Applications of a sequential alternating treatment design.

Area of Science:

• Behavioral Science
• Research Methodology
• Applied Behavior Analysis

Background:

• Traditional baseline conditions may be inadequate or impractical in certain clinical settings.
• Existing research designs may not always provide sufficient contrast for treatment evaluation.

Purpose of the Study:

• To propose and describe a novel research design: the sequential alternating treatments design.
• To offer a viable alternative to traditional baseline conditions in behavioral research.
• To enhance the assessment of treatment efficacy under clinical constraints.

Main Methods:

• Combines elements of alternating treatments design and multiple baseline design.
• Involves initial random or counterbalanced implementation of two treatments.
• Sequentially introduces changes in treatments across settings, subjects, or tasks.

Main Results:

• The design allows for assessment of relative treatment effects by comparing data series.
• Sequential application of treatments provides a measure of experimental control, similar to multiple baseline designs.
• The initial alternating treatments phase serves as a contrast condition, akin to a baseline.

Conclusions:

• The sequential alternating treatments design is a flexible and effective methodology for clinical research.
• This design addresses limitations of traditional baseline conditions.
• It is applicable to diverse research areas, including peer training and self-injurious behavior assessment.
