中文版家属照护认知量表的信效度评价

Reliability and Validity of the Chinese Version of Family Perception of Care Scale

目的评价中文版家属照护认知量表（FPCS）的信度和效度。方法采用便利抽样方法,选取天津市、河北省6所养老机构中去世老年人的家属为研究对象。对FPCS进行翻译,经专家咨询及小样本访谈研究修订后,形成中文版FPCS。于2014年5月—2015年4月,通过电话、邮件及面对面交流形式对去世老年人家属进行个人一般情况和中文版FPCS问卷调查。发放问卷135份,回收有效问卷125份,有效回收率为92.6%。采用探索性因子分析、Pearson相关分析及信度分析方法等共同评价中文版FPCS的信效度。结果探索性因子分析产生6个公因子,累计方差贡献率为66.232%,各条目在其相应维度上有较高的因子负荷。基础照护维度的11个条目得分与所属维度得分的相关系数为0.342～0.691,家庭支持维度的6个条目得分与所属维度得分的相关系数为0.260～0.632,交流沟通维度的6个条目得分与所属维度得分的相关系数为0.589～0.856,居住环境维度的6个条目得分与所属维度得分的相关系数为0.904～0.913（P〈0.01）。基础照护、家庭支持、交流沟通、居住环境维度得分与总量表得分的相关系数分别为0.841、0.895、0.725、0.719（P〈0.01）。总量表的Cronbach＇sα系数为0.875,各维度的Cronbach＇sα系数为0.752～0.859;总量表的折半信度系数为0.811,各维度的折半信度系数为0.695～0.823。结论中文版FPCS作为跨文化应用工具,在我国养老机构中应用证实有较好的信效度,具有较高的科学性和使用价值,但仍需在更大范围和样本中进行验证。

Objective To investigate the reliability and validity of the Chinese version of Family Perception of Care Scale（ FPCS）. Methods Using convenience sampling method,we selected the family members of elders who died in 6 nursing settings for the aged in Tianjin and Hebei Province. The Chinese version of FPCS was formed by translation and revision through expert consultation and small sample interview. From May 2014 to April 2015,surveyed on general data were collected and Chinese version of FPCS were conducted on the family members of deceased elders by phone calls,e- mails and face- to- face communication. A total of 135 questionnaires were distributed,and 125 questionnaires were returned with an effective recovery rate of 92. 6%. Exploratory factor analysis,Pearson correlation analysis and reliability analysis were conducted to evaluate the reliability and validity of the Chinese version of FPCS. Results From exploratory factor analysis,6 factors were generated with an accumulated variance contribution of 66. 232%, and each item had high factor loading of the corresponding dimension.Correlation coefficient between the scores of the 11 items of the dimension of basic care and the score of the dimension was 0. 342- 0. 691; correlation coefficient between the scores of the 6 items of the dimension of family support and the score of the dimension was 0. 260- 0. 632; correlation coefficient between the scores of the 6 items of the dimension of communication and the score of the dimension was 0. 589- 0. 856; correlation coefficient between the scores of the 2 items of the dimension of dwelling environment and the score of the dimension was 0. 904- 0. 913（ P 〈0. 01）. The correlation coefficient between basic care,family support,communication,dwelling environment and the score of the total scale was 0. 841,0. 895,0. 725 and 0. 719respectively（ P 〈0. 01）. Cronbach＇ s α of the total scale was 0. 875,and the range of Cronbach＇ s α of each dimension was0. 752- 0. 859. Split- half reliability of the total scale was 0. 811,and the range of split- half reliability of each dimension was0. 695- 0. 823. Conclusion As a tool for cross- cultural application, the Chinese version of FPCS possesses acceptable validity and reliability in the application of Chinese nursing settings for the aged and has high- level scientificity and use value,while it is still needed to be verified in a wider range and in larger samples.
