Transforming Leadership Study


Dr. L wrote his Ph.D. Dissertation on the subject of transforming leadership. He was interested in the impact that a modern leadership style has on follower performance and job satisfaction. To study this relationship, he used the meta-analysis research method.

Meta-analysis allows a researcher to combine the numerical findings of a variety of original studies into an aggregate measure. Because of the much larger sample size that results from combining multiple studies, the aggregate measure (called an effect size statistic) is a much better statistical estimator of the phenomenon in question.

The Abstract from Dr. L's Dissertation provides more information:

To facilitate the transition to more collaborative forms of leadership, this study examined the impact of leaders who use modern styles of leadership, characterized as visionary, charismatic, or transformational, to motivate their followers to achieve higher levels of performance and job satisfaction. Although the new millennium requires leaders to engage followers in the change process, many leaders seem reluctant to embrace modern methods of transforming leadership despite evidence of their effectiveness.

The researcher used meta-analysis, a research method useful for combining the quantitative findings of a number of primary research studies, to synthesize the findings of 7 experiments and 27 correlational studies of transforming leadership published in the past 15 years. The meta-analysis provided effect size estimates of the relationship between leadership style and two follower outcomes, performance and satisfaction. The meta-analysis also provided estimates of the magnitude and statistical significance of four factors that prior research indicated might affect these relationships: (a) research design (i.e., experimental or correlational study); (b) subject of analysis (i.e., individual or group); (c) type of participant (i.e., student, military, or worker); and (d) type of performance measurement (i.e., objective or subjective).

Based on the correlational data from the studies in the research sample, the meta-analysis synthesis yielded medium to strong positive correlations between a transforming leadership style and follower performance and satisfaction. Smaller, but statistically significant, positive effect sizes from the experiments included in the study supported these findings. The four study characteristics explained little of the residual variance in the data. Research design and participant type explained a small, but statistically significant, amount of the unexplained variation. However, the impact of subject of analysis and type of performance measurement on the residual variance in the data was not statistically significant.

The study concludes with a series of recommendations based on these findings for further study and for proactive leadership actions to implement transforming leadership in organizations and thereby effect positive social change.
