The effectiveness of managerial leadership development programs: A meta‐analysis of studies from 1982 to 2001

TLDR

Methodological and conceptual differences in Burke and Day's meta‑analysis on managerial training make historical comparisons risky. The study integrated 83 training intervention studies from 1982 to 2001 using meta‑analysis to determine their effectiveness in enhancing performance, knowledge, and expertise at individual, team, or organizational levels. The meta‑analysis grouped studies by research design and treated each intervention outcome as a unit of analysis. Effect sizes ranged from .96 to 1.37 for knowledge, .35 to 1.01 for expertise, and .39 for system outcomes, indicating that knowledge interventions were more effective than earlier meta‑analyses and that practitioners can achieve substantial improvements in knowledge and skills when interventions are matched to leaders.

Abstract

Abstract Eighty‐three studies from 1982 to 2001 with formal training interventions were integrated via meta‐analytic techniques to determine the effectiveness of interventions in their enhancement of performance, knowledge, and expertise at the individual, team or group, or organizational level. The studies were separated by research design, with the outcome measure of the intervention as the unit of analysis. The effect size for knowledge outcomes ranged from .96 to 1.37; expertise outcomes from .35 to 1.01; and system outcomes averaged .39. Interventions with knowledge outcomes were found to be more effective than in the Burke and Day (1986) meta‐analysis, with the most effective interventions using a single group pretest‐posttest research design. Methodological and conceptual differences in Burke and Day's meta‐analysis on the effectiveness of managerial training make historical comparisons risky. The data suggest that practitioners can attain substantial improvements in both knowledge and skills if sufficient front‐end analysis is conducted to assure that the right development is offered to the right leaders.
