Evaluating the Constructvalidity of Work Commitment Measures: A Confirmatory Factor Model

A detailed description of the use of confirmatory factor analysis when evaluating the construct validity of work commitment measures is provided Using a random sample of 841 licensed pharmacists, evidence for the convergent and discriminant validity of the measures of career commitment, organizational commitment, career withdrawal intention, and job withdrawal intention was obtained. The factor loadings, error variances, and fit indices all indicated an adequate fit. The psychometric properties of each scale indicated that the scale items had high reliabilities. The results of these analyses indicate that confirmatory factor analysis provides an alternative to exploratory analyses when determining the construct validity of work commitment concept measures. Continued use of these scales is recommended in other professional groups so that these results may be replicated.
