The decision to change the language is an example of the evolving nature of culture and the interaction of language and the sociopolitical context. The terms that were chosen to describe each of the cultural groups represented in the book were selected by the chapter authors in keeping with accepted terminology at the time of the writing. The spelling and capitalization of terms were also determined by contributing authors. Throughout this edition, non-English words are set in italics. This inconsistency of terms was preserved because it exemplifies the differing cultural perspectives and points of view.
Language is a powerful tool in any interaction and the way that it is used is full of lessons.
The primary lessons related to terminology in this edition are that terms change and the ones chosen should describe groups of individuals based on their preferences. We have chosen the word interventionist to refer to a person who provides educational, health care, or social services to children and families. This does not imply that these individuals act on, change, or contravene the family's preferences. Rather, it is intended to describe the role of the many service providers working within the sphere of their disciplinary expertise who consult with, provide information to, support, or provide other direct services to children and families.
