Although AAC devices were perceived as a facilitator by
parents, evidence reported by Clarke et al. [7] suggests that, at a
group level, parents’ perceived effectiveness of AAC is not a
primary facilitator of participation. In a sample of 69 children
(46 with CP) with CCP, younger age and having some intelligible
speech were associated with increased participation [7]. In
contrast, communication aid effectiveness was not associated
with level of participation [7]. This perhaps highlights the
importance of qualitative opinions in capturing the individual
needs of children.
