Functional analysis (FA) methodology is the most precise method for identifying variables that maintain problem behavior. Occasionally, however, results of an FA may be influenced by idiosyncratic sensitivity to aspects of the assessment conditions. For example, data from several studies suggest that inclusion of a tangible condition during an FA may be prone to a false-positive outcome, although the extent to which tangible reinforcement routinely produces such outcomes is unknown. We examined susceptibility to tangible reinforcement by determining whether a new response was acquired more readily when exposed to a tangible contingency relative to others commonly used in an FA (Study 1), and whether problem behavior known not to have a social function nevertheless emerged when exposed to tangible reinforcement (Study 2). Results indicated that inclusion of items in the tangible condition should be done with care and that selection should be based on those items typically found in the individual's environment.  相似文献

Researchers typically modify individual functional analysis (FA) conditions after results are inconclusive (Hanley, Iwata, & McCord, 2003). Hanley, Jin, Vanselow, and Hanratty (2014) introduced a marked departure from this practice, using an interview‐informed synthesized contingency analysis (IISCA). In the test condition, they delivered multiple contingencies simultaneously (e.g., attention and escape) after each occurrence of problem behavior; in the control condition, they delivered those same reinforcers noncontingently and continuously. In the current investigation, we compared the results of the IISCA with a more traditional FA in which we evaluated each putative reinforcer individually. Four of 5 participants displayed destructive behavior that was sensitive to the individual contingencies evaluated in the traditional FA. By contrast, none of the participants showed a response pattern consistent with the assumption of the IISCA. We discuss the implications of these findings on the development of accurate and efficient functional analyses.  相似文献

Functional analysis can often be a lengthy process requiring time and resources not readily available to practitioners working with children who exhibit severe problem behavior. The interview‐informed synthesized contingency analysis (IISCA) was recently developed as an alternative functional analysis format that improved analytic efficiency by requiring only 25 min to conduct. Furthermore, a within‐session analysis of the first test session of the entire IISCA could reduce the process to as little as a single 5‐min session. We extended this previous research by conducting what was termed the single‐session IISCA with three boys who exhibited severe problem behavior. A function‐based treatment package, including reinforcement thinning, informed by the results of the single‐session IISCA nearly eliminated problem behavior for all three participants. We suggest that the single‐session IISCA could be a viable alternative to other functional analysis formats when time is limited.  相似文献

Problem behavior is common in early childhood special education classrooms. Functional communication training (FCT; Carr & Durand, 1985 ) may reduce problem behavior but requires identification of its function. The trial‐based functional analysis (FA) is a method that can be used to identify problem behavior function in schools. We conducted trial‐based FAs and FCT with 3 children in an early childhood special education setting. All trial‐based FAs resulted in identification of behavioral functions, and subsequent FCT led to reductions in problem behavior and increases in communication.  相似文献

Hanley, Jin, Vanselow, and Hanratty (2014) described a functional analysis (FA) format that relied on a synthesis of multiple contingencies described by caregivers during open‐ended interviews. These interview‐informed synthesized contingency analyses (IISCA) provided effective baselines from which to develop socially validated treatments, but the synthesis precluded a precise understanding of individual contingencies influencing problem behavior. We conducted IISCAs and standard FAs (Iwata, Dorsey, Slifer, Bauman, & Richman, 1982/1994) for nine children with autism to evaluate the likelihood of differentiation given a number of synthesized versus isolated variables. The IISCA was differentiated for all. The standard FA was differentiated for four; this number increased to six when we included precursors in the standard FA. We then compared treatments based on sets of differentiated analyses for four children. Treatment based on the IISCA was effective for all four; treatments based on the standard FA were effective for two. The role of synthesis in analysis is discussed.  相似文献

Although a demand analysis is helpful for identifying potential establishing operations for the functional analysis (FA) demand condition, it may not always be practical due to time constraints. A potential alternative is the Negative Reinforcement Rating Scale (NRRS), an indirect assessment tool that may serve as a time efficient alternative to a demand analysis. The experimenter assessed the reliability and validity of the NRRS for 5 individuals with autism spectrum disorder who exhibited problem behavior. Multiple types of interrater reliability were assessed across 2 informants, and NRRS outcomes were compared to a subsequent demand analysis and FA to assess its validity. Reliability was high (M = 84%) for NRRS numerical ratings of categories but low (M = 32.9%) for specific examples provided. NRRS-identified highly aversive tasks yielded better correspondence with demand analysis outcomes than did NRRS-identified less aversive tasks.  相似文献

We compared the functions of problem behavior identified by (a) a functional analysis (FA), (b) an interview-informed synthesized contingency analysis (IISCA) that was informed by the results of an open-ended interview and a structured observation, and (c) a standardized-synthesized contingency analysis (SSCA) in which we synthesized three common functions of problem behavior across 12 individuals in a controlled consecutive case series. We then compared outcomes across assessments. The FA was sufficient in identifying the variables maintaining problem behavior for 11 of the 12 participants, replicating the findings of Fisher, Greer, Romani, Zangrillo, and Owen (2016). Error type (i.e., false positives, false negatives) and error prevalence were similar across functions identified by the IISCA and the SSCA, calling into question the utility of the open-ended interview and the structured observation that informed the IISCA.  相似文献

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.  相似文献

Recent research suggests that combining putative reinforcers for problem behavior into a single, synthesized contingency may increase efficiency in identifying behavioral function relative to traditional functional analysis (FA). Other research suggests potential shortcomings of synthesized contingency analysis (SCA), such as the potential for false-positive outcomes. In prior comparisons of traditional FAs and SCAs, investigators could not ascertain with certainty the true function(s) of the participants' problem behavior for use as the criterion variable. We conducted a translational study to circumvent this limitation by training a specific function for a surrogate destructive behavior prior to conducting a traditional FA and SCA. The traditional FA correctly identified the previously established function of the target response in all six cases and produced no iatrogenic effects. The SCA produced differentiated results in all cases and iatrogenic effects (i.e., an additional function) in three of six cases. We discuss these findings in terms of the mechanisms that may promote iatrogenic effects.  相似文献

In their review of synthesis within the functional analysis (FA) literature, Slaton and Hanley (2018) reported that most synthesized contingency analyses have included multiple topographies of problem behavior in the reinforcement contingency class. This leaves the question of whether one, some, or all forms of problem behavior are sensitive to the synthesized reinforcement contingencies in published analyses. To address this ambiguity, all topographies of problem behavior that were reported by caregivers to co-occur with the most concerning problem behavior were analyzed for 10 participants. We implemented extinction across one or more forms of problem behavior to determine whether all forms reported to co-occur were sensitive to the same synthesized reinforcement contingency. For nine of 10 participants, the most concerning topographies were sensitive to the same synthesized reinforcement contingencies as the less concerning topographies (results were inconclusive for one). Implications for inferring response class membership from single analyses are discussed.  相似文献

Latency‐based functional analysis (FA) may be a viable alternative to the standard, rate‐based, FA when frequently evoking problem behavior is not advisable. We conducted 18 latency‐based FAs of the problem behavior of children diagnosed with autism in inpatient hospital settings and identified functional relations during 44.4% (8 of 18) of latency‐based FAs. Implications for conducting FAs of severe problem behavior are discussed.  相似文献

Research has demonstrated the feasibility of using positive reinforcement to treat problem behavior maintained by negative reinforcement. This line of research was extended in the current study. A functional analysis (FA) was conducted that suggested problem behavior was maintained by positive and negative reinforcement. Following the FA, a demand analysis was conducted with three demand conditions: one that replicated the demand condition from the FA, one that included presession exposure to a preferred item, and another that included presession exposure to preferred items and access to those items during breaks from demands. Although problem behavior occurred in all three demand conditions, within session analyses showed that problem behavior ceased during breaks from demands only when they included access to preferred items. This finding suggests that the motivating operation responsible for evoking problem behavior did not decrease when only a break was provided. Subsequent functional communication training and treatment analysis showed that treatments based on positive reinforcement were effective at reducing problem behavior, but those based on a negative reinforcement hypothesis were not.

Although decades of research on functional analysis methodology have identified common contingencies that maintain problem behavior and effective interventions, relatively little research has been conducted on strategies to prevent the initial development of problem behavior. We conducted a 2‐part case study, the purposes of which were to illustrate the use of sensitivity tests as the bases for intervention (Study 1) and subsequently to assess the efficacy of a prevention strategy using a single‐subject design (Study 2). Results showed that the sensitivity tests identified establishing operations that may set the occasion for the development of problem behavior and that interventions based on differential reinforcement prevented increases in the severity of problem behavior relative to untreated and control baselines. Benefits and limitations to this individualized approach to prevention are discussed.  相似文献

In the typical functional analysis in which the antecedent and consequent events associated with problem behavior are manipulated, the control condition involves elimination of both the relevant establishing operation (EO) and its associated contingency through a schedule of noncontingent reinforcement (usually fixed-time [FT] 30 s). In some functional analyses, however, antecedent events are manipulated in the absence of differential consequences, and a common test condition in such analyses also involves the delivery of reinforcement on an FT 30-s schedule. Thus, the same schedule of reinforcement (FT 30 s) is not considered to be an EO in the former type of analysis but is considered to be an EO in the latter. We examined the relative influences of EOs and reinforcement contingencies on problem behavior by exposing 6 individuals who engaged in self-injurious behavior (SIB) to four combinations of functional analysis conditions: EO present/contingency present, EO absent/contingency present, EO present/contingency absent, and EO absent/contingency absent. Results indicated that the only condition in which high rates of SIB were observed consistently was one in which the EO and the reinforcement contingency were both present. Implications of these results for the design of functional analysis test and control conditions are discussed.  相似文献

Many researchers provide praise for complying with demands during the escape condition of the functional analysis (FA). However, praise may function as a reinforcer for some individuals which may reduce the aversiveness of task presentation or increase behavior that competes with problem behavior (e.g., compliance with demands). In general, this may result in lower or less stable levels of problem behavior and decrease the efficiency of the FA. Thus, the purpose of the current study was to evaluate some effects of praise on the rate of problem behavior and compliance during the escape condition of the FA in children diagnosed with autism spectrum disorder. We found that praise did not affect the rate of problem behavior but did increase compliance in three of five subjects. The results of the study and implications for the assessment of problem behavior are discussed.  相似文献

We measured the effects of divided attention on the aggressive behavior of a 20‐year‐old man within a test‐control functional analysis (FA; Iwata, B. A., Duncan, B. A., Zarcone, J. R., Lerman, D. C., & Shore, B. A. (1994). A sequential, test‐control methodology for conducting functional analyses of self‐injurious behavior. Behavior Modification, 18, 289–306). The FA confirmed that divided attention was associated with high‐frequency aggression and aggression‐contingent attention from a familiar and preferred staff person. A subsequent treatment evaluation confirmed that aggression decreased when the man was able to request attention from the staff person under the divided attention condition. We discuss the clinical utility of a divided attention and test‐control methodology when conducting a FA of serious problem behavior within applied settings Copyright © 2014 John Wiley & Sons, Ltd.  相似文献

Under naturally occurring conditions, the individual who is the target of aggression is likely to physically react to evade the aggressor and avoid physical harm. Like other forms of attention that occur following problem behavior, physical reactions may maintain problem behavior. However, evaluating the effects of physical reactions is complicated by issues related to therapists' ability to consistently and safely control their reactions, which may prove difficult to achieve in functional analyses. We evaluated the utility of a concurrent‐operant analysis to test behavioral sensitivity to physical reactions. The results suggest that the concurrent‐operant analysis may be useful when therapists cannot consistently refrain from responding contingent on problem behavior in the control condition of a more typical functional analysis.  相似文献

We conducted this study to determine if the efficiency of the functional analysis could be improved without detrimental effects on control. In Experiment 1, we reanalyzed functional analyses conducted for the problem behavior of 18 children. We analyzed rates of problem behavior during the first 5 min and first 3 min of the original 10-min sessions and evaluated if changes in the level of control over problem behavior by the programmed contingency were evident from the analyses of shorter session duration. In Experiment 2, we conducted 8 consecutive functional analyses with 3-min sessions to further evaluate the utility of brief session durations. We found that control over problem behavior was demonstrated when conducting functional analyses with sessions as brief as 3 min.  相似文献
