Stress dynamics in long-term isolation at sea. A demographic variables model

Area of Science:

• Occupational Health
• Marine Biology
• Psychology

Background:

• Long-term work-related isolation, such as that experienced by fishermen, can significantly impact mental well-being.
• Understanding the dynamics of stress in such environments is crucial for improving crew welfare.
• Previous research has not fully explored the interplay of social-demographic factors with stress in this specific occupational group.

Purpose of the Study:

• To investigate stress levels among fishermen during a prolonged sea expedition.
• To identify social-demographic variables that correlate with stress dynamics in this population.
• To provide insights for managing occupational stress in isolated work settings.

Main Methods:

• A naturalistic research program was conducted during a 6-month expedition in the southern Atlantic Ocean.
• Stress levels of 81 fishermen were measured four times throughout the expedition.
• Social-demographic data, including age, experience, job satisfaction, education, and residence history, were collected and analyzed.

Main Results:

• Stress levels varied among participants over the expedition period.
• Several social-demographic variables were found to be associated with stress dynamics.
• Factors such as age, years at sea, and job satisfaction emerged as important considerations.

Conclusions:

• Social-demographic variables are critical factors in understanding stress patterns among fishermen.
• The findings underscore the need to consider individual differences when addressing occupational stress in isolated work environments.
• This research contributes to the development of targeted interventions for improving the psychological well-being of seafarers.
