Mental health and mental health problems among users of AAC: a scoping review

Functional communication is crucial for mental health and for coping with mental health problems. People with disabilities are at increased risk of mental health problems, and people who use augmentative and alternative communication (AAC) are reported to be at greater risk of depression and anxiety than people without impairments. This scoping review summarizes existing knowledge about the mental health and mental health problems of people who use AAC. The review includes nine publications, published between 2001 and 2022. These mainly report on adults and elderly people who use AAC. Four of the nine publications included people who use AAC due to acquired impairments. None of the studies reported the prevalence of mental health problems and only a few addressed factors of positive mental health. The results indicate a shortage of theoretical accounts for most of the publications included, and the publications are not built on each other. The scarcity of knowledge is discussed in relation to the idea that the need for communicative support is a need based on communicative functioning rather than any diagnostic category and thus not visible in much of the health literature based on diagnostic categories. Several implications for practice and research are suggested.
