The Child and Adolescent Needs and Strengths

  • John S Lyons


You could describe the Child and Adolescent Needs and Strengths (CANS) as the first communimetric tool. But actually, the experiences taken from the development and implemention of the CANS led to the creation of the communication-based theory of measurement. The journey from a measure of psychiatric case mix used in a planning study in the late 1980s to a practice framework for the child-serving system resulted in collaborations with literally thousands of professionals, parents, and youth who informed the evolution of the approach. The story of the development of the CANS is really the story of the evolution of the communimetric theory of measurement.
