This article reviews the concept that professional psychology is synonymous with mental health. The acceptance of this concept results in limiting the potential impact that psychology has for both individuals and society. Historical antecedents of both psychology and professional psychology are considered as laying a foundation for a necessary paradigm shift from primarily mental health to health. Clinical neuropsychology, health psychology, and prescriptive authority are considered as three examples that may assist in guiding professional psychology toward inclusiveness into a broader health care arena. Limitations of the proposed paradigm and directions for its future are considered. (PsycINFO Database Record (c) 2011 APA, all rights reserved).
