Because appraisal-related interactions between supervisors and employees ma
y influence more than task performance, the authors considered the potentia
l effects of social and interpersonal processes in performance appraisal on
contextual performance. They hypothesized that performance appraisal proce
ss and system facets were associated with employees' contextual performance
as well as with their perceptions of appraisal accuracy. After controlling
relevant variables, they found that appraisal process facets explained var
iance in contextual performance and perceived accuracy beyond that accounte
d for by the system facets. However, when the order of entry for the proces
s and system variable sets was reversed, only for perceived appraisal accur
acy, as hypothesized, did the system facets account for variance beyond tha
t explained by the appraisal process facets.
