The Health of the National Outcome Scales for people with Learning Disabilities (HoNOS-LD) is a widely used Clinician Reported Outcome Measure in the UK and beyond. Over its 20-year lifespan, its psychometric properties have been frequently investigated. Multiple dimensionality reduction analyses have been published, each proposing a different latent structure.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Aim:<\/jats:title>\n                    <jats:p>To analyse a set of HoNOS-LD ratings to test its internal consistency, to identify the optimal number of latent variables, and to propose the items that group together in each domain.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>A Principal Component Analysis of 169 HoNOS-LD ratings was performed to produce an initial model. The component loadings for each HoNOS-LD item were then examined, allowing the model to be adjusted to ensure the optimal balance of statistical robustness and clinical face-validity.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>HoNOS-LD\u2019s internal consistency (18 items) was \u2018acceptable\u2019 (Cronbach\u2019s alpha\u2009=\u20090.797). On excluding three items that had no bivariate correlations with the other 15 items internal consistency rose to \u2018good\u2019 (Cronbach\u2019s alpha\u2009=\u20090.828). The final, four-component solution, using the 15 items possessed good internal reliability.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>HONOS-LD statistical properties compared favourably to the other published latent structures and adheres to the tool\u2019s rating guidance. The four-component solution offers an acceptable balance of statistical robustness and clinical face validity. It provides advantages over other models in terms of internal consistency and\/or viability for use at a national level in the UK.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/00207640251323819","type":"journal-article","created":{"date-parts":[[2025,3,12]],"date-time":"2025-03-12T07:25:37Z","timestamp":1741764337000},"page":"1078-1085","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Investigating the component structure of the Health of the Nation Outcomes Scales for people with Learning Disabilities (HoNOS-LD)"],"prefix":"10.1177","volume":"71","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1589-4054","authenticated-orcid":false,"given":"Jon","family":"Painter","sequence":"first","affiliation":[{"name":"Sheffield Hallam University, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kiran","family":"Purandare","sequence":"additional","affiliation":[{"name":"Central and Northwest London NHS Foundation Trust, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joanne","family":"McCabe","sequence":"additional","affiliation":[{"name":"University Hospital Coventry and Warwickshire, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ashok","family":"Roy","sequence":"additional","affiliation":[{"name":"Coventry and Warwickshire Partnership Trust, Birmingham, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1183-6933","authenticated-orcid":false,"given":"Rohit","family":"Shankar","sequence":"additional","affiliation":[{"name":"Cornwall Intellectual Disability Equitable Research (CIDER), Cornwall Partnership NHS Foundation Trust, Truro, UK"},{"name":"Cornwall Intellectual Disability Equitable Research (CIDER), University of Plymouth Peninsula School of Medicine, Truro, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2025,3,12]]},"reference":[{"key":"e_1_3_2_2_1","doi-asserted-by":"crossref","unstructured":"Abraham J.
