Bullying victimization confers the risk for developing various mental disorders, but studies investigating candidate mechanisms remain scarce, especially in the realm of youth mental health. Elevated stress sensitivity may constitute a mechanism linking bullying victimization and mental health problems. In the current study, we aimed to investigate whether exposure to bullying victimization amplifies stress sensitivity in youth's daily life. The Experience Sampling Method (ESM) was used to measure stress sensitivity [i.e. the association of momentary stress with (i) negative affect and (ii) psychotic experiences] in 42 help-seeking youths (service users), 17 siblings, and 40 comparison subjects (mean age 15 years). Before ESM assessments, bullying victimization at school as well as various psychopathological domains (i.e. depression, anxiety, psychosis) were assessed. Service users exposed to high levels of overall (primary hypotheses) as well as specific types (secondary hypotheses; physical and indirect, but not verbal) of bullying victimization experienced more intense negative affect and psychotic experiences in response to stress compared to those with low exposure levels (all p < 0.05), whereas, in contrast, controls showed either less intense negative affect or no marked differences in stress sensitivity by exposure levels. In siblings, a less consistent pattern of findings was observed. Findings suggest that stress sensitivity may constitute a potential risk and resilience mechanism linking bullying victimization and youth mental health. Interventions that directly target individuals' reactivity to stress by providing treatment components in real-life using mHealth tools may be a promising novel therapeutic approach.

寻求帮助的年轻人中的欺凌行为和压力敏感性：一项经验抽样研究的结果。

欺凌受害会增加患上各种精神障碍的风险，但是研究候选机制的研究仍然很少，尤其是在青少年心理健康领域。压力敏感性的升高可能构成了将欺凌行为与心理健康问题联系起来的一种机制。在当前的研究中，我们旨在调查暴露于欺凌行为的受害者是否会放大年轻人日常生活中的压力敏感性。经验抽样方法（ESM）用于测量42位寻求帮助的年轻人（服务使用者），17个兄弟姐妹和40个比较对象的压力敏感性（即，瞬时压力与（i）负面影响和（ii）精神病经历的关系）科目（平均年龄15岁）。在进行ESM评估之前，在学校欺凌受害人以及各种心理病理学领域（例如抑郁症，焦虑症，精神病）。与低暴露者相比，暴露于高水平的总体（主要假设）以及特定类型（次要假设；物理和间接但非言语但非言语）的服务使用者遭受更大的负面影响和精神病体验水平（所有p <0.05），而对照则显示出较低的负面影响，或者暴露水平对压力敏感性没有显着差异。在兄弟姐妹中，观察到的模式不一致。研究结果表明，压力敏感性可能构成将欺凌行为与青年心理健康联系起来的潜在风险和应变机制。直接针对个人的干预措施
