[What words do older people use regarding ageing and frailty: a Delphi study]

Frailty is a term widely and increasingly used in describing a condition of individuals experiencing multiple problems in one or more domains of human functioning, physical, psychological, and/or social. Frailty is a common condition among older people. Yet, it seems older people barely use this term. This study aims to answer the following research questions: which words are used in the Dutch literature and which words do older people recognize and use in describing ageing and frailty?

The method was twofold, 1) a study of Dutch grey literature and 2) a Delphi procedure. This process involved collecting terms from the literature after which the words were presented to a Delphi panel of older people (>70 years, N=30). The procedure consisted of three rounds in which the panellists were asked whether they recognized or used the terms. The panellists had the opportunity to add terms to the already existing words on the lists.

A total of 187 terms were submitted to the Delphi panel. After analysis, 69 words were retained that were recognized or used by older people. The terms were subdivided into different categories. The category frailty is not included in the final list of terms, due to the panel members' lack of regocnition and use.

This study shows which alternative terms can be used in written and oral communication about themes such as frailty and ageing with older people.
