Kristi has conducted clinical and experimental research in depression and anxiety in Parkinson’s disease, and on cross-cultural issues in depression and its treatment. She has conducted experimental research in the malingering of head injury, placebo sleep, while in recent years focusing on sport-related topics such as sport superstition, sport concussion, stereotyping in athletes, and on how athletes may fake neuropsychological baseline tests to affect return-to-play decisions postconcussion.
Kristi’s 2018 book, The Adulteration of Children’s Sports: Waning Health and Well-being in the Age of Organized Play (Lexington Books, a division of Rowman & Littlefield), was written with the support of the Robert C. Fox Professorship at Colorado College. Discount Offer
