What is alternating treatments design?
Alternating Treatments Design • Compares the effects of two or more treatments on the same behavior. • Answers the question “Is one treatment more effective than another?” • The purpose is to determine which condition is more effective in changing one behavior.
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.
What is the purpose of alternation in behavior therapy?
• The purpose is to determine which condition is more effective in changing one behavior. • Basic concept: When two or more treatments are alternated rapidly in time, you can evaluate the relative effects of the treatments. 3.
How are the results from a functional analysis graphed?
The results from a functional analysis are graphed using an alternating treatments design.

So you highlight the data you want to create a line graph. So we go to charts.
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.

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.
How many reversals are there in an ABAB design?
1 Reversal1 Reversal or ABAB design.
What is ABAB graph?
In an ABAB Reversal design, an experimenter rotates two or more conditions and has a participant complete several consecutive sessions in each condition. Typically, an experimenter rotates baseline and intervention conditions.
What is alternating treatment design?
The alternating treatment design (ATD) consists of rapid and random or semirandom alteration of two or more conditions such that each has an approximately equal probability of being present during each measurement opportunity.
How do you read ABAB graphs?
Graphs have two axes, the lines that run across the bottom and up the side. The line along the bottom is called the horizontal or x-axis, and the line up the side is called the vertical or y-axis. The x-axis may contain categories or numbers. You read it from the bottom left of the graph.

What is a changing criterion design ABA?
This is a type of experimental design in which some dimension of a behavior is systematically changed through the use of reinforcement and pre-set criterion changes.
How does a changing criterion design demonstrate a functional relationship between the variables?
In a changing criterion design, target behavior levels must meet or exceed each criterion, in sequence, but do so in a relatively stable fashion to demonstrate a functional relation. Highly variable data weaken the internal validity of the results.
How to implement alternating treatment?
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.
How many alterations are required for ATD?
ATD requires a minimum of two alterations per data series.
What is an ATD?
The alternating treatment design (ATD) consists of rapid and random or semirandom alteration of two or more conditions such that each has an approximately equal probability of being present during each measurement opportunity. As an example, it was observed during a clinical training case that a student therapist, during many sessions, would alternate between two conditions: leaning away from the client and becoming cold and predictable when he was uncomfortable, and leaning towards the client and becoming warm and open when feeling comfortable. The client would disclose less when the therapist leaned away, and more when he leaned forward. If it were assumed that the therapist had preplanned the within-session alternations, an ATD as shown in Figure 6 would be obtained. The condition present in the example at any given time of measurement is rapidly alternating. No phase exists; however, if the data in each respective treatment condition are examined separately, the relative level and trend of each condition can be compared between the two data series (hence the name between-series designs).
What is Snyder and Shaw's methodology?
Snyder & Shaw (this volume) provide a substantive discussion of the use of single-case experimental designs (also referred to as “small-n designs”) to answer an assortment of questions about sexuality. Nonetheless, we believe that the use of single-case experimental methodology to answer questions regarding childhood sexuality is of sufficient importance to warrant some discussion here.
What is single case design?
Although usually labeled a quasi-experimental time-series design, single-case research designs are described in this article as a separate form of research design (formerly termed single-subject or N = 1 research) that have a long and influential history in psychology and education (e.g., Kratochwill, 1978; Levin et al., 2003) and can serve as an alternative to using large, aggregate group designs ( Shadish and Rindskopf, 2007 ). Single-case research designs bear similarly to time-series design and have often been regarded as quasi-experimental because they usually do not (but could) include randomization in the experiment. In the single-case design, replication is scheduled to help rule out various threats to validity. Single-case designs can involve a single participant or group as the unit but differ from repeated measures and hierarchical linear modeling (HLM) designs because multiple observations are taken over a long period of time within a design structure of replication and/or randomization of the conditions of the experiment.
What is simultaneous treatment?
The same is true for simultaneous-treatment designs; a design that is appropriate for situations where one wishes to evaluate the concurrent or simultaneous application of two or more treatments in a single case. Rapid or random alteration of treatment is not required with simultaneous-treatment design.
When to use ATDs?
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.
