Effects of an on-board psychosocial programme on stress, resilience, and job satisfaction amongst a sample of merchant seafarers.

BACKGROUND: Seafarers are an occupational group amongst those at highest risk for stress, which may adversely affect their mental health. The primary aim of this study was to assess the effects of a psychosocial programme on perceived stress, resilience, and job satisfaction among a sample of merchant seafarers. MATERIALS AND METHODS: Secondary data analysis was conducted using a work questionnaire administered by a large shipping company. The matched subjects technique and multivariate analysis of covariance were conducted using a theoretical model of the programme's effects on job satisfaction, resilience, and perceived stress. RESULTS: A significant interaction between programme participation and weeks on board indicated that the effects of weeks on board on perceived stress differed significantly for the intervention group and matched control group. Weeks on board had a significant effect for perceived stress for the control group (p = 0.02), but not for the intervention group (p = 0.857). CONCLUSIONS: These findings indicate that participation in the programme moderated the effects of weeks on board on perceived stress, suggesting that the programme may have safeguarded participants against the effects of weeks on board on perceived stress. Importantly, however, a work environment that is experienced as supportive, inclusive and just is necessary as a cornerstone for individually-focused psychosocial interventions to be optimally applied.

Identifying Predictors of Stress and Job Satisfaction in a Sample of Merchant Seafarers Using Structural Equation Modeling.

Background: Seafarers are amongst occupational groups with the highest risk for stress, a factor known to impact on mental health. Psychological issues such as depression, anxiety, suicide, and alcohol or drug dependence are recognized health problems within the maritime sector. The primary aim of this study was to identify which individual and occupational factors, known to impact on psychological functioning across the maritime industry and other sectors, best predict perceived stress and job satisfaction among a sample of merchant seafarers. Methods: Secondary data analysis was conducted using a work experiences and attitudes questionnaire administered by a large shipping company to seafarers within their organization. Structural equation modeling was conducted using a proposed theoretical model of perceived stress and job satisfaction in a sample of merchant seafarers. Results: While the structural equation model produced acceptable fit to the sample data according to numerous goodness-of-fit statistics, the comparative fit index and Tucker-Lewis index results indicated less than satisfactory model fit. The model explained 23.8% of variance in the criterion variable of perceived stress, and the strongest predictive effect was for dispositional resilience. The model explained 70.6% of variance in the criterion variable of job satisfaction, and the strongest predictive effect was for instrumental work support. Conclusion: When addressing the psychosocial well-being of merchant seafarers, findings of this study suggest that dispositional resilience may be a particularly important factor with regards to perceived stress, while instrumental work support appears to be a critical factor in relation to job satisfaction. Importantly, however, an overall work environment that is perceived by employees as supportive, equal and just is a cornerstone for the psychosocial well-being of seafarers.

Resilience and well-being amongst seafarers: cross-sectional study of crew across 51 ships.

OBJECTIVES: Duration at sea was investigated as a potential chronic stressor amongst seafarers in addition to the mediating roles of previous seafaring experience and hardiness between duration and stress. METHODS: In a cross-sectional design, questionnaires were emailed to 53 tanker vessels in an international shipping company with questions relating to duration at sea, perceived stress, personality hardiness and work characteristics. The sample comprised 387 seafarers (98% male) including ratings, crew, officers, engineers, and catering staff that had been on board their ship between 0 and 24 weeks. RESULTS: Duration at sea was unrelated to self-reported perceived stress, even after controlling for previous seafaring experience and hardiness. Additional regression analyses demonstrated that self-reported higher levels of resilience, longer seafaring experience and greater instrumental work support were significantly associated with lower levels of self-reported stress at sea. CONCLUSIONS: These results imply that at least for the first 24 weeks at sea, exposure to the seafaring environment did not act as a chronic stressor. The confined environment of a ship presents particular opportunities to introduce resilience and work support programmes to help seafarers manage and reduce stress, and to enhance their well-being at sea.
