对奖励的异常神经反应越来越被认为是青春期新出现的精神病理的生物学关联。然而，这种观点假设这些反应具有良好的心理测量特性——尤其是内部一致性——这一假设很少得到检验。我们计算了8-14岁女性（n=177）对金钱得失反馈的事件相关电位（ERPs）和血氧水平依赖（BOLD）反应的内部一致性（即半溢出信度）。比较了腹侧纹状体和内侧/外侧前额皮质内erp（即反馈负性）和BOLD反应在获得、损失、差异分数（增益-损失）和剩余分数（增益控制损失）方面的内部一致性。进行了适度分析，以调查内部一致性是否因年龄而异。各区域对增益和损失反馈的ERP和BOLD反应具有较高的内部一致性（Spearman Brown系数(SB)≥0.70）。然而，当考虑差值和残差分数时，反应的内部一致性较低（SBs≤0.50），特别是基于减法的分数的内部一致性较低（SB≤0.36）。年龄并不是分裂关系的显著调节因子，表明童年晚期到青春期早期的内部一致性相似。在同一受试者中，观察到ERP和fMRI对收益和损失反应的测量具有高度的内部一致性，其不随年龄而变化。此外，即使在实验的前半部分，出色的心理测量特性也很明显。尽管基于回归的方法优于基于减法的差异分数，但差异分数的特点是内部一致性较低。
Abnormal neural response to reward is increasingly thought to function as a biological correlate of emerging psychopathology during adolescence. However, this view assumes such responses have good psychometric properties—especially internal consistency—an assumption that is rarely tested. Internal consistency (i.e., spilt-half reliability) was calculated for event-related potentials (ERPs) and Blood Oxygen Level Dependent (BOLD) responses to monetary gain and loss feedback from the same sample of 8–14 year-old females (n=177). Internal consistency for ERPs (i.e. feedback negativity) and BOLD responses within the ventral striatum and medial/lateral prefrontal cortex to gain, loss, difference scores (gain-loss), and residual scores (gain controlling for loss) were compared. Moderation analyses were conducted to investigate whether internal consistency differed by age. ERP and BOLD responses to gain and loss feedback showed high internal consistency in all regions (Spearman Brown Coefficients (SB) ≥ 0.70). When considering difference and residual scores, however, responses showed lower internal consistency (SBs ≤ 0.50), with particularly low internal consistency for subtraction-based scores (SB ≤ 0.36). Age was not a significant moderator of split-half relationships, indicating similar internal consistency across late childhood to early adolescence. Within the same subjects, high internal consistency was observed for both ERP and fMRI measures of response to gains and losses, which did not vary as a function of age. Moreover, excellent psychometric properties were evident even within the first half of the experiment. Difference scores were characterized by lower internal consistency, although regression-based approaches outperformed subtraction-based difference scores.
