In using the COPM as an outcome measure, the change scores from assessment to re-assessment are the most meaningful. The research evidence to date suggests that the amount of change in the COPM scores that is clinically important depends on the population, type of intervention and the environment in which intervention is done. For a full discussion of this, see the November 2021 COPM Newsletter. It is important to remember that the COPM is an individualized measure, so the meaning of the change scores may vary by individual. In using the COPM in research, it is best to set a change level, a priori.
