I like this one (from the exploration vs. exploitation literature):
Farmer, S. M., Yao, X., & Kung‐Mcintyre, K. (2011). The behavioral impact of entrepreneur identity aspiration and prior entrepreneurial experience. Entrepreneurship Theory and practice, 35(2), 245-273.
The items are contained. Furthermore, the GEM measures employee entrepreneural activity but i do not know the items. If you can manage to find them, drop a note :)
i found in the article thank Farmer, S. M., Yao, X., & Kung‐Mcintyre, K. (2011), creativity measurement not items for measure employees innovation performance.
