For those of us wanting to use DIR with people past "early intervention" age, read the fascinating and inspiring case study of DIR used with Autistic Adolescents published in the ICDL Journal of Developmental and Learning Disorders. An excerpt: Indeed, although it is frequently associated with treating children,
DIR interventions can be initiated at any age and in a variety of circumstances. Individuals are capable of making significant developmental progress throughout adolescence and adulthood. Appropriate and effective interventions can be initiated at any age. Too often, caregivers with adolescents and adults assume they have reached a point where they can no longer make major gains and teach superficial skills and routines, instead of attempting to foster development (Greenspan & Mann, 2000.) http://www.icdl.com/bookstore/journal/index.shtml and you'll find the article in the 2002 issue, on pages 49-69. While you're at it, browse through the publications! There is a wealth of valuable information, and it is free.
