How marital Attachment Styles Impact Dyadic Adjustments： The Mediating Role of Communication Patterns
No full text健康家庭建设政策的出台和离婚率高企的现实提出了研究婚姻关系维系和破裂机制的必要，婚姻是典型的依恋体验过程，沟通在维系婚姻关系，促进家庭健康的过程中扮演着重要的作用。
本文的2个研究分别从个体和夫妻层面研究了依恋风格通过沟通方式影响婚姻关系质量的机制。研究1使用路径分析指出女性要求/男性退缩的沟通方式中介了个体依恋焦虑和依恋回避对自身婚姻关系质量的负向影响，两性的影响机制不存在显著的差异；使用回归混合模型研究个体依恋模式的剖面分类，将女性个体分为安全、普通、冷漠和恐惧四类型，男性分为安全和恐惧两类型，指出恐惧型依恋模式的婚姻关系质量较低，冷漠型又低于恐惧型，表明依恋焦虑可能在高依恋回避情况下保护婚姻关系质量，使用反事实因果效应分解方法发现了要求/退缩型沟通方式在依恋模式对婚姻关系质量影响上的中介作用；使用测量网络分析 指出女性和男性依恋风格-沟通方式-婚姻关系质量相互影响系统中最重要的节点都是沟通方式中的“双方都会把自己的感受告诉对方”，比较了两性网络系统，未发现显著的结构、边权重或节点中心性指标差异。
研究2使用夫妻配对样本和二元响应面回归分析发现了依恋风格对共同婚姻关系质量和对自身和对方和要求/退缩型沟通方式的负向和正向影响，及依恋风格的匹配效应，使用组块变量法指出要求/退缩型沟通方式中介了依恋风格匹配特征对婚姻关系质量的影响；使用回归混合模型和反事实因果效应分解方法研究了夫妻层面依恋模式的剖面分类并研究了要求/退缩型沟通方式的中介作用，发现高依恋焦虑、高依恋回避的恐惧型夫妻的共同婚姻关系质量高于低依恋焦虑、高依恋回避的冷漠型夫妻，指出高回避情境下高焦虑可能是婚姻关系质量的保护因素；使用测量网络分析研究了夫妻依恋风格-沟通方式-婚姻关系质量网络系统 中的重要节点，指出使女方感知的“双方都尝试着讨论解决问题矛盾”对夫妻网络系统全局和男方网络尤其是男方的婚姻关系质量都有最重要的影响。
不同于依恋回避和依恋焦虑都是婚姻关系质量破坏性因素的经典结论，本文发现在高依恋回避存在时，高依恋焦虑可能在个体和夫妻关系层面都对婚姻关系质量存在保护作用；本文采用较新颖的二元响应面回归分析，研究了夫妻依恋回避和依恋焦虑对自身和对方要求/回避型沟通方式和共同婚姻关系质量的负向效应，研究了双方依恋风格一致性的匹配效应；采用共病网络分析方法，更好地拟合了依恋理论中依恋可变性的观点，并得出了精准到显变量层面的沟通方式干预靶点。本文在成人依恋理论发展、方法学创新和实践应用方面都具有一定的价值。</p
Symptom network connectivity in PTSD comorbid with depression in bereaved Chinese parents who have lost their only child
No full textBackground The death of a child is a highly traumatic event for parents and often leads to posttraumatic stress disorder (PTSD) and depression. PTSD and depression are frequently comorbid. However, the patterns of comorbidity at the symptom level among bereaved parents remain unclear. This study aims to identify the symptom network connectivity of PTSD comorbid with depression in bereaved Chinese parents who have lost their only child, known as Shidu parents in Chinese society. Methods Data were obtained from 477 bereaved individuals who had lost an only child. A regularized partial correlation network was used to construct comorbidity networks of PTSD and depression symptoms. A relative importance network was computed to determine directionality among symptoms in the network. Results PTSD symptoms of diminished interest, irritability/anger, reckless/self-destructive behavior, a negative emotional state, the avoidance of reminders, and flashbacks acted as important bridging nodes. The relative importance network analysis show two bidirectional pathways (hypervigilance reversible arrow exaggerated startle response reversible arrow difficulty concentrating reversible arrow sleeping difficulties reversible arrow poor sleep ; irritability/anger reversible arrow reckless/self-destructive behavior reversible arrow could not get going reversible arrow bothered by things), and exaggerated startle response, difficulty keeping mind, hypervigilance, and diminished interest have higher outstrength values with greater influence on a multitude of other symptoms within the comorbidity network. Conclusions The findings highlight the important role of specific symptoms and identified bidirectional pathways underscore the interconnected nature of PTSD and depression symptoms, suggesting that targeting these core or highly influential symptoms may disrupt the broader network and improve therapeutic outcomes
Dysfunctions of Reward Motivation Adaptation in Patients With Schizophrenia
No full textDiminished reward motivation in the wanting or liking dimension constitutes one of the core dysfunctions in patients with schizophrenia (SCZ). However, it remains unclear whether patients with SCZ would dynamically adapt their wanting or liking towards reward in response to a favourable effort-reward ratio and whether such adaptation correlates with their clinical symptoms or functional outcome. In this study, thirty patients with SCZ and 30 healthy controls (HC) were recruited to complete the reward motivation adaptation task (RMAT) based on mental arithmetic effort and manipulating effort-reward ratios. Clinical symptoms were assessed in the clinical group while pleasure experience and social functioning were assessed in all participants. We found that patients with SCZ exhibited less reward wanting and liking than HC in "effort = reward" and "effort < reward" conditions. Neither reward wanting nor liking in patients with SCZ adapted with effort-reward ratio as indicated by significantly smaller coefficients (beta wanting and beta liking) compared with HCs. Besides, SCZ patients' adaptation ability was positively correlated with social functioning in daily life. In conclusion, this study indicates that patients with SCZ not only exhibited reduced reward motivation in favourable conditions but also dysfunctions of reward motivation adaptation, and such deficits could explain poor functional outcome.</p
Work stress and depressive symptoms of employees in the logistics industry: Willingness to communicate and rumination as parallel mediators
No full textTo explore the relationship between work stress and depressive symptoms, as well as the dual mechanisms of willingness to communicate and rumination, we surveyed 520 logistics employees who completed the Work Stress Questionnaire, the Willingness to Communicate Scale, the Rumination Responses Scale, and the Center for Epidemiological Studies Depression Questionnaire-Short Version. The results revealed that work stress was significantly and positively associated with depressive symptoms and rumination, whereas it was significantly and negatively associated with willingness to communicate. Further, willingness to communicate was significantly and negatively associated with depressive symptoms, and rumination was significantly and positively associated with depressive symptoms. Finally, willingness to communicate and rumination acted as parallel mediators between work stress and depressive symptoms. These results have theoretical implications and offer practical references for managers and employees in logistics organizations
The Relationship Between Parent-Child Attachment and Peer Attachment and Depression in College Students: A Moderated Polynomial Regression With Response Surface Analyses
No full textPrevious research has established a strong link between parental attachment and depression in youth. However, the nuances of paternal-maternal attachment congruence and its relationship with depressive symptoms, as well as the roles of gender differences and peer attachment in this context, remain unclear. This study aimed to explore these associations among emerging adults. Attachment and depressive symptoms were assessed in 1564 college students using the Inventory of Parent and Peer Attachment (IPPA) and the Patient Health Questionnaire-9 (PHQ-9), respectively. Polynomial regression and response surface analysis were utilized for data analysis. The results revealed that when paternal and maternal attachment were congruent, students with average-range levels of parental attachment (i.e., scores near the IPPA mean) exhibited the least depressive symptoms. Conversely, greater discrepancies between paternal and maternal attachment were associated with more pronounced depressive symptoms, while this effect was buffered by higher levels of peer attachment. In addition, incongruent paternal and maternal attachments were not significantly associated with depressive symptoms in sons, whereas insecure maternal attachment was more closely related to daughters' depressive symptoms. In conclusion, this study highlights the importance of parental attachment (in)congruence in college students' depressive symptoms and the moderating roles of gender and peer attachment
Coordinated hippocampal-entorhinal representations support human context-dependent spatial navigation
No full textTo execute goal-directed behavior, retrieval of both context and object information is crucial. Despite the ubiquity of such contextual computations in daily navigation, the neural mechanisms underlying this process in humans and its connection to behavior remain largely elusive. Leveraging intracranial electroencephalography (iEEG) recorded from epilepsy patients (N = 31) engaged in a context-dependent spatial navigation task, we uncovered distinct oscillatory patterns in the hippocampus (HC) and entorhinal cortex (EC) that represented context and object information, respectively. Notably, the covariation of these neural representations predicted behavioral performance. Furthermore, both representations were primarily driven by low-frequency oscillations (2-8 Hz). The synchronization of low-frequency oscillations between HC and EC was associated with enhanced object representations in the EC. These findings highlight the importance of low-frequency neural dynamics in mediating both local representations and interregional interactions within the hippocampal-entorhinal circuit during context-dependent spatial navigation.</p
High compliance and reduced online gaming time among Chinese adolescents after the 2021 gaming policy: Effects across all gamers, not just heavy users
No full textGovernment policies have been proposed to mitigate excessive online gaming among adolescents, yet empirical evaluations of their effectiveness remain limited. Following China's 2021 online gaming policy, the strictest such regulation to date, we examined the compliance rate and alternative behaviors among heavy adolescent gamers. Several methodological concerns have been raised, including the omission of the 2019 policy, the narrow focus on heavy gamers, and ambiguities in key definitions. In this response, we address these concerns by clarifying the policy's independence, expanding the analysis to all adolescent participants, and incorporating pre- and post-policy gaming time as an additional measure of policy impact. Results from a broader sample (N = 2,715, mean age = 10.84) revealed a high compliance rate (93.6%) and a significant decrease in daily gaming time following the policy (60.12 vs. 43.52 min per day, p < 0.001). This reported gaming time may include offline or single-player gameplay. These findings support the conclusion that the 2021 policy significantly reduced adolescents' gaming time and achieved high compliance rates, though self-reported data may include offline gameplay and that historical policy context should be acknowledged in interpretation. Moreover, its longer-term effects on psychological well-being and physical health warrant further investigation
Electrophysiological Mechanisms Underlying Cognitive Control Impairment in Methamphetamine‑Dependent Patients
No full text甲基苯丙胺依赖（methamphetamine use disorder，MAUD）具有高复吸率与高社会危害性，越来越多的循证研究提示复吸冲动与认知控制缺陷之间存在因果关系。然而，以往研究多聚焦单一指标（如 SSRT），忽视了认知控制的双维结构，也鲜少在同一任务框架中同步追踪时序-空间多层级的神经机制。本研究在双重控制模型（Dual Mechanisms of Control, DMC）指导下，从行为、事件相关电位（ERP）与多频段脑网络三层面，系统解析 MAUD 患者主动性与反应性控制的分离性损伤特征，为精准干预提供证据。共招募强制戒毒男性 MAUD 患者 72 例与健康对照（HC）32 例。所有受试者完成改进版条件停止信号任务（cSST）， 并同步记录 64 导联 EEG。研究一：独立样本 t 检验比较准备成本（PC）与停止信号反应时（SSRT）的组间差异，偏相关检验其与药物渴求量表（OCDUS） 各维度的关系。研究二：在 170-270 ms 提取 Fz/F3-N200，在 280-450 ms 提取 Cz-P300，比较振幅、潜伏期差异，并构建 ERP-行为-临床的三维相关矩阵。研 究三：基于相位同步构建 Theta（4-8 Hz）、Alpha（8-12 Hz）、Beta（13-30 Hz） 网络，计算全局效率、局部效率、聚类系数，采用非参数置换检验评估组间差异，并控制当前戒断月数的协变量效应。结果：① 行为学：MAUD 组 PC 显著低于HC（t=2.809,p=0.008,d=0.63），SSRT 组间差异不显著，但 SSRT 与 OCDUS 总 分显著正相关（r=0.36,p=0.001）。② ERP：MAUD 组 Go 试次 N200 振幅下降 23%（p<0.001），其幅值与 PC 正相关（r=0.32）；P300 振幅下降 18%（p=0.048）， 潜伏期缩短 27 ms。P300 振幅与 SSRT（r=−0.35）及渴求频率（r=−0.30）显著 相关。③ 网络：Theta 频段 MAUD 组全局效率、局部效率与聚类系数较 HC 分 别升高 14%、17% 与 19%（均 p<0.01），并与 PC 呈负相关（r≈−0.30）；Alpha、 Beta 频段亦见不同程度超同步化，且与 OCDUS 多维度呈正相关。协变量分析显示戒断时长不改变主要结论。</p
The Relationship between Gifted Children’s Understanding of Others’ Emotions and Creative Self-Efficacy： The Chain Mediation of Cognitive Reappraisal and Cognitive Strategy Use
No full text超常儿童的创造性自我效能感是其发展创造力的重要基础。本研究以178名普通班的超常儿童为研究对象，基于多视角模型，采用自陈量表探讨理解他人情绪对创造性自我效能感的影响，并进一步探讨认知重评和认知策略使用在二者之间的链式中介作用。通过构建结构方程模型，采用Bootstrap重复抽样5000次的方法检验中介效应，同时控制年级及性别。结果表明：（1）创造性自我效能感、理解他人情绪、认知重评和认知策略使用两两之间显著正相关，且理解他人情绪能显著正向预测创造性自我效能感；（2）认知重评与认知策略使用在理解他人情绪与创造性自我效能感中起显著中介作用，存在三条中介路径：认知重评的单独中介作用、认知策略使用的单独中介作用和认知重评与认知策略使用的链式中介作用。该结果启示学校应引导超常儿童理解他人情绪，并鼓励超常儿童将认知重评与认知策略使用相结合，从而增强创造性自我效能感。</p
