Since seafarers are known to be exposed to numerous job-related stress factors that can cause fatigue, sleepiness, and disturbed sleep behaviour, the aim of this review was to provide an overview of the subjective and objective measurement methods of these strains. Using a systematic review, 166 studies were identified within the period of January 2010 to December 2020 using the PubMed database. Of the 21 studies selected, 13 used both subjective and objective measurement methods. Six studies used only subjective and two studies only objective methods. For subjective assessment, 12 different questionnaires could be identified as well as activity and sleeping logs. Actigraphy and reaction time tests (RTT) were the most common objective methods. In single cases, electrooculography (EOG), pupillometry and ambulatory polysomnography (PSG) were used. Measurement-related limitations due to vessel-related impacts were less often reported than expected. No restrictions of daily routines on board were described, and only single-measurement disturbances due to ship movements were mentioned. The present literature review reveals that there are various routines to measure fatigue, sleepiness, and sleep behaviour on board. A combination of subjective and objective methods often appears to be beneficial. The frequent use of actigraphy and RTT on board suggests good feasibility and reliable measurements with these methods. The use of ambulatory PSG in maritime-like contexts suggests that this method would also be feasible on board.

Background: Nurses are facing unprecedented amounts of pressure because of the ongoing global health challenges. Improving nurses' resilience to job-related stress and enhancing their strategies to cope effectively with stressors are key issues facing many health care institutions during the COVID-19 pandemic. This literature review aimed to: a) provide a thorough overview of individual-level interventions for stress management among nurses, b) identify measurement tools utilized to evaluate nurses' stress level, and c) provide the best evidence-based recommendations for future research and practice adapted to the current restrictions.Design: Systematic review.Data Sources: Studies published between January 2000 and October 2020 were retrieved from the following sources: EBSCOhost, Dortmund University Library, PubMed, Medline, Google Scholar, Applied Nursing Research, and reference lists from relevant articles.Review methods: Individual-level interventions with a control group or a placebo intervention were included in the final sample. Primary outcome was defined as a change in individual stress level or stress symptoms which were measured by objective or subjective instruments with evidence of validity. Articles published in English or German were included in the present review.Results: In total, 27 relevant studies were included into the current review. There are some indications that technology-delivered interventions with relaxation and stress management interventions comprising cognitive-behavioral components might be effective in decreasing stress among nurses and improving their well-being. Furthermore, although there were some attempts to collect objectively measured parameters for assessing the primary outcome of stress, the majority of the interventions utilized self-reported stress scales.Conclusion: A wide range of interventions are available for nurses. However, it is of utmost importance to develop and implement stress management programs that are conveniently accessible in the workplace and above all, meet the current restrictions for minimizing human contacts. To this end, innovative interventions delivered through digital technology, such as virtual reality, seem to be a promising solution for combating the detrimental impact of stress on nurses. Special attention should be also paid to applying standardized objective measurement tools to allow the assessment of sensitive physiological indices and the generalizability of scientific knowledge.

The present study was intended to explore the potential relationships between self-esteem and affective temperament (Akiskal et al., 2005) of nurses working for Psychiatric and Mental Health Departments. The ultimate goal is to establish which factor determines their professional stress and adaptation.Methods:Self-administered questionnaires were given to 152 nurses employed in three Portuguese public hospitals. The questionnaire items included socio demographic and job-related data and two scales: the Portuguese version of TEMPS-A Scale (Akiskal, 2005) and the Personal Self-esteem Scale (Ribeiro, J.L.P 2006). For statistical analysis besides descriptive statistics, a correlation model was used.Results:Hyperthimic Temperament was the more prevalent subtype. Women presented a higher Self-esteem positively correlated with Ciclothymic and Anxious temperaments. The results also show that there is a correlation between marital status and Irritable Temperament, and between the years of professional experience and the Cyclothymic and Hyperthymic Temperaments.Conclusion:An interaction between temperament subtypes, self-esteem and professional experience was observed. Gender differences are also significant. Further study is needed to investigate the potential relationship between temperament, self-esteem and professional satisfaction and resilience to job-related stress factors in Psychiatric Departments.


Background: A large proportion of women in the workforce including part-time workers and full-time workers are in the period of menopausal transition. The degree and kind of menopausal symptoms may be different in full-time workers and part-time workers since the contents of job-related stress in full-time workers and part-time workers are different. We compared menopausal symptoms and job-related stress factors in full-time workers and part-time workers and the associations of menopausal symptoms with job-related stress in both groups. Methods: Health questionnaires including Greene’s climacteric scales and job-related stress scores were given to 613 female general workers aged 45-60 years in Japan. Results: Total Greene’s climacteric scores were not significantly different in full-time workers and part-time workers. Symptoms with high frequencies in both full-time and part-time workers were feeling tired or lacking in energy, loss of interest in sex and irritability. Scores for quantitative overload, qualitative overload and interpersonal relationships in full-time workers were significantly lower than those in part-time workers, while scores for physical overload and workplace environment in part-time workers were significantly lower than those in full-time workers. Psychological symptoms showed significant associations with job control, interpersonal relationships, workplace environment, job fitness and job satisfaction in full-time workers. Conclusions: The degree of job-related stress and the association of job-related stress with menopausal symptoms were different in full-time workers and part-time workers, though menopausal symptoms were similar in full-time and part-time workers. Different strategies for management of menopausal symptoms may be needed in full-time workers and part-time workers.
