In recent years, the construct of work engagement as well as methods for its measurement have generated growing interest in the field of occupational psychology. In this study, we aim to contribute to the current work engagement literature by investigating the possible advantages of single-item measures of work engagement by analysing their psychometric feasibility. Testing the validity of a single-item measure tool within the framework of the Job Demands-Resources theory, we have found similar pattern of correlations of single-item measures of work engagement with exhaustion, disengagement, job resources and job demands as for the well-established multi-item measure the Utrecht Work Engagement Scale. The reliability of single-item measures tested with factor analysis and the attenuation formula was estimated to be in the range of between .60 and .70, the figure depending on the particulars of the estimation methods. Our findings provide an initial modicum of evidence that, if a research purpose requires it, or if the use of a multi-item measurement tool is overly restrictive or costly, then a single-item measure of work engagement could be effectively adopted.

We examined the role of work-related emotions and personal resources operationalised as psychological capital (PsyCap) in the relationship between events occurring at work and employees’ work engagement. Using affective events theory and broaden-and-build theory as theoretical frameworks, we theorise that the perceived frequency of positive and negative events at work and work engagement is mediated by positive and negative work-related emotions and moderated by PsyCap. The results of path analysis on a sample of US and Polish employees showed that PsyCap moderated the relationship between the perceived frequency of negative work events and negative work-related emotions, however, we also found culture-specific effects of PsyCap. Our study contributes to the human resource development (HRD) literature by providing evidence of the role of personal resources in the event–emotion–engagement process in the workplace. Also, our findings deepen the understanding of HR developers in multinational organisations and provide suggestions on how they can implement PsyCap trainings based on culture-specific work environment.
