Studied the meaning of Performance Failure Appraisal Inventory (PFAI; Conroy and others, 2002) by evaluating the comparability of PFAI factor structure over repeated assessments and the stability of the subscales over relatively brief intervals. Results for 356 college students generally show high stability for PFAI scores in long and short forms.…
