Critical appraisal of instruments to assess illness representations in rheumatology.
A first search (MEDLINE, EMBASE, PsycINFO) identified articles describing development of instruments assessing illness representations. A second search identified articles applying them in rheumatology. Appraisal was performed using checklists.
Five instruments were identified: the Illness Perception Questionnaire (IPQ), the Revised Illness Perception Questionnaire (IPQ-R), the Illness Cognition Questionnaire (ICQ), the Implicit Models of Illness Questionnaire (IMIQ) and the Meaning of Illness Questionnaire (MIQ). The number of items varied from 18 to 70. Internal consistency was good. Construct validity was moderate to good for all instruments, but was not tested for the IMIQ. Predictive validity was assessed for the ICQ and IPQ and was low to moderate. Sensitivity to change was tested for ICQ and was good. Applications in rheumatology are increasing. Significant relationships with different outcomes and additional evidence for predictive validity were found.
Five instruments that assess illness representations can be used in rheumatology. The number of subscales and items vary. The ICQ and IPQ are most extensively validated and have been most frequently applied in rheumatology. Illness representations have relevant associations with self-report and objective outcomes. They should be considered when exploring health in rheumatology.
对评估风湿病疾病认知的工具进行批判性评价。
首次检索（MEDLINE、EMBASE、PsycINFO）确定了描述评估疾病认知工具开发的文章。二次检索确定了在风湿病领域应用这些工具的文章。使用清单进行评价。
确定了五种工具：疾病认知问卷（IPQ）、修订版疾病认知问卷（IPQ-R）、疾病认知问卷（ICQ）、疾病隐性模型问卷（IMIQ）和疾病意义问卷（MIQ）。条目数量从18条到70条不等。内部一致性良好。所有工具的结构效度为中等至良好，但未对IMIQ进行测试。对ICQ和IPQ的预测效度进行了评估，结果为低至中等。对ICQ的变化敏感性进行了测试，结果良好。在风湿病领域的应用正在增加。发现了与不同结果的显著关系以及预测效度的更多证据。
五种评估疾病认知的工具可用于风湿病领域。分量表和条目的数量各不相同。ICQ和IPQ得到了最广泛的验证，并且在风湿病领域应用最为频繁。疾病认知与自我报告和客观结果具有相关联系。在探索风湿病健康问题时应予以考虑。
