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.
