It was brought to our attention that one item in the NEO-FFI measure used in the above article was misplaced in the analyses of our study.1 The item in question was, in our analyses, in the extraversion scale, while it belonged to the agreeableness scale. When moved to the correct scale, all scales in the NEO-FFI consisted of 12 items. The Cronbach's alphas for the corrected scales of extraversion and agreeableness remained unchanged (α = 0.8 for both scales). In general, the effect sizes increased slightly in the new analyses with agreeableness showing the greatest increase and explaining 10% (vs 9%) of the variance in reward. Although most of the associations of extraversion and agreeableness with effort-reward imbalance and its components were somewhat stronger in the new analyses, some of the associations attenuated to nonsignificance. However, the decrease in significance was, in most cases, only one degree of significance.
Table 1 shows the correct results for the regression analyses between the Five-Factor Model traits and effort-reward imbalance and its components. The authors would like to apologize to the readers of this paper for any inconvenience caused by this error.
