Effects and mediators of psychosocial work characteristics on somatic symptoms six years later: Prospective findings from the Mannheim Industrial Cohort Studies (MICS)

Psychological Flexibility Is Associated with Parental Stress in Relatives of People with Intellectual Disabilities

The objective of the study was to examine the relationship between psychological flexibility, perceived stress, and psychological heath in relatives of people with a disability diagnosis. 151 relatives completed an online questionnaire that included 6-PAQ (parental psychological flexibility), PSS (perceived stress), GHQ-12 (psychological health) and WBSI (suppression of unwanted thoughts). The results showed significant relationships between the four measured variables. A bimodal distribution was observed in the variables related to psychological flexibility. The multiple regression showed that difficulties in self as context, committed actions and defusion explain a high percentage of the variance of parental stress and general psychological health. The study provides new evidence to consider psychological flexibility as a mediating variable in psychological well-being. The presented data served as the basis for the development of an ACT-based intervention protocol and the implementation of a clinical trial for relatives of children with disabilities.

Associations between chronic work stress and plasma chromogranin A/catestatin among healthy workers

OBJECTIVES

Plasma chromogranin A (CgA) may play a critical role on linking work stress to health outcomes. The aim of our study was to investigate the associations between work stress and plasma CgA levels in healthy workers without chronic diseases.

METHODS

The study included 260 healthy workers from EHOP study. Work stressors were assessed by the Chinese version of the 23-item ERI-Q questionnaire. Plasma CgA and catestatin levels were measured by ELISA kits. The demographic characteristics were collected from medical records.

RESULTS

Among the final 260 subjects including 173 males (66.5%) and 87 females (33.5%), the average age was 37.6 ± 10.6 years old. Effort, overcommitment, and ERI were positively associated with plasma CgA level, respectively (r = 0.267, 0.319, and 0.304, all p < .001), while reward was negatively associated with CgA level (r = -0.237, p < .001). The workers with high effort, overcommitment, or ERI had significantly higher plasma CgA levels, while the workers with high rewards had significantly lower plasma CgA levels. The workers with both high overcommitment and high ERI had highest plasma CgA levels. In the linear regression analysis, after adjustment for confounders, effort, overcommitment, and ERI were respectively positively related to plasma CgA, while reward negatively related to plasma CgA. The associations between work stress and plasma catestatin was not significant. The ratio of CgA and catestatin was associated with work stress.

CONCLUSIONS

Work stress is associated with plasma CgA which may be play a crucial role on the pathway from chronic work stress to cardiovascular diseases.

Understanding the nature and impact of occupational stress on Australian rural aged care workers

This study explored the nature and impact of occupational stress on direct-care workers employed by aged care providers in rural Australia. The Job demands-Resources (JD-R) model of occupational stress provided the theoretical framework to guide this qualitative investigation. A series of four FGs were conducted with direct-care workers (n = 23), who reported their job demands, job resources and personal resources. Direct-care workers identified six themes related to job demands: time pressure, physical demands, hindrance demands, an inadequate mix of staff, insufficient training to deal with complex conditions and work schedule demands. Four themes related to job resources were identified: collaboration with colleagues, equipment, opportunities for development and work schedule control. Disposition and self-care were identified as necessary personal resources for aged care workers. While the generic JD-R questionnaire captures many relevant workplace characteristics, further investigations with this work group should also consider the inclusion of items related to shift work, disposition and self-care.

The Interactive Effects of Cognition on Coping Styles among Chinese during the COVID-19 Pandemic

BACKGROUND

The outbreak of Coronavirus Disease 2019 (COVID-19) has seriously affected people's life. The main aim of our investigation was to determine the interactive effects of disease awareness on coping style among Chinese residents during the COVID-19 pandemic.

METHODS

A total of 616 Chinese residents from 28 provinces were recruited to participate in this investigation. A questionnaire was used to collect demographic characteristics, cognition of COVID-19, and disease-related stress sources. Coping styles were assessed via the Simplified Coping Style Questionnaire (SCSQ).

RESULTS

The survey showed that the main source of information on COVID-19 was different in relation to gender, age, educational level, and occupation (p < 0.001). People's knowledge of the disease, preventive measures, and stress factors were different in relation to demographic characteristics (p < 0.001). Compared with the baseline values, the scores of positive coping and negative coping based on SCSQ in relation to gender, age, educational level, and occupation were statistically significant (p < 0.001, except for participants older than 60 years). Different educational levels corresponded to statistical significant differences in positive coping (p = 0.004) but not in negative coping.

CONCLUSIONS

During the pandemic, people with different characteristics had different levels of preventive measures' awareness, which influenced their coping styles. Therefore, during public health emergencies, knowledge of prevention and control measures should be efficiently provided to allow more effective coping styles.

Triggers and Clinical Presentations of Functional Neurological Disorders: Lessons from World War 1

INTRODUCTION

The psychological contribution to functional neurological and somatic symptom disorders is a major topic in current medical debate.

OBJECTIVE

For an understanding of the processes leading to functional somatic symptoms, it is paramount to explore their relationship with stress and life events and to elucidate the contribution of cultural factors.

METHODS

A total of 937 case records of civilian and military patients with functional somatic disorders treated in London during World War 1 were analysed. Group differences in symptom profiles and contemporaneous diagnoses were tested with χ2 tests.

RESULTS

Paralyses and speech disturbances were significantly more common in soldiers (43.3 and 17.2% of cases) than in civilian male (28.1 and 6.5%) and female patients (32.4 and 7.5%), whereas female patients had the highest rates of pain (48.6%) and somatic symptoms (67%). Triggers were identified in around two-thirds of cases and included accidents, physical illness, and work stress, in addition to the combat experience of the soldier patients. The nature of the trigger influenced symptom expression, with acute (combat and noncombat) events being particularly prone to trigger loss of motor function. Symptom profiles showed a great deal of multi-morbidity and overlap, although some symptom clusters were more (motor and speech disturbance) or less common (pain and loss of energy) in soldiers than civilians. Triggering life events in civilians were similar to those reported by patients with somatic symptom disorders today, with an important role of physical factors. Patterns of multi-morbidity and symptom clusters also resembled those of modern cohorts.

CONCLUSIONS

Analysis of historical records, illness trajectories, and treatments can enhance the understanding of the presentation, mechanisms, and course of functional neurological and related disorders and their consistency over time.

Health-related quality among life of employees with persistent nonspecific indoor-air-associated health complaints

OBJECTIVE

Nonspecific health complaints associated with indoor air are common in work environments. In some individuals, symptoms become persistent without an adequate explanation. The aim was to study factors that associate with the health-related quality of life (HRQoL) of employees with persistent, nonspecific indoor-air-related symptomatology.

METHODS

We present baseline results of a randomized controlled trial of interventions targeted on the HRQoL of the employees with indoor-air-associated nonspecific symptoms. The main participant-inclusion criterion was the presence of persistent indoor-air-related multiorgan symptoms with no known pathophysiological or environment-related explanation. As a comparison for participants´ HRQoL (n = 52) we used data from the general-population Health 2011 study (BRIF8901) including information on subjects matched to the participants´ working status and age and subjects with asthma, anxiety or depressive disorder, or other chronic conditions with work disability.

RESULTS

The participants showed greater and a clinically significant impairment of HRQoL [M = 0.83, SE = 0.013] than individuals from the general population [M = 0.95, SE = 0.001, p < .001, Hedges´ g = 2.33] and those with asthma [M = 0.93, SE = 0.005, p < .001, Hedges´ g = 1.46], anxiety and depressive disorder [M = 0.89, SE = 0.006, p < .001, Hedges´ g = 0.73], or a chronic condition with work disability [M = 0.91, SE = 0.003, p < .001, Hedges´ g = 1.11]. Prevalent symptoms of depression, anxiety, and insomnia and poor recovery from work were associated with a poor HRQoL.

CONCLUSIONS

Individuals with nonspecific indoor-air-associated symptoms have a poorer HRQoL than individuals in the general population with a globally burdensome disease. Psychological distress associated with a poor HRQoL should be considered in the making of decisions about the treatment of these patients.

Organizational justice, justice climate, and somatic complaints: A multilevel investigation

OBJECTIVE

Organizational justice refers to perceived fairness at the workplace. Individual perceptions of injustice have been linked to reduced mental and physical health. However, perceptions of injustice also exist at the aggregate level of departments, reflecting a shared perception, denoted as justice climate. There is evidence that this shared perception independently predicts individual distress levels (e.g., anxiety, depression), which might negatively affect somatic symptom perception and reporting. Hence, the objective of this study was to examine whether individual perceptions of poor justice as well as a poor justice climate are related to elevated somatic complaints. In addition, this study examined if justice climate moderates the relationship between individual-level justice perceptions and somatic symptom reporting.

METHODS

Cross-sectional data from a large industrial manufacturing company was used, involving 1,102 employees in 31 departments. A validated scale covering interactional and procedural justice assessed individual-level organizational justice. A 19-item symptom checklist measured somatic complaints. Multilevel analyses estimated individual-level associations (within-department effects) with somatic complaints, department-level associations (between-department effects), and the cross-level interaction of both.

RESULTS

Individual-level justice perceptions were negatively associated with somatic complaints. Collective justice climate was likewise significantly associated with somatic complaints. There was no indication for a moderation effect of justice climate.

CONCLUSION

A poor justice climate correlated positively with individual somatic complaints while controlling for individual perceptions, i.e., above and beyond individual justice perceptions. These findings may imply that interventions targeting department-level perceptions of justice may have the potential to reduce individual somatic complaints beyond the effects of individual-level interventions.

The link between stress, well-being, and psychological flexibility during an Acceptance and Commitment Therapy self-help intervention

Background/Objective: Prolonged stress can overwhelm coping resources, leading people to seek mental health care. Acceptance and commitment therapy (ACT) is an intervention that enhances well-being and reduces distress, assumedly by means of increasing psychological flexibility (PF). We examined the association between a total increase in PF during an intervention and decreases in stress and increases in well-being during and after the intervention. Method: The intervention was a randomized controlled trial of an ACT-based self-help intervention. Participants were 91 individuals reporting elevated levels of work-related stress. Measurements were completed at preintervention, postintervention, and 3-month follow-up. Results: Structural equation models revealed that the total increase in PF during the intervention was negatively associated with a decrease in stress (b = -0.63, SE = 0.14, p < .001) and positively associated with an increase in well-being during the intervention (b = 0.48, SE = 0.11, p < .001), but not with a decrease in stress (b = 0.03, SE = 0.27, p > .05) and well-being (b = -0.04, SE = 0.39, p > .05) following the intervention. Conclusions: Our study provides empirical support for decreasing stress and promoting well-being through ACT and emphasizes the potential of PF in promoting well-being.
