Functional analysis of problem behavior: A systematic approach for identifying idiosyncratic variables.

When inconclusive functional analysis (FA) outcomes occur, a number of modifications have been made to enhance the putative establishing operation or consequence associated with behavioral maintenance. However, a systematic method for identifying relevant events to test during modified FAs has not been evaluated. The purpose of this study was to develop and evaluate a technology for systematically identifying events to test in a modified FA after an initial FA led to inconclusive outcomes.

Stimulus Fading and Response Elaboration in Differential Reinforcement for Alternative Behavior.

A hallmark of applied behavior analysis is the development of function-based interventions for problem behavior. A widely recommended function-based intervention is differential reinforcement of alternative behavior (DRA), in which reinforcement is contingent upon socially acceptable alternatives to problem behavior (e.g.

Evaluation of assessment methods for identifying social reinforcers.

Although researchers have evaluated assessment methods for identifying preferred tangible and edible items for children with developmental disabilities, few have evaluated assessment methods for identifying preferred topographies of attention. In the current study, indirect and direct assessments were conducted to identify 7 topographies of attention to include in subsequent preference and reinforcer assessments. Two different assessment formats were evaluated until reliable results were achieved with 1 of them.

Idiosyncratic variables that affect functional analysis outcomes: a review (2001-2010).

Although typical functional analyses often produce clear outcomes, some studies have reported ambiguous results that cannot be interpreted. Such undifferentiated outcomes may occur if test conditions do not include relevant antecedent or consequent events. Clinicians then may try to modify the functional analysis conditions to include those events.

Functional analysis screening for problem behavior maintained by automatic reinforcement.

A common finding in previous research is that problem behavior maintained by automatic reinforcement continues to occur in the alone condition of a functional analysis (FA), whereas behavior maintained by social reinforcement typically is extinguished. Thus, the alone condition may represent an efficient screening procedure when maintenance by automatic reinforcement is suspected. We conducted a series of 5-min alone (or no-interaction) probes for 30 cases of problem behavior and compared initial predictions of maintenance or extinction to outcomes obtained in subsequent FAs.

Arranging and ordering in autism spectrum disorder: characteristics, severity, and environmental correlates.

Background: There is a need for a more accurate characterisation of higher level restricted and repetitive behaviour (RRB) in autism spectrum disorder (ASD), including why it might be considered problematic and events associated with its occurrence.

Method: We selected one form of higher level RRB-arranging and ordering-that was rated as severe for a large percentage of the population sampled. We interviewed 20 students' teachers and conducted naturalistic observations for 15 of those students.

Functional analysis and treatment of arranging and ordering by individuals with an autism spectrum disorder.

Of the diagnostic features of autism, relatively little research has been devoted to restricted and repetitive behavior, particularly topographically complex forms of restricted and repetitive behavior such as rigidity in routines or compulsive-like behavior (e.g., arranging objects in patterns or rows).
