目的：在这篇文章中，心理测量学性质的总兰德-36及其分量表，如单维性，差异项目功能（DIF或项目偏见），同质性和可靠性，进行了检查。研究方法：在荷兰的不同地区收集了患有三种慢性疾病（多发性硬化症（n = 448）、风湿病（n = 336）和COPD（n = 259））的人群的数据。所使用的主要技术是Mokken量表分析多项。结果：兰德-36量表各分量表均为单维度。对于“心理健康”和“一般健康感知”分量表，发现DIF对不同慢性病的一些次要指标，几乎所有分量表在所有亚群中的信度都高于0.80，而几乎所有分量表在所有亚群中的同质性都高于0.50，表明“强一维，分层量表”。结论：一般而言，兰德-36量表的分量表可用于比较不同慢性病患者。“一般健康观念”分量表的功能不如预期。
Objective: In this article, psychometric properties both of the total RAND-36 and of its subscales, such as unidimensionality, differential item functioning (DIF or item bias), homogeneity and reliabilities, are examined. Methods: The data from populations with three chronic illnesses, multiple sclerosis (n = 448), rheumatism (n = 336) and COPD (n = 259), have been collected in different parts of the Netherlands. The main technique used was Mokken scale analysis for polytomous items. Results: All subscales of the RAND-36 appeared to be unidimensional. For the sub scales 'mental health' and 'general health perceptions' some minor indications of DIF for the different chronic illnesses were found. Reliabilities of almost all subscales in all subpopulations were higher than 0.80, while the homogeneities of almost all subscales in all subpopulations were higher than 0.50, indicating 'strong unidimensional, hierarchical scales'. Conclusions: In general, the subscales of the RAND-36 can be used to compare persons with different chronic illnesses. The subscale 'general health perceptions' did not function as well as would be preferred.
