Multiple method validation study of facilitated communication: II. Individual differences and subgroup results

Area of Science:

• Neurodevelopmental Disorders
• Communication Sciences and Disorders

Background:

• Facilitated Communication (FC) is a method to support individuals with communication impairments.
• Autism Spectrum Disorder (ASD) and related disorders often present significant communication challenges.

Purpose of the Study:

• To investigate individual variations in the effectiveness of Facilitated Communication (FC).
• To assess the validity of FC in enhancing communication for students with autism and related disorders.

Main Methods:

• Examined 20 students with autism and related disorders over 6 weeks, with follow-up up to 7 months.
• Utilized multiple communication methods including auditory/visual input, pointing, and typing to mitigate single-method limitations.
• Collected data on FC effectiveness compared to independent communication.

Main Results:

• Findings varied across different communication methods.
• Little clear support was found for FC enhancing communication beyond independent efforts.
• Significant facilitator influence was observed, but less extensive than in prior studies.
• An 'abdication' pattern emerged in some students, showing reduced performance with FC compared to independent communication.

Conclusions:

• Individual effectiveness of FC varies significantly.
• FC may lead to more passive communication in some students with autism.
• Complex influences and potential risk factors in FC require careful consideration.
