Recent studies suggest that impulsivity fluctuates over time. It is unclear if state-impulsivity serves as a risk factor of suicidal ideation (SI) at a state level. A sample of 74 psychiatric inpatients with depression (M = 37.6 years, 72% female) and SI completed baseline measurements and an ecological momentary assessment over a 6-day period. Despite considerable within-person variance, state impulsivity was not significantly associated with clinical characteristics (depression, baseline SI, past suicide attempts). Daily variability of passive SI showed a significant prospective association with state impulsivity. Limiting factors are the small sample size and the short observation period.
最近的研究表明，冲动性会随时间波动。目前尚不清楚状态冲动性在状态层面是否作为自杀意念（SI）的一个风险因素。一个由74名患有抑郁症（平均年龄M = 37.6岁，72%为女性）且有自杀意念的精神科住院患者组成的样本完成了基线测量以及为期6天的生态瞬时评估。尽管个体内部存在相当大的差异，但状态冲动性与临床特征（抑郁、基线自杀意念、既往自杀未遂）并无显著关联。被动自杀意念的每日变异性与状态冲动性存在显著的前瞻性关联。研究的局限性在于样本量小以及观察期短。
