Introducing the therapy outcome measure for AAC services in the context of a review of other measures.
OBJECTIVE
This article discusses the importance of outcome measures in improving Augmentative and Alternative Communication (AAC) services, reviews existing methods and introduces a new approach.


METHODS
Three methods were used in this study. 1. A literature review identifying outcome measures used in AAC research. 2. A questionnaire to AAC services in the UK which aimed to identify the objectives of their services and the outcome measures commonly used. 3. A working group of AAC experts provided additional information and interpretation. Central properties and conceptual framework were considered.


RESULTS
The literature review and questionnaire identified 23 outcome measures none of which cover the conceptual frameworks associated with all of the overall objectives of AAC provision. The review has informed the further development of a particular outcome measure the AAC Therapy Outcome Measure (AAC TOM) ensuring that basic principles of the International Classification of Functioning (ICF-WHO) are retained and the measure can be used in benchmarking.


CONCLUSIONS
An outcome measure needs to reflect change associated with service delivery. AAC services endeavour to impact on all of the domains of the ICF. A new measure is required in order to reflect the nature of these services. This article introduces an outcome measure which is in the process of being trialled by some services in the UK.
