We examined emotional stability, ambition (an aspect of extraversion), and openness as predictors of adaptive performance at work, based on the evolutionary relevance of these traits to human adaptation to novel environments. A meta-analysis on 71 independent samples (N = 7,535) demonstrated that emotional stability and ambition are both related to overall adaptive performance. Openness, however, does not contribute to the prediction of adaptive performance. Analysis of predictor importance suggests that ambition is the most important predictor for proactive forms of adaptive performance, whereas emotional stability is the most important predictor for reactive forms of adaptive performance. Job level (managers vs. employees) moderates the effects of personality traits: Ambition and emotional stability exert stronger effects on adaptive performance for managers as compared to employees.
Prior research on work ethic ideology has tended to neglect the multidimensional nature of such ideology. To examine how different facets of work ethic ideology may be rooted in the basic personality construct of conscientiousness, 299 Americans completed a 133-item online survey that contained six facets of conscientiousness and seven different dimensions of work ethic ideology. Multiple regression analyses revealed that the conscientiousness facets of dutifulness and achievement striving were the two most consistent predictors of seven dimensions of work ethic ideology. Subsequent dominance analyses suggested that achievement striving, followed by dutifulness, tended to predict the most work ethic dimensions. Discussion focuses on the theoretical importance of using work ethic dimensions rather than global work ethic scores in future research.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
