Abstract
The Education Participation Scale (EPS) (A-form) measures motivational orientations and consists of seven 6-item factors comprised of items inductively derived from adult education participants. The final 42 items were those that survived processes designed to examine the reliability and construct validity of the scale. To investigate concurrent validity, EPS (A-form) scores were correlated with EPS (F-form) scores. Predictive validity was examined by relating interview data and "estimates" to actual EPS scores. Responses from 845 subjects living in North America and Asia were entered into discriminant function equations where the combined EPS (A-form) scores successfully classified 60% of respondents into their gender, 25% into their age, and 65% into their ethnic groups. Coefricient alphas ranged from .76 to .91; the mean scale test/retest coefficient was .65. The EPS (A-form) appears to be psychometrically sound and the author suggests that the F-form now be retired.
