I-E Locus of Control, Selected Edwards Personal Preference Scales and Task Persistence

Abstract

This study assessed scores of the Internal-External scale, and Edwards Personal Preference Schedule (EPPS) order, endurance, and autonomy scales in relation to subjects' willingness to persist through a two-part experimental design. Convergent validation of the Janis-Hovland self-esteem scale with the EPPS abasement scale was also attempted. Data showed EPPS order, endurance, and autonomy scales differentiated between “persistors” and “nonpersistors” whereas Internal-External scale scores did not. Also Janis-Hovland self-esteem scores correlated significantly and inversely with EPPS abasement scale scores.
