Multiple Errands Test (MET) Evaluation Summary
|What does the tool measure?||The effect of executive function deficits on everyday functioning.|
|What types of clients can the tool be used for?||The Multiple Errands Test can be used with, but is not limited to, clients with stroke.|
|Is this a screening or assessment tool?||Assessment|
|Time to administer||Baycrest MET: approximately 60 minutes (Dawson et al., 2009).|
– Multiple Errands Test (MET) (Shallice and Burgess, 1991)
– MET – Simplified Version (MET-SV) (Alderman et al., 2003)
– MET – Hospital Version (MET-HV) (Knight, Alderman & Burgess, 2002)
– Virtual MET (Rand, Rukan, Weiss & Katz, 2009)
– Baycrest MET (Dawson et al., 2009)
– Modified version of the MET-SV and MET-HV (including 3 alternate versions) (Novakovic-Agopian et al., 2011, 2012)
|Reliability|| Internal consistency
– 1 study reported adequate internal consistency of the MET-HV in a sample of patients with chronic acquired brain injury including stroke.
– No studies have examined content validity of the MET with a population of patients with stroke.
– 3 studies reported that the VMET is able to differentiate between clients with stroke vs. healthy adults, and between healthy older adults vs. healthy younger adults.
*NOTE: Correlations between the MET and other measures of everyday executive functioning and IADLs used in these studies also provide support for the ecological validity of the MET.
|Floor/Ceiling Effects||No studies have reported on the floor/ceiling effects of the MET.|
|Does the tool detect change in patients?|| Responsiveness of the MET has not been formally evaluated, however:
– 1 study used a modified version of the MET-HV and MET-SV to measure change following intervention;
– 1 study used the MET-HV and the VMET to detect change in multi-tasking skills of clients with stroke following intervention.
|Acceptability||The MET provides functional assessment of executive function as it enables clients to participate in real-world activities.|
|Feasibility||Administration of the MET requires access to a shopping area and so is not always feasible in a typical clinical setting. Some tasks may need to be adapted depending on the rehabilitation setting. Administration time can be lengthy. Ecological validity is supported.|
