Assessing the content validity of the revised Health of the Nation Outcome Scales (HoNOS 2018)
In 2014, a collaborative project was commenced to review the HoNOS. This project was led by the Royal College of Psychiatrists, as the copyright holder, with the participation of representatives from Australia and New Zealand. As a result of the review, an updated version of the HoNOS was published in 2018 and is known as the HoNOS 2018. The revisions were intended to reduce ambiguity and inconsistency in the glossary, and to promote rating consistency and clinical utility, without changing the measure’s structure. It was determined that understanding the measurement properties of HoNOS 2018 was needed to inform decisions about implementation. This is the report of a study to evaluate the content validity of the HoNOS 2018 scales.
