Appraisal theory assumes that the individual variability of emotional reactions to the same situation is due to individual differences in appraisal. However, the question of how interindividual differences in appraisal come about has been rarely formally addressed. We focus on one of the central dimensions of appraisal—problem-focused coping potential—and attempt to explain individual differences in appraisals along this dimension using self-efficacy theory. We integrate outcome expectancies, self-efficacy expectations, and problem-focused coping potential into a single framework and outline their personality antecedents. (...) Using generalized self-efficacy beliefs as an example, we then discuss the mechanisms underlying the effects of personality dispositions on appraisal and the conditions that moderate their influence. We conclude with the implications for theory, research, and practice. (shrink)
