背景:非自杀性自我伤害(NSSI)的著名理论提出,行为的特征是放大的情绪反应。然而,关于自我伤害的人在情感挑战中的反应知之甚少。
方法:我们测量了主观和生理反应(心率,心率变异性,和皮肤电反应)在过去一年的NSSI(n=51)和在静息基线期间没有终生NSSI(n=50)的年轻人中,应力诱导,和压力后休息阶段。参与者报告了他们在应激后阶段自发使用认知重新评估和表达抑制的程度。两周后,样本的一个子集(n=42)报告了他们在实验室期间的记忆感觉。
结果:尽管NSSI组报告的情绪失调明显高于对照组,两组都表现出相似的主观和心理反应,和恢复,情感挑战。两组在急性应激后使用了相似程度的重新评估和抑制调节策略,后来以类似的方式记住了情感挑战。
结论:在NSSI组中,过去一年的自我伤害往往是罕见和零星的。只有43.6%的样本参与了评估情绪挑战记忆的后续调查。
结论:研究结果表明,情绪在NSSI中的作用比突出的理论所能解释的要复杂得多,提出了关于NSSI情绪性质的实质性问题。需要更全面地了解情绪在NSSI中的作用,以告知干预策略,以更好地支持自我伤害的人。
BACKGROUND: Prominent theories of nonsuicidal self-injury (NSSI) propose that the behaviour is characterised by amplified emotional responses. However, little is known about how people who self-injure respond during emotional challenge.
METHODS: We measured subjective and physiological responding (heart rate, heart rate variability, and electrodermal responding) among young adults with past-year NSSI (n = 51) and those with no lifetime NSSI (n = 50) during a resting baseline, a stress induction, and a post-stress resting phase. Participants reported the extent to which they spontaneously used cognitive reappraisal and expressive suppression during the post-stress phase. Two weeks later, a subset of the sample (n = 42) reported how they remembered feeling during the laboratory session.
RESULTS: Although the NSSI group reported considerably greater emotion dysregulation than Controls, both groups showed similar subjective and psychological reactivity to, and recovery from, emotional challenge. Both groups used reappraisal and suppression regulation strategies following acute stress to a similar extent, and later came to remember the emotional challenge in a similar manner.
CONCLUSIONS: Within the NSSI group, past-year self-injury tended to be infrequent and sporadic. Only 43.6% of the sample participated in the follow-up survey assessing memory of emotional challenge.
CONCLUSIONS: Findings demonstrate that the role of emotion in NSSI is more complex than prominent theories can account for, raising substantial questions regarding the nature of emotion in NSSI. A more comprehensive understanding of the role of emotion in NSSI is needed to inform intervention strategies to better support people who self-injure.
