What does multiple baseline design mean?
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 are the types of multiple baseline design?
There are three types of multiple base- line designs. These include the multiple baseline across behaviors, subjects or par- ticipants, and settings (Cooper, Heron, & Heward, 1987; Gay, 1987; Gay & Airasian, 2000; Hersen & Barlow, 1984; Kazdin & Kopel, 1975; McReynold & Keams, 1983; Neuman & McCormick, 1995).
What is a main disadvantage to 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 an advantage of the multiple baseline design?
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baseline design is useful for interventions that are irreversible due to learning effects, and when treatment can’t be withdrawn.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 can be said about the internal validity of a multiple baseline design?
Thus, the multiple-baseline design represents a simple AB design, but it is replicated more than once to establish the reliability of the effect. The internal validity of such a design is ensured by the multiple replications of the intervention delivered across subjects, settings, or behaviors.
What are the limitations of delayed multiple baseline design?
delayed multiple baseline design initial baseline and intervention followed by subsequent baselines added in delayed fashion; analytic tactic where reversal no longer possible/wanted, limited resources, new behavior/setting/subject becomes available limitations of delayed multiple baseline design (3) – having to wait too long to modify behaviors
What are the three types of multiple baseline designs?
The three major types of multiple baseline designs are multiple baseline across behaviors, settings, and subjects The researcher takes repeated measures of baseline performance concurrently on two or more baselines
Why are multiple baseline design used in behavior analysis?
Multiple Baseline Design Most widely used in Applied Behavior Analysis Multiple Baseline Design Can analyze effects of IV w/o having to withdraw treatment; highly flexible Multiple Baseline Design Can analyze effects of IV across multiple: Settings, Subjects, Behaviors Reason to use Multiple Baseline Design instead of reversal (ABAB design)
Why do we use non concurrent multiple baseline?
Hypothetical data obtained through use of a non concurrent multiple baseline design. It is possible that, due to the ambiguity of the descriptions of traditional multiple-baselines, some researchers have been using the nonconcurrent design in the past.
