Functional communication training (FCT) provides an efficient means for reducing a variety of challenging behaviors while increasing social communication. After establishing a functional communication response (FCR), interventionists may need to design a program to thin the schedule of reinforcement to provide more durable effects and maintenance…

Effective treatment of challenging behaviors in young children with autism spectrum disorder requires identifying consequences that maintain the behavior under specific environmental circumstances. Assessment strategies help to identify environmental factors setting the occasion for the behaviors to continue to occur. Many studies have used…

Functional communication training (FCT) is an evidence-based practice for individuals with autism spectrum disorder (ASD) that can be implemented by practitioners in school settings. However, few studies have explored effective and sustainable training approaches to support paraeducators in their implementation of FCT. The purpose of this study…

We conducted a meta-analysis of single-case research design (SCRD) studies on functional communication training (FCT). First, we used the What Works Clearinghouse (WWC) Standards to evaluate each study. Next, we calculated effect sizes using Tau-U. Then, we aggregated the effect sizes across the studies to produce an omnibus effect size. Results…

The purpose of this study was to evaluate the effects of workshops and coaching on paraprofessional implementation of function-based interventions. The results of indirect and direct functional behavior assessment guided the development of intervention strategies for three students with autism and intellectual disability. Following intervention,…

The nutritional status and mealtime performance among a group of children with autism spectrum disorders (ASD) were examined before and after admission to an intensive feeding day-treatment program. Treatment involved escape extinction, reinforcement, and stimulus fading procedures. Outcomes focused on dietary diversity and mealtime performance,…

The purpose of this study was to extend the research on functional communication training by examining the use of a speech-generating device (SGD) for a 7-year-old child with autism and no spoken language who demonstrated inappropriate vocalizations that served multiple functions. An analog functional analysis was used to determine the function of…

Theoretical considerations suggest that problem behavior should increase when a child's competency does not match the curricular demands of the environment (i.e., when there is poor environmental fit). In the present study, environmental fit was examined for six children with autism spectrum disorders. Results indicated that the children exhibited…

This article provides a review of current literature on the comparative validity of different functional assessment and analysis strategies. It describes functional assessment as an outcome-driven process and explains observational assessment strategies and using assessment information to plan interventions. A proposed process for teachers and…

A functional assessment interview was conducted with care providers of 100 children (ages 2-5) with autism regarding reinforcement contingencies contributing to maintenance of disruptive behavior. Gaining access to perseverative activities and escaping demands while engaged in these activities frequently contributed to disruptive behavior in the…

This discussion of positive behavior support for people with disabilities identifies four themes: (1) behavior support should reduce problem behavior and affect how a person lives; (2) functional assessment is the foundation for understanding patterns of problem behavior; (3) behavior support should be comprehensive in structure and scope; and (4)…

Discussion of family involvement in functional assessment (FA) with individuals who have autism or related disabilities first provides a rationale for family involvement, then reviews the literature and offers guidelines including: recognize, respect, and accommodate families' individuality; create a context for family centered participation; take…

This article describes the functional assessment (FA) strategies used in Project DATA (Developmentally Appropriate Treatment for Autism), a school-based model program for young children with autism. These strategies consist of five interrelated steps: (1) gathering information, (2) brainstorming, (3) making a plan, (4) implementing the plan, and…

A functional behavioral assessment for a 10-year-old boy with autism found both teacher attention and escape from task demands maintained his problem behavior. A choice-making intervention involving either completing work alone followed by a break with teacher attention versus working with teacher assistance was found to decrease problem behavior…

This article introduces this special issue on functional assessment methods and their application to children and youth with autism. It traces the 30-year history of functional assessment and briefly summarizes each of the following articles, noting the common emphasis on social validity and using the science and technology of functional…
