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…

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…

Autism has become one of the most heavily researched topics in the field of mental health and education. While genetics has been the most studied of all topics, applied behavior analysis (ABA) has also received a great deal of attention, and has arguably yielded the most promising results of any research area to date. The current paper provides a…

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…

The assessment of maintaining variables with the goal of developing prosocial intervention plans has become a driving force in the intellectual disabilities (ID) literature. One particularly crucial variable is whether the behavior is low or high rate and whether the challenging behavior is best characterized by self-injury or aggression. Because…

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…

Background: The "Questions About Behavioral Function" (QABF) correctly identifies maintaining variables of challenging behaviour. However, for adults who have a long history of challenging behaviours, identifying one clear function of the maladaptive behaviour is difficult. Additionally, the person may develop multiple functions of their…

Since many problem behaviors of individuals with mental retardation are maintained by multiple functions, this project developed the Functional Assessment for multiple CausaliTy (FACT), an informant-based, forced-choice measure designed to identify the most prominent function associated with the occurrence of problem behaviors. This paper…

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…
