Importance of Research-based Interventions • Facilitated Communication • Originated in Australia and was initially used with individuals with CP • Fundamental premise is that some people have “undisclosed literacy” and simply experience difficulty with expression not a cognitive limitation (Jacobson, Foxx, Mulick, 2005b; Kavale and Mostert, 2004) • Research has repeatedly failed to support FC • Jacobson et al. (2005b) Reviewed 9 studies since 1992 that supported FC but found major methodological errors • Virtually every appropriately designed study failed to support communicator authorship Hyatt, Filler, & Krasch; TASH 2009 16
Importance of Research-based Interventions • Facilitated Communication (continued) • Mostert (2001) reviewed 29 studies • 19 provided one or more control procedures refuted FC • 6 provided one or more control procedures supported FC • 4 with no controls supported FC • Review confirms prior research with high quality research failing to support FC & those supporting FC were so methodologically poor that results can’t be accepted • Experimental rigor required if there is any hope of demonstrating efficacy of FC • Noted findings consistent with prior reviews (e.g., Cummins & Prior, 1992; Green, 1992, 1994; Hudson, 1995) Hyatt, Filler, & Krasch; TASH 2009 17
