The multiple face(t)s of state conscientiousness: Predicting task performance and organizational citizenship behavior

•Daily overall C positively predicts daily OCB and task performance.•Daily task performance is also predicted by daily self-discipline and deliberation.•The C facets do not predict daily OCB above and beyond general C.•Our findings suggest that state C fails to capture aspects related to self-control.

Previous studies have shown that conscientiousness facets incrementally predict performance above and beyond trait conscientiousness. In the present paper we investigate whether this finding also holds at the daily level. We conducted a ten-day experience sampling study assessing state conscientiousness in the morning and task performance and organizational citizenship behavior (OCB) in the afternoon. Using multilevel bi-factor modeling we show that general state conscientiousness positively predicts both task performance and OCB. Moreover, self-discipline and deliberation showed incremental predictive validity above and beyond overall state conscientiousness in the prediction of daily task performance, whereas none of the state conscientiousness facets uniquely predicted daily OCB levels.
