Brief functional analysis and treatment of tantrums associated with transitions in preschool children

A brief functional analysis was used to examine the influence of termination of prechange activities and initiation of postchange activitieson tantrums exhibited by 2 preschool children. For 1 participant, tantrums were maintained by access to certain (pretransition) activities. For a 2nd participant, tantrums were maintained by avoidance of certain task initiations. Although advance notice of an upcoming transition was ineffective, differential reinforcement of other behavior plus extinction reduced tantrums for both participants.     

Functional analysis and treatment of the bizarre speech of dually diagnosed adults

Nine behavior-analytic studies, each reporting data for a single participant, have shown that bizarre speech can be maintained by social reinforcement. In the current study, we controlled for a possible referral bias in this literature by including nonreferred participants with dual diagnoses. Functional analyses identified attention functions for 2 participants and nonsocial functions for the others. Noncontingent reinforcement decreased the bizarre speech of both participants who displayed attention-maintained bizarre speech.     

Functional analysis and treatment of bizarre vocalizations exhibited by an adult with schizophrenia: a replication and extension

A functional analysis suggested that the bizarre vocalizations exhibited by a woman with a diagnosis of schizophrenia were maintained by attention. A treatment consisting of awareness training, competing response training, differential reinforcement of the competing response, and attention extinction was effective in reducing bizarre vocalizations. The use of self‐management based treatment components with this population and target behavior is discussed. Copyright © 2003 John Wiley & Sons, Ltd.     

Covariation between bizarre and nonbizarre speech as a function of the content of verbal attention

A functional analysis suggested that the bizarre speech of an individual with developmental disabilities was maintained by attention. The content of verbal attention was manipulated in two subsequent analyses and revealed that (a) bizarre speech was more frequent when attention was related to the participant's bizarre speech and (b) the participant's statements tended to reflect the content of the therapist's attention, whether bizarre or nonbizarre.     

Parent‐implemented brief functional analysis and treatment with coaching via telehealth

We evaluated the use of parent‐implemented brief functional analyses in the home with coaching delivered via telehealth. Parents of 7 children with autism conducted functional analyses of their child's challenging behavior. For 4 participants, the brief functional analysis provided information regarding the function of the child's challenging behavior. A full functional analysis indicated a social function for 1 participant. The brief functional analysis yielded false positive results and subsequent assessment indicated an automatic function for another participant. The final participant did not engage in sufficient rates of challenging behavior to provide information regarding the function of the child's challenging behavior. Treatment evaluations occurred with 4 participants; these evaluations provided support for the results of the functional analysis. Together with previous research, the results indicate that parent‐implemented brief functional analyses, followed by additional assessment as needed, may be an effective method for assessing and treating challenging behavior via telehealth.     

An evaluation of a brief functional analysis format within a vocational setting

We conducted and compared both brief and extended functional analyses of disruptive behaviors for 3 individuals with developmental disabilities who attended a vocational training program. Results demonstrated that the brief assessment identified the function of 2 of the 3 participants' disruptive behavior compared to the extended assessment.     

Functional analysis and treatment of verbal perseverations displayed by an adult with autism

The function of perseverative speech for an adult man who had been diagnosed with autism and mental retardation was examined. Results showed that verbal perseverations were maintained by social attention. An intervention consisting of differential reinforcement of appropriate verbal responses and extinction of perseverative verbal responding was effective in decreasing verbal perseverations.     

Use of Brief Experimental Analyses in Outpatient Clinic and Home Settings

We describe the historic and current use of brief experimental analysis procedures in outpatient clinic and home settings. We discuss some applications of the designs and suggest design modifications for improving internal validity. We describe our application of the designs to longitudinal, in-home programs for children with severe behavior disorders and demonstrate how related versions of brief experimental analysis procedures can be linked to form a more comprehensive evaluation.     

Staff-administered functional analysis and treatment of aggression by an elder with dementia

In the current study, nursing home staff were taught to administer functional analyses to determine the variables maintaining aggression by an elder with dementia. The results indicated that aggression was evoked during bathroom routines and that escape maintained aggression. Staff then reduced aggression to near-zero levels with noncontingent escape. Implications for the assessment and treatment of problem behaviors in nursing home settings are discussed.     

Brief functional analysis and supplemental feeding for postmeal rumination in children with developmental disabilities

Rumination is a serious problem demonstrated by some people with developmental disabilities, but previous research has not included a functional analysis and has rarely compared intervention methods during the assessment process. We conducted functional analyses with 2 children who displayed postmeal rumination and subsequently evaluated a supplemental feeding intervention following meals. Results showed that noncontingent food or liquid presentation effectively reduced rumination with both children.     

Clarifying an ambiguous functional analysis with matched and mismatched extinction procedures

Results of functional analysis were ambiguous in suggesting that self-injurious behavior (SIB) was maintained by escape, sensory reinforcement, or both. To help clarify these results, we compared escape extinction, sensory extinction, and the combined treatments. Sensory extinction proved to be a necessary and sufficient treatment, whereas escape extinction failed to decrease SIB. These analyses helped to clarify the function of SIB and to identify an effective and efficient treatment.     

Using Brief Experimental Analysis to Select Oral Reading Interventions: An Investigation of Treatment Utility

This study examined the treatment utility of brief experimental analysis for selecting skill-based oral reading interventions that targeted acquisition and fluency. Two second and one third grade student served as participants. The potentially most and least effective instructional packages identified from the brief experimental analysis for each student were alternated during an extended analysis phase. The instructional components that were compared were based on an ease of implementation hierarchy, with the brief experimental analysis used to select the hypothesized most effective instructional package for oral reading. Visual analysis of extended analysis data revealed that the hypothesized most effective combination of instructional components identified from the brief analysis produced greater initial gains in reading for two children (i.e., over 29 and 21 intervention days) and greater gains in reading throughout the extended analysis phase for the third child. Thus, the investigation provided preliminary evidence for the treatment utility of using brief experimental analysis to select effective and efficient oral reading instructional interventions. Implications, limitations, and future research topics are discussed.     

An evaluation of response cost in the treatment of inappropriate vocalizations maintained by automatic reinforcement

In the current study, we examined the utility of a procedure consisting of noncontingent reinforcement with and without response cost in the treatment of inappropriate vocalizations maintained by automatic reinforcement. Results are discussed in terms of examining the variables that contribute to the effectiveness of response cost as treatment for problem behavior maintained by automatic reinforcement.     

The impact of functional analysis methodology on treatment choice for self-injurious and aggressive behavior.

Self-injurious behavior (SIB) and aggression have been the concern of researchers because of the serious impact these behaviors have on individuals' lives. Despite the plethora of research on the treatment of SIB and aggressive behavior, the reported findings have been inconsistent regarding the effectiveness of reinforcement-based versus punishment-based procedures. We conducted a literature review to determine whether a trend could be detected in researchers' selection of reinforcement-based procedures versus punishment-based procedures, particularly since the introduction of functional analysis to behavioral assessment. The data are consistent with predictions made in the past regarding the potential impact of functional analysis methodology. Specifically, the findings indicate that, once maintaining variables for problem behavior are identified, experimenters tend to choose reinforcement-based procedures rather than punishment-based procedures as treatment for both SIB and aggressive behavior. Results indicated an increased interest in studies on the treatment of SIB and aggressive behavior, particularly since 1988.     

Noncontingent reinforcement as treatment for food refusal and associated self-injury

We examined the use of noncontingent reinforcement to decrease self-injury and increase bite acceptance in a child who exhibited food refusal. First, a brief functional analysis suggested that self-injury was maintained by escape from food presentation. Next, we evaluated an intervention that involved noncontingent access to a video during feeding sessions. Results of the intervention showed a decrease in self-injury and an increase in bite acceptance.     

Functional analysis and treatment of adult problem behavior: A review

Functional analysis (FA) methodology has been deemed the best practice in the field of applied behavior analysis. The data collected in an FA allows behavior analysts to develop the most effective and ethical behavior interventions. With the diagnosis for individuals with autism on the rise along with the forecast of adults who will need support, it may be time to take stock of the available literature. The purpose of this review was to evaluate the behavior analytic research over the last 25 years (1997–2022) on FA and treatment for adults who engage in severe problem behavior. Utilizing specific inclusion and exclusion criteria resulted in the identification of 28 articles. These articles were examined across participant characteristics, target behavior, FA type, FA settings, interventions, generalization, and maintenance. Implications on adult FA and treatment are discussed along with recommendations for practitioners who desire to support this population.     

Brief functional analysis and treatment of eye poking

A brief functional analysis suggested that eye poking exhibited by a 5‐year‐old boy diagnosed with cortical visual impairment was maintained by automatic reinforcement. Levels of eye poking in additional conditions suggested that the behavior might be maintained by visual stimulation. Response blocking through the use of safety goggles effectively reduced eye poking in the analog setting. Data from the natural environment suggest that, during intervention, eye poking was confined to times when response blocking was not in effect. Copyright © 2002 John Wiley & Sons, Ltd.     

The significance and future of functional analysis methodologies

Iwata, Dorsey, Slifer, Bauman, and Richman (1982) presented the first comprehensive and standardized methodology for identifying operant functions of aberrant behavior. This essay discusses the significance functional analysis has had for applied behavior analysis. The methodology has lessened the field's reliance on default technologies and promoted analysis of environment-behavior interactions maintaining target responses as the basis for selecting treatments. It has also contributed to the integration of basic and applied research. Future directions for this research are suggested.     

Analogue functional analysis of movements associated with tardive dyskinesia

We studied whether movements associated with tardive dyskinesia (TD) served operant functions in 2 men with developmental disabilities. We found that TD-related movements occurred more frequently in the alone and attention conditions and less frequently in control and demand conditions. Our findings suggest that TD-related movements may not be maintained by social reinforcers and that decreases in TD movements are possibly a result of engagement in activities that are incompatible with TD movements.     

Efficiency in functional analysis of problem behavior: A quantitative and qualitative review

Originating in the mid-1960s, functional analysis (FA) has become the gold standard method for understanding the environmental variables that come to shape and maintain problematic behaviors such as aggression, self-injury, and property destruction. Over the decades, a number of studies have refined FA methods, attempting to improve the overall efficiency of the analysis through experimental design and procedural modifications. In the present review, we used ongoing visual-inspection criteria and basic probability theory to compare and analyze levels of efficiency across FA types. The multielement design and synthesized contingency analyses were about equally efficient with respect to the mean number of sessions conducted per function tested, and the trial-based and synthesized contingency analyses were the 2 most efficient with respect to the mean duration per function tested. We discuss the implications of these findings in the broader context of efficiency and provide recommendations for maximizing efficiency during an FA. We also discuss other qualitative procedural details that may influence the overall efficiency of an FA.
