Background and Aim: People working in sensitive positions in the Navy are highly exposed to stressful and critical conditions compared to other military forces. In this study, to evaluate the perceptual-cognitive functions of individuals, an efficient, non-invasive and relatively simple test called the PASAT test has been introduced.
Methods: In this case-control study, saliva samples were taken from the navy to determine salivary cortisol levels. Then, the DASS21 test was used to determine the level of stress in individuals and the results were compared with cortisol results. Individuals who had similar results in both tests were considered as stressed individuals and others were considered as controls. In a 10-minute training-test period, individuals were trained to perform the PASAT test. The outcomes of general cognitive health, reaction time, continuous attention and mental fatigue were evaluated.
Results: There was 10 naval personnel in each group. Salivary cortisol levels and reaction time were higher in the stress group than in the control group. General health and continuous attention in the control group were higher than the stress group, while mental fatigue in the control group was lower than the stress group.
Conclusion: Stress was able to affect all factors measured by the PASAT test. For this reason, the PASAT system seems to be suitable for evaluating the efficiency of individuals in various specialized and general occupations of the military forces that are exposed to chronic stress. |
