As the methods for the functional analysis of problem behavior have continued to develop, there has been a greater focus on the specificity of controlling variables, both antecedents and consequences. Accelerating research interest in the role of antecedents reveals that a large array of stimulus variables can influence the rate of problem behavior. Indeed, the variety of these stimuli is so great that it is sometimes possible to overlook specific stimulus variables during initial assessment…

Further analysis of idiosyncratic antecedent influences during the assessment and treatment of problem behavior.
Functional analyses indicated that idiosyncratic antecedent stimuli set the occasion for occurrences of problem behavior (hand biting or hand flapping) and that problem behavior persisted in the absence of social contingencies.
Identifying the Effects of Idiosyncratic Variables on Functional Analysis Outcomes: A Case Study.
Abstract Functional analysis is being implemented increasingly in naturalistic applied settings and with more diverse, high-functioning populations. The number of idiosyncratic variables potentially
The Use of Additional Analyses to Clarify the Functions of Problem Behavior
Functional analysis methodology has proven useful for identifying environmenta l co ingencies that influence problem behavior. Extensions of traditional functional analysis methodology have shown
The Influence of Idiosyncratic Antecedent Variables on Problem Behavior Displayed by a Person with PDD
This study describes an assessment of the influence of idiosyncratic antecedent variables on the problem behavior of a 9-year-old boy with pervasive developmental disorder and attention deficit
Functional analysis of problem behavior: a review.
The literature was reviewed in an attempt to identify best practices and directions for future research on pretreatment functional analyses.
Using Additional Analyses to Clarify the Functions of Problem Behavior: An Analysis of Two Cases
Functional analyses (FA) have proven useful for identifying contingencies that influence problem behavior. Research has shown that some problem behavior may only occur in specific contexts or be
Escape behavior during academic tasks: a preliminary analysis of idiosyncratic establishing operations.
The data suggest that the four-step procedure was effective in identifying methods of instruction that decreased the likelihood of destructive behavior without disrupting the maintaining contingencies for destructive behavior.
When Reinforcers for Problem Behavior Are Not Readily Apparent
The goal of functional assessment is to identify events associated with problem behavior. Once these variables are identified, support plans can be based on the events associated with behavioral
Strategies for Clarifying Ambiguous Functional Analysis Outcomes
The development and refinement of functional assessment technology in the last 20 to 25 years has greatly advanced the behavioral treatment of problem behaviors (e.g., E. G. Carr & Durand, 1985; E.

The functional control of problem behavior is generally conceptualized as involving attention, escape, sensory reinforcement, and tangible factors. Our analytic tools have now reached a level of
Descriptive and experimental analyses of variables maintaining self-injurious behavior.
Results indicated that the descriptive analysis was useful in identifying the extent to which SIB was related to social versus nonsocial contingencies, but was limited in its ability to distinguish between positive and negative reinforcement.
Reduction of Severe Problem Behavior in Community Employment Using an Hypothesis-Driven Multicomponent Intervention Approach
Individuals with severe problem behavior typically are excluded from integration efforts involving community employment. This study examined one strategy for reducing severe problem behavior in an
Basing the treatment of stereotypic and self-injurious behaviors on hypotheses of their causes.
Results showed that a successful treatment program can be developed on an hypothesis of why the behavior occurred during baseline, supporting the argument that treatment programs should be based on a functional analysis of the behavior in its environmental context.
Use of descriptive and experimental analyses to identify the functional properties of aberrant behavior in school settings.
Analysis of descriptive and experimental analyses of aberrant behavior in school settings with 2 children with autism and a comparison of the assessment procedures showed that each procedure identified negative reinforcement as a maintaining variable for Aberrant behavior.

This series of studies illustrates a method for identifying some establishing operations for escape by systematically altering certain dimensions of the demand context while maintaining an escape contingency for SIB.
Toward a functional analysis of self-injury.
Reduction of severe behavior problems in the community using a multicomponent treatment approach.
The multicomponent intervention included choice making, embedding, functional communication training, building tolerance for delay of reinforcement, and presenting discriminative stimuli for nonproblem behavior in supermarkets without problem behavior.
The effects of meal schedule and quantity on problematic behavior.
The results replicate and extend previous findings demonstrating that meal schedule or food quantity can affect problematic behavior and brief functional analyses of aberrant behavior provided useful information for interpreting distinct patterns of behavior displayed by each child.
Stimulus control of self-destructive behavior in a psychotic child
Results were interpreted as suggesting that self-destruction, under certain circumstances, may be conceptualized as an escape response which is negatively reinforced by the termination of a demand situation and certain modifications of the social environment may provide discriminative stimuli for behaviors other than self-Destruction, thereby decreasing this behavior.
