Validation of AlertMeter® Fatigue Assessment Device for Transportation Workers

The current study examined a new mobile application for the measurement of fatigue and alertness in the workplace, the AlertMeter®. Seventeen participants experienced 36-hour sleep deprivation and were measured every two hours. Sixteen of the 17 participants were able to stay awake the entire study. No adverse events were observed or reported. The AlertMeter® demonstrated strong validity as a measure of fatigue. It demonstrated significant concurrent validity with the psychomotor vigilance test (PVT) and self-ratings of fatigue (KSS). The AlertMeter® memory tests demonstrated inconsistent correlations with other measures of working memory. Overall, the AlertMeter® is an effective and valid tool for detecting fatigue in the workplace.
