A Study of the Psychometric Properties of the Managerial Skill Scales of the Survey of Management Practices
Frank Shipper (1995), Vol. 55, pp. 468-479. Educational and Psychological Measurement.
Much interest in managerial skills has been generated recently. However, most of the
questionnaires on managerial skills have focused on frequency and not competency. Thus
the purpose of this study is to test the psychometric properties of the managerial
skill scales of the Survey of Management Practices, which is purported to measure the
competency of individuals on 11 managerial skills. Overall, the results suggest that
the managerial skill scales of this instrument have the psychometric properties of
internal consistency, inter-rater agreement, construct validity, divergent discriminate
validity, and both internal and external criterion validity. Some modifications for
improvement are nevertheless suggested.
