Perceptions of psychosocial adjustment to aphasia: applications of the Code--Müller Protocols.

We review research that has examined people's perceptions of likely psychosocial adjustment of aphasia. People's perceptions differ depending on whether they have aphasia themselves, are related closely to a person with aphasia, or work with the aphasic person in a professional capacity. In addition, people differ in what they perceive are the most important or relevant factors for psychosocial adjustment, and this too depends on whether they have aphasia themselves, are a relative or "significant other" in the aphasic person's life, or are a health professional working with the person with aphasia. Furthermore, there are marked differences in the way individuals predict likely psychosocial adjustment, and these perceptions can change over time. Most of this research has used the Code-Müller Protocols (CMP) to examine these perceptions. This article describes the development and application of the CMP in aphasia.
