Systematic Review of Descriptions and Justifications Provided for Single-Case Quantification Techniques

Area of Science:

• Behavioral Science
• Research Methodology

Background:

• Single-case designs are crucial in behavioral research.
• Numerous quantification techniques exist for analyzing single-case data.
• Choosing and justifying these techniques can be challenging for researchers.

Purpose of the Study:

• To systematically review quantification techniques used in single-case designs.
• To examine the quality of descriptions and justifications provided for these techniques.
• To enhance the credibility and replicability of single-case research.

Main Methods:

• Systematic literature review of 218 articles.
• Analysis of 290 instances of quantification technique application.
• Examination of provided descriptions and justifications for chosen techniques.

Main Results:

• Non-overlap indices are frequently used quantification techniques.
• Descriptions and justifications for technique selection were often vague or subjective.
• Inconsistent reporting hinders the evaluation of quantification technique appropriateness.

Conclusions:

• Single-case researchers should use objective and appropriate descriptions and justifications for quantification techniques.
• Complementing visual analysis with well-justified quantification is recommended.
• Utilizing guiding tools for technique selection can improve reporting standards.
