The matrix model for clinical psychology: a contextual approach.

The four level matrix model proposed by C.R. Snyder and T.R. Elliott (this issue, PP. 1033-1054) is a bold attempt to provide a coherent philosophy and model to guide the training of clinical psychologists. Shortcomings of current training practices, such as a focus on individuals rather than community dynamics and on pathology rather than strengths, are addressed in the proposed model. Difficulties in the implementation of the model are discussed. (c) 2005 Wiley Periodicals, Inc.
