To field test the applicability of a multidimensional toolkit for geriatric rehabilitation outcomes which includes nine standardized tools. Applicability is defined as context- and population-specific pragmatic qualities of an assessment tool such as respondent and examiner burden, score distribution and format compatibility.
A sample of 48 older adults representing four diagnostic groups, as well as 26 caregivers, were assessed at home in the first month after discharge from intensive rehabilitation (T1) and 2 months later (T2). Pre-determined qualitative and quantitative applicability criteria were coded and compared at T1 and T2, as well as responsiveness.
A higher respondent burden was found for three self-report tools, as well as a ceiling effect on social functioning tools. Respondent burden, examiner burden and score distribution remained stable or diminished at T2. Format compatibility deteriorated only for the mobility test due to a higher proportion of non ambulatory participants (17%). Low to moderate associations between the tools corroborated that they were not redundant (rPearson
