I am not aware of an updated version; only of the Spreitzer 1995 scale.
However, Spreitzer is a RG member. You could try asking the original author:
Spreitzer, G. M. (1995). Psychological empowerment in the workplace: Dimensions, measurement, and validation. Academy of management Journal, 38(5), 1442-1465.
If you are unable to make contact, there have been various translations of the scale (examples below). If no RG members supply an updated scale in response to your question, these authors might be worth contacting on RG, for their expertise on this matter:
Hochwälder, J., & Brucefors, A. B. (2005). A psychometric assessment of a Swedish translation of Spreitzer's empowerment scale. Scandinavian journal of psychology, 46(6), 521-529.
Hochwälder, J. (2006). A psychometric assessment of a Swedish translation of Shafer's personality scale. Scandinavian journal of psychology, 47(6), 523-530.
Uner, S., & Turan, S. (2010). The construct validity and reliability of the Turkish version of Spreitzer's psychological empowerment scale. BMC public health, 10(1), 1.
Reham, since this instrument was used in many published studies, you can use it in your research as well:
Connolly, M., Jacobs, S., & Scott, K. (2018). Clinical leadership, structural empowerment and psychological empowerment of registered nurses working in an emergency department. Journal of nursing management, 26(7), 881-887.
