This chapter describes the identity of couple, marriage, and family practitioners; traces the history of couple, marriage, and family professional associations; discusses relevant accreditation organizations and pertinent specializations; explores the nuances of professional practice, including scholarly trends, telebehavioral health and therapeutic technology, understanding wellness, and interventions used during times of crisis, trauma, and disaster; and introduces the concepts of context, diversity, multiculturalism, and intersectionality. This chapter serves as a guide for the remainder of the book. Specifically, every topic introduced within this chapter will set the stage for additional theoretical, skill-based, and contemporary issues covered within the remaining chapters of this textbook.
