Threat appraisals and challenge appraisals could influence job performance distinctively.[9] As for adaptive performance, the more challenging (i.e., the less threatening) one’s stress appraisals are, the more adaptive performance he/she would have.[10] This relationship is mediated by self-efficacy, which is a belief about one’s capacities for certain tasks. Challenging rather than threatening appraisals would lead to higher levels of self-efficacy, and thus benefit individuals’ adaptive performance.
