opportunities were significantly correlated with education, with each of the four career growth factors and to affective and normative organizational commitment, but not to continuance commitment. Given these associations, perceived opportunities and the demographic variables were used as controls in the remaining analyses.
Regression analysis
Regression analysis was used to investigate the influence of career growth on each of the separate forms of organizational commitment. For each of the three forms of commitment, the control variables were entered in the first step. The career growth factors were subsequently entered into each model in steps two and three. Step 2 added the two aspects of career growth that deal with personal development, career goal progress and professional ability development, while step 3 added the degree to which organizations followed through with appropriate rewards, promotion speed and remuneration growth. Doing this allows us to assess the role of organizational reward follow-up on organizational commitment over and above that achieved through personal development activities. Finally, the two-way interactions among the four career growth factors were entered in step 4 to test the exploratory hypothesis that combining career growth factors can enhance organizational commitment. Table 3 shows the regression results using standardized beta coefficients.
