The short form effort-reward imbalance: Measure of occupational stress for firefighters

Job Stress and Sleep Disturbances Among Career Firefighters in Northern California

OBJECT

This study examined the association between job stress and sleep disturbance among career firefighters.

METHODS

A cross-sectional survey study was conducted with 154 career firefighters working in Northern California, US job stress was measured using the short form of the Effort-Reward Imbalance questionnaire and sleep was measured with the Patient-Reported Outcomes Measurement Information System Sleep Disturbance.

RESULTS

Approximately 75% experienced sleep disturbance. For firefighters' job stress, high effort (odds ratio [OR] = 3.68; 95% confidence interval [CI]: 1.25-10.80), high effort-reward ratio (OR = 3.55; 95% CI: 1.23-10.23), and high overcommitment (OR = 9.09; 95% CI: 2.30-35.85) were significantly associated with increased likelihood of sleep disturbance, after adjustment for other factors.

CONCLUSIONS

Job stress significantly affected firefighters' sleep health, suggesting the need to design effective health promotion interventions to reduce job stress and improve sleep quality for these public service workers.

Factors Influencing Infection Anxiety in Korean Male Firefighters Due to COVID-19 Infection Status

This paper describes descriptive research to identify the effects of job stress, COVID-19 self-care behavior, and COVID-19 vaccination status according to the infection and non-infection of COVID-19 on anxiety about the COVID-19 infection among firefighters in South Korea. Data from 205 firefighters working at 10 fire stations were collected from 26 January to 16 February 2023. The variables used were job stress, COVID-19 self-care behavior, COVID-19 vaccination status, and COVID-19 infection anxiety. The collected data were analyzed using descriptive statistics, t-test, one-way ANOVA, Pearson's correlation coefficient, and multiple linear regression. In subjects who were infected with COVID-19, the factors that significantly affected infection anxiety were job stress (β = 0.247, p = 0.011) and self-care behavior (β = 0.343, p = 0.011). In subjects who were not infected with COVID-19, the factors that significantly affected infection anxiety were marriage status (unmarried) (β = -0.260, p = 0.005) and self-care behavior (β = 0.374, p = 0.001). These results demonstrate that the infection anxiety of firefighters should be prevented, and their physical and mental health should be promoted by considering job stress, self-care behavior, and personal environment.

Association of Occupational Stress With Tinnitus Among Career Firefighters in the United States

OBJECTIVE

This study explores the relationship between occupational stress and tinnitus among firefighters, a group often exposed to two tinnitus risk factors: high stress and noise.

METHODS

This cross-sectional study includes 240 firefighters in the United States. Data describing demographic characteristics, occupational stress, noise exposure, and tinnitus were collected by survey. Occupational stress was measured using the short version of the Effort-Reward Imbalance Questionnaire.

RESULTS

Forty-three percent of participants reported experiencing tinnitus within the past month. For occupational stress, higher effort (odds ratio, 1.25; 95% confidence interval, 1.05 to 1.49) and higher effort-reward ratio (odds ratio, 12.28; 95% confidence interval, 3.08 to 48.86) were associated with increased odds of tinnitus, after adjustment for demographic characteristics and noise exposure.

CONCLUSIONS

Occupational stress may increase the likelihood of tinnitus for firefighters, an already at-risk group of workers. Health providers should incorporate stress assessment into tinnitus management programs.

Where is the limit for overtime? Impacts of overtime on employees' mental health and potential solutions: A qualitative study in China

Although Labor Law of the People's Republic of China stipulates the overtime system, overtime is still widespread in the IT industry. Through qualitative interviews, we explored the impact of overtime on employees' mental health and life. The current study identified four main themes, namely overtime reasons, outcomes of overtime, influential factors and solutions to overtime challenges. Besides work-related reasons and cultural influence, it was found that employees may work overtime due to personal reasons, such as capability and personal qualities; the most frequent impacts reported were fatigue, depression, stress and interference with life; three predominant influential factors were timing of overtime, control and rewards; and overtime conditions could be improved in practical and emotional ways. The study's findings highlight the importance of the design of flexible working time arrangements for avoiding fatigue and improving employees' work-life balance, enhancement of schedule arrangement for avoiding daily work interruption and last-minute tasks, and optimization of rewarding systems for avoiding complaints and facilitating voluntary overtime. Results suggest that mental health and work-life balance can be promoted by organizational initiatives focusing on minimizing excessive job demands, increasing psychosocial resources, supporting boundary management, and enhancing perceived flexibility.

Working Conditions and Wellbeing among Prison Nurses during the COVID-19 Pandemic in Comparison to Community Nurses

The psychological health and work challenges of nurses working in prisons during the COVID-19 pandemic are understudied. We evaluated the work and wellbeing characteristics of a California prison nurse group, with a comparison to those of a community nurse group. From May to November 2020, an online survey measured psychosocial and organizational work factors, sleep habits, psychological characteristics, COVID-19 impacts, and pre-pandemic recall among 62 prison nurses and 47 community nurses. Prison nurses had significantly longer work hours (54.73 ± 14.52, p < 0.0001), higher pandemic-related work demands, and less sleep hours (5.36 ± 1.30, p < 0.0001) than community nurses. Community nurses had significantly higher pandemic-related fear levels (work infection: p = 0.0115, general: p = 0.0025) and lower perceived personal protective equipment (PPE) supply (p = 0.0103). Between pre-pandemic and pandemic periods, both groups had significantly increased night shift assignments and decreased sleep hours, but the prison group had increased work hours. Although not statistically significant, both groups had high occupational stress and prevalence of post-traumatic stress symptoms. Our results indicate that prison nurses experienced work and wellbeing challenges during the pandemic. Future research and practice ought to address nurses' workload, PPE, and psychological resources in correctional facilities and healthcare organizations.
