Recovery, Work Engagement, and Proactive Behavior: A New Look at the Interface Between Nonwork and Work

Abstract: This study examined work-related outcomes of recovery during leisure time. A total of 147 employees completed a questionnaire and a daily survey over a period of 5 consecutive work days. Multilevel analyses showed that day-level recovery was positively related to day-level work engagement and day-level proactive behavior (personal initiative, pursuit of learning) during the subsequent work day. The data suggest considerable daily fluctuations in behavior and attitudes at work, with evidence that these are related to prior experience and opportunity for recovery in the nonwork domain.

The Recovery Experience Questionnaire: Development and validation of a measure for assessing recuperation and unwinding from work.

Abstract: Drawing on the mood regulation and job-stress recovery literature, four self-report measures for assessing how individuals unwind and recuperate from work during leisure time were developed (Study 1). Confirmatory factor analyses with a calibration and a cross-validation sample (total N 930) showed that four recovery experiences can be differentiated: psychological detachment from work, relaxation, mastery, and control (Study 2). Examination of the nomological net in a subsample of Study 2 (N 271) revealed moderate relations of the recovery experiences with measures of job stressors and psychological well-being; relations with coping and personality variables were generally low (Study 3). Potential applications for the future use of these short 4-item measures in longitudinal and diary research are discussed.

Recovery as an explanatory mechanism in the relation between acute stress reactions and chronic health impairment.

Abstract: This contribution aims at shedding light on the mechanisms that may underlie the relationship between acute reactions to stressful work characteristics and employee health in the long run. Recovery, a process of psychophysiological unwinding after effort expenditure, is considered a vital link in this relationship. This link is explained on the basis of assumptions from theories on effort, recovery, and sustained activation. It is argued that recovery after work (external recovery) is particularly necessitated when recovery opportunities during worktime (internal recovery) are insufficient. It is further argued that two conditions may impede the recovery process by sustaining physiological activation, prolonged exposure to work demands (working long hours) and cognitive stress-related processes (such as rumination). These theoretical assumptions are substantiated by empirical support from previous laboratory and field research. It is concluded that the chronic situation of sustained physiological activation and incomplete recovery is an important pathway to chronic health impairment.

Diary Studies in Organizational Research: An Introduction and Some Practical Recommendations

Abstract: In recent years, researchers in work and organizational psychology have increasingly become interested in short-term processes and everyday experiences of working individuals. Diaries provide the necessary means to examine these processes. Although diary studies have become more popular in recent years, researchers not familiar with this method still find it difficult to get access to the required knowledge. In this paper, we provide an introduction to this method of data collection. Using two diary study examples, we discuss methodological issues researchers face when planning a diary study, examine recent methodological developments, and give practical recommendations. Topics covered include different types of diary studies, the research questions to be examined, compliance and the issue of missing data, sample size, and issues of analyses.

Recovery from job stress: The stressor-detachment model as an integrative framework

Abstract: Summary This paper reviews empirical evidence on psychological detachment from work during nonwork time. Psychological detachment as a core recovery experience refers to refraining from job-related activities and thoughts during nonwork time; it implies to mentally disengage from one's job while being away from work. Using the stressor-detachment model as an organizing framework, we describe findings from between-person and within-person studies, relying on cross-sectional, longitudinal, and daily-diary designs. Overall, research shows that job stressors, particularly workload, predict low levels of psychological detachment. A lack of detachment in turn predicts high strain levels and poor individual well-being (e.g., burnout and lower life satisfaction). Psychological detachment seems to be both a mediator and a moderator in the relationship between job stressors on the one hand and strain and poor well-being on the other hand. We propose possible extensions of the stressor-detachment model by suggesting moderator variables grounded in the transactional stress model. We further discuss avenues for future research and offer practical implications. Copyright © 2014 John Wiley & Sons, Ltd.

Clinical course and risk factors for mortality of adult inpatients with COVID-19 in Wuhan, China: a retrospective cohort study

Abstract: Summary Background Since December, 2019, Wuhan, China, has experienced an outbreak of coronavirus disease 2019 (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Epidemiological and clinical characteristics of patients with COVID-19 have been reported but risk factors for mortality and a detailed clinical course of illness, including viral shedding, have not been well described. Methods In this retrospective, multicentre cohort study, we included all adult inpatients (≥18 years old) with laboratory-confirmed COVID-19 from Jinyintan Hospital and Wuhan Pulmonary Hospital (Wuhan, China) who had been discharged or had died by Jan 31, 2020. Demographic, clinical, treatment, and laboratory data, including serial samples for viral RNA detection, were extracted from electronic medical records and compared between survivors and non-survivors. We used univariable and multivariable logistic regression methods to explore the risk factors associated with in-hospital death. Findings 191 patients (135 from Jinyintan Hospital and 56 from Wuhan Pulmonary Hospital) were included in this study, of whom 137 were discharged and 54 died in hospital. 91 (48%) patients had a comorbidity, with hypertension being the most common (58 [30%] patients), followed by diabetes (36 [19%] patients) and coronary heart disease (15 [8%] patients). Multivariable regression showed increasing odds of in-hospital death associated with older age (odds ratio 1·10, 95% CI 1·03–1·17, per year increase; p=0·0043), higher Sequential Organ Failure Assessment (SOFA) score (5·65, 2·61–12·23; p Interpretation The potential risk factors of older age, high SOFA score, and d-dimer greater than 1 μg/mL could help clinicians to identify patients with poor prognosis at an early stage. Prolonged viral shedding provides the rationale for a strategy of isolation of infected patients and optimal antiviral interventions in the future.

Antecedents and consequences of employee engagement

Abstract: Purpose – Employee engagement has become a hot topic in recent years among consulting firms and in the popular business press. However, employee engagement has rarely been studied in the academic literature and relatively little is known about its antecedents and consequences. The purpose of this study was to test a model of the antecedents and consequences of job and organization engagements based on social exchange theory.Design/methodology/approach – A survey was completed by 102 employees working in a variety of jobs and organizations. The average age was 34 and 60 percent were female. Participants had been in their current job for an average of four years, in their organization an average of five years, and had on average 12 years of work experience. The survey included measures of job and organization engagement as well as the antecedents and consequences of engagement.Findings – Results indicate that there is a meaningful difference between job and organization engagements and that perceived organi...
