Odom et al's evaluation of comprehensive treatment models offers readers a summary of a number of essential components of 30 documented comprehensive treatment models. A number of important factors were considered and rated. These factors included (1) operationalization of the model, (2) replication of the model, and (3) type of empirical evidence supporting the model.

Odom et al.'s (2010) review also illustrated some of the challenges in evaluating comprehensive models. While efforts were made to secure as much information as possible about each model, a good deal of information was obtained via a phone interview and by reviewing information requested of and supplied by the treatment model. As the authors note, it is possible information was not properly conveyed, and as a result some models may have been rated differently depending on the information that was provided to the interviewer. It is also important to note that on-site visits of the implementation of the models were not conducted by the authors. Thus the authors did not empirically evaluate actual implementation of the model.

Although not perfect, the review is a prompt to examine data and an attempt to organize current information. The call to develop measures that can document the appropriate implementation of CTM procedures and to research the efficacy of models is valuable.
