The field of professional psychology has been tremendously successful, although it has also been characterized by many competing preparadigmatic theoretical orientations, which have led to a great deal of contention as well as conflicting views regarding psychological development, functioning, and behavior change. There is now widespread agreement regarding scientific explanations of many psychological processes, however, and, consequently, it is time to update the basic conceptual frameworks used for professional psychology education and practice. Replacing the traditional reliance on an array of theoretical orientations with a science-based biopsychosocial framework would resolve many of the contradictions and conflicts that characterized the preparadigmatic era and would also provide a common perspective for unifying psychologists around a shared approach to practice, research, and training.
