Increasing the Social Validity of Function-Based Treatments for Problem Behavior

Jessica P. Álvarez; Nathan A. Call; Joanna Lomas Mevers

Functional assessment, and function-based treatments, are the gold standard for the treatment of problem behavior. Historically, these assessment and treatment evaluations have been conducted in austere clinical settings to increase internal validity. While prioritizing internal validity is critical in the initial stages of a treatment evaluation, if there is not an eventual shift to prioritizing the external or social validity of the treatment it may inevitably fail in the natural environment. The purpose of this case example is to outline a socially valid approach to the assessment and treatment of problem behavior that ensures individuals’ and their families’ lives benefit in meaningful ways. More specifically, this case-example will outline a method of prioritizing social validity to identify treatment goals, conduct functional analysis, evaluate and generalize treatment, and implement caregiver training.

Prior research on treatment integrity has focused either on the lack of measurement of the independent variable or on methods to increase overall levels of treatment integrity. Little research has focused on the effectiveness of common interventions when implemented with less than perfect integrity. The current investigation evaluated the effectiveness of using differential reinforcement of alternative behavior (DRA) and prompting to increase math completion for 36 early elementary students. Treatment was evaluated when both components were implemented, when only reinforcement was implemented, when only prompting was implemented, and when neither was implemented. In addition, preferences for either attention or escape and order-effects of conditions were evaluated. Results indicated treatment was effective at all levels of implementation compared to baseline. However, when preferences for escape and attention were evaluated, analysis revealed individuals who preferred escape responded best when both treatment components were implemented, whereas for individuals who preferred attention, all treatment conditions were equally effective. In addition, results evaluating order effects indicated that exposure to either prompting or reinforcement prior to baseline significantly increased math completion as well as exposure to reinforcement in the first condition.

Functional Behavioral Assessments

Nathan A. Call; Mindy Scheithauer; Joanna Lomas Mevers

Abstract Research has demonstrated that interventions for problem behaviors are more effective when treatment components are selected to match the consequences that maintain the individual’s behavior (i.e., its function). However, many methods for identifying the function of an individual’s problem behavior appear in the literature. The functional analysis (FA) methodology first introduced by Iwata et al. is the most comprehensive and well-studied. However, a variety of factors may prevent a clinician from conducting this type of FA. This chapter describes many of the functional assessment procedures that appear in the literature, including the advantages and disadvantages of each. In addition to various formats of FA, the relative strengths and weaknesses of indirect assessments and descriptive assessments are discussed, as well as the most appropriate applications for each.

ABSTRACT Children with developmental disabilities (DD) are more likely than typically developing peers to have issues with enuresis. Past research has shown the success of behavioral treatments consisting of scheduled sits and reinforcement for continent voids. However, this research has included small sample sizes, while studies with larger numbers have lacked key information (i.e., baseline rates and follow-up data to evaluate maintenance and generalization). The current study conducted a consecutive case series analysis of 44 individuals with developmental disabilities who completed a 2-week program for enuresis. Results showed significant improvement in continent voids and follow-up data suggested positive results maintained when treatment was implemented by caregivers in a home environment.

Achieving continence of ones bowel movements is a key step in development and failure to do so leads to many negative consequences. Treatments for encopresis appearing in the literature have employed behavioral strategies; medications such as suppositories, laxatives, or enemas; and in some studies a combination of these approaches. To date, attempts to extend successful treatments for encopresis in typically developing children to those with developmental disabilities have been limited. The current study included three participants diagnosed with developmental disabilities who had a history of encopresis. None of the participants had a continent bowel movement under baseline conditions. Continent bowel movements increased during treatment that included the addition of suppositories to elicit continent bowel movements. Two participants began having independent continent bowel movements (i.e., without requiring suppositories) and medication was successfully faded out for the remaining participant. Treatment took between 13 and 21 days.

ABSTRACT Purpose: This study sought to examine the correspondence between brief functional analyses and more thorough functional analyses as described in the model of functional assessment proposed by Vollmer et al.1 Methods: A panel of trained clinicians indicated the presence/absence of specific functions of problem behavior based on graphic results from brief functional analyses and functional analyses conducted with 19 participants. These conclusions were compared across assessments. Results: The functions identified by the panel based on results of brief functional analyses had low correspondence with those of the more thorough functional analysis conducted with the same participants. Conclusions: Although brief-functional analyses appear regularly in clinical practice and the literature, findings from this study suggest that results may differ from those of more thorough functional analyses. Additional study is necessary to determine the cause of discrepant results between these two methodologies.

Practice Recommendations for Addressing Problem Behaviors in Siblings with Autism Spectrum Disorder

Joanna Lomas Mevers; Nathan A. Call; Sarah J. Miller

Children with autism spectrum disorder (ASD) display an increased prevalence of problem behavior, relative to the typically developing population. Given the heritability of ASD and its growing prevalence, clinicians who implement behavioral treatments are likely to encounter families with siblings with ASD who exhibit problem behavior. Thus, there is a need for guidance for treatment of problem behavior for these families. This paper presents strategies for conducting behavioral assessments, developing treatments for problem behaviors, caregiver training, and generalization strategies when there are multiple affected children in one family. A case study is presented to illustrate the key clinical decisions made to increase the likelihood of a successful treatment outcome for these families.

The external validity of behavioral treatments for elopement (i.e. leaving supervision without permission) remains unclear because studies to date include only small samples (n = 1–3). This study quantified the overall effectiveness of behavioral treatments for elopement by retrospectively examining treatment data from all patients seen for the treatment of elopement at an intensive day treatment clinic (n = 11), irrespective of treatment success. Reductions in elopement from baseline to the final treatment for each participant demonstrate that behavioral intervention is a highly effective treatment for elopement, as determined by the large effect size (Cohen’s d = 1.18).

Unlike potential tangible positive reinforcers, which are typically identified for inclusion in functional analyses empirically using preference assessments, demands are most often selected arbitrarily or based on caregiver report. The present study evaluated the use of a demand assessment with 12 participants who exhibited escape-maintained problem behavior. Participants were exposed to 10 demands, with aversiveness measured by average latency to the first instance of problem behavior. In subsequent functional analyses, results of a demand condition that included the demand with the shortest latency to problem behavior resulted in identification of an escape function for 11 of the participants. In contrast, a demand condition that included the demand with the longest latency resulted in identification of an escape function for only 5 participants. The implication of these findings is that for the remaining 7 participants, selection of the demand for the functional analysis without using the results of the demand assessment could have produced a false-negative finding.
