This study examined the reporting of participant protections in studies involving functional analysis and self-injurious behavior and published from 1994 through 2008. Results indicated that session termination criteria were rarely reported and other specific participant safeguards were seldom described. The absence of such information in no way…

We conducted a systematic analysis of studies that involved the treatment of rumination and operant vomiting in individuals with developmental disabilities. A total of 21 studies involving a combined 32 participants were identified and analyzed in terms of (a) participant characteristics, (b) dependent variables, (c) intervention procedures, (d)…

Most often functional analyses are initiated using a standard set of test conditions, similar to those described by Iwata, Dorsey, Slifer, Bauman, and Richman [Iwata, B. A., Dorsey, M. F., Slifer, K. J., Bauman, K. E., & Richman, G. S. (1994). "Toward a functional analysis of self-injury." "Journal of Applied Behavior Analysis, 27", 197-209…

Skin-picking is a type of self-injurious behavior involving the pulling, scratching, lancing, digging, or gouging of one's own body. It is associated with social impairment, and increased medical and mental health concerns. While there are several reports showing that skin-picking is common in individuals with developmental disabilities, knowledge…

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,…

This study examined socially appropriate and destructive behavior in unconstrained natural environments using a matching law analysis (MLA) of real time observational data. The participants were two school-age children and one adult with mild to moderate cognitive disabilities. Event lagged sequential analysis (SQA) provided the obtained rates of…

In this study, the outcomes of descriptive, experimental and informant-based methods of functional assessment were compared in four individuals with developmental disabilities who showed problem behaviors. Results indicated that the descriptive and experimental assessments were concordant in only one of the four cases whilst informant-based and…

Recent studies have used pretreatment analyses, termed competing stimulus assessments, to identify items that most effectively displace the aberrant behavior of individuals with developmental disabilities. In most studies, there appeared to have been no systematic basis for selecting the sampling period (ranging from 30 s to 10 min) in which items…

The analog functional analysis involves the manipulation of pre-determined antecedent and consequent events and typically is conducted by trained experimenters. Inclusion of idiosyncratic variables in the analog functional analysis may affect responding. Inclusion of caregivers is one potential antecedent that may affect problem behavior. The…

We conducted functional analyses and identified reinforcers for problem behavior for three individuals with developmental disabilities. Based on results of the functional analysis, we evaluated the rate, probability, delay, and duration of reinforcement for problem and appropriate behavior during descriptive parent-child observations. Results…

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…
