Abstract
An adult male client who complained of an articulation disorder of the /k/ sound was reported. The author found that the client did not show the articulation disorder; however, he felt a lot of difficulties in his life. The author supposed that the client might have psychoneurotic problems and recommended him to meet a psychiatrist or clinical psychologist. He was diagnosed as a borderline personality disorder patient by a psychiatrist. Recently, a national license system of speech therapists has been established in Japan, and it will become more generalized especially in the general population. We may encounter more frequently this type of psychoneurotic patients complaining of speech problems in the future. Therefore, it will be a great help for us to have a view-point of clinical psychology when we consider how to deal with such clients.
