We observed changes in the rates of response topographies during the demand condition of functional analyses for participants who demonstrated problem behavior maintained by escape. Over the course of the functional analysis for each participant, the number of topographies decreased from the first to the last session. Additionally, after the first session of the demand condition the rate of responding for one topography increased or remained at high levels while the rates of all other topographies decreased. The implications of these results when conducting functional analysis are discussed.  相似文献

We replicated Fritz, Iwata, Hammond, and Bloom (2013) by evaluating the efficacy of an experimental methodology to identify precursors to aggression displayed by an adolescent with autism spectrum disorder. Using their trial‐based precursor analysis, we identified seven precursors to aggression. Next, we compared the outcomes of separate precursor and aggression functional analyses and showed that both precursors and aggression were multiply controlled by the same variables.  相似文献

Researchers have developed precursor functional analyses to provide an alternative, and presumably safer, format for functional analysis of severe problem behavior. When researchers use functional analysis contingencies for precursor behaviors, it is possible to infer functional characteristics about severe problem behaviors based on patterns of less severe precursor behaviors, permitting practitioners to complete the assessment with less risk to clients, practitioners, or others. The current paper discusses recent advances in the development and validation of precursor identification, and offers suggestions and future directions for investigating and implementing precursor functional analyses. We propose a decision‐making model, in which practitioners integrate procedures to identify precursors into the functional‐analysis process, to expedite the analysis of severe problem behaviors.  相似文献

Functional analysis has been demonstrated to be an effective method to identify environmental variables that maintain problem behavior. However, there are cases when conducting functional analyses of severe problem behavior may be contraindicated. The current study applied functional analysis procedures to a class of behavior that preceded severe problem behavior (precursor behavior) and evaluated treatments based on the outcomes of the functional analyses of precursor behavior. Responding for all participants was differentiated during the functional analyses, and individualized treatments eliminated precursor behavior. These results suggest that functional analysis of precursor behavior may offer an alternative, indirect method to assess the operant function of severe problem behavior.  相似文献

Experimental analysis procedures have been shown to be effective means for identifying the environmental determinants of problem behaviors. A potential limitation of these procedures is that it is necessary to produce and document patterns in the occurrence of the problem behavior during the assessment. In the case of severe behavior disorders, this may place the participant or therapist at such risk as to preclude the analysis. The current study arranged experimental analysis contingencies for precursor behaviors that had been observed to reliably precede the occurrence of problem behaviors targeted for reduction. For each of the 4 participants, it was possible to infer the maintaining variables for problem behaviors based on the outcomes of precursor analysis. These results suggest that the current procedures represent a promising alternative method for reducing risk during functional analysis of problem behaviors.  相似文献

Two functional communication training (FCT) conditions without extinction were compared to treat the problem behavior of a child with developmental disabilities. The individual was taught to emit a single FCT response to obtain one of six items delivered in a randomized order or multiple FCT responses that specified the exact item. Results showed that only the FCT-multiple condition reduced problem behavior and maintained alternative mands.  相似文献

Two distinct analytic methods have been used to identify the function of problem behavior. The antecedent-behavior-consequence (ABC) method (Iwata, Dorsey, Slifer, Bauman, & Richman, 1982/1994) includes the delivery of consequences for problem behavior. The AB method (Carr & Durand, 1985) does not include consequence delivery, instead relying exclusively on antecedent conditions to evoke the behavior. The AB and ABC functional analysis methods were compared in this study with 4 children with developmental disabilities who engaged in task-related problem behavior. Results show that the ABC method identified an escape method for all four cases, whereas the AB method failed to identify a function for any case.  相似文献

Resurgence occurs when a previously extinguished behavior reemerges once a more recently reinforced behavior is placed on extinction. Previous research has suggested that nontargeted responses within the same response class recur alongside target-response resurgence (e.g., da Silva, Maxwell, & Lattal, 2008; Lieving, Hagopian, Long, & O'Connor, 2004). The purpose of this two-experiment investigation was to examine target response resurgence while simultaneously measuring the occurrence of nontargeted responses. Three children diagnosed with autism spectrum disorder who displayed multiple topographies of problem behavior participated. In Experiment 1, a three-phase resurgence procedure was conducted and all three participants displayed target-response resurgence accompanied by the emergence of nontargeted forms of problem behavior. These findings were replicated in Experiment 2 using a 30-min assessment procedure. The implications of these findings as they pertain to the treatment of severe problem behavior and utility of a brief relapse assessment are discussed.  相似文献

Functional analysis methodology focuses on the identification of variables that influence the occurrence of problem behavior and has become a hallmark of contemporary approaches to behavioral assessment. In light of the widespread use of pretreatment functional analyses in articles published in this and other journals, we reviewed the literature in an attempt to identify best practices and directions for future research. Studies included in the present review were those in which (a) a pretreatment assessment based on (b) direct observation and measurement of (c) problem behavior was conducted under (d) at least two conditions involving manipulation of an environmental variable in an attempt (e) to demonstrate a relation between the environmental event and behavior. Studies that met the criteria for inclusion were quantified and critically evaluated along a number of dimensions related to subject and setting characteristics, parametric and qualitative characteristics of the methodology, types of assessment conditions, experimental designs, topographies of problem behaviors, and the manner in which data were displayed and analyzed.  相似文献

It is common practice in research on the treatment of problem behavior to compare levels of targeted behaviors during treatment to levels when treatment is not in place. Some researchers use data collected as part of a multielement functional analysis as the initial baseline, whereas others collect new baseline data following completion of the functional analysis. We evaluated whether the source of baseline data influences the reliability and efficiency of decision-making. Results suggest that similar decisions are made in regard to treatment efficacy using the different sources of baseline data, but using data from a multielement functional analysis as baseline may save time. Interrater agreement was adequate, but lower for some graphs than has been observed in past studies. Several potential explanations for this discrepancy are discussed.  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

We examined the effects of three different presession conditions on tangibly maintained problem behavior for 2 students with autism, using individual-participant multielement designs. First, an analogue functional analysis demonstrated that problem behavior was maintained by access to tangible items. Next, topographies of item rejection were identified. Finally, students were exposed to (a) brief access, (b) no access, and (c) satiation to the tangible items prior to tangible sessions. The results demonstrated high levels of problem behavior following the brief-access and no-access presession conditions and low levels of problem behavior following the satiation condition. The findings are discussed in the context of how satiation might best be defined for these sorts of evaluations.  相似文献

Bowman et al. (1997) described a dynamic contingency in which severe problem behavior was evoked by adult noncompliance with a variety of child mands, which occurred at high rates, and was reinforced by adult compliance with subsequent mands. They discovered this phenomenon with 2 children for whom standard functional analyses were inconclusive. In recent years, similar contingencies have been shown to influence problem behavior, but the manner in which they have been arranged and described has varied across studies. The purpose of this literature review is to (a) describe contingencies involving mand compliance and the circumstances under which they have been evaluated, (b) summarize procedural variations in analysis and treatment, and (c) discuss what is known and yet to be discovered about the contingency as it relates to problem behavior. Future research focused on improving technology for analyzing and treating problem behavior suspected to be sensitive to mand compliance is discussed.  相似文献
