Area of Science:

  • Behavioral Science
  • Psychology
  • Educational Research

Background:

  • Single-subject research designs are crucial for evaluating interventions.
  • Synthesizing findings from single-subject studies presents unique challenges.
  • Existing methods for quantitative synthesis require critical evaluation.

Purpose of the Study:

  • To review the literature on quantitative synthesis of single-subject research.
  • To describe and critique procedures for synthesizing single-subject data.
  • To evaluate the application and meaningfulness of synthesis results.

Main Methods:

  • Literature review of quantitative synthesis methods for single-subject research.
  • Description and critique of synthesis procedures.
  • Analysis of results from applied synthesis procedures.

Main Results:

  • Percentage of Nonoverlapping Data (PND) is a justifiable and meaningful synthesis procedure.
  • PND applications across nine studies yielded highly meaningful results.
  • Results from PND are faithful to the original single-subject research reports.

Conclusions:

  • Quantitative synthesis of single-subject research is feasible and valuable.
  • Percentage of Nonoverlapping Data (PND) is a recommended approach.
  • This synthesis method enhances the interpretability and utility of single-subject findings.
