Abstract

This study investigates the Porter et al. (1974) measure of organizational commitment and the Aranya et al. (1981) measure of professional commitment to determine whether the scales are measuring different constructs. Psychometric properties of both measures are examined using data gathered in a sample of university faculty and a sample of state and local governmental accountants. Results of item analysis, factor analysis, internal consistency (alpha), and convergent and discriminant validity tests (correlation analysis) indicate that the two scales are indeed measuring different constructs and that the professional commitment scale appears to be a reliable measure.
