Incremental advantage of extraversion and neuroticism facets in predicting state work engagement

Abstract We extend the literature on personality dynamics and state work engagement by examining whether facets of state extraversion and neuroticism incrementally predict state work engagement beyond state domain personality (and other conceptually related covariates). This research contributes to the literature on state engagement and state personality by highlighting the dynamic and unique predictive potential of particular state facets for day-to-day engagement and its respective dimensions. Using a daily diary design, we collected data from 95 full-time employees over the course of 10 workdays (804 daily observations). Results indicated that state extraversion and neuroticism facets were related to overall state work engagement and that the facets predicted both broad and narrow (i.e., dimensions of) state work engagement beyond state domain personality. Specifically, state assertiveness predicted state work engagement beyond lagged engagement, state extraversion, and state positive affect. Similarly, state anxiety predicted state work engagement beyond lagged engagement, state neuroticism, and state negative affect. These findings further support the idea that state personality has predictive value for important dynamic workplace outcomes and extends this conclusion to state personality facets.
