Abstract

Study Objectives: The psychomotor vigilance task (PVT) is a widely used objective method to measure sustained attention, but the standard 10-min version is often impractical in operational settings. We investigated the reliability and validity of a 3-min PVT administered on a portable handheld device assessing sensitivity to sleep loss and alcohol in relation to a 10-min PVT and to applied tasks. Methods: A total of 47 healthy volunteers underwent a 12 consecutive days sleep lab protocol. A cross-over design was adopted including total sleep deprivation (38 h awake), sleep restriction (SR, 4 h sleep opportunity), acute alcohol consumption, and SR after alcohol intake (SR/Alc 4 h sleep opportunity). Participants performed a 10-min and 3-min PVT and operationally relevant tasks related to demands in aviation and transportation. Results: Sleep loss resulted in significant performance impairments compared with baseline measurements detected by both PVT versions—particularly for mean speed (both p < 0.001)—and the operationally relevant tasks. Similar effects were observed due to alcohol intake (speed: both p < 0.001). The 3-min and 10-min PVT results were highly correlated (speed: between r = 0.72 and r = 0.89). Three of four aviation-related tasks showed robust correlations with the 3-min PVT. Correlations with the parameters of the task related to transportation were lower, but mainly significant. Conclusion: The 3-min PVT showed a high reliability and validity in assessing sleep loss and alcohol-induced impairments in cognitive performance. Thus, our results underline its usefulness as potential fitness for duty self-monitoring tool in applied settings.
