Abstract

The purpose of this study was to evaluate the reliability of many variables in the 5-minute Psychomotor Vigilance Test (PVT). Many studies have looked at the validity of a 5-minute PVT, but few so far have looked at reliability. For this study, 13 adult females who worked 12-hr shifts were recruited to complete a two trial day study. The first trial day, the subjects submitted health questionnaire followed by a self-reported sleepiness scale and then a 5-minute PVT. The second trial session the subjects only competed the sleepiness scale followed by the 5-minute PVT. After analyzing the data, it was found that the fastest 10% of reaction time (F10RT%) and the mean reaction time (MRT) were the 2 most reliable variables based upon their ICC scores. The self-reported sleepiness scale showed moderate reliability and a mirroring effect in the subjects' PVT outcomes. Overall, the 5-minute PVT is a reliable tool to use to measure fatigue levels in female adult shift workers.
