,各条目对相应公因子的载荷值为0.501~0.803;量表中家庭照护认知能力维度与家庭凝聚力维度（r=0.348,P〈0.01）、家庭照护认知能力维度与家庭支援能力维度（r=0.236,P〈0.01）、家庭凝聚力维度与家庭支援能力维度（r=0.222,P〈0.01）均呈正相关,且3个维度与量表总分间均呈正相关（r值分别为0.789、0.686、0.654,P〈0.01）。量表的Cronbach＇sα系数为0.780,各维度Cronbach＇sα系数为0.780~0.804;重测信度为0.665~0.768;分半信度为0.745~0.890。结论中文版老年患者家庭照护能力量表具有良好的信效度,可用于对老年患者家庭照护能力的测评。

Objective To test the reliability and validity of Chinese version family care- giving competence scale for the elderly.Methods We enrolled 316 patients of advanced age who were admitted into a class A grade three hospital in Ningxia Hui Autonomous Region from January to March in 2014.With a ratio of 1 ∶ 1, we included the same number of family caregivers.Using the revised Chinese version family care- giving competence scale for the elderly, we conducted survey on included patients and their family caregivers.And the test on the reliability and validity of the scale was conducted.Results The revised Chinese version of family care- giving competence scale for the elderly included three dimensions,which were cognitive competence of family caregivers,family cohesion and family support capability,and 10 items.The content validity index（ CVI）was 0.83,item content validity index（ I- CVI） was 0.84; three common factors were found out,with a total contribution rate of 76.01%,and load value of each item for corresponding common factor was 0.501 ~ 0.803; positive correlation was found between cognitive competence and family cohesion（ r = 0.348,P〈0.01）,between cognitive competence and family support capability（ r = 0.236,P〈0.01） and between family cohesion and family support capability（ r = 0.222,P〈0.01）,and the three dimensions all had positive correlation with the total score of scale（ r values were 0.789,0.686 and 0.654 respectively,P〈0.01）.The Cronbach＇s α coefficient was 0.780,and the range of Cronbach＇s α of each dimension was 0.780 ~ 0.804; the test- retest reliability was 0.665 ~ 0.768; the split- half reliability was 0.745 ~ 0.890.Conclusion Chinese version family care- giving competence scale for the elderly has well reliability and validity and can be used for the evaluation of the family care- giving competence for the elderly.
