Abstract
OBJECTIVE
To examine the moderating effect of trait affective lability on the relationship between past suicidal behavior and future nonsuicidal self-injury (NSSI).
METHOD
A total of 127 adult females diagnosed with bulimia nervosa took part in this study. We hypothesized that individuals with greater levels of self-reported trait affective lability and a greater number of past suicide attempts would engage in a greater number of NSSI episodes over the course of 2 weeks than would individuals lacking elevations in one or both of those variables, controlling for average level of negative affect and affective lability as measured through ecological momentary assessment (EMA).
RESULTS
The two-way interaction of trait affective lability and past suicidal behavior predicted participants' number of NSSI episodes during the course of the study.
DISCUSSION
Interaction of self-reported trait affective lability and past suicidal behavior may exhibit clinical utility in the prediction of patients' imminent risk of engaging in NSSI.
摘要
目的
考察特质情感不稳定性对既往自杀行为与未来非自杀性自伤（NSSI）之间关系的调节作用。
方法
共有 127 名被诊断为神经性贪食症的成年女性参与了这项研究。我们假设，与那些在一个或两个变量上没有升高的个体相比，报告有更高水平特质情感不稳定性和更多既往自杀尝试的个体，在 2 周的时间内会经历更多的 NSSI 发作，这是通过通过生态瞬时评估（EMA）测量的平均负性情绪和情感不稳定性来控制的。
结果
特质情感不稳定性和既往自杀行为的双向交互作用预测了参与者在研究过程中 NSSI 发作的次数。
讨论
报告的特质情感不稳定性和既往自杀行为的相互作用，可能在预测患者即将发生 NSSI 的风险方面具有临床意义。
