Differences in how impulsivity is conceptualized, along with a myopic focus on impulsivity's relationship with historical suicidal behaviors, have resulted in limited implications made from prior research regarding impulsivity and suicidal thoughts and behaviors. The current study investigated the indirect effect facets of impulsivity may have on suicidal ideation, specifically, through thwarted interpersonal needs.
Participants were = 424 undergraduate students who completed a cross-sectional survey. Participants completed the Urgency, Premeditation, Perseverance, Sensation Seeking, Impulsive Behavior Scale (UPPS), the Adult Suicide Ideation Questionnaire (ASIQ), and the Interpersonal Needs Questionnaire (INQ). Parallel mediation models were run to examine the relation between facets of impulsivity, perceived burdensomeness, thwarted belongingness, and suicidal ideation.
Thwarted belonginess and perceived burdensomeness significantly accounted for the variance in the relation between negative urgency and suicidal ideation. Neither thwarted belongingness nor perceived burdensomeness significantly explained variance in the relation between (lack of) premeditation and suicidal ideation. Conversely, perceived burdensomeness and thwarted belonginess significantly explained the inverse relation between sensation seeking and suicidal ideation (i.e., greater sensation seeking was related to lower perceived burdensomeness and thwarted belongingness and in turn lower suicidal ideation).
Negative urgency, in particular, is related to suicidal ideation through thwarted interpersonal needs. Future research should continue to differentiate between various types of impulsivity and its relationship with both suicidal ideation and behaviors utilizing both cross-sectional and ambulatory assessments of these constructs.HIGHLIGHTSNegative urgency is related to suicidal ideation.Negative urgency is related to thwarted interpersonal needs.Thwarted interpersonal needs partially explain the relation between negative urgency and suicidal ideation.
由于对冲动的概念理解存在差异，以及过于关注冲动与历史自杀行为的关系，先前关于冲动与自杀意念和行为的研究仅得出了有限的结论。本研究通过受阻碍的人际需求，考察了冲动的间接影响因素在自杀意念中的作用。
参与者为 424 名本科生，他们完成了一项横断面调查。参与者完成了紧迫感、前计划性、毅力、感觉寻求、冲动行为量表（UPPS）、成人自杀意念问卷（ASIQ）和人际需求问卷（INQ）。平行中介模型用于检验冲动的各个方面、感知负担、归属感受挫与自杀意念之间的关系。
归属感受挫和感知负担显著解释了负性冲动与自杀意念之间关系的差异。前计划性与自杀意念之间的关系既没有归属感受挫，也没有感知负担来显著解释。相反，感知负担和归属感受挫显著解释了感觉寻求与自杀意念之间的反比关系（即，更强的感觉寻求与更低的感知负担和归属感受挫以及更低的自杀意念相关）。
特别是负性冲动，通过受阻碍的人际需求与自杀意念相关。未来的研究应继续区分不同类型的冲动及其与自杀意念和行为的关系，同时利用这些构念的横断面和动态评估。
负性冲动与自杀意念有关。负性冲动与人际需求受挫有关。人际需求受挫部分解释了负性冲动与自杀意念之间的关系。
