An Investigation of Aided Language Stimulation: Does it Increase AAC Use with Adults with Developmental Disabilities and Complex Communication Needs? (short summary)


The authors investigated whether the use of Aided Language Stimulation (ALS) i.e. communication partners modelling the use of AAC using a system the same or very similar to that used by the AAC user, could be beneficial in teaching adults with developmental difficulties and complex communication needs to use AAC. They aimed to consider the effect of ALS on functional use of AAC.

A group of adult AAC users were given a number of intervention sessions in which the researchers modelled the use of AAC following set scripts in structured situations and supported the people who used AAC to use their systems to participate. Speaking peers of the participants were also involved as role models.

Over the intervention period all of the people who used AAC were found to have increased both the number of communicative turns they took and their use of AAC. However this was not always maintained after the intervention period.

Overall the authors conclude that ALS can 'help adults with developmental disabilities and complex communication needs to learn, maintain and enhance their ability to communicate functionally in their natural settings, and, therefore, to participate more fully in life.'
