Spontaneous mind-wandering has been theorized to increase susceptibility for rumination, contributing to risk for major depressive disorder (MDD). Clarifying whether-and under what circumstances-mind-wandering leads to rumination could inform the development of targeted interventions to reduce risk for ruminative sequelae. Using intensively sampled data in 44 young adults with remitted MDD and 38 healthy volunteers with 1,558 total observations collected from 2018 to 2022, we conducted multilevel models to investigate temporal relationships between mind-wandering and rumination. Contextual factors (e.g., intensity of negative affect; momentary impulsivity) and individual factors (e.g., MDD history) were examined as moderators of these relationships. Mind-wandering predicted increased rumination, whereas rumination did not predict increased mind-wandering. When individuals experienced greater negative affect or acted more impulsively compared to their usual levels, they showed a stronger relationship between mind-wandering and subsequent rumination. Depression history did not significantly moderate temporal relationships between mind-wandering and rumination. Spontaneous mind-wandering may transition into rumination, particularly during moments when people experience more negative affect or impulsivity compared to usual. Delivering interventions in these moments could reduce risk for ruminative sequelae. The tendency to ruminate in response to mind-wandering is suggested to be consistent regardless of depression history, suggesting the transdiagnostic and dimensional nature of rumination as a possible consequence of mind-wandering. Future work is needed to determine whether these associations are generalizable across the lifespan. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
有理论认为，自发的思维游荡会增加陷入沉思的易感性，进而导致重度抑郁症（MDD）的风险。阐明思维游荡是否以及在何种情况下会导致沉思，可为制定有针对性的干预措施提供依据，以降低沉思后遗症的风险。我们对44名缓解期MDD的年轻成年人和38名健康志愿者进行了密集抽样，收集了2018年至2022年的1558次观察数据，通过多层次模型研究思维游荡与沉思之间的时间关系。将情境因素（如负面影响强度；瞬间冲动性）和个体因素（如MDD病史）作为这些关系的调节因素进行检验。思维游荡预示着沉思会增加，而沉思并不能预示思维游荡会增加。当个体与平时相比经历更大的负面影响或表现得更冲动时，他们在思维游荡和随后的沉思之间表现出更强的关系。抑郁病史并未显著调节思维游荡与沉思之间的时间关系。自发的思维游荡可能会转变为沉思，尤其是在人们比平时经历更多负面影响或冲动的时刻。在这些时刻进行干预可以降低沉思后遗症的风险。无论抑郁病史如何，因思维游荡而陷入沉思的倾向似乎是一致的，这表明沉思作为思维游荡可能的后果具有跨诊断和维度性。未来需要开展研究，以确定这些关联是否在整个生命周期中都具有普遍性。（PsycInfo数据库记录（c）2024美国心理学会，保留所有权利）
