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.
Full Answer
Which behavior is introduced sequentially in a treatment program?
A treatment program is then introduced sequentially on the name calling behavior, then the swearing behavior, and finally the spitting behavior. This is a( n) __________ design: multiple-baseline across behaviors
What is multiple baseline design in psychology?
The multiple-baseline design involves replication across participants, settings, or behaviors in a single participant or groups. In this design, the treatment is staggered and introduced sequentially in a time-lagged fashion usually on at least three separate series, although more add credibility to causal inference.
What are the terms in the behaviour modification exam 3?
Behavior modification exam 3 set Terms in this set (85) Reversal-replication research design includes a reversal to baseline conditions followed by a replication of the treatment phase ABAB design same as a reversal-replication in that the baseline condition is abbreviated as "A" and the treatment condition as "B"
Can alternating treatments design be used to study behavior?
It is possible to use the alternating treatments design to study topographically different forms of the behavior. True Judgments about the clinical or applied importance of behavior change are referred to as judgments of external validity.
What is a multiple baseline design across behaviors?
For the multiple-baseline-across-behaviors design, multiple behaviors of the same individual are studied. In the settings design, an individual's behavior is studied across multiple settings and situations. Lastly, in the multiple-baseline-across-subjects design, the same behavior is studied for multiple individuals.
What type of assessment can the alternating treatment design be used for?
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.
Which best describes an alternating treatment design?
Which best describes an alternating treatment design? Multiple interventions are introduced repeatedly in an alternating pattern. These data are compared in order to determine which intervention is most effective.
Why is ABAB design typically superior to AB design?
Why is an ABAB design superior to an ABA design? The ABAB design is superior to the ABA design because a single reversal is not strong enough for the effectiveness of the treatment. Also the sequence ends with the treatment rather than with people withdrawing from the treatment.
What are treatment designs?
a type of study in which the experimental condition or treatment assigned to the participant changes from session to session or within sessions.
What is a multiple treatment design?
In a multiple-treatment reversal design , a baseline phase is followed by separate phases in which different treatments are introduced.
What type of treatment design is also called the concurrent schedules design?
Alternating treatment design is also known as multi-element design, multiple schedule design, concurrent schedule design, and simultaneous treatment design. This design compares two or more distinct treatments while their effects on the target behavior are measured.
What is a multielement 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.
What is an example of multiple-baseline design?
Multiple-Baseline Design Across Settings For example, a baseline might be established for the amount of time a child spends reading during his free time at school and during his free time at home. Then a treatment such as positive attention might be introduced first at school and later at home.
What is AB ABA ABAB design?
A-B-A-B Design. The A-B-A-B design represents an attempt to measure a baseline (the first A), a treatment measurement (the first B), the withdrawal of treatment (the second A), and the re-introduction of treatment (the second B).
What is ABAB reversal design?
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. This design is useful for demonstrating functional relations with performance behaviors.
What is the difference between ABA design and ABAB design?
The ABA design can help find effective treatment methods and models. The ABAB method reintroduces the intervention to help end on a positive note as the therapy is brought back.
What is the variable and the behavior being treated referred to as?
variable and the behavior being treated is referred to as the independent variable.
Why does alternating therapy produce an effect?
produce an effect either because of a contrast to the other treatment in alternating sessions or because of generalization of treatments across conditions.
What is single case design?
Single-case designs are based on assumptions about the distribution of the dependent variable in the population.
When should baseline phase continue?
A baseline phase should continue until the pattern of performance is stable or until it shows a trend in the direction opposite to that predicted for treatment.
How many replications of each phase are necessary to draw a valid conclusion?
design, two replications of each phase are necessary to draw a valid conclusion.
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.
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.
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.
What are the disadvantages of sequential treatment?
Although sequential treatment has the advantage of providing an increased level of attention to the more acute disorder, a typical disadvantage of this model is that patients are often transferred to a different treatment team to address the less acute disorder, and the interrelationship between the two disorders may never be adequately addressed.
What is integrated treatment?
In integrated treatment, the management of both disorders occurs in one treatment setting, and the same clinicians, or team of clinicians, manage both illnesses. Integrated treatment has received increasing interest of researchers and clinicians, fostered by the belief that it is more effective than the other treatment models described earlier.
What are some examples of substance abuse?
For example, in substance abuse treatment programs, clinicians may attribute psychiatric symptoms (e.g., depression and anxiety) to substance use; when a patient attempts to obtain relief, they may view this as "drug-seeking" behavior.
Can the same staff treat both disorders?
The same staff may treat both disorders, or the less acute disorder may be treated after transfer to a different program or facility. For example, a manic patient with a cocaine use disorder needs mood stabilization before initiating substance abuse treatment.
Can patients be treated in parallel?
Unfortunately, patients treated in parallel or sequential programs often receive different experiences based on the treatment settings they enter. The two different programs may provide patients with different feedback on the relationship between their substance use and psychological symptoms.
Can you treat SUD in parallel?
In parallel treatment, both disorders are treated simultaneously, but not by the same treatment team. For example, a patient may receive treatment for an SUD in an addiction treatment program and for a psychiatric disorder in a mental health clinic.
