Area of Science:

  • Psychology
  • Psychiatry
  • Substance Abuse Research

Background:

  • The Ego Function Assessment (EFA) is a self-report inventory designed to measure 12 distinct ego function measures.
  • Reliability and stability are crucial for any psychological assessment tool, particularly in clinical settings.
  • Understanding ego functioning is vital in the treatment of substance abuse.

Purpose of the Study:

  • To examine the test-retest reliability and internal consistency of the Ego Function Assessment.
  • To evaluate the stability of the 12 ego function measures over a 2-week period.
  • To explore potential response sets and discuss data in the context of state vs. trait ego functioning.

Main Methods:

  • A cohort of 89 individuals undergoing substance abuse treatment completed the Ego Function Assessment.
  • A subset of 81 participants completed the inventory a second time after a 2-week interval.
  • Interitem consistency was assessed using a hierarchical algorithm, and retest scores evaluated scale stability.

Main Results:

  • The study presents standardization, reliability, and stability data for both original and revised EFA scales.
  • Revised scales demonstrated optimal internal consistency (alphas).
  • Stability data indicate the reliability of the 12 scales over the 2-week retest interval.

Conclusions:

  • The Ego Function Assessment demonstrates acceptable reliability and stability for use in substance abuse populations.
  • The findings support the utility of the EFA as a measure of ego functioning in this clinical group.
  • Further research is warranted to explore state vs. trait aspects of ego functioning as measured by the EFA.
