Techniques are presented in three categories: (a) those that may be applied to an individual prior to, or immediately after, assaultive episodes, (b) those that promote prosocial behavior as applied on an individual basis, and (c) those that are utilized on a group basis with assaultive behavior diminishing as prosocial behaviors are promoted. Also introduced are ways to approach psychotic youths so that violent outbursts are eschewed. Treatment modifications are presented which may be helpful to children or adolescents as they progress to less restrictive settings. (Author abstract)
