“…However, several of our field studies have demonstrated that the PDA-PVT is also suitable for use in the field, when conditions are often less than ideal. To date, we have successfully used this device in several work environments, including international flight operations, long-haul train travel, and mining operations (Baulk et al, 2007;Jay, Dawson, & Lamond, 200;Lamond et al, 2006;Petrilli et al, 2006). It is also imp^t to note that although the PDA-PYT may provide anlindication of the fatigue levels associated with a roster, it is simply a sustained attention task, not a test of higher cognitive functions.…”

“…Thus, whereas the standard length of the PVT in laboratory studies has often been 10 min, field studies involving the PDA-PVT have typically used a 5-min version of the task, since it is more practical for environments with time constraints (Baulk et al, 2007;Kamimori, Johnson, Thorne, & Belenky, 2005;Killgore, Killgore, Ganesan, Krugler, & Kamimori, 2006;McLellan, Kamimori, Bell, et al, 2005;McLellan, Kamimori, Voss, et al, 2005;Petrilli, Roach, Daw-N.

In this study, we evaluated the sensitivity of a 5-min personal digital assistant-psychomotor vigilance test (PDA-PVT) to severe sleep loss. Twenty-one participants completed a 10-min PVT-l92 and a 5-min PDA-PVT at two hourly intervals during 62 h of sustained wakefulness. For both tasks, response speed and number of lapses (RTs > 500) per minute significantly increased with increasing hours of wakefulness. Overall, standardized response speed scores on the 5-min PDA-PVT closely tracked those of the PVT-192; however, the PDA-PVT was generally apsociated with more lapses/minute. Closer inspection of the data indicated that when the level of sleep loss and fatigue became more severe (i.e., Day 3), the 5-min PDA-PVT was not quite as sensitive as the 10-min PVT-l92 when 2-to 10-sec foreperiods were used for both. It is likely, however, that the observed differences between the two devices was due to differences in task length. Thus, the findings provide further evidence of the validity of the 5-min PDA-PVT as a substitute for the 10-min PVT 192, particularly in circumstances in which a shorter test is required and/or the PVT-l92 is not as practical.

“…The focus of the current study was to evaluate sleep, fatigue and performance in smelter workers working a typical (DDNNOOOO), regular-rotating 12-h shift roster in order to determine the potential for disruption to the sleep-wake cycle, fatigue, reduced alertness and impaired performance as a result of extended work periods. This investigation formed part of a larger study to investigate several elements of 12-h shift schedules including the effects of workload and age on fatigue and performance (Baulk et al, 2007;Kandelaars et al, 2006).…”

Fatigue has been identified as a significant contributor to workplace accident rates. However, risk minimisation is a process largely based on selfreporting methodologies, which are not suitable for fatigue identification in high risk industries. Wearable technology which is capable of collecting physiological data such as step and heart rates as an individual performs workplace tasks has been proposed as a possible solution. Such devices are minimally intrusive to the individual and so can be used throughout the working day. Much is promised by the providers of such technology, but it is unclear how suitable it is for in-situ measurements in real-world work scenarios. To investigate this, we performed a series of studies designed to capture physiological and psychological data under differing (physical and mental) loading types with the intention of finding out how suitable such equipment is. Using reaction time (simple and choice) as a measure of performance we found similar correlations exist between loading duration and our measured indicators as those found in large-scale laboratory studies using state of the art equipment. Our results suggest that commercially available activity monitors are capable of collecting meaningful data in workplaces and are, therefore, worth investigating further for this purpose.
