The Rancho has been widely used but the categorical nature of the scale is its major drawback. Specifically, the scale has been criticized because it does not reflect subtle changes in recovery, does not differentiate changes along one dimension and not another, and it can be difficult to classify an individual when the patient manifests behavioral characteristics appropriate to more than one category of the scale.
