Thanks to both of you! Presently, I am a 3rd year grad student, master's degree in mental health counseling. For my research and program evaluation class, I proposed a research study on the effectiveness of DBT in the treatment of sports-related traumatic brain injury sequelae (specifically, aggression and impulsiveness). I know that there is ample evidence which suggests DBT is effective in treating these symptoms in patients with a diagnosis of borderline personality disorder; the research from SPECT scans of BPD patients show similar brain structure and function to people who have sustained injuries to areas of the brain controlling aggression and impulsivity. I chose athletes (instead of, for example, war veterans with the same symptoms) so as to remove as much of a psychological component as possible.
