The Measurement of Organizational and Professional Commitment: An Examination
of the Psychometric Properties of Two Commonly Used Instruments
Dennis M. Bline, Dennis Duchon and Wilda F. Meixner
This study investigates the Porter et al.  measure of organizational
commitment and the Aranya et al.  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.
