As the study of the family has expanded, the need for an up-to-date volume that brings together and defines major salient words, phrases and concepts has similarly grown. The updated edition of this unique resource provides an expanded yet compact and handy reference for all practitioners, researchers and students in the fields of family psychology and psychotherapy.

Each entry includes a definition of the term, an example of its use, the origin of the term, an early source using the term and, if pertinent, a recent source. `Borrowed' terms from other fields such as family law, sex therapy, clinical child psychology and group psychology are also included.
