What Is Multiple Baseline Across Subjects Design? - Fixanswer

an experimental approach in which two or more behaviors are assessed to determine their initial, stable expression

(i.e., baseline) and then an intervention or manipulation is applied to one of the behaviors while the others are unaffected.

What is a multiple baseline design used for?

The multiple baseline design is useful for

interventions that are irreversible due to learning effects

, and when treatment can't be withdrawn. In this design, behavior is measured across either multiple individuals, behaviors, or settings.

What type of research is multiple baseline design?

A multiple baseline design is used in

medical, psychological, and biological research

. The multiple baseline design was first reported in 1960 as used in basic operant research.

What is a multiple baseline design why is it used distinguish between multiple baseline designs across subjects across behaviors and across situations?

A multiple baseline design is used

to measure the effectiveness of treatment when a behavior changes after the manipulation is introduced

. It is used because multiple conditions rule out the chance of other events that influence behavior occurring in data, displaying the effectiveness of the treatment.

What are the three types of multiple baseline designs?

Three basic types of multiple baseline design are (a)

multiple baseline across different behaviors of the same subject

, (b) multiple baseline across the same behavior of different subjects, and (c) multiple baseline of the same behavior of one subject across different settings.

What is multiple baseline design example?

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 are the disadvantages of a multiple baseline design?

The main disadvantage of the multiple baseline design is

that a high degree of planning is required to produce a successful implementation

. The ABA or Reversal Design demonstrates the effect of the experimental variable by repeatedly introducing and withdrawing the experimental variable.

What is a Nonconcurrent multiple baseline design?

Nonconcurrent multiple baseline designs

stagger the timing of baseline-to-intervention changes across various entities

, but the baselines and intervention phases are not contemporaneous across each of the tiers.

What is the structure of a typical multiple baseline design?

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 is a multiple baseline graph?

Learn to create a Multiple Baseline Design Graph in:

In this design,

behavior is measured across either multiple individuals, behaviors, or settings

. Similar to the reversal design, the multiple baseline starts with the baseline (phase A), then proceeds with the intervention (phase B).

What is the main difference between a multiple baseline and a multiple probe design?

Multiple Baseline Design –

analyzes the effects of an independent variable across multiple behaviors/settings/participants (dependent variable)

without having to withdraw the treatment. Multiple probe design – analyzing a successive approximation or task sequence.

How do you identify a quasi experimental design?

Like a true experiment, a quasi-experimental design aims to establish a cause-and-effect relationship between an independent and dependent variable. However, unlike a true experiment, a quasi-experiment does not rely on random assignment. Instead,

subjects are assigned to groups based on non-random criteria

.

What are the advantages of an ABAB design?

ABAB designs have the benefit of

an additional demonstration of experimental control with the reimplementation of the intervention

. Additionally, many clinicians/educators prefer the ABAB design because the investigation ends with a treatment phase rather than the absence of an intervention.

What is a major advantage of a within subjects design?

The single most important advantage of a within-subjects design is that

you do not have to worry about individual differences confounding your results

because all treatment groups include the exact same partcipants.

What is meant by baseline in a single case design?

Baseline period – In SCD research, the baseline period is similar to

the ‘treatment as usual condition'

in group designs. During the baseline period, the DV is measured until a visibly consistent response pattern is present.
