The Multiple Errands Test: A Guide for Site-Specific Version Development.

Background. The complex and real-world nature of the Multiple Errands Test (MET) makes it a valuable and increasingly popular assessment of cognitive function. However, these same qualities make its local implementation challenging. Purpose. To produce an evidence-based guide for site-specific adaptation of the MET. Method. The CAN-IMPLEMENT^© knowledge translation framework informed a structured approach to the creation of a guide to site-specific version development, informed by twenty-two published approaches to MET adaptation. Applicability of the guide was supported by a two-phase revision process, in which a site-specific hospital and community version produced from its recommendations were administered with forty-two neurologically intact participants and stakeholder feedback obtained. Findings. We offer an outline of core components which maintain the integrity of the MET, and adaptable peripheries which may be modified when required by the local setting. Implications. The proposed guide provides a systematic yet flexible guide for site-specific MET development.
