The across-time associations of the five-factor model of personality with vigor and its facets using the bifactor model.

We tested hypothesized across-time associations of personality traits with the affective state of global vigor and its physical, emotional, and cognitive facets. The study was carried out in the context of work, where vigor represents a discrete, positive affective response to one's ongoing interactions with specific elements of the work environment. Our model was based on the bifactor approach to modeling second-order constructs in structural equation modeling. Data were gathered from 1,217 reportedly healthy respondents who underwent a periodical health examination at Time 1 (T1) and Time 2 (T2), about 24 months apart. We found that, independent of T1 and T2 global vigor, agreeableness and conscientiousness predicted both T1 and T2 levels of vigor's emotional facet, and openness predicted vigor's cognitive facet at both T1 and T2.
