Abstract:

Objective To develop an illness perception scale for gout patients，and to test its reliability and validity. Methods With the Common-Sense Model of Self-Regulation（CSM） as the conceptual framework，the initial scale was developed through literature analysis，qualitative interviews，and expert consultations. A questionnaire survey was conducted on 799 patients with gout who were treated or reviewed in a gout clinical medical center in Shandong Province from January 2021 to May 2021 to screen the items of the scale and test the reliability and validity of the scale. Results The illness perception scale for gout patients included 46 items in 6 dimensions. The exploratory factor analysis extracted 6 common factors with the cumulative variance contribution rate of 56.297%. Confirmatory factor analysis showed that the scale factor structure was stable. The item-level content validity index ranged from 0.865 to 1.000；the scale-level content validity index was 0.957. In the criterion-related validity analysis，the total score of the scale was positively correlated with the total score of the calibration scale（r=0.446，P<0.01）. The Cronbach’s alpha coefficient，split-half reliability and test-retest reliability of the scale were 0.941，0.784 and 0.965，respectively. Conclusion The illness perception scale for gout patients has good reliability and validity，which is suitable to evaluate the illness perception of gout patients.

摘要：

目的 编制痛风患者疾病感知评估量表并检验其信效度。 方法 以自我调节常识模型为理论框架，通过文献分析、质性访谈和专家函询法编制量表初稿，便利选取2021年1月—5月在山东省某痛风临床医学中心就诊的799例痛风患者进行问卷调查，筛选量表条目并检验量表信效度。 结果 痛风患者疾病感知评估量表包括6个维度、46个条目。探索性因子分析提取6个公因子，累计方差贡献率为56.297%。验证性因子分析显示，各主要评价指标均在可接受范围内。条目水平的内容效度指数为0.865~1.000，量表水平的内容效度指数为0.957。效标关联效度分析显示，量表总评分与校标量表简短疾病感知问卷得分呈正相关（r=0.446，P<0.01）。量表总的Cronbach’s α系数、折半信度、重测信度分别为0.941、0.784、0.965。 结论 痛风患者疾病感知评估量表具有良好的信效度，可用于评估痛风患者的疾病感知水平。
