Gender Differences With Regard to Perceived Job Insecurity and Insomnia in a Working Population

Taking stock and moving forward: A textual statistics approach to synthesizing four decades of job insecurity research

We collected the abstracts of manuscripts examining job insecurity published between 1984 and 2019 and carried out a textual analysis to investigate the defining clusters, their development over time, and whether there was evidence of siloed knowledge. Results suggested that job insecurity research seems to be fragmented into disciplinary foci (organizational psychology, public health, economics, and sociology). Further analyses on the organizational psychology corpus, revealed 25 topics with distinct temporal trajectories: some were increasing (analytical advances and differentiation between cognitive and affective job insecurity) while other were decreasing (scale development). The remaining abstracts revealed 15 topics with more stable trajectories. Based on these results, we identified five areas for future organizational research on job insecurity: the changing labor market, the need to better understand the experiences of marginalized workers and non-work outcomes of job insecurity, the added-value of qualitative research, and the need to critically evaluate our assumptions as researchers. Plain Language Summary Since the paper by Greenhalgh and Rosenblatt, research on job insecurity has burgeoned. Taking an interdisciplinary perspective, we collected the abstracts of all peer-reviewed manuscripts examining job insecurity published between 1984 and 2019 and carried out a textual analysis using the Latent Dirichlet Allocation and the Reinert method to investigate (a) the defining clusters of job insecurity research, (b) the development of such clusters over time, and (c) whether there was any evidence of siloed knowledge. Results suggested that indeed job insecurity research seems to be fragmented into four main disciplinary foci (organizational psychology, public health, economics, and sociology) with relatively little cross-fertilization. We conducted further analyses of the abstracts stemming from organizational research on job insecurity, revealing 25 topics with distinct temporal trajectories (e.g., “hot” topics including the increasing use of advanced analytic techniques and differentiation between cognitive and affective job insecurity) and “cold” topics including the development of job insecurity measures). The remaining abstracts revealed 15 topics with more stable research interests over time (e.g., a continued reliance on appraisal theories). Based on these results, we identified five areas for future organizational research on job insecurity based on: the changing labor market, the need to better understand the experiences of marginalized workers and non-work outcomes of job insecurity, the added-value of qualitative research, and finally the need to critically evaluate our assumptions as researchers.

The effect of exercise and affect regulation skills on mental health during the COVID-19 pandemic: A cross-sectional survey

BACKGROUND

COVID-19-related confinements pose a threat to mental health. We investigated prevalence rates of symptoms of depression, generalized anxiety and insomnia in German adults. Furthermore, we explored associations of exercise behavior with disorder-specific symptoms and assessed whether specific affect regulation skills enhance the effect of exercise on symptom alleviation.

METHODS

Cross-sectional survey-based data collected during the first lockdown is presented: 4268 adults completed questionnaires on mental health, exercise behavior and Covid-related lifestyle factors. Primary outcome was depression (PHQ-9), secondary outcomes generalized anxiety (PHQ-D) and sleep quality (PSQI). Multiple linear regression analyses were performed to examine the association of exercise behavior with the outcomes.

RESULTS

Analyses resulted in elevated symptoms of psychological distress (probable cases of depressive disorder: 31.2%, anxiety disorder: 7.5%, sleeping disorder: 43.0%). A change towards less exercise during the lockdown was significantly associated with higher levels of depression (t=5.269; β=0.077, p<.001), anxiety (t=3.397; β=0.055, p<.001) and insomnia (t=3.466; β=0.058; p<.001). Physical activity (PA)-related affect regulation enhanced the effect of exercise on mental health.

CONCLUSION

Results suggest a demand for measures which promote the maintenance of exercise during a pandemic and improve PA-related affect regulation to optimize effects of exercise on mental health.

Association between Occupational Noise and Vibration Exposure and Insomnia among Workers in Korea

Background: The effect of noise and vibration exposure on disturbed sleep has been investigated in the past. However, this study was carried out to investigate the relationship between workplace noise and vibration exposure with insomnia amongst representative Korean workers, both simultaneously and separately. Methods: Our research analyzed an overall population of 30,837 workers aged 15 years or older using data derived from the 5th Korean Working Conditions Survey (KWCS) conducted in 2017. Chi-squared tests and logistic regression were performed to investigate baseline characteristics and to quantify the association between workplace exposure to noise and vibration with insomnia. Relative excess risk due to interaction (RERI), attributable proportion (AP), and synergy index (S) were calculated to measure interactions between simultaneous noise and vibration exposure with insomnia. Results: The prevalence of those who reported insomnia was 18.3% of the general population. Among men and women, insomnia in those who were exposed to noise only was 13.9% and 18.3%, respectively, and in those who were exposed to vibration only, it was 23.9% in males and 26.4% in females. Insomnia in those who were exposed to both noise and vibration simultaneously was 20.5% and 41.2% in men and women, respectively. The odds ratio (OR) of insomnia due to noise exposure was 1.10 and 1.07 in men and women, respectively. OR of vibration exposure was 1.84 in men and 1.58 in women. For noise plus vibration exposure OR was 1.83 in men and 3.14 in female workers, where the synergistic effect of noise and vibration exposure could be seen. The association between the varying degree of simultaneous noise plus vibration exposure with insomnia showed a dose–response relationship. The interaction measures showed a synergistic effect of simultaneous exposure in women but not in men. Conclusion: Our study revealed an association between occupational noise and vibration exposure and insomnia, both individually and simultaneously. Additional studies and research are required to further comprehend this relationship.
