The impact of SARS-CoV-2 on the mental health of healthcare workers in a hospital setting-A Systematic Review.

Abstract: Objectives The SARS-CoV-2 global pandemic has subjected healthcare workers (HCWs) to high risk of infection through direct workplace exposure, coupled with increased workload and psychological stress. This review aims to determine the impact of SARS-CoV-2 on mental health outcomes of hospital-based HCWs and formulate recommendations for future action. Methods A systematic review was performed between 31st December 2019 and 17th June 2020 through Ovid Medline and Embase databases (PROSPERO ID CRD42020181204). Studies were included for review if they investigated the impact of SARS-CoV-2 on mental health outcomes of hospital-based HCWs and used validated psychiatric scoring tools. Prevalence of ICD-10 classified psychiatric disorders was the primary outcome measure. Results The initial search returned 436 articles. Forty-four studies were included in final analysis, with a total of 69,499 subjects. Prevalence ranges of six mental health outcomes were identified: depression 13.5%-44.7%; anxiety 12.3%-35.6%; acute stress reaction 5.2%-32.9%; post-traumatic stress disorder 7.4%-37.4%; insomnia 33.8%-36.1%; and occupational burnout 3.1%-43.0%. Direct exposure to SARS-CoV-2 patients was the most common risk factor identified for all mental health outcomes except occupational burnout. Nurses, frontline HCWs, and HCWs with low social support and fewer years of working experience reported the worst outcomes. Conclusion The SARS-CoV-2 pandemic has significantly impacted the mental health of HCWs. Frontline staff demonstrate worse mental health outcomes. Hospitals should be staffed to meet service provision requirements and to mitigate the impact onmental health. This can be improved with access to rapid-response psychiatric teams and should be continually monitored throughout the pandemic and beyond its conclusion.

Leader-member exchange theory and research : accomplishments and future challenges

Abstract: In the Leader-Member Exchange (LMX) theory of leadership, the quality of the exchange relationship between a leader and a particular member of a work unit, team or organization is the basic unit of analysis (dyad). In this article, we try to answer the question whether research on the various aspects of the exchange processes between leaders and their subordinates is consistent with the theoretical underpinnings of LMX theory. Our focus is on the similarities and differences between the theoretical assumptions of LMX theory and the way the core concepts are elaborated in empirical studies. Although LMX theory has resulted in a number of useful accomplishments, both theoretical and practical, it still faces a number of challenges. The main challenges are to carry out a thorough and consistent refinement of the measuring instruments used, and to gain more insight into the mutual behaviours, attributions, and evaluations which facilitate or inhibit the development of high-quality working relationships.

Who killed my relative? police officers' ability to detect real-life high-stake lies

Abstract: The present experiment examined the ability of fifty-two uniformed police officers to detect deception. The experiment differed from previous experiments into detecting deceit because of its high stake lies scenario. The judges were exposed to videotaped press conferences of people who were asking the general public for help in finding their relatives or the murderers of their relatives. They all lied during these press conferences and they all have been found guilty of killing their own relatives. The judges did not perform better than could be expected by chance. Additional analyses showed that accuracy was unrelated to confidence, age, years of job experience in the police force, or level of experience in interviewing suspects. There was, however, a significant positive correlation between having experience in interviewing suspects and being confident in detecting deception. Finally, men were better at detecting deception than women.

The theory-practice gap in nursing: from research-based practice to practitioner-based research.

Abstract: The aim of nursing research is generally agreed to be the generation of knowledge, and whilst this is a relevant aim in theory-based disciplines such as sociology, the primary concern of nursing is with practice. Using examples drawn mainly from the field of mental health, it will be argued in this paper that the application of generalizable, research-based knowledge to individual, unique, person-centred practice, the so-called 'research-based practice' advocated by the Department of Health, is one of the main causes of the theory-practice gap. It will be further suggested that nursing requires a paradigm of clinical research which focuses on the individual therapeutic encounter in order to complement the existing sociological paradigm of theoretical research which is best suited to the generation of generalizable knowledge and theory. The paper will conclude by suggesting that such a clinically based research paradigm must not only focus on the individual nurse-patient relationship, but that it must be carried out by the nurse herself. Clinical research, if it is to make a difference to practice, must therefore be practitioner-based research.
