Professionalization is an important issue in many all-volunteer nonprofit organizations (e.g. recreational sports clubs). Therefore, this study relied on the competing values framework and self-determination theory to investigate whether a newly developed intervention can effectively strengthen the management processes and leadership styles in all-volunteer sports clubs.
For this purpose, a rigorous non-equivalent pre-test post-test control group design was used. The intervention involved two sessions organized in sports clubs in which internal stakeholders (e.g. board members, coaches, volunteers) were invited to discuss change initiatives aimed at enhancing the organizational processes.
An effect on both the management processes and leadership styles was found. As for the management processes, the intervention had an impact on the internal processes, with especially the development of an internal communication plan and the annual assessment of the organization's operations being promoted by the intervention. Regarding the leadership styles, the intervention had an effect on the controlling and chaotic leadership style, with leaders becoming less chaotic and controlling in situations in which (respectively) the business plan was established and the tasks were distributed within the organization.
This intervention study adopted an innovative approach to organizational intervention research by focusing on the enhancement of both the management processes and the leadership styles. Its principles are also relevant and valuable to organizations operating in other organizational contexts.
