Abstract

Current theoretical frameworks posit that engagement in non-suicidal self-injury (NSSI) is due to an inability to regulate one’s emotions. In turn, mindfulness-based interventions have been shown to enhance emotion regulatory processes in those who engage in NSSI. Objective. The purpose of the present study was to determine whether a brief mindfulness activity was differentially effective at increasing state mindfulness and decreasing stress following a stress induction task in university students with versus without a history of NSSI engagement. Method. The sample consisted of two groups of participants who identified as women: participants with a history of NSSI engagement (NSSI; n = 57; M_age=20.09, SD = 2.05) and participants without (no-NSSI; n = 87; M_age=20.22, SD = 1.94). All participants were asked to complete pre-intervention measures of state mindfulness and stress and were randomly assigned to either a mindfulness activity (body scan) or control task condition. Following the completion of their respective activities, a Stroop stress induction task was conducted and participants completed post-intervention measures of state mindfulness and stress. Results. Two 3-way mixed ANOVAs (Time X NSSI status X Condition) were conducted and revealed significant time by condition interactions for both state mindfulness, Wilk’s Λ = .93, F(1, 140) = 10.70, p = .001, η_p² = .07, and stress, Wilk’s Λ = .97, F(1, 140) = 4.21, p = .04, η_p² = .03. As such, both groups (NSSI/no-NSSI) demonstrated similar increases in state mindfulness and decreases in stress in response to the brief mindfulness activity following the stress induction. Implications for future research and practice will be discussed.

• HIGHLIGHTS

• The brief mindfulness activity effectively increased state mindfulness.

• The brief mindfulness activity effectively decreased stress.

• Benefits were experienced similarly among both groups (NSSI/no-NSSI).

摘要

目前的理论框架认为，参与非自杀性自伤（NSSI）是由于无法调节自己的情绪。反过来，基于正念的干预已被证明可以增强参与 NSSI 的人的情绪调节过程。客观的。本研究的目的是确定在有和没有 NSSI 参与历史的大学生中，在压力诱导任务后，简短的正念活动是否在增加状态正念和减轻压力方面有不同的效果。方法。样本由两组被确定为女性的参与者组成：有 NSSI 参与历史的参与者（NSSI；n  =  57；M_年龄=20.09，SD = 2.05）和没有（无 NSSI；n  = 87；M_年龄=20.22，SD  = 1.94）的参与者。所有参与者都被要求完成状态正念和压力的干预前测量，并被随机分配到正念活动（身体扫描）或控制任务条件。在完成各自的活动后，进行了 Stroop 压力诱导任务，参与者完成了状态正念和压力的干预后测量。结果。进行了两个 3 路混合 ANOVA（时间 X NSSI 状态 X 条件），并揭示了两种状态正念的条件交互作用的显着时间，Wilk's Λ = .93, F (1, 140) = 10.70, p = .001, η _p ²= .07，应力，Wilk 的 Λ = .97，F (1, 140) = 4.21，p = .04，η _p ² = .03。因此，两组（NSSI/no-NSSI）都表现出类似的状态正念增加和压力减少，以响应压力诱导后的短暂正念活动。将讨论对未来研究和实践的影响。

• 强调

• 简短的正念活动有效地增加了状态正念。

• 简短的正念活动有效地减轻了压力。

• 两组的获益相似（NSSI/no-NSSI）。
