The aims of this study were to: further examine the content validity of the Multiple Errands Test (MET)-Home for adults with acquired brain injury (ABI), establish the inter-rater reliability and examine known groups validity.
Design : The study was done in three phases. Phase 1 involved expert review of the original MET-Home, by MET experts experienced in working with adults with ABI; Phase 2 was a single case feasibility study; Phase 3 encompassed administration of the revised MET-Home to 10 participants with ABI and 10 healthy controls matched for age, gender and education. A neuropsychological assessment including tests of attention, memory and executive functions was also administered to all participants.
Setting : Participants' homes.
Participants (or Animals, Specimens, Cadavers) :
Inclusion criteria were: age 18+; community dwelling adults; sufficient communication skills in English to answer questions and understand instructions; able to navigate independently around their home. Additional criteria for ABI participants: ABI of any severity; no mental illness not controlled by medication. Additional criterion for control participants: no history of neurological conditions.
Interventions : Not applicable.
Main Outcome Measure(s) :
The Multiple Errands Test (MET) is an assessment characterizing the effects of executive dysfunction on everyday living (Dawson et. al, 2009). The MET- Home version was developed for administration in a variety of homes, and to date, has been tested with people with stroke (Burns et al., 2018). The ubiquitous nature of executive dysfunction in those with acquired brain injury (ABI) prompted us to examine the use of the MET-Home in this population.
Results : Two tasks (an interruption task and cooking task) were added to the MET-Home to increase the complexity in line with previously published versions. The scoring guide was revised accordingly resulting in 12 tasks, 6 rules and 52 partial task failures. The single case study with a participant with severe ABI established feasibility taking 18 minutes to complete and resulting in a total error score of 12. Inter-rater reliability for the MET-Home-R (revised) was found to be high (ICCs>0.9) and known group validity demonstrated a moderate effect size difference between groups.
The MET-Home-R provides a valid, reliable and feasible way for clinicians and researchers to assess how executive dysfunction may impede daily living.
