Identifying spatial neglect - an updated systematic review of the psychometric properties of assessment tools in adults post-stroke.

Abstract

Spatial neglect commonly occurs after a stroke, resulting in diverse impacts depending on the type and severity. There are almost 300 tools for assessing neglect, yet there is a lack of knowledge on the psychometric properties of these tools. The objective of this systematic review, registered on Prospero (CRD42021271779), was to determine the quality of the evidence for assessing spatial neglect, categorized by neglect subtype. The following databases were searched on 3rd May 2022 from database inception: Ovid Emcare, Embase, Ovid MEDLINE, APA PsycINFO, Web of Science (SCI-EXPANDED; SSCI; A&HCI; ESCI) and Scopus. All primary peer-reviewed studies (>5 participants) of adults post stroke, reporting any psychometric property of 33 commonly used neglect assessment tools were included. The COSMIN (COnsensus-based Standards for the selection of health Measurement INstruments) risk of bias tool was used to assess the methodological quality of the studies and summarize the psychometric properties of each tool. 164 articles were included, with a total of 12,463 people with stroke. The general quality of the evidence was poor and no one tool had high-quality evidence of both validity and reliability. Eleven tools show some promise as they meet the minimum criteria for good measurement properties for both validity and reliability.
