Key result
Error-related negativity (ERN) demonstrated moderate test-retest reliability (0.56 to 0.67) over a 1.5 to 2.5 year period, supporting its utility as a trait-like neural measure.
Observational (n=26)
Effect estimate: 0.56 to 0.67
The error-related negativity (ERN) demonstrates moderate test-retest reliability over a 1.5 to 2.5 year period, supporting its utility as a trait-like neural measure.
May support ERN as stable research marker; leaves open clinical predictive value or practice change in cardiology.
The error-related negativity (ERN) is a negative deflection in the event-related potential (ERP) following an erroneous response and is thought to reflect activity of the anterior cingulate cortex. There is accumulating evidence that the component has trait-like properties; prior evidence further suggests test-retest reliability estimates ranging from .40 to .82 over a period of 2 to 6 weeks. The present study examined temporal stability over a longer time period. Error-related brain activity was recorded from 26 subjects during an arrow version of the flankers task on two occasions separated by 1.5 to 2.5 years. Depending on the scoring method, test-retest reliability of the ERN ranged from .56 to .67. These data are consistent with previous suggestions that the ERN is a moderately stable, trait-like neural measure.

Weinberg et al. (2011) reported an observational. Test-retest interval was evaluated on Test-retest reliability of the error-related negativity (ERN) (0.56 to 0.67). Error-related negativity (ERN) demonstrated moderate test-retest reliability (0.56 to 0.67) over a 1.5 to 2.5 year period, supporting its utility as a trait-like neural measure.
