A functional behavior assessment is an evidence-based process that identifies the function of challenging behaviors in order for educators to develop behavior intervention plans for students with disabilities. All behaviors are under stimulus control and research indicates that behaviors typically serve four functions: tangible, escape, attention,…

Over the past several decades, we have developed quality behavioral assessments and interventions for challenging behaviors among individuals with a variety of severe developmental and cognitive disorders. These assessments and interventions have been used to educate family members on how to understand and intervene with these behaviors at home…

Functional Behavior Assessment (FBA) and behavior interventions have been effective in the management of challenging behavior among children with developmental disabilities including autism spectrum disorders. Research suggests the need for valid measurement instruments for verifying, calibrating and scoring competence in FBA and behavior…

In the past several years, there has been an important movement to reduce the utilization of restraint for individuals with developmental disabilities. Legislatures, local and national, are taking on the task of shaping the way that our culture supports people who, up until now, have been often treated in a punitive manner rather than truly…

The number of children identified as having intellectual or developmental disability is rising worldwide and their education has been found wanting. It has been said that "they simply need better teaching." At the same time, there is an increasing evidence base that pedagogy that is based on the discipline of behaviour analysis offers…

The prevalence of Autism Spectrum Disorders (ASD)--a group of developmental disabilities that cause severe problems with socialization, behavior, and communication--continues to grow. In 2008, the year that "Odyssey" focused on autism, the estimated prevalence of ASD for hearing children was 1 in 150 (CDC, 2007), while today estimates suggest…

We describe a procedure for differentiating among potential precursor responses for use in a functional analysis. Conditional probability analysis of descriptive assessment data identified three potential precursors. Results from the indirect assessment corresponded with those obtained from the descriptive assessment. The top-ranked response…

Challenging behavior can create significant obstacles to academic and social progress for individuals in a school setting, particularly those with developmental disabilities. Functional assessments such as rating scales, ABC analyses, and functional analyses, are evidenced to be the most effective methods for identifying the maintaining variables…

Sensitivity theory attempts to account for the variability often observed in challenging behavior by recourse to the "aberrant motivation" of people with intellectual and developmental disabilities. In this article, we suggest that a functional analysis based on environmental (challenging environments) and biological (challenging needs) motivating…

Ethical guidelines for behavior analysts state that functional assessment should be used before implementing treatment plans. In this paper, we discuss the ethical implications of this position using self-injurious behavior in people with developmental disabilities as a focus. Evidence is reviewed that suggests that treatment based on results of a…

Several methods for evaluating the influence of antecedents on challenging behaviour have been described in the literature, however the portability of these methods within the classroom has been questionable. The purpose of this paper will be to provide a practical understanding of evidence-based practices used in the assessment and management of…

The Individuals With Disabilities Education Act (IDEA) Amendments of 1997 mandate the use of functional behavioral assessment (FBA) and positive behavioral supports and interventions for students with disabilities. Although much progress has been made in our understanding of functional analysis over the past 15 years, the extent to which these…

The Questions About Behavioral Function (QABF), a 25-item rating scale, was developed to identify the function(s) of maladaptive behavior in individuals with developmental disabilities. The authors adapted it for use with individuals with serious mental illness who engage in maladaptive behavior and assessed the psychometric characteristics of the…

As a result of inherent cognitive and language difficulties, individuals with mental retardation/developmental disabilities often are considered difficult to assess appropriately. When cognitive and language difficulties occur in conjunction with behavioral issues, this difficulty is compounded. The IDEA requirement to include a form of…

In the last few decades, the field of dual diagnosis as applied to those with intellectual disabilities has boasted a monumental surge in assessment devices and treatment approaches. These relatively recent advances include those in the development of behavior modification principles and procedures that have had a dramatic impact on services for…
