Doug Sprenkle Ph.D. of the Purdue University Marriage and Family Therapy program came and spoke to current Purdue University Calumet Marriage and Family masters students Friday, November 13th, 2009. Dr. Sprenkle introduced his work regarding the common factors found to be effective within therapy. Dr. Sprenkle introduced the difference between model-driven change and common factors change and made the argument that common factors have shown to be very effective in the treatment of clients. Among things he discussed was the importance of the therapist believing in the theory they are working within.He mentioned that often it does not matter the theoretical orientation but belief in the theory on part of the therapist. Furthermore, some of his findings highlighted the notion that individuals within therapy and therapists mention different parts of therapy as the turning point in producing change. Lastly, Dr. Sprenkle highlighted three important points within common factors: changing the feeling, changing the doing, and changing the thinking. These three processes help aid in slowing down the process with clients, having them take responsibility within their relationships, and gaining the ability to stay meta to self and other. PUC MFT students and faculty were honored to hear Dr. Sprenkle speak about his current research.
