Reliability and validity of a 3-min psychomotor vigilance task in assessing sensitivity to sleep loss and alcohol: Fitness for duty in aviation and transportation
This article reports on a study that investigated the reliability and validity of a 3-minute psychomotor vigilance task (PVT) as a strategy to assess sensitivity to sleep loss and alcohol, with implications for fitness for duty in aviation and transportation settings. The authors note that the standard 10-minute version of this screening test is impractical in most operational settings. In the present cross-over study, healthy volunteers (n = 47) followed a sleep lab protocol that included 12 consecutive days in which they experienced total sleep deprivation (38 h awake), sleep restriction (SR, 4 h sleep opportunity), acute alcohol consumption, and sleep restriction after alcohol intake (SR/Alc 4 h sleep opportunity). Participants were tested with both the 3-minute task and the 10-minute task; both measures included tasks that would be appropriate to both aviation and other modes of transportation. The results showed that sleep loss resulted in significant performance impairments, detected by both PVT versions. The authors conclude that the shorter screening test is robust, reliable, and sensitive as a tool for identifying problems in performance caused by both sleep loss and alcohol intoxication. They also briefly mention the development of a version of the 3-minute PVT task available as a smartphone app.
