Research Interests: 

My research interests center around psychotherapy outcome and process and the broad question of “How do people change?” Much of my work is directed toward understanding barriers to change, both in and out of psychotherapy. These have usually been grouped under the general term “resistance.” I have reconceptualized resistance as ambivalence and have developed methods to help people resolve this ambivalence and move toward change. I think the focus on ambivalence is an important one, but I’m not sure. Sometimes I think it’s important and sometimes I don’t. I think I need help in resolving this ambivalence. I have incorporated Motivational Interviewing (MI) into my research. MI is an approach that has been to help people resolve ambivalence and to increase their internal motivation to change problem behaviors. Numerous studies have found that MI is effective with alcohol and drug problems. I have been interested in extending the scope of MI to other problems typically seen in clinical practice such as anxiety and mood disorders. Further, I am interested in developing measures of the process of change in MI. Finally, I am interested in the dissemination of knowledge from clinical psychology to the general public. Unfortunately, many laypersons hold myths about mental health that are contradicted by scientific findings of which they are unaware. I’m interested in studying barriers to such dissemination of such knowledge and ways to facilitate it.

I have been a scientist-practitioner for my entire career.  I value how science can inform practice and how practice can inform science.
