Research to elucidate early alterations of higher cognitive processes in adolescents with BPD is rare. This study investigated differences in dual-task performance in adolescents with BPD during stress and non-stress conditions. The study sample comprised 30 female adolescents with BPD and 34 healthy controls. The impact of stress on dual-task performance was measured using a standardized stressor. Self-reports of distress and measures of heart rate (HR) were obtained to measure stress reactivity. There were no group differences in task performance. Under stress conditions, the performance on the auditory task decreased in both groups but without significant group differences. Healthy controls showed an increase of mean HR after stress induction compared to no change in the BPD group. The finding of attenuated HR response to acute stress in adolescent patients with BPD may contradict current theories that the affective hyperresponsivity in BPD is based on a biologically determined mechanism.
旨在阐明边缘型人格障碍（BPD）青少年高级认知过程早期改变的研究很少。本研究调查了BPD青少年在应激和非应激条件下执行双重任务的差异。研究样本包括30名患有BPD的女性青少年和34名健康对照者。使用标准化应激源测量应激对双重任务表现的影响。获取痛苦的自我报告和心率（HR）测量值以评估应激反应性。两组在任务表现上没有差异。在应激条件下，两组的听觉任务表现均下降，但无显著组间差异。与BPD组无变化相比，健康对照者在应激诱导后平均心率增加。BPD青少年患者对急性应激的HR反应减弱这一发现可能与当前认为BPD情感反应过度基于生物学决定机制的理论相矛盾。
