有研究表明，抑郁高危青少年在修复自己的悲伤情绪方面存在问题。鉴于交感唤醒在情感的体验和调节中都有牵连，非典型的唤醒模式可能是导致情绪修复问题的因素之一。在目前的研究中，我们测量了从未抑郁的年轻人在悲伤情绪诱导和指导情绪修复期间抑郁的高风险(n=56)和低风险(n=667)的交感唤醒。交感觉醒以皮肤电导水平(SCL)和心脏射血前期(PEP)为指标；情绪修复结果以自评情感为指标。高危青少年在悲伤诱导期间表现出SCL增加，这种情况在情绪修复期间持续；低风险青少年仅在情绪修复期间表现出SCL增加。PEP缩短只有在高危青少年中才明显，而且只有在情绪修复期间才明显。此外，情绪诱导过程中PEP的缩短预示着低风险组较不成功的情绪修复，但在高风险组中则不然。研究结果表明：(A)易患抑郁症的青少年在对情绪刺激的交感反应模式上与对照组同龄人不同，这可能会削弱他们缓解悲伤的能力；(B)交感活动的不同子系统(SCL与PEP)的激活模式与抑郁风险状态有关。
Youths at high risk for depression have been shown to have problems in repairing their own sad mood. Given that sympathetic arousal has been implicated both in the experience and regulation of affect, an atypical pattern of arousal may be one of the factors that contribute to mood repair problems. In the current study, we measured sympathetic arousal of never‐depressed youths at high (n= 56) and low (n= 67) familial risk for depression during sad mood induction and instructed mood repair. Sympathetic arousal was indexed by skin conductance level (SCL) and cardiac pre‐ejection period (PEP); mood repair outcome was indexed by self‐rated affect. High‐risk youths demonstrated increased SCL during sadness induction, which persisted during mood repair; low‐risk youths evidenced increased SCL only during mood repair. Shortened PEP was evident only among high‐risk youths and only during mood repair. Furthermore, shortened PEP during mood induction predicted less successful mood repair in the low‐risk but not in the high‐risk group. The findings suggest that: (a) depression‐prone youths differ from control peers in patterns of sympathetic responses to emotional stimuli, which may impair their ability to relieve sadness, and (b) activation patterns differ across subsystems (SCL vs. PEP) of sympathetic activity, in conjunction with depression risk status.
