Risk factors for positive depression screening across a shipboard deployment cycle

Stressors and Support Experienced by Active Duty U.S. Navy Sailors at Sea

INTRODUCTION

High occupational stress is generally associated with poorer mental health and reduced performance in military personnel, whereas access to support resources is associated with positive outcomes. However, little research has examined the unique stressors and supports experienced by sailors on ships while underway at sea. The objectives of this study were to (1) identify sailors' underway stressors and supports and (2) examine how these differ as a function of demographic and operational factors.

MATERIALS AND METHODS

Active duty U.S. Navy sailors reporting an underway period lasting at least 30 days within the last 5 years (n = 441; 74.7% male, 90% enlisted) completed an anonymous retrospective survey. Sailors completed measures assessing underway stressors (25 items) and supports (9 items), as well as demographic, military, and operational characteristics (sex, rank, ship type, and underway duration). The study protocol was approved by the Naval Health Research Center Institutional Review Board in compliance with all applicable federal regulations governing the protection of human subjects.

RESULTS

Overall, the stressors rated as most problematic were exposure to loud noises, inability to rest when needed, unavailability of quality mental and physical health care, and not having enough people to complete the mission. Sailors perceived the most available supports to be opportunities to socialize, safety while performing duties, and finding ways to relieve stress. Female and enlisted personnel, relative to male and officer personnel, respectively, generally perceived stressors as more problematic and support resources as less available. Nearly half of the sample (48.3%) reported that services and programs to help them deal with stress while at sea were inadequate.

CONCLUSION

Sailors experience many stressors while underway. Increasing the resources available to underway sailors may be warranted, especially for female and enlisted personnel. Additional research is necessary to develop targeted interventions and resources. Possible recommendations include noise mitigation, berthing area improvements, sleep and/or scheduling interventions, improved access to mental and physical health care, and interventions to reduce the stigma associated with seeking mental health care.

Mental health and psychological wellbeing of maritime personnel: a systematic review

Background

Seafaring has frequently been reported to be a ‘risky occupation’ in terms of both physical and mental health. Individuals working in seafaring professions are exposed to various stressors in the workplace, including social isolation, exposure to poor physical conditions and long work hours. This systematic review aimed to update previous reviews by collating recent literature (published between 2012 and 2021) on the factors associated with mental health and wellbeing in seafaring personnel.

Methods

Four electronic databases were searched in April 2021 for primary peer-reviewed studies on factors associated with the mental health and psychological wellbeing of seafarers or interventions to improve the wellbeing of seafarers, published in English in or after the year 2012. Thematic analysis was used to synthesise the data and standardised measures of quality appraisal were used to assess risk of bias.

Results

Sixty-three studies were reviewed. Risk factors for poor mental health among seafarers appear to be younger age; being single; poor physical health; exposure to noise/vibration; feeling unsafe; high job demands; long working hours; night/irregular shifts; poor sleep; poor team cohesion; poor perception of management; poor social support; lack of autonomy; scheduling uncertainties; long duration at sea; and over-commitment.

Conclusions

There are numerous steps that maritime managers could take to improve the wellbeing of their personnel, including increased monitoring of the potential for poor mental health in their staff, increasing crew numbers and provision of education and support.

Mental health problems and their related factors among seafarers: a scoping review

BACKGROUND

Seafarers are often reported to be engaged in a dangerous physical and psychosocial work environment. However, mental health status among seafarers has not been focused on compared with physical health issues. Systematic, comprehensive reviews of mental health problems and their relevant factors are lacking. This review aimed to clarify beneficial approaches to the mental health problems faced among seafarers using a scoping review to systematically map the evidence regarding mental health issues and their related factors.

METHODS

Studies were searched on MEDLINE/PubMed, Science Direct, Academic search complete using EBSCOhost databases, SCOPUS, EMBASE, and Web of science on 20, August 2020. This scoping review was conducted based on the framework of Arksey and O'Malley and Preferred Reporting items for Scoping Reviews flow diagram. The inclusion criteria were studies which determined the relationship between factors relevant to working conditions or working environment, and mental health in seafarers, and etc. Data were narratively summarized and reported.

RESULTS

Twenty-four were included in this review while two major findings were clarified. Firstly, the prevalence of stress, depressive symptoms, and burnout have been mentioned for decades. Secondly, factors related to mental health and psychological issues can be categorized as individual and work environmental factors. The individual factors include experience, age, health status (high BMI, poor sleep, and diabetics), and resilience. The work environmental factors consist of two parts. Job demands comprise pressure from contractors/customers/time, working hours, ship department, job title, voyage episodes, period of seafaring, noise, and vibration. The job resources included instrumental support, team cohesion, shipboard caring and effort-reward imbalance.

CONCLUSIONS

A beneficial approach to mental health problems faced among seafarers is necessary to understand comprehensively at individual and organization levels. Promoting health behaviors, training resilience, and managing obesity and chronic diseases comprise individual level strategies. Providing seafarers with adequate instrumental support, and practical support to communicate with customers, managing their distinct work-rest hours and adequate effort-reward balance comprise organization level methods.
