Cumulative psychological strain and future strain in Naval personnel: is executive function the elephant in the room?

The relationship between psychological distress and cognitive failure among breast cancer survivors: a network analysis

Background

Psychological distress is highly prevalent and has a severe impact on the quality of life among breast cancer survivors. This type of distress is associated with cognitive failure. However, previous studies have focused solely on the total scale scores of these two concepts while ignoring the unique relationship between specific components. In the present study, we utilized network analysis to explore the relationship between psychological distress and cognitive failure in breast cancer survivors.

Methods

The network analysis approach was adopted to estimate the regularized partial correlation network in a cross-sectional sample of 409 breast cancer survivors. All participants were assessed using the Depression Anxiety Stress Scale and the Cognitive Failure Questionnaire. The Gaussian Graphical Model was employed to estimate the network, centrality indices, and edge weights, providing a description of the characteristics of the network.

Results

The results indicated that anxiety-stress and depression-stress were the strongest edges in the community of psychological distress. Distractibility-memory was the strongest edge in the community of cognitive failure. Distractibility and memory were the most central nodes, with the highest expected influence in the network. Depression and motor coordination acted as important bridge nodes with the highest bridge expected influence.

Conclusion

Distractibility and memory in cognitive failure played important roles in activating and maintaining the relationship network. Motor coordination was identified as the crucial pathway for the impact of cognitive failure on psychological distress. Interventions targeting these specific issues might be more effective in improving cognitive failure and reducing psychological distress among breast cancer survivors.

The Effect of Surface Acting on Job Stress and Cognitive Weariness Among Healthcare Workers During the COVID-19 Pandemic: Exploring the Role of Sense of Community

Surface acting (SA) is a heavy emotional and cognitive task practiced by nurses, which has negative consequences on their wellbeing. The shortage of nurses along with the occurrence of the COVID-19 pandemic has worsened the situation. Based on job demands-resources (JD-R) and conservation of resources theories, this study aims to investigate the adverse impact of practicing SA and buffering effect of a sense of community (SOC) on job stress (JS) and cognitive weariness (CW) among Iranian nurses confronting COVID-19. As this study is written within the scope of Frontiers' call for research on "Spirituality in the workplace," the findings suggest that the aforementioned factors are in significant positive relationships. Furthermore, the empirical evidence indicates that there is a significant indirect effect of SA on CW through JS. In addition, results reveal that there is a buffering effect of SOC on the SA and JS relationship, while there is no significant moderation effect regarding the JS and cognitive weariness association. The findings of this study provide theoretical and practical implications within the scope of spirituality in the workplace.

Neuropsychological sequelae of work-stress-related exhaustion

The aim was to assess long-term cognitive performance after substantial recovery from work-stress-related exhaustion, in relation to subjective cognitive complaints and return to active work. In total, 54 patients previously diagnosed with work-stress-related exhaustion participated in a neuropsychological examination ∼2 years after initial sick leave. Most participants were substantially recovered at follow-up, with only 13% still meeting the criteria for exhaustion disorder suggested by the Swedish National Board of Health and Welfare. When participants' scores on 14 neuropsychological tests were compared to a matched group of 50 controls, the former patient group showed lower performance mainly on attention tests of the reaction time type, but also slightly lower scores on visuo-spatial constructional ability. However, the former patient group performed better than controls on two memory tests and, in part, on a test of simultaneous capacity. Self-ratings of everyday cognitive problems remained significantly higher in the former patient group than among controls, but the extent of self-rated cognitive problems was generally unrelated to performance on the neuropsychological tests. No relationship between performance on these tests and the extent of work resumption was observed. In summary, persons with previous work-stress-related exhaustion showed persistent signs of a minor attention deficit, despite considerable general recovery and return to work.

Occupational stress and employee turnover

Questionnaire data captured in January-March 2007 were examined in relation to turnover in males and females during the next five years. In general, most of the workplace stressors (such as role conflict or peer support) were not antecedents of turnover in any group. Junior personnel with psychological strain in 2007 had an increased risk of turnover in the next five years. Low commitment to the service in 2007 increased the odds of turnover in male and female juniors and in female officers. Female juniors with less effective skills for coping with stress and who exercised less frequently on a weekly basis were more likely to leave. An incidental finding was that the odds of turnover were three times greater in female officers with children than in female officers with no children. Stress management interventions focusing on effective coping and sports and exercise participation which are targeted appropriately may improve retention.

Psychometric properties of the Cognitive Failures Questionnaire

The Cognitive Failures Questionnaire (CFQ) is used in ergonomics research to measure behavioural problems associated with attentiveness and memory in everyday life. CFQ scores have been related to constructs such as accident proneness and outcomes such as human error and psychological strain. The two-year test-retest reliability of the CFQ is reported together with the findings of factor analyses of CFQ data from 535 respondents. Evidence for the predictive and criterion validity and internal reliability of the CFQ is provided. Psychological strain was measured concurrently with CFQ on both testing occasions, two years apart. The test-retest reliability of the summated CFQ score was found to be 0.71, while for the General Health Questionnaire (GHQ-12) strain measure it was 0.32.The relative variance stability was five times greater for the CFQ than the GHQ, indicating that scores on these questionnaires are not covariates. The use of the CFQ as a measure of cognitive control capacity is also discussed.

PRACTITIONER SUMMARY

Ergonomists have long been interested in human error and the role of high work demands due to poor equipment design and excessive workload. The CFQ measures attentiveness in daily life and is shown to have excellent psychometric properties that make it suitable for use in both laboratory and field studies as a trait measure of attentiveness in daily life.

Railway-controller-perceived mental work load, cognitive failure and risky commuting

This questionnaire study tests cognitive failures as a mediator of the potential influence of mental work demands and conscientiousness on risky commuting. Participants were 104 railway-controllers (19% female). Failure of memory, attention regulation and action execution were assessed with the Workplace Cognitive Failure (WCF) scale. Mental work demands were measured by the Instrument for Stress-Oriented Task Analysis (ISTA). A structural equation model testing WCF as the mediator of (1) the relationship between mental work demands and risky commuting (p < 0.05) and (2) the link between conscientiousness and risky commuting (p < 0.05) fitted well with empirical data. In railway-controllers frequent interruptions, time pressure, and high concentration demands are likely to increase cognitive load and thereby boost WCF during work and also during commuting, thereby reducing commuting safety. The results underline the need for work redesign to improve commuting safety.

PRACTITIONER SUMMARY

Commuting accidents occur frequently and at high cost. This study shows that mental work demands of railway staff are related to cognitive failure and risky commuting behaviour such as failing to give way and overlooking stop signs. Primary prevention of commuting accidents should include reduction of mental workload.

Sustaining person-environment fit with a changing workforce

Data on health and lifestyle from the Naval service cohort study of occupational stress form the background to a discussion of employee health and the sustainability of a healthy workforce in relation to secular changes - in particular, the increasing prevalence of obesity. One thousand two hundred and forty-one Naval personnel returned questionnaires in 2007 and 2011 and reported their body mass index (BMI), alcohol consumption and smoking, general health and health conditions such as back pain and high blood pressure on both occasions. Health risk due to high BMI and waist circumference in 2011 was predicted by low participation in exercise in 2007. Those performing physically demanding work in 2007 were more likely to be in the 'no risk' category in 2011. High BMI in 2007 was associated with the development of back pain, musculoskeletal conditions and high blood pressure in 2011. The findings are discussed in relation to two aspects of sustainability: the sustainability of current ergonomics practice in relation to health and safety; and the role of ergonomics in sustaining a healthy and productive workforce.

PRACTITIONER SUMMARY

Evidence is presented for the benefits of exercise in sustaining employee health and for an association between a high BMI and a number of common health complaints that have traditionally been tackled through workplace ergonomics. This evidence can be used to support the development of workplace design concepts that promote physical activity.
