The final part of my keynote talk at the AAC Conference in Helsinki last month focused on what we mean by communication effectiveness.
It is important to be able to determine the effectiveness / success of an interaction between two people, whether they are politicians, parent and child, husband and wife….. people using AAC systems or people using their own speech.
When I carried out a literature search of peer reviewed journals for my PhD in 2009 I could find no clear definition of communication effectiveness. Some people thought that effectiveness was synonymous with ‘word intelligibility’ or ‘correct syntax’. Others defined effectiveness in terms of the number of words produced on an AAC device. One publication even suggested that effectiveness was demonstrated by someone taking responsibility for charging their AAC device!
The main focus of all the papers I found, which mentioned communication effectiveness, was on needs and wants and only 3 papers cited social closeness as important (click here to read previous blog).
However, some publications did give useful pointers. Light (1988) emphasised that effective communication depends on 2 way interaction and that the partner is a major factor in the success or failure of communicative interactions. Lund (2006) described adequacy, relevance, promptness and communication sharing as key indicators. Ho et al (2005) highlighted satisfaction – partners’ feeling of how well they communicated during the conversation. Locke (1998) stressed that determining the success of any communication is a subjective undertaking as ‘Communication is not a mathematical formula of phonemes, morphemes and syntax, but rather includes casual conversation such as gossip’.
The Talking Mats team has tried to capture what we believe are the essential factors in determining communication effectiveness. We have produced a simple tool – the Effectiveness Framework of Functional Communication (EFFC) which can be used to chart key factors in an interaction on a 5 point scale and give an overall indication of whether the conversation is effective or not.
We have used the EFFC in several of our research projects and show participants how to use it during our training workshops. In Finland I tried it out with the audience of 200 AAC professionals using 3 video examples of different AAC conversations. The resulting scores were amazingly in agreement suggesting that this is a reliable tool.
