| The present study investigated the relative effectiveness of facilitator, peer, and self appraisals for increasing the effective performance of 30 MBA students as defined by behaviour and grade point average (GPA). Behaviour was measured using a behavioural observation scale (BOS) derived from a job analysis. Repeated measures ANOVA revealed a main effect for source of appraisal on BOS and appraisal source credibility. Planned comparisons indicated that facilitator appraisals resulted in a higher BOS score than peer appraisals, and a marginally higher BOS score than self appraisals. Facilitators had higher credibility than peer or self appraisers. Appraisal source credibility, self-efficacy, outcome expectancy, and outcome valence, however, did not mediate the appraisal - performance relationship. There were no significant differences among the appraisal conditions on GPA. |
