The second volume of Advances in Clinical Child Psychology continues the high standards set by the contributing authors of Volume 1. The series has been most fortunate in attracting authors who lead the field of applied child and developmental psychology in theory, research, and practice. Their chapters bring together advances from a wide variety of sub fields in essays that can legitimately be called "major statements." Often these integrative chapters prove to be more than the sum of their parts, not only bringing together information on the most current topics in the field but pointing to new directions as well. Donald Meichenbaum summarized current evidence and theory in his chapter on self-control in children. The cognitive and behavioral and convenient strategies he outlines offer the promise of effective treatment methods, but as he points out, much remains to be learned about these methods. Robert Wahler and his associates outline a new model for the study of generalization of child treatment effects. The model views the family as a system that either supports or inhibits generalization. Suggestions for planning treatments within this framework are provided, as well as an outline for extending this analysis to other levels of systems.
