The effects of consequence manipulation during functional analysis of problem behavior maintained by negative reinforcement

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.     

Topographical and functional properties of precursors to severe problem behavior

A literature search identified 17 articles reporting data on 34 subjects who engaged in precursors to severe problem behavior, which we examined to identify topographical and functional characteristics. Unintelligible vocalization was the most common precursor to aggression (27%) and property destruction (29%), whereas self- or nondirected movement was the most common precursor to SIB (32%). Unintelligible vocalization and object-directed movement were the most common precursors to behavior maintained by social-positive reinforcement (27% each), and unintelligible vocalization was the most common precursor to behavior maintained by social-negative reinforcement (29%). Only one precursor was reported for behavior maintained by automatic reinforcement.     

Functional analyses and treatment of precursor behavior

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.     

Functional analysis of aberrant behavior through measurement of separate response topographies

Functional analysis results for multiple topographies of aberrant behavior were graphed in an aggregate fashion and then separately for 48 clients. The results indicated that multiple topographies of behavior may be maintained by different contingencies. These results indicate that graphing functional analysis data in an aggregate fashion and then separately may improve the accuracy of their interpretation.     

Parent‐conducted rapid assessment of attention types for the treatment of attention‐maintained problem behavior

When praise is not a reinforcer for alternative behavior in the treatment of attention‐maintained problem behavior, further pretreatment assessments are warranted to develop an effective treatment. The current study reports a replication of the pretreatment rapid assessment of attention types (RAAT) procedures, implemented by the parents of a 19‐year‐old female with attention‐maintained problem behavior. After administering staff and parent‐conducted RAATs, a parent‐implemented treatment, (a) produced clinically significant decreases in problem behavior, and (b) confirmed that the RAAT identified an attention‐type that served as a reinforcer for appropriate alternative behavior. This study extends the findings of Strohmeier et al. by reporting results of a parent‐conducted RAAT and treatment evaluation. The findings highlight the practical importance of pretreatment assessment of attention‐types, with emphasis on caregiver involvement, to develop effective treatments for attention‐maintained problem behavior.     

Identification of environmental determinants of behavior disorders through functional analysis of precursor behaviors

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.     

Interview‐informed functional analyses: A comparison of synthesized and isolated components

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.     

Functional analysis in public schools: a summary of 90 functional analyses

Several review and epidemiological studies have been conducted over recent years to inform behavior analysts of functional analysis outcomes. None to date have closely examined demographic and clinical data for functional analyses conducted exclusively in public school settings. The current paper presents a data-based summary of 90 functional analyses conducted in public school settings from 2006 through 2009 for 69 students. Specifically, we present data on gender, age, race, diagnosis, topography of target behaviors, number of conditions, duration of sessions, duration of analysis, functional outcomes, setting, and person serving the role of therapist. Results suggest that functional analyses in schools are possible, practical, and produce results that are comparable to those in past research.     

Further investigation of differential reinforcement of alternative behavior without extinction for escape‐maintained destructive behavior

Previous research indicates that manipulating dimensions of reinforcement during differential reinforcement of alternative behavior (DRA) for situations in which extinction cannot be implemented is a potential approach for treating destructive behavior. Therefore, we replicated and extended previous research by determining (a) the conditions under which DRA without extinction decreased and maintained low levels of destructive behavior and (b) whether intervention effects maintained during reinforcement schedule thinning for the alternative response (i.e., compliance). Results showed that effective treatments were developed in the absence of extinction by manipulating the quality of reinforcement for compliance for 2 participants and by combining manipulations of the magnitude and quality of reinforcement for compliance for the other 2 participants. However, maintaining treatment effects during reinforcement schedule thinning required combining the magnitude and quality of reinforcement for 3 of the 4 participants. We discuss the clinical utility of this approach, review limitations of the study, and suggest directions for future research.     

The effects of response cost in the treatment of aberrant behavior maintained by negative reinforcement

Positive reinforcement contingencies can sometimes be used to decrease problem behavior maintained by negative reinforcement (e.g., escape). In the current study, we evaluated the extent to which response cost (i.e., contingent removal of a preferred stimulus) would compete with the negative reinforcer maintaining destructive behavior. The response cost contingency reduced destructive behavior by 87% from baseline levels even though the negative reinforcement contingency (i.e., escape) remained in place.     

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.     

Predictive validity and efficiency of ongoing visual‐inspection criteria for interpreting functional analyses

Prior research has evaluated the reliability and validity of structured criteria for visually inspecting functional‐analysis (FA) results on a post‐hoc basis, after completion of the FA (i.e., post‐hoc visual inspection [PHVI]; e.g., Hagopian et al., 1997). However, most behavior analysts inspect FAs using ongoing visual inspection (OVI) as the FA is implemented, and the validity of applying structured criteria during OVI remains unknown. In this investigation, we evaluated the predictive validity and efficiency of applying structured criteria on an ongoing basis by comparing the interim interpretations produced through OVI with (a) the final interpretations produced by PHVI, (b) the authors’ post‐hoc interpretations (PHAI) reported in the research studies, and (c) the consensus interpretations of these two post‐hoc analyses. Ongoing visual inspection predicted the results of PHVI and the consensus interpretations with a very high degree of accuracy, and PHAI with a reasonably high degree of accuracy. Furthermore, the PHVI and PHAI results involved 32 FA sessions, on average, whereas the OVI required only 19 FA sessions to accurately identify the function(s) of destructive behavior (i.e., a 41% increase in efficiency). We discuss these findings relative to other methods designed to increase the accuracy and efficiency of FAs.     

Precursor behavior and functional analysis: A brief review

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.     

Response latency as an index of response strength during functional analyses of problem behavior

Dependent variables in research on problem behavior typically are based on measures of response repetition, but these measures may be problematic when behavior poses high risk or when its occurrence terminates a session. We examined response latency as the index of behavior during assessment. In Experiment 1, we compared response rate and latency to the first response under acquisition and maintenance conditions. In Experiment 2, we compared data from existing functional analyses when graphed as rate versus latency. In Experiment 3, we compared results from pairs of independent functional analyses. Sessions in the first analysis were terminated following the first occurrence of behavior, whereas sessions in the second analysis lasted for 10 min. Results of all three studies showed an inverse relation between rate and latency, indicating that latency might be a useful measure of responding when repeated occurrences of behavior are undesirable or impractical to arrange.     

Relative influences of establishing operations and reinforcement contingencies on self-injurious behavior during functional analyses

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.     

Use of a paired-stimulus demand analysis to evaluate demands for inclusion in functional analyses

Clinicians regularly use both indirect and direct assessments to identify preferred stimuli to include in control conditions and positive reinforcement test conditions in a functional analysis (FA). However, clinicians often rely on indirect assessment alone (e.g., caregiver report) to identify aversive stimuli to include in negative reinforcement test conditions. In this study, we evaluate a paired-stimulus demand analysis and validate assessment results via FA. Results indicate that, for all 4 participants, the demands selected least often evoked higher rates of destructive behavior than more frequently selected demands. We identified an escape function for all 4 participants in the escape–least selected (LS) condition (true positive finding) and for only 1 participant in the escape–most selected (MS) condition (false negative finding for 3 of 4 participants). These results support the utility of empirically deriving stimuli for inclusion in the negative reinforcement test condition of an FA to decrease the likelihood of false negative findings.     

Further evaluation of leisure items in the attention condition of functional analyses

Research suggests that including leisure items in the attention condition of a functional analysis may produce engagement that masks sensitivity to attention. In this study, 4 individuals' initial functional analyses indicated that behavior was maintained by nonsocial variables (n = 3) or by attention (n = 1). A preference assessment was used to identify items for subsequent functional analyses. Four conditions were compared, attention with and without leisure items and control with and without leisure items. Following this, either high- or low-preference items were included in the attention condition. Problem behavior was more probable during the attention condition when no leisure items or low-preference items were included, and lower levels of problem behavior were observed during the attention condition when high-preference leisure items were included. These findings suggest how preferred items may hinder detection of behavioral function.
