In the March 1996 issue of "Individual Psychology," (1994 NASAP Convention Keynote Speech) Powers and Griffin declare that "... Dreikurs had once publicly declared his own theoretical position to be between that of Adler and that of Karen Horney." They go on to state that "...Dreikurs was an independent thinker, with original theoretical ideas, and that not all of Dreikurs' ideas were in agreement with Adler's ideas."
Sophia de Vries and Anthony Bruck, both of whom studied with Adler, recognized Dreikurs as an outstanding diagnostician and parent educator, but they believed that his therapeutic technique and style deviated sharply from Adler's original approach. They recommended that students and clinicians rely primarily on Adler's original writings to gain the clearest and deepest understanding of Adlerian theory and practice.
