New normative data and convergent validity for the MET-Home revised in English speaking neurologically healthy adults and stroke survivors

ObjectiveThe Multiple Errands Test - Home (MET-Home) is a home-based standardised assessment of executive dysfunction. We revised the MET-Home to combat low acceptability of two items. We aimed to provide normative data and psychometrically validate the new version. MethodWe compared existing data for the original MET-Home and the revised version. We accounted for covariates of age, education, mobility, disability level, stroke severity and days since stroke in comparisons. We assessed reliability and validity of the revision and provided new normative data, as well as known-group discriminability analysis. We correlated MET-Home with global cognitive functioning (Montreal Cognitive Assessment), basic functioning (Barthel Index), and instrumental activities of daily living (Nottingham Extended Activities of Daily Living scale). ResultsData (N=144) from neurologically healthy participants (n=78, n=44 revised version) and survivors of stroke (n=66, 29 revised version) were analysed. MET-Home versions were not statistically different in accuracy, omissions, or partial completions (all p>.05). MET-Home reliability was high (α=.80). The MET-Home was highly related to global cognitive functioning (r=.56, p<.001), instrumental activities of daily living (r=.46, p<.001) and basic functioning (r=.35, p<.001). New normative data were generated. Known group discriminability using normative cut offs was good and specificity of MET-Home accuracy was high (90% specificity), but sensitivity was low (30% sensitivity). ConclusionThe revised MET-Home is a newly normed and valid tool useful for clinical investigation of executive dysfunction. We encourage use of this revised MET-Home with greater participant acceptability.
