Heidi, the interest in change management has continued to grow over the decades. You may be interested in looking at Bovey and Hede's (2001) work on the impact of affective and cognitive processes in ascertaining people's resistance to change as well as Holt et al.'s (2007) study on developing a scale to measure people's readiness to embrace change. Interesting area of investigation.
