Ego function assessment of nonclinical individuals

Ego Function Assessment was adapted into a self-report inventory yielding 12 operationalized function measures. 426 respondents from a stratified sample completed the inventory. In addition, 42 respondents completed the inventory twice within a 20-day period. A hierarchical algorithm was used to revise the 12 scales to maximize internal consistencies. Their stabilities were assessed by analyzing the retest scores. Standardization, reliability, and stability data are presented for the original and revised scales. Results show adequate reliability, suggesting that the tool may be useful to measure ego functioning in nonclinical populations.
