The book I'm Stuck, You're Stuck: Breakthrough to Better Work Relationships and Results by Discovering your DISC Behavioral Style by Tom Ritchey discusses the DISC model...It also includes the 28 question assessment.
I found I'm a High S, but I scored above 44 on D and i as well. I'm still not sure how a High S is resistant to change other than that change can elicit emotional reactions from co-workers that aren't always "happy" which in turn may lead to the High S to become resistant.
Anyway, it's a way to get a hold of the test and a fair explanation of the results.
