目的：本研究的目的是探讨是否赤字的情绪调节表现为相对缺乏一致性的主观报告的情绪和自主活动时，面对压力。研究方法：采用多伦多述情障碍量表修订版对830名大学生进行了与述情障碍相关的情绪调节缺陷筛查。那些符合下限标准和其他入选标准的人组成了实验组，并在年龄，性别和种族上与对照组相匹配。最终的样本量为94名学生（每组47名），提出了实验压力任务（Stroop任务和会话任务）的平衡顺序，而自主活动数据（心率和皮肤电导）和主观报告的负面影响不断收集在基线，压力暴露，恢复期。数据进行了分析，以确定自主和主观措施之间的一致性的相对差异。结果如下：数据表明，在整个基线，应激源暴露和恢复期，情绪调节缺陷的参与者报告的主观负面影响始终高于那些没有这种缺陷的人。然而，两组的自主活动在各个阶段几乎保持相同。自主和主观情绪测量之间的一致性组差异的显式测试也部分支持主观过度觉醒的证据。结论：情绪调节的缺陷，在那些具有高水平的述情特质，似乎表现为慢性升高的主观负面影响相对于自主活动，无论环境的要求。这些研究结果的理论和临床意义进行了讨论。(C)2007年爱思唯尔公司All rights reserved.
Objective: The aim of this study was to examine whether deficits in emotion regulation manifest as a relative lack of congruence between subjective reports of emotion and autonomic activity when confronted with stressors. Methods: A pool of 830 university students was screened using the Toronto Alexithymia Scale-Revised for deficits in emotion regulation associated with alexithymia. Those meeting a criterion floor cutoff and other inclusion criteria composed the experimental group and were matched on age, gender, and race to those in the control group. A final sample size of 94 students (47 in each group) was presented with experimental stressor tasks (the Stroop task and a conversation task) in counterbalanced order while autonomic activity data (heart rate and skin conductance) and subjective reports of negative affect were continuously collected during baseline, stressor exposure, and recovery periods. Data were analyzed to determine relative differences in congruence between the autonomic and subjective measures. Results: Data suggested that participants high in emotion regulation deficits reported consistently higher subjective negative affect relative to those without such deficits throughout baseline, stressor exposure, and recovery periods. However, autonomic activity remained nearly identical in both groups across phases. Explicit tests of group differences in congruence between autonomic and subjective emotion measures also partly supported evidence of subjective hyperarousal. Conclusions: Deficits in emotion regulation, as evidenced in those with high levels of the alexithymic trait, appear to manifest as chronically elevated subjective negative affect relative to autonomic activity regardless of the level of environmental demands. Theoretical and clinical implications of these findings are discussed. (C) 2007 Elsevier Inc. All rights reserved.
