An additional advantage of a focus on homogeneous dimensions of dysfunction is this: Just as some diagnoses may be best understood as a set of moderately related constructs, it is also true that certain constructs are represented in the diagnostic criteria for many different disorders. Psychological constructs cut across disorders, and disorders combine separate psychological constructs. In light of this reality, there is an opportunity for improved clarity and better guidance to clinicians by describing dysfunction in terms of its homogeneous dimensions.
