摘要

Submarine duty is one of the most stressful jobs in the military. Approximately 50 percent of attrition in the submarine force stems from psychological and stress-related disorders. The purpose of this study was: (1) determine the relationship between parameters of the diurnal rhythm of salivary cortisol (SC) and psychological markers of stress, sleep, and the Navys submarine duty screening tool, SUBSCREEN; and (2) determine the relationship between SUBSCREEN and both physiological stress biomarkers (SC and salivary alpha amylase (SAA)) and psychological stress responses during a stressful training event. Sixty-eight subjects collected diurnal SC saliva samples over 2 days at Basic Enlisted Submarine School, and 56 subjects collected 5 saliva samples for SC and SAA during the Wet Damage Control Trainer. A 3-level model was used to predict diurnal SC parameters. Stress reactivity data were analyzed using Pearsons r and RMANOVA, and qualitative data analyzed for themes and subjects responses coded into stress group (Yes or No Stress groups), with subsequent exploratory analysis conducted. The self-criticism scale is the only SUBSCREEN scale associated with diurnal SC rhythm. Furthermore, SC parameters are modified by state- and trait-positive affect, sleep duration and wake-up time, chronotype status, and compliance.
