Assessing the Convergent Validity of the 3- and 5-Minute Psychomotor Vigilance Tasks in Occupational Settings
SessionPoster Session 2
DescriptionThe 10-minute Psychomotor Vigilance Task (PVT-10) has been the gold standard to assess sustained attention. The PVT-10 may be challenging in certain settings, hence shorter PVTs may be required. This study assessed the convergent validity of three- (PVT-3), five-PVT (PVT-5) and PVT-10 across multiple days in a naturalistic setting using repeated measures correlations. PVT-10 data was gathered from a sample of 70 offshore workers on consecutive workdays and the shorter PVTs were extracted from PVT-10. There were strong correlations for minor PVT score probability, minor lapse probability, minor PVT score, minor lapses, median reaction time, mean response speed, mean reaction times, major lapse probability, major lapses, major PVT score probability and slowest 10% response speed across all three PVT durations. Slowest 10% reaction times, fastest 10% reaction times, false start and false start probability showed strong correlations between PVT-5 and PVT-10 but not between PVT-3 and PVT-10. Fastest 10% response speed did not share show strong correlations between the shorter PVTs and PVT-10. These findings suggest that some PVT-3 and PVT-5 metrics may be useful for tracking changes in vigilance in occupational settings where the PVT-10 may not be applicable.
