Work-related stress is a prevalent condition in the nursing profession, and its influence may vary according to changeable individual and situational factors. It is, therefore, important to investigate the real-time momentary changes in these factors and their relationship to emotional exhaustion experienced by nurses. We aim to analyse how their perceptions of demand, control, effort and reward change according to the task performed through real-time assessment and interact with the emotional exhaustion level of ward nurses. The research design was longitudinal. A three-level hierarchical model with a repeated measures design was used to assess the momentary self-reports of 96 hospital ward nurses, completed using a smartphone programmed with random alarms. Findings show that demand, effort, and control appraisals depend on the task performed. The task appraised as most demanding, effortful, and controllable was direct care. Reward appraisal depends on the task performed and personal variables, i.e. emotional exhaustion. The situations perceived as more rewarding were rest and direct care. Momentary hedonic tone can be explained by the task performed, demand, reward, emotional exhaustion and by the interaction between emotional exhaustion and demand appraisal. Momentary fatigue can be explained by the task performed, demand, reward, and the emotional exhaustion. This study highlights the importance of using momentary measures to understand complex and changeable inter-relationships. While also clarifying the targets of intervention programmes aimed at preventing burnout within the nursing profession.

Positive organizational psychology (POP) is a research area that focuses on the positive aspects of optimal functioning at work. Although consolidated and with a large volume of publications, no bibliometric analysis has been performed that allows knowing its high-level structure, developments, and distribution of knowledge since its origins. The objective is to analyze the 7181 articles published in POP on the Web of Science Core Collection (WoSCC). A retrospective bibliometric analysis and science mapping were performed. The title, authors, institutions, countries, scientific categories, journals, keywords, year, and citations were extracted from WoSCC. Impact factor, quartile, and country were collected from Journal Citation Reports (JCR) 2019. Authors were classified according to the proposal of Crane, and Bradford’s law was calculated. The results show that it is an area with more than 100 years of experience, divided into three stages of different productivity and visibility, highlighting a decrease in its visibility in recent years. With a multidisciplinary and international interest, psychology and business and economics stand out, especially in countries such as the United States, the United Kingdom, and the Netherlands. Four popular study topics emerged: well-being at work, positive leadership, work engagement, and psychological capital.

How does the experience of flow among nurses influences their health? This question is addressed on the basis of a model of flow, stress, burnout, and coping. The results indicate that promoting flow can be a way to enhance the health of ward nurses in a hospital work context.

Background:: Donaldson & Donaldson (2021b) developed a scale to assess Positive Functioning at Work, adding four new blocks to strengthen the original PERMA framework in the workplace. The aim of the present study was to validate this scale in a Spanish sample. Method:: 698 Spanish workers participated, 59% were women and 41% were men, 71.6% were employees and 71.2% belonged to the basic worker level. Results:: Confirmatory Factor Analysis showed a good fit of the nine-factor model (χ/df = 2.441; RMSEA = .056, 90% IC (.049, .063); SRMR =. 062; CFI = .926; TLI = .916), the bifactor model (χ/df = 1.703; RMSEA = .044, 90% CI [.037, .050]; SRMR = .050; CFI = .959; TLI = .952) and the ESEM model (χ/df = 1.736; RMSEA = .041, 90% CI [.033, .049]; SRMR = .017; CFI = .976; TLI = .942). The adapted scale also demonstrated good internal consistency, with a Cronbach’s α of .90 for the scale, and evidence of discriminant, criterion, predictive, and incremental validity with other well-being and performance measures, as well as measurement invariance across educational levels. Conclusions:: This scale provides a comprehensive measurement tool that can help in the design of workplace programs and interventions.

Multiple Chemical Sensitivity (MCS) is an acquired disease which etiology remains unknown. It is characterized by the development of sensitivity to certain chemical products.Most of the hypotheses formulated to explain the syndrome associate it to a previous exposition to some kind of volatile chemical. University researchers in chemical laboratories suffer a phenomenon of multi-exposition to chemical agents at low concentration during long periods of time although in an irregular form. Many of these chemical agents have similar properties to those suspicious of causing MCS. This article studies the prevalence of MCS in laboratory researchers. The study group is university researchers in chemical laboratories. The control group was obtained from administrative personnel who work in the same universities and therefore, are not exposed to chemical products from the laboratories, but have the same exposition to the rest of environmental polluting agents from the area and from the buildings of the university. In this study, it is used the Quick Environmental Exposure and Sensitivity Inventory (QEESI) (sensitivity of 92%/specificity of 95%). The results showed that the prevalence of MCS for the university researchers is not related to exposition by inhalation to multiple chemical agents, at low concentration. The results disagree with one of the main etiological hypotheses of MCS, which is based on the existence of hypersensitive people, who presents a response after prolonged expositions to very low concentrations during a long period of time.
