The question “Are you any good?” only makes sense in the context of “Compared to what?” Benchmarking provides therapists with a way to answer this question and to evaluate if their performance is improving over time.
The term Benchmark Score is used in ACORN clinical reports to convey the idea that the residualized gain score provides information on the extent to which the patient's change score differed from the average (benchmark) change score as calculated using the General Linear Model for case mix adjustment.
A positive Benchmark Score indicates that the patient has reported more improvement than expected when compared to comparable patients in the database.
