This article reports a field study testing the relationship between individuals’ constructive-development level and their sources of work motivation. Constructive development was assessed using the Subject–Object Interview for 53 community and educational leaders. Motivation was assessed using the Motivation Sources Inventory. Results indicated that constructive-development progression was significantly related to instrumental motivation. No other significant relationships were found, indicating that the other four sources of work motivation exist independent of individuals’ constructive development. Implications for research and practice are addressed.
