Interpreting data from experimental functional analysis (EFA) can yield varied results. This study found poor test-retest reliability for EFA methods in individuals with intellectual disabilities, impacting clinical practice.

Area of Science:

  • Behavioral Psychology
  • Intellectual Disabilities Research
  • Applied Behavior Analysis

Background:

  • Experimental functional analysis (EFA) is a key assessment tool for understanding challenging behaviors.
  • Reliability and validity of EFA interpretation methods are crucial for effective clinical application.
  • Previous methods for interpreting EFA data exist, but their consistency requires further investigation.

Purpose of the Study:

  • To investigate the convergent validity of an experimental (analog) functional analysis.
  • To compare three distinct data interpretation methods for EFA, including two established and one novel approach (criterion Z).
  • To assess the test-retest reliability of these interpretation methods over multiple time intervals.

Main Methods:

  • Collected EFA data from 27 individuals with intellectual disabilities exhibiting challenging behaviors.

  • Analyzed data using three different interpretation methods: two published and the criterion Z method.
  • Calculated test-retest reliability for all methods at 2 weeks, 1 month, and 3 months.

    • Main Results:

    • Significant differences were observed in the results obtained from the three EFA data interpretation methods.
    • The study revealed poor test-retest reliability across all examined interpretation methods.
    • Agreement between the different interpretation approaches was limited.

    Conclusions:

    • The choice of interpretation method for EFA data can substantially influence outcomes.
    • The poor test-retest reliability of current EFA interpretation methods raises concerns for clinical practice.
    • Further research is needed to develop more reliable and valid methods for EFA data interpretation.
