错误处理经常使用错误相关负性（ERN）进行检查，ERN是额叶中央部位发生错误后发生的负向事件相关电位，并被建议作为神经生物标志物，可能有助于表征焦虑风险的轨迹。虽然 ERN 已被证明在成人中具有出色的心理测量特性，但很少有研究检查 ERN 在儿童和青少年中的心理测量特性。当前的研究检查了儿童和青少年样本中 ERN 的 2 年重测可靠性，以及使用侧翼和进行/不进行任务的 ERN 的收敛有效性。结果表明，ERN 在 2 年和跨任务中都是可靠且稳定的。然而，结果还表明，使用侧翼任务获得的内部一致性大于使用 go/no-go 任务获得的内部一致性。
Error processing is frequently examined using the error-related negativity (ERN), a negative-going event-related potential occurring after the commission of an error at frontal-central sites, and has been suggested as a neural biomarker that may be useful in characterizing trajectories of risk for anxiety. While the ERN has been shown to have excellent psychometric properties in adults, few studies have examined psychometric properties of the ERN in children and adolescents. The current study examined the 2-year test-retest reliability of the ERN in a sample of children and adolescents, and the convergent validity of the ERN using a flanker and go/no-go task. Results suggest that the ERN is both reliable and stable across 2 years and across tasks. However, results also indicate that the internal consistency obtained using the flanker task is greater than the internal consistency obtained using the go/no-go task.
