Using multilevel structural equation modeling, the authors examined within- and between-person predictors of daily impulsivity, with a particular focus on testing a cascade model of affect and daily stress in a 100-day daily diary study of 101 psychiatric patients with personality disorder diagnoses. On average (i.e., fixed effect), within-person increases in daily stress were associated with increased daily impulsivity, both independently and as accounted for by positive associations with increased negative and positive affect. Higher Personality Inventory for DSM-5 (PID-5) Impulsivity scores were associated with amplified within-person links between impulsivity and daily stress and negative affect, but not the links between daily stress and either positive or negative affect. The results of this cascade model are consistent with the hypothesized links between daily affect and stress and daily impulsivity while providing further evidence for the validity of the PID-5 Impulsivity scale and its ability to predict daily impulsivity above and beyond fluctuations in affect and stress.

日常生活中的冲动、影响和压力：检查紧迫性的级联模型。

使用多层次结构方程模型，作者检查了日常冲动的人内和人之间的预测因素，特别关注在对 101 名患有人格障碍诊断的精神病患者的 100 天每日日记研究中测试情感和日常压力的级联模型. 平均而言（即固定效应），个人日常压力的增加与日常冲动性的增加有关，这两者是独立的，也可以通过与负面和正面影响增加的正相关来解释。DSM-5 (PID-5) 的较高人格量表与冲动性与日常压力和负面影响之间的放大的人内联系相关，但与日常压力与正面或负面影响之间的联系无关。
