    Young Navy recruits facing acute stress showed significant links between cortisol levels, defense mechanisms, and anxiety. This research explores psychological responses to military training stressors.

    Area of Science:

    • Psychology
    • Endocrinology
    • Military Medicine

    Background:

    • Acute stress situations can elicit significant physiological and psychological responses.
    • Understanding defense mechanisms is crucial for managing stress in high-pressure environments like military service.

    Purpose of the Study:

    • To investigate the relationship between endocrine responses, defense mechanisms, and anxiety in young men undergoing an acute stress test.
    • To identify specific endocrine factors correlating with psychological defense strategies during stress.

    Main Methods:

    • Sixty-two non-swimming male Navy volunteers were subjected to a stressful jump into a pool.
    • Blood and urine samples were collected for endocrine analysis (Cortisol, Testosterone, Catecholamines).
    • Psychological assessments included the Defense Mechanism Test (DMT), COPE, J&N Scales, and a Mood Questionnaire (MQ).

    Main Results:

    • Three primary endocrine factors were identified post-stress: Cortisol, Testosterone, and Catecholamine.
    • A significant correlation was found between the Cortisol factor and defense mechanisms assessed by DMT and paper-and-pencil tests.
    • High anxiety levels were significantly related to specific defense mechanisms and physiological responses.

    Conclusions:

    • Cortisol levels are significantly associated with an individual's defense mechanisms during acute stress.
    • Anxiety and defense strategies play a key role in modulating physiological stress responses in military recruits.
    • Findings highlight the interplay between psychological coping and endocrine function under duress.
