The effect of a supervisory development program on leadership style

The purpose of this study was to investigate the effect of a supervisory development program on leadership style, conceptualized as the amount of consideration and structure demonstrated by supervisors. One hundred male supervisors of a government railways department were randomly selected and then assigned randomly to either receive training (n=50) or not to be trained (n=50). The program was a 22-week residential course, training participants in human relations and structuring skills. Measures of the supervisors' consideration and structure were obtained from 100 male subordinates of the supervisors 4 weeks prior to, and 2 months after, training. At pre- and post-test, supervisors in the experimental and control groups rated the amount of consideration and structure they felt they should use. Analysis of variance with significant interaction effects revealed that the training program enhanced self and subordinate-rated consideration and structure.
