Negative affective states and impulsivity have been found to be closely associated with non-suicidal self-injury (NSSI), but how negative affect contributes to impulsivity in NSSI adolescents and the role of perceived social support remain unclear.
In Study 1, the Barratt Impulsiveness Scale (BIS-11) was administered on 225 NSSI adolescents and 225 healthy volunteers to determine the characteristics of impulsivity in the patients. In Study 2, 102 of the patients were randomly selected to further complete the Zung Self-rating Anxiety Scale (SAS), Zung Self-rating Depression Scale (SDS), and Multidimensional Scale of Perceived Social Support (MSPSS) to clarify the relationships between negative affect, perceived social support, and impulsivity in these patients.
In Study 1, NSSI adolescents scored higher than volunteers on almost all factors of BIS-11 except for Cognitive Instability. In Study 2, Support from significant others mediated the association between SAS and BIS-11 Self-control. Moreover, Support from significant others and family moderated the prediction of SAS score on their BIS-11 Cognitive Complexity.
Compared to healthy adolescents, NSSI individuals were more impulsive, while perceived support from family and significant others prevented the anxious NSSI adolescents from lower cognitive complexity. Therefore, more social support should be available to NSSI adolescents with high anxiety to reduce their risk of self-harm due to high impulsivity.
消极情绪状态和冲动性已被发现与非自杀性自伤（NSSI）密切相关，但消极情绪如何导致NSSI青少年的冲动性以及感知社会支持的作用仍不清楚。
在研究1中，对225名NSSI青少年和225名健康志愿者进行了巴拉特冲动性量表（BIS-11）测试，以确定患者的冲动性特征。在研究2中，从患者中随机选取102名进一步完成zung自评焦虑量表（SAS）、zung自评抑郁量表（SDS）和感知社会支持多维量表（MSPSS），以阐明这些患者中消极情绪、感知社会支持和冲动性之间的关系。
在研究1中，NSSI青少年在BIS-11的几乎所有因子上的得分均高于志愿者，但认知不稳定性因子除外。在研究2中，来自重要他人的支持介导了SAS与BIS-11自我控制之间的关联。此外，来自重要他人和家庭的支持调节了SAS分数对其BIS-11认知复杂性的预测。
与健康青少年相比，NSSI个体更冲动，而来自家庭和重要他人的感知支持可防止焦虑的NSSI青少年出现较低的认知复杂性。因此，应向高焦虑的NSSI青少年提供更多社会支持，以降低其因高冲动性而导致自我伤害的风险。
