The current study explored dynamics of secure state attachment expectations in everyday life in middle childhood, specifically state attachment carry-over and reactivity to experiences of caregiver support in the context of stress. In two independent samples (one community sample, N = 123; one adoption sample, N = 69), children (8–12 years) daily reported on their state attachment for respectively 14 and 7 consecutive days. Additionally, they reported daily on their experiences of distress and subsequent experiences of caregiver support. Results in both samples indicated that secure state attachment on a day-to-day basis is characterized by a significant positive carry-over effect, suggesting that state attachment fluctuations are (partially) self-predictive. In Study 1, experiencing no support following distress significantly related to intraindividual decreases in secure state attachment; in Study 2, experiencing effective support during distress related to intra-individual increases in secure state attachment. Taken together, the current studies provide novel and important insights into how state attachment temporally evolves on a day-to-day basis in middle childhood.

目前的研究探讨了童年中期日常生活中安全状态依恋期望的动态变化，特别是状态依恋的延续和对压力背景下照顾者支持体验的反应。在两个独立样本中（一个社区样本，N = 123；一个收养样本，N= 69），儿童（8-12 岁）每天分别连续 14 天和 7 天报告他们的依恋状态。此外，他们每天报告他们的痛苦经历和随后得到照顾者支持的经历。两个样本的结果表明，日常的安全状态依恋具有显着的积极结转效应，表明状态依恋波动是（部分）自我预测的。在研究 1 中，在与安全状态依恋的个体内减少显着相关的痛苦之后没有得到支持；在研究 2 中，在与安全状态依恋的个体内增加相关的痛苦中获得有效支持。综合起来，
