Securing Personal Input From Individuals Aging with Intellectual Disability: Do Differing Methodologies Produce Equivalent Information?

Abstract

Research is limited on whether differing methodologies for facilitating personal contributions from individuals aging with intellectual disability produce equivalent knowledge outcomes. Two matched purpose-developed tools examined five quality-of-life domains. Results showed substantial variance between qualitative interview responses and Likert-scale data, and indicate validity concerns for using either methodology in isolation.
