On the occasion of the 50th Anniversary of The Counseling Psychologist, we reflect on the many contributions that counseling psychologists have made and are poised to make in the areas of behavioral health and behavioral health care. We note that psychologists’ engagement in health promotion and prevention of behavioral, mental, and emotional disorders is consistent with counseling psychology values. We provide a concise review of theories that are widely applied in behavioral health contexts and discuss ways in which counseling psychologists may apply these theories to help ameliorate health disparities, empower communities to take control of their own health, and promote social justice. In addition, we highlight the need to create interdisciplinary partnerships to conduct culturally sensitive research on the bi-directional relationship between mental health and physical health. The article ends with wide-ranging implications and recommendations for theory development, research, training, practice, and advocacy.
