Abstract

Background: Cognitive fatigue is a complex psychobiological state whereby task performancecannot be maintained. Return-to-work protocols typically rely on self-report measures, thereforethe current systematic review aimed to identify “real-time” measures of objective cognitive fatigueto inform return-to-work protocols.Methods: Studies were included if participants were at least 18 years old, assessed “real-time”objective cognitive fatigue that could be used outside of the lab (neuroimaging measures were,therefore, excluded), used an induction task that was separate to the measurement, were ade-quately powered, compared objective cognitive fatigue at baseline and post-induction, andincluded a cognitive fatigue induction task that was at least 30 minutes long.Nine electronic databases were searched until 31 December 2022 (MEDLINE; PsychArticle;PubMED, ProQuest; ProQuest for gray literature; Google Scholar; The Cochrane Library; TheHealth Technology Assessment Database; and Web of Science), with alerts set up on GoogleScholar to notify of new relevant research since this date (reviewed until December 2023). Thechecklist for quasi-experimental studies (Joanna Briggs Institute, 2014) was used to assess the riskof bias. Whilst a meta-analysis was planned, the data were unsuitable so only a narrative synthesiswas conducted.Results: Fifty-seven studies were included, which were conducted within a variety of settingsincluding naturalistic work scenarios, driving, aviation, and artificial computer-based tasks.Whilst the review found a range of potential measurements, there were inconsistencies infindings across studies highlighting the need for more research into the reliable measurement ofobjective cognitive fatigue in natural settings.Discussion: The findings suggest that eye- and body-related measures may be sensitive measuresof objective cognitive fatigue. However, comparisons across measurement types should be cau-tiously interpreted because eye-related and cognitive measures were far more common. Thereview highlighted the need for more consistent and transparent reporting across the field toadvance our understanding of cognitive fatigue
