The Communicative Performance Measure (CPM) (1)

We report on the development of the Communicative Performance Measure (CPM) as a method of assessing activity and participation in persons with speech disorders such as dysarthria(Ozawa, 2012; Ozawa, et al., 2019).
CPM is a rating system in which a person with speech disorder and his or her main communication partner each rate the comprehensibility of disordered speech and degree of satisfaction with comprehensibility for the person with speech disorder.
Our experience of applying CPM suggests that it is useful as a means of collaboratively exploring communication problems and promoting intervention approaches after obtaining ratings from the clients themselves.

Introduction

In the clinical management of speech disorders such as dysarthria, intelligibility is considered the primary evaluation measure.  However, intelligibility focuses on speech (impairment) and is not a sufficient indicator considering the ultimate goal of support (speech therapy) is to improve communication (activity limitation, participation restriction). However, attempts have been made to estimate the communicative performance of persons with speech and language disorders through questionnaires and evaluation forms, but these do not necessarily correspond to the individual characteristics of clients, such as environmental and personal factors.
We report on the Communicative Performance Measure (CPM), which was developed based on the concept of comprehensibility by Yorkston et al.(1996).
CPM is a simple method in which a person with speech disorder and his or her main communication partner are asked how they perceive daily communication, and the results are quantified. Our experience using this method suggests that it can be employed to share the status and thoughts of daily communication, which only those concerned can know, and to provide opportunities for independent thought and action regarding problems.
