What is the alternating treatment design in abab?
In the alternating treatment design, following a baseline phase, the treatments are alternated in rapid succession (compared to the ABAB design which has more within phase observations or measurements) allowing a comparison of the treatment to baseline or an alternative treatment over repeated observations (e.g., ABABABABAB and ABCBCBCBC).
Is ABA better than eclectic early interventions?
Summary: ABA is better than eclectic, even when eclectic methods are used to the same intensity. This important Howard study is good for tribunals. Read here Title: Comparison of Behavior Analytic and Eclectic Early Interventions for Young Children with Autism After Three Years
Can alternating treatment phases be counterbalanced or randomized?
The alternating treatment phases can be counterbalanced or randomized. In each of these designs the researcher must attend to various features of the data, including mean changes among phases, trend, variability, and autocorrelation in the data.
How do you design an alternating treatments design?
To implement an alternating treatments design, begin as usual with a brief baseline, simply to ensure that the client actually needs intervention to eat those foods. You then alternate meals back and forth between the two different treatments that you want to evaluate.

What is an example of an alternating treatment design?
For example, a researcher comparing two methods for eliminating the disruptive classroom behavior of a student might have the teacher use one method throughout the morning and the other method throughout the afternoon and then evaluate the student's behavior with each technique.
When do we use alternating treatment design in ABA?
Alternating Treatment DesignEfficiently compares intervention effectiveness.It does not require withdraw.It can be used to assess generalization effects.It does not include a return to baseline.It often doesn't include a baseline to begin with.
Is alternating treatment design a single subject design?
Another variation of the single-case design that is becoming increasingly recognized for its versatility is the alternating treatment design (ATD) (Barlow and Hayes 1979).
What is a limitation of the alternating treatments design?
limitation of alternating treatment designs: o it is susceptible to multiple treatment interference, o rapid back-and-forth switching of treatments does not reflect the typical manner in which interventions are applied and may be viewed as artificial and undesirable.

What is an ABAB study?
An ABAB research design, also called a withdrawal or reversal design, is used to determine if an intervention is effective in changing the behavior of a participant. The design has four phases denoted by A1, B1, A2, and B2. In each phase, repeated measurements of the participant's behavior are obtained.
What is the fifth guideline when using an ABAB design?
The fifth requirement concerns those extraneous factors that might be associated with , or at least present during, the intervention condition and are not shared with the control condition.

What is a reason that alternating treatments designs may have good internal validity?
The patterns of response vary with the alternating treatment conditions, so there is minimal overlap among data in the conditions and if one treatment is consistently associated with an improved level of responding, then the design demonstrates good experimental control.
What is adapted alternating treatment design?
The adapted alternating treatments design is a commonly used experimental design in skill acquisition research. This design allows for the evaluation of two or more independent variables on responding to unique target sets. Equating target sets is necessary to ensure a valid comparison of the independent variables.
What is the difference between a multi element design and an alternating treatment design?
A multielement design is also known as an alternating treatments design, because it measures the effect of multiple treatments delivered one after the other. For instance, two treatments may be compared in order to see which is most efficient in producing the target behavior.

Abstract
We propose the use of a combined version of the alternating treatments and multiple baseline designs in situations in which a traditional baseline (no treatment) condition either does not provide an adequate contrast condition or is not feasible or practical due to clinical constraints.

How to identify empirically supported treatments?
Empirically supported treatments (EST) are identified through a particular form of systematic literature review. Systematic reviews bring a rigorous methodology to the process of reviewing research. The development and use of these methods are, in part, a response to the recognition that the process of reviewing the literature is subject to threats to validity. The systematic review process is characterized by explicitly stated and replicable methods for (a) searching for studies, (b) screening studies for relevance to the review question, (c) appraising the methodological quality of studies, (d) describing outcomes from each study, and (e) determining the degree to which the treatment (or treatments) is supported by the research. When the evidence in support of a treatment is plentiful and of high quality, the treatment generally earns the status of an EST. Many systematic reviews, however, find that no intervention for a particular problem has sufficient evidence to qualify as an EST.
Why are there no ESTs in behavior analysis?
Behavior analysts encounter many situations in which no ESTs have been established for the particular combination of client characteristics, target behaviors, functions, contexts, and other parameters for decision-making. This dearth may exist because no systematic review has addressed the particular problem or because a systematic review has been conducted but failed to find any well-supported treatments for the particular problem. For example, in a recent review of all of the recommendations in the empirically supported practice guides published by the IES, 45 % of the recommendations had minimal support (Slocum et al. 2012b ). As Smith noted ( 2013 ), only 3 of the 11 interventions that the NAC identified as meeting quality standards might be considered practices in the sense that they are manualized. In these common situations, a behavior analyst cannot respond by simply selecting an intervention from a list of ESTs. A comprehensive EBP of ABA requires additional strategies for reviewing research evidence and drawing practice recommendations from existing evidence—strategies that can glean the best available evidence from an imperfect research base and formulate practice recommendations that are most likely to lead to favorable outcomes under conditions of uncertainty.
What is EBP in ABA?
EBP is an explicit statement of one of ABA’s core tenets—a commitment to evidence-based decision-making.
What is evidence based practice?
Evidence-based practice (EBP) is a model of professional decision-making in which practitioners integrate the best available evidence with client values/context and clinical expertise in order to provide services for their clients. This framework provides behavior analysts with a structure for pervasive use of the best available evidence in the complex settings in which they work. This structure recognizes the need for clear and explicit understanding of the strength of evidence supporting intervention options, the important contextual factors including client values that contribute to decision making, and the key role of clinical expertise in the conceptualization, intervention, and evaluation of cases. Opening the discussion of EBP in this journal, Smith ( The Behavior Analyst, 36, 7–33, 2013) raised several key issues related to EBP and applied behavior analysis (ABA). The purpose of this paper is to respond to Smith’s arguments and extend the discussion of the relevant issues. Although we support many of Smith’s ( The Behavior Analyst, 36, 7–33, 2013) points, we contend that Smith’s definition of EBP is significantly narrower than definitions that are used in professions with long histories of EBP and that this narrowness conflicts with the principles that drive applied behavior analytic practice. We offer a definition and framework for EBP that aligns with the foundations of ABA and is consistent with well-established definitions of EBP in medicine, psychology, and other professions. In addition to supporting the systematic use of research evidence in behavior analytic decision making, this definition can promote clear communication about treatment decisions across disciplines and with important outside institutions such as insurance companies and granting agencies.
What is clinical expertise?
Clinical expertise is the means by which the best available evidence is applied to individual cases in all their complexity. Based on the work of Goodheart ( 2006 ), we suggest that clinical expertise in EBP of ABA includes (a) knowledge of the research literature and its applicability to particular clients, (b) incorporation of the conceptual system of ABA, (c) breadth and depth of clinical and interpersonal skills, (d) integration of client values and context, (e) recognition of the need for outside consultation, (f) data-based decision making, and (g) ongoing professional development. In the sections that follow, we describe each component of clinical expertise in ABA.
Why is multicomponent treatment important?
We concur that the multicomponent treatment package is a particularly significant and strategic unit of treatment because it specifies a suite of procedures and exactly how they are to be used together to solve a problem. Validated treatment packages are far more than the sum of their parts. A well-developed treatment package can be revised and optimized over many iterations in a way that would be difficult or impossible for a practitioner to accomplish independently. In addition, research outcomes from implementation of treatment packages reflect the interaction of the components, and these interactions may not be evident in the research literature on the individual components. Further, research on the outcomes from multicomponent packages can evaluate broader and more socially important outcomes than is generally possible when evaluating more narrowly defined treatments. For example, in the case of teaching a child with autism to communicate, research on a focused procedure such as time delay may indicate that its use leads to more independent communicative responses; however, research on a comprehensive Early Intensive Behavioral Intervention can evaluate the impact of the program on children’s global development or intellectual functioning.
What is the best available evidence?
The term “best available evidence” occupies a critical and central place in the definition and concept of EBP; this aligns with the fundamental reliance on scientific research that is one of the core tenets of ABA. The Behavior Analyst Certification Board ( 2010) Guidelines for Responsible Conduct for Behavior Analysts repeatedly affirm ways in which behavior analysts should base their professional conduct on the best available evidence. For example:
How to search for studies in ABA?
To search specifically for studies carried out in the field of Applied Behavior Analysis, we enter in the titles of the ABA journals, strung together, with OR in between. The quotation marks ensure each title is searched as a phrase. Choosing "SO Publication Name" in the drop-down menu ensures that results will be from articles published in those journals (not just references to those journals).

How to detect multiple treatment interference?
Several procedures exist to help detect multiple treatment interference (Sidman, 1960). A simple phase change where one treatment condition is preceded by a baseline phase, when compared to another AB design containing the other treatment, and finally compared to an ATD combining both conditions, could be used to parse out the separate and interactive effects of the treatment conditions. Alternatively, the intensity of one treatment condition could be increased, with any subsequent changes in the following conditions (as compared to changes already witnessed in an ATD containing both conditions) attributable to carry-over effects.
Why use ATD?
One of the benefits of the ATD is the simplicity with which it can be used to compare three or even more treatment conditions. Proper comparisons of three conditions in a within-series design can be difficult due to counterbalancing concerns, order effects, and the sheer number of phase changes that need to be executed over a relatively long period of time. With an ATD, three or even more conditions can be presented in a short time. The rapid and random alternations between conditions makes order effects less likely, but multiple treatment interference (the impact of one treatment is different due to the presence of another) is arguably likely. ATDs are ideally used with behaviors emitted at a relatively high frequency that correspondingly allows many instances of each alternate intervention to be applied. However, the design may be used with relatively infrequent behaviors if data is collected for a longer period of time. In addition, behaviors that tend not to have an impact for long after a discrete intervention is made and withdrawn make better targets for an ATD. If a change initiated by such a discrete intervention continues over a long period of time, effects of subsequent interventions are obscured and reliable data interpretation is often not possible.
How to reduce stereotypic behavior in retarded people?
In this study, two methods of reducing stereotypical behavior (e.g., rocking, hand-flapping) in retarded subjects were examined: gentle reaching (the use of social bonding and gentle persuasion with the developmentally disabled) and visual screening (covering the client's eyes for a few seconds following stereotypic behavior, thus reducing visual stimulation including that provided by these movements). Each of the two conditions were randomly alternated with a baseline condition. After a baseline period, visual screening produced a dramatic reduction in stereotypy, whereas gentle teaching had only a transient effect.
What are the advantages of ATD?
ATDs hold several other advantages over standard within-series designs. First, treatment need not be withdrawn in an ATD—if treatment is periodically withdrawn, it can be for relatively short periods of time. Second, comparisons between components can be made more quickly. If a clear favorite emerges early in a well-conducted ATD, the clinician can be reasonably sure that its comparative efficacy will be maintained McCullough, Cornell, McDaniel, and Mueller (1974), for example, compared the relative efficacy of two treatments in four days using an ATD. ATDs can be used without collecting baseline data, or with baseline data through the creation of a concurrent baseline data series. Any background within-series trends (such as those due to maturation of the client or etiology of the disorder) are unlikely to obscure interpretation of the data because the source of data comparisons are purely between series, not within.
Why was the supplement of self-management to standard coaching in Wolko et al. (1993)?
The supplement of self-management to standard coaching in Wolko et al. (1993) improved balance beam performance of the gymnasts. This improvement was gradual, possibly because “the time span allotted for each condition to show its effect may have been too brief” (p. 220). The results also suggested that the private self-goal setting and self-monitoring combination was marginally more effective than the publically implemented procedures. This study also reported social validity assessment indicating that the gymnasts liked both self-management interventions more than standard coaching.
How to compare acquisition across two symbol types?
To directly compare acquisition across the two symbol types, Hurlbut and colleagues (1982) used an adapted alternating treatments design (AATD; Sindelar, Rosenberg, & Wilson, 1985 ). As with the traditional alternating treatments design, the AATD involves rapid alternation between two or more assessment or intervention conditions, so that the vertical separation between data paths can be assessed across the entire length of the phase. The adapted part of the design is that, rather than maintaining the same dependent variable across the conditions, a different set of responses is assigned to each intervention or assessment condition. In the Hurlbut study, the researchers identified common objects (e.g., sock, door) that were known to the participants (i.e., the participants could identify the correct label in a “yes” or “no” format), and assigned sets of five objects to the conditions, with assignment counterbalanced across participants. By maintaining the same instructional methods across the two conditions, the authors were able to determine that the iconic symbols were associated with substantially faster rates of acquisition for all three participants. In addition, the iconic symbols resulted in greater maintenance over time, more stimulus generalization, and more spontaneous use than the Bliss symbols for all the participants. These results led to the conclusion that the iconic system had several advantages over the Bliss symbols for beginning communicators.
