BACKGROUND
The Health of the Nation Outcome Scales for People with Learning Disabilities (HoNOS-LD) is one of the most used outcome measures in learning disability services in the United Kingdom. There is relatively little known of the psychometric properties of the scales.
METHOD
A data set of HoNOS-LD scales from 571 people with learning disabilities was randomly split into two halves. Exploratory Mokken analysis was applied to the first dataset, and confirmatory scale factor analysis was applied to the second dataset to test the fit of scale structures.
RESULTS
Two-factor and three-factor solutions were explored in the Mokken analysis, with the three-factor option having somewhat better characteristics. One-factor, three-factor and seven-factor solutions were explored using confirmatory factor analysis; a three-factor solution with items 8, 16, 17 and 18 used separately offers the best characteristics.
CONCLUSIONS
The HoNOS-LD is best conceptualised as consisting of three scales, accounting for 14 items that can be labelled as 'Cognitive and Physical Functioning', 'Behaviour and Mood Disturbances' and 'Functional Difficulties'.
背景
《学习障碍者国民健康量表（HoNOS-LD）》是英国学习障碍服务中使用最广泛的结果衡量标准之一。该量表的心理测量特性相对鲜为人知。
方法
从 571 名学习障碍者中随机抽取 HoNOS-LD 量表数据集的两半。探索性莫肯分析应用于第一个数据集，验证性量表因子分析应用于第二个数据集，以检验量表结构的拟合度。
结果
莫肯分析中探索了两因素和三因素解决方案，三因素选项具有更好的特点。使用验证性因子分析探索了单因素、三因素和七因素解决方案；单独使用包含项目 8、16、17 和 18 的三因素解决方案提供了最佳特征。
结论
HoNOS-LD 最好被概念化为由三个量表组成，共包含 14 个可标记为“认知和身体功能”、“行为和情绪障碍”和“功能障碍”的项目。
