Selective Mutism, Adjustment Disorders, and Gender Identity Disorder
This chapter originally included some of the categories grouped together in DSM-IV under the heading of "Other Disorders of Infancy, Childhood, and Adolescence" (see Table 16.1). Some of these "other" disorders seemed suited for placement with other major categories in this book for convenience of discussion or to point out diagnostic differences. Reactive Attachment Disorder of Infancy or Childhood found a place in Chapter 7 ("Developmental Abnormalities in the First Years of Life"), Stereotypy/Habit Disor der is discussed in Chapter 11 ("Disorders Manifesting a Physical Nature"), and Separation Anxiety Disorder is in Chapter 14 with the Anxiety Disorders. Identity Disorder, included in DSM-III-R under "Other Disorders of Infancy, Childhood, or Adolescence," has been dropped from DSM-IV; however, a similar category, Iden tity Problem, was added here under "Other Conditions That May Be a Focus of Clinical Attention" (see Chapter 18). In DSM-IV, a residual category-Disorder of Infancy, Childhood, and Adoles cence NOS (313.9)— was added to the "other" section for coding those disorders with onset in infancy, childhood, or adolescence that do not meet specific criteria for any classification.
