About Dr. Dahlen
I am an Associate Professor in the Counseling Psychology Program of the Department of Psychology at the University of Southern Mississippi. My research interests focus on dysfunctional anger; overt and relational aggression; and clinical traffic psychology (i.e., the contribution of driver personality to aggressive driving and other accident-related behaviors). At the graduate level, I teach courses in group therapy and the assessment and diagnosis of mental disorders. At the undergraduate level, I teach abnormal psychology and forensic psychology. I am a licensed psychologist and a certified anger management specialist. I serve as Director of the Community Counseling and Assessment Clinic, the in-house training clinic of the Counseling Psychology Program.
I received my doctorate at Colorado State University under the direction of Jerry L. Deffenbacher, Ph.D. I was fascinated by his work on cognitive-behavioral treatments for angry individuals, and I worked with him in evaluating interventions for generally angry college students and angry drivers. My dissertation, published in the Journal of Cognitive Psychotherapy, was a treatment study involving the application of Beck's Cognitive Therapy to generally angry students.
I carried my interest in anger to the University of Southern Mississippi. I soon decided to expand my previous work on driving anger to the subject of aggressive driving, examining a variety of other personality traits which had not received sufficient attention in the traffic psychology literature (e.g., boredom proneness, sensation seeking, impulsiveness, etc.). At the same time, I set up an anger management program through the Community Counseling and Assessment Clinic, trained therapists, and began collecting treatment data. Based on these clinical data, I realized that the treatment protocols I had previously used with college students needed to be modified for community adults. My efforts along these lines have focused on developing brief strategies for enhancing client readiness for change.
I am a Distinguished Diplomate of the National Anger Management Association and a Certified Anger Management Specialist-V, which permits me to train and supervise students interested in pursuing certification.
