Dr. McClanahan has designed and implemented a study at Insight’s residential treatment centers in Illinois to elucidate factors that predict positive responses to treatment, including therapeutic alliance, motivation, DBT skills acquisition and ERP engagement to outcomes.  The results of this study have important implications for the design and implementation of residential treatment services at Insight and elsewhere in the field.  Additionally, Dr. McClanahan recently spearheaded a research collaboration with Dr. Daniel Le Grange examining the inclusion of DBT in certain cases of FBT in order to improve treatment outcomes.

Dr. McClanahan has also proven to be an advocate for mental health treatment and Chicago eating disorder treatment in particular.  In 2010 she raised local awareness of discrepancies in an insurance company’s interpretation of parity laws and was instrumental in making changes on a state level to ensure proper care for Illinois residents.
