Mediating effect of job crafting dimensions on influence of burnout at self-efficacy and performance: revisiting health-impairment process of JD-R theory in public administration.

Introduction: In recent years, job crafting has greatly interested Work and Organizational Psychology. Different research studies have shown its positive impact on people and organizational performance. However, it knows little about the differential effect of the two dimensions that make up this variable (prevention-focused and promotion-focused) and its role in the health-impairment spiral process of the job demand-resources theory (JD-R).

Leading the Challenge: Leader Support Modifies the Effect of Role Ambiguity on Engagement and Extra-Role Behaviors in Public Employees.

The assumption of new challenges and services to provide, and the evolution of new technologies in public administration, give employees an important perception of ambiguity when carrying out their work. Role ambiguity has been conceptualized as one of the main impeding demands at work with negative consequences. The objective of the present study is to analyze the moderating effect of the support by the department head in the negative influence of the role ambiguity on the engagement and the extra-role performance behaviors of the employees.

A critical appraisal of the prognostic predictive models for patients with sepsis: Which model can be applied in clinical practice?

Background: Sepsis is associated with high mortality and predictive models can help in clinical decision-making. The objective of this study was to carry out a systematic review of these models.

Methods: In 2019, we conducted a systematic review in MEDLINE and EMBASE (CDR42018111121:PROSPERO) of articles that developed predictive models for mortality in septic patients (inclusion criteria).

Positive Influence of Role Ambiguity on JD-R Motivational Process: The Moderating Effect of Performance Recognition.

Most previous research has shown the negative influence of role ambiguity on employes' motivational process. This has led to role ambiguity being perceived as a main hindrance demand in the workplace, with a negative effect on the Job Demands Resources (JD-R) model's motivational process. Recent theories propose that job demands can be perceived by employes as a challenge, rather than a hindrance.

Quality assessment of meta-analyses evaluating randomized clinical trials to improve the prognosis of septic shock: an overview of systematic reviews.

Clinical guidelines for the treatment of septic shock are based on the studies with the best scientific evidence, which are meta-analyses of clinical trials. However, these meta-analyses may have methodological limitations that prevent their conclusions from being extrapolated to routine clinical practice. Therefore, the objective of this study is to determine the quality of these meta-analyses through a systematic review.
