Summary

Evaluating units of analysis in behavior analytic research is crucial. A new method, combining percentage correct with competent performance coding and a task analysis grid, meets all four criteria for appropriate measurement.

Area of Science:

Behavior Analysis
Research Methodology

Background:

Task-analytic research in behavior analysis often uses

Purpose of the Study:

To develop and discuss criteria for evaluating units of analysis in task-analytic research.
To propose and evaluate alternative units of analysis.
To identify the most appropriate unit of analysis for behavior analytic research.

Main Methods:

Developed four criteria for evaluating units of analysis.
Evaluated six potential units of analysis, including the commonly used "percentage correct."
Proposed and assessed five alternative units of analysis.

Main Results:

The commonly used "percentage correct" metric met only one of the four established criteria.
Five alternative units of analysis were evaluated.
Only "percentage correct with competent performance coded and a task analysis grid" met all four criteria.

Conclusions:

The "percentage correct" metric is insufficient for rigorous task-analytic research.
A comprehensive approach combining performance coding and a task analysis grid offers a more appropriate unit of analysis.
This enhanced metric improves the evaluation of behavior analytic interventions.
