Acute Effects of Interpersonal Stress on Behavioral Indices of NSSI

 描述（由申请人提供）：非自杀性自伤（NSSI），定义为直接，故意破坏自己的身体组织，没有死亡的意图（1），比曾经认为的更常见;大约14%至35%的大学生（2，3）参与这种行为。此外，NSSI与许多不良结局相关，包括组织损伤/瘢痕形成、人际关系中断和未来的自杀行为（4 - 10）。虽然对NSSI的研究越来越多，但大多数研究仍然使用非实验方法，限制了我们检查NSSI及其相关因素之间因果关系的能力。行为范式的纳入将允许以模仿现实生活行为的方式对NSSI进行实证调查，提供有关NSSI行为和pupilion相关变量的更丰富信息。其中一个有趣的变量是人际压力，它被认为对自我伤害的想法和行为有重大影响。例如，人际关系问题被发现会促使自我伤害的想法（28）和更严重的自我伤害行为（例如，自杀企图; 29 - 31）。然而，很少有实证证据研究人际压力对NSSI的直接影响，以及相关的潜在缺陷，如人际问题解决能力（32）。本研究旨在通过实验研究人际关注的急性消极情绪对自伤行为/态度和人际问题解决的影响。考虑到大学年龄段人群中NSSI的高发病率，拟议研究的参与者将是有和没有近期NSSI病史的大学生。参与者将完成与自我伤害行为相关的结构的诊断评估和自我报告措施。接下来，他们将接受（a）人际消极情绪诱导（B）一般消极情绪诱导或（c）人际中性情绪诱导，之后他们将完成人际问题解决，自我伤害行为和内隐NSSI关联的行为测量。本研究的多组、多方法设计将允许对人际关注的负面情绪对NSSI行为的具体影响进行强有力的评估和比较。因此，这项研究有可能更好地了解急性负面情绪的情绪和行为反应，并可能为现存的自伤理论提供新的见解，并可能有助于指导NSSI的治疗和预防工作。

 DESCRIPTION (provided by applicant): Non-suicidal self-injury (NSSI), defined as the direct, intentional destruction of one's own body tissue without the intent to die (1), is more common than once believed; approximately 14% to 35% of college students (2,3) engage in the behavior. Additionally, NSSI is associated with numerous adverse outcomes, including tissue damage/scarring, disruptions in interpersonal relationships, and future suicidal behavior (4-10). Although research on NSSI is increasing, most studies continue to use non-experimental methods that limit our ability to examine causal relationship between NSSI and its correlates. The inclusion of behavioral paradigms would allow for empirical investigations of NSSI in a way that mimics real-life behavior, providing richer information about NSSI behavior and putatively related variables. One such variable of interest is interpersonal stress, which is thought to have a substantial impact on self-injurious thoughts and behaviors. For example, interpersonal problems have been found to precipitate self-harming thoughts (28) and more severe self-harming behaviors (e.g., suicide attempts; 29-31). There is little empirical evidence, however, examining the immediate impact of interpersonal stress on NSSI, and related potential deficits, such as interpersonal problem solving abilities (32). The proposed study will experimentally examine the effect of interpersonally-focused acute negative mood on self-injurious behavior/attitudes, and interpersonal problem solving. Given the high rate of NSSI among college-aged individuals, the participants of the proposed study will be college students with and without a recent history of NSSI. Participants will complete a diagnostic assessment and self-report measures of constructs related to self-injurious behavior. Following, they will receive either (a) an interpersonal negative mood induction (b) a general negative mood induction or (c) an interpersonal neutral mood induction, after which they will complete behavioral measures of interpersonal problem solving, self-injurious behavior, and implicit NSSI associations. The multi-group, multi-method design of this study will allow for a powerful assessment and comparison of the specific impact of an interpersonally- focused negative mood on NSSI behaviors. Thus, this study has the potential to provide a better understanding of the emotional and behavioral responses to acute negative mood and could provide new insights into extant theories of self-injury and may help guide NSSI treatment and prevention efforts.
