Abstract
Background:- Better quality of life (QoL) and well-being are associated with better health and lower mortality in older adults. Promoting these concepts amongst care residents without dementia, therefore, is beneficial. Aim:- To further the understanding of QoL and well-being through the development and initial evaluation of the Care Home Measure of Quality of Life (CH-QoL); a new measure designed to evaluate the QoL and well-being of residents without dementia living in care settings. Method:- A preliminary working conceptual framework and item pool was developed through two systematic reviews. The item pool was examined for initial validity with care home residents and proxies using the Clinical Impact method. Item screening and further psychometric properties, including validity, reliability, and factor structure were evaluated with a larger sample of residents and proxies. Finally, a systematic review was conducted to understand the impact of Coronavirus disease (COVID-19) and past pandemics on QoL and well-being. Results:- An item pool was developed, consisting of seven themes, after no existing instruments were found to be theoretically or psychometrically adequate. Face and content validity were supported during the Clinical Impact study. Item screening demonstrated good initial reliability and item performance, and following exploratory factor analysis, a six-factor solution with 73 items was found. The CH-QoL's reliability was re-examined and found to be good overall. Further work to improve factor four was required, as was future research to further develop and evaluate the measure. The final review demonstrated the potential negative and long-lasting effects of the pandemic, the resilience of older adults, and the need for collecting of QoL and well-being data. Conclusion:- The CH-QoL demonstrated good psychometric properties and helped develop the theoretical understanding of QoL and well-being for residents without dementia. The knowledge can be used by researchers and care professionals to improve the lives of residents and inform future practice. Future work will allow for further refinement of the instrument.
