Work-Related Stress Among Chefs: A Predictive Model of Health Complaints

Factor structure and measurement invariance of the psychosocial risk factors inventory of NOM-035-STPS-2018

The primary objective of this study was to analyze the psychometric properties of the Inventory for the Identification and Analysis of Psychosocial Risk Factors (IIA-PRF) of Reference Guide III proposed in NOM-035-STPS-2018. A total of 2,149 workers in Baja California, Mexico's industrial and education-government sectors, were administered an online inventory version. Preliminary analyses were performed, as well as a Confirmatory Factor Analysis (CFA) based on two models proposed by the standard itself: an eight-factor model (8-FM) and a four-factor model (4-FM). Likewise, based on the results and with the recommendations of the specialists, a threefactor model (3-FM) was proposed. In addition, nested model sequencing methods were subsequently applied to validate the invariance between the origin of the activity. The dimensionality of 3-FM was found to have adequate fit values according to a-priori established criteria. It is concluded that the IIAPRF does not have the reliability and validity parameters necessary to support interpretations, uses and consequences based on the theoretical structure established by NOM-035-STPS-2018 and that, although the 3-FM presents better reliability and validity indices, it is not invariant in terms of the origin of the activity. Finally, we discuss the implications and recommend reviewing and adjusting the design of the IIAPRF items to extend the measurement of invariance to other groups of relevance for decision making in the improvement of the work environment.

The Health Cost of Organizational Citizenship Behavior: Does Health-Promoting Leadership Matter?

Previous research has mainly focused on the positive effects of organizational citizenship behavior (OCB). This study questions the positive impact of OCB, arguing that there is a health cost of OCB. Based on the conservation of resource theory, this study expects that OCB triggers citizenship fatigue, which, in turn, negatively affects employees' health and results in health complaints. This study also seeks to find a moderator (health-promoting leadership) that could mitigate the negative effects of citizenship fatigue (caused by engaging in OCB) on health complaints. To test our predictions, we collected three-wave data from 207 leader-subordinate dyads. The results of regression analyses show that OCB is positively related to employees' health complaints, which is mediated by citizenship fatigue. Health-promoting leadership weakens the positive relationship between citizenship fatigue and health complaints, thus negatively moderating the indirect relationship between OCB and health complaints via citizenship fatigue. This study provides theoretical and practical implications for future research directions.

Physical and psychological stress along with candle fumes induced-cardiopulmonary injury mimicking restaurant kitchen workers

Restaurant kitchens are work areas where involve strict and hierarchal environments that promote opportunity for bullying and workplace aggression and violence. These physical and psychological stress and fumes ultimately trigger severe occupational stress by disrupting the body's homeostasis that might induce cardiopulmonary injury. The study aimed to investigate the physical and psychological stress and candle fumes on cardiopulmonary injury in an animal model mimicking a restaurant kitchen worker. Social disruption stress (SDR) mice were exposed to scented candle fumes (4.5 h/d, 5 d/wk) in an exposure chamber for 8 weeks. Exposure to burning scented candles failed to reduce serum corticosterone level and increased proinflammatory cytokines levels and NF-ƙB activity in the lung. In addition, burning scented candle fumes synergistically increased SDR-induced serum LDH, CPK, CKMB levels, proinflammatory cytokines production as well as NF-ƙB activation in the lung and heart. Further, cardiac HIF-1α and BNP levels were also increased. We conclude that the physical and psychological stress along with candle fumes might induce cardiopulmonary injury in mice. These results could be extrapolated to restaurant kitchen workers.
