Functional assessment has now entered the mainstream for evaluation and to aid in the treatment of challenging behaviors, while experimental functional analysis was at the forefront of this movement, this particular methodology has proven to be impractical, and thus has limited utility in real world settings. As a result of these factors…

People with intellectual disabilities (ID) often engage in problem behaviors, such as verbal or physical aggression, property destruction, or self-injury. These behaviors become a challenge for the families and for professionals. Functional behavioral assessment (FBA) is a method used to identify variables that influence or maintain challenging…

Functional assessment has become a major feature of learning-based research. A critical element of the majority of these studies includes not only methods and procedures to identify the cause of the challenging behavior, but to establish replacement treatment methods. By far the most common intervention in the 176 studies we reviewed was…

This paper is a review of person characteristics that were present in 173 studies that were reviewed on functional assessment. The purpose was to give the reader an idea about the types of individuals for which functional assessment is appropriate and to outline persons and their characteristics which have the best research support. The majority…

One-hundred seventy-three studies that employed functional assessment were evaluated with respect to types of challenging behaviors studied and the functions identified that maintained those behaviors. For most studies, two to three behaviors were targeted. Of the 38 different challenging behaviors identified, self-injurious behavior (SIB) and…

An extensive literature on the causes of challenging behaviors has been developed, primarily in the applied behavior analysis literature. One hundred and seventy-three empirical studies were reviewed where functional assessment serves as the primary method of identifying these causes. Most of the studies were able to identify a clear function or…

Due to the relative inability of individuals with intellectual disabilities (ID) to provide an accurate and reliable self-report, assessment in this population is more difficult than with individuals in the general population. As a result, assessment procedures must be adjusted to compensate for the relative lack of information that the individual…

Great strides have been made in the development of skills and procedures to aid children with developmental disabilities to establish maximum independence and quality of life. Paramount among the treatment methods that have empirical support are treatments based on applied behavior analysis. These methods are often very labor intensive. Thus,…

The development of experimental functional analysis and more recently functional analysis checklists have become common technologies for evaluating antecedent events and the consequences of problematic behaviors. Children and developmentally disabled persons across the life span with challenging behaviors have been the primary focus of this…

Differences in subscale scores on the questions about behavioral function (QABF) were assessed for participants identified with pica, rumination, food stealing, food refusal, and mealtime behavior problems (e.g., aggression, self-injurious behavior). The QABF was administered to informants for 125 individuals identified with problematic feeding…
