In addition, Diehl studies how certain self-regulatory behaviors like coping strategies and emotion regulation across the adult lifespan develop and change, and how adults develop an awareness of their own age-related changes.

Diehl is a Fellow of both the Gerontological Society of America (Behavioral and Social Sciences Section) and the American Psychological Association (Division 20: Adult Development and Aging).
