Abstract:

Objective To develop and evaluate the reliability and validity of Perception of Risk of Chronic Kidney Disease Scale(PRCKDS) for patients with type 2 diabetes mellitus. Methods The item pool was determined by literature review,interview,expert consultation,and pre-investigation,and the formal scale was formed. The newly developed PRCKDS was tested on 420 patients with type 2 diabetes through an online survey. The reliability and validity of the scale were evaluated by Spearman correlation analysis,factor analysis,and Cronbach’s α respectively. Results There were 36 items in the formal scale,with 5 dimensions including susceptibility,severity,beneficence,hindrance and precipitating factors. Spearman correlation analysis indicated that the content validity was good. Confirmatory factor analysis indicated that the model fit was good. The factor loads of 36 items were all greater than 0.45 and within the preset 5 dimensions,indicating that the structure validity was good. The Cronbach’s α of homogeneity is 0.875,and the split reliability is 0.865. Conclusion The PRCKDS established in this study has good reliability and validity,and it can be used as an effective and reliable measurement tool to assess the risk perception of chronic kidney disease in patients with type 2 diabetes mellitus. Different risk perception groups should be differentiated,and individualized strategies should be adopted in the prevention education of chronic kidney disease.

摘要:

目的 编制2型糖尿病患者慢性肾脏病风险感知量表(Perception of Risk of Chronic Kidney Disease Scale,PRCKDS),并评价其信效度。 方法 以健康信念模型为理论框架,通过查阅文献、质性访谈和专家函询构建量表条目池,经专家咨询及预调查,形成预试量表,选取526例糖尿病患者对预试量表进行项目分析及因子分析后形成正式量表,并于2020年8月—12月通过网络调查收集420例糖尿病患者的有效问卷,采用Spearman 相关分析、因子分析和Cronbach’s α系数评价量表的内容效度、结构效度和信度。 结果 正式量表包括易感性、严重性、有益性、阻碍性和促发因素5个维度,共36个条目,Spearman相关系数分析显示,内容效度较好,各维度总分与同维度各条目得分间的相关系数(0.416~0.868)绝对值均大于各维度总分与其他维度各条目得分间的相关系数(-0.126~0.642),差异具有统计学意义(P<0.05)。验证性因子分析提示,正式量表模型适配度各检验量均在可接受范围内。36个条目在相应因子的载荷均>0.45且都在预设的5个维度之内,表明结构效度较好。量表的Cronbach’s α系数为0.875,分半信度为0.865。 结论 该研究构建的PRCKDS信效度良好,可作为评估2型糖尿病患者慢性肾脏病风险感知的有效、可靠测量工具。开展慢性肾脏病预防宣教时应区分不同风险感知人群并采取个性化策略。
