Individuals with disabilities display problem behaviors frequently. This case study presents an analysis of the extent to which one student's pattern of multiple problem behaviors and the potential efficacy of Conjoint Behavioral Consultation (CBC) as a model for linking families, schools, and special education settings to address educational concerns in order to reduce problem behaviors, increasing communication and social skills for a child with visual impairment and Autism Spectrum Disorder (ASD). The child with, multiple disabilities his parents, school teachers, and consultant were involved in conjoint consultation, a model of cross-system collaboration to address shared concerns for educational needs. In this structured educational model, parent, teacher, and special education teacher (consultant) worked collaboratively in interdisciplinary joint decision making with extensive input regarding child's individuality. The study incorporated a delayed non-concurrent multiple probe design across behaviors using qualitative explanations in mixed design. Outcome measures included parent and school teachers observations of child functioning across home, school and special education settings as a result of consultation-mediated interventions and social validity indices assessing acceptability and consumer satisfaction. Results suggested the impression that CBC is a socially valid procedure for addressing concerns of child with multiple disabilities across home, school and special education systems. Both parents and school teacher reported the consultation process to be highly acceptable although limitations with the methodology of single subject design. Research is needed to determine the contexts and conditions under which the model is more or less effective using increased number of participants.Keywords: conjoint behavioral consultation, autism spectrum disorder, problem behavior, functional assessment, delayed non-concurrent multiple baseline method
