Social and individual risk factors for suicide ideation among Chinese children and adolescents: A multilevel analysis

The objective of this study was to investigate the prevalence and predictors of suicide ideation among primary, middle and high school students. We used multilevel modelling to investigate suicide ideation among 12,733 Chinese children and adolescents aged 9–18 years from wide range of areas across China. Approximately, 32.09% of children and adolescents reported suicide ideation, with females were more likely to report suicide ideation than males (38.09% vs. 29.95%). Our results showed that the risk factors in primary school students were different from middle and high school student groups, whereas significant risk factors for middle and high school students were similar. The city's standard of living as indicated by the Engel coefficient and the city's divorce rate were positively associated with the prevalence of suicide ideation; in contrast, the school's pupil‐to‐teacher ratio was negatively correlated with elevated suicide ideation. Significant risk factors for suicide ideation included study anxiety, self‐accusation tendency, impulsive tendency, terror tendency and physical symptoms. These results have important implications for the prevention of suicide, suggesting that both contextual (city‐level) and compositional (individual‐level) factors could be important targets for prevention and intervention for children and adolescents at risk of suicide ideation.     

Neuropsychological outcomes of pediatric demyelinating diseases: a review

Immune-mediated central nervous system (CNS) demyelinating diseases impact various areas of the brain, optic nerves, and/or spinal cord and can result in a wide range of neurologic symptoms including adverse cognitive outcomes. Neuropsychological outcomes in adult multiple sclerosis (MS) are well documented, while literature on such outcomes in pediatric cohorts is more limited. Furthermore, literature on neuropsychological outcomes in pediatric acute disseminated encephalomyelitis (ADEM), neuromyelitis optica (NMO), and transverse myelitis (TM) is even more limited. This paper is the first to review what is known about neuropsychological outcomes associated with immune-mediated CNS demyelinating diseases, with a focus on pediatric MS, ADEM, NMO, and TM. Additionally, this review illuminates the need to clarify differences in neuropsychological sequelae between conditions, characterize longitudinal cognitive outcomes, and investigate neuropsychological outcomes in relation to clinical variables (e.g., age of onset, disease duration, number of relapses) and psychosocial variables (e.g., fatigue, emotional problems, behavioral functioning) to better understand neuropsychological outcomes associated with these conditions.     

青少年抑郁的快感缺失的神经机制研究

抑郁逐渐低龄化使得青少年抑郁备受关注。快感缺失,作为抑郁的一种核心临床症状,已成为抑郁最具前景的内表型之一。然而,青少年抑郁的快感缺失的神经机制迄今仍不清楚。本研究首先汇总两种神经机制模型即三元模型和社会挫折模型;其次,在多种奖励加工如金钱奖励、努力动机奖励、未来奖励和社会奖励条件下,概述青少年抑郁的快感缺失的神经机制前沿进展。未来可以深入探索努力动机奖励和未来奖励在预测青少年抑郁中的作用,加强研究青春期阶段与性别是如何交互影响早期抑郁快感缺失,将无创伤电磁刺激应用于青少年抑郁干预中,进一步澄清青少年抑郁的快感缺失的神经发展机制。     

中国青少年互联网心理与行为研究及展望

本文回顾了近十年来中国青少年互联网心理与行为的研究成果,从研究主题的角度进行了聚类分析,并与国外青少年互联网心理与行为研究进行了对比。发现中国青少年互联网心理与行为研究主要聚焦于网络成瘾方面,同时也在网络欺负、网络亲社会行为、网络自我表露等领域有较为丰富的研究成果。现有研究存在研究领域相对狭窄、研究内容深度不足、研究方法较为单一等问题。结合青少年互联网使用特点和时代发展与变迁,本文从大数据、新媒体、电子竞技三个方面展望了未来中国青少年互联网心理与行为研究的方向,对互联网时代下的心理学研究具有理论和实践的启发意义。     

Emotion Regulation in Adolescent Well-Being and Positive Education

Emotion regulation (ER) becomes increasingly important across adolescent development, and promotes psychological flexibility, resilience and well-being in youth. Positive education programs (PEPs) combine academic training with positive psychology interventions (PPIs) to increase well-being and reduce mental ill-health. Despite considerable overlap between PPIs and ER models, the role and relevance of ER to PEPs remains unclear. This review aimed to evaluate the relationship of ER to PEPs targeting adolescents. First, to evaluate the relationship of ER to domains of well-being targeted by school-based PPIs. Second, to examine whether school-based PPIs can improve adolescents’ ER capacity. Third, to evaluate the role of ER in well-being outcomes of PEPs. Results support the relevance of ER to domains of well-being outlined by the revised PERMA model, including positive emotions, engagement, relationships, meaning, and health. ER can influence the degree to which students benefit from PEP participation. It remains to be determined whether ER capacity is improved as a result of exposure to positive education programs. Findings are limited by the small and heterogeneous group of interventions examined, and the use of inconsistent ER measures. Further research of the role of ER in positive education may contribute to greater understanding of the mechanisms underlying their effectiveness and further promote the psychological well-being of adolescents.     

Electrophysiological measures reveal the role of anterior cingulate cortex in learning from unreliable feedback

Although a growing number of studies have investigated the neural mechanisms of reinforcement learning, it remains unclear how the brain responds to feedback that is unreliable. A recent theory proposes that the reward positivity (RewP) component of the event-related brain potential (ERP) and frontal midline theta (FMT) power reflect separate feedback-related processing functions of anterior cingulate cortex (ACC). In the present study, the electroencephalogram (EEG) was recorded from participants as they engaged in a time estimation task in which feedback reliability was manipulated across conditions. After each response, they received a cue that indicated that the following feedback stimulus was 100%, 75%, or 50% reliable. The results showed that participants’ time estimates adjusted linearly according to the feedback reliability. Moreover, presentation of the cue indicating 100% reliability elicited a larger RewP-like ERP component than the other cues did, and feedback presentation elicited a RewP of approximately equal amplitude for all of the three reliability conditions. By contrast, FMT power elicited by negative feedback decreased linearly from the 100% condition to 75% and 50% condition, and only FMT power predicted behavioral adjustments on the following trials. In addition, an analysis of Beta power and cross-frequency coupling (CFC) of Beta power with FMT phase suggested that Beta-FMT communication modulated motor areas for the purpose of adjusting behavior. We interpreted these findings in terms of the hierarchical reinforcement learning account of ACC, in which the RewP and FMT are proposed to reflect reward processing and control functions of ACC, respectively.     

身体动作趋势对道德词空间-效价一致性效应的影响

在经典的空间—效价一致性范式的基础上,控制向上或向下看的动作趋向及幅度大小,探讨身体动作趋势对空间—效价一致性效应的影响。实验一分别在屏幕上方视野或下方视野进行词汇道德效价的判断。结果表明,在屏幕的上方视野和屏幕的下方视野不道德词汇都出现了空间—效价一致性效应,而道德词汇只在下方视野出现了一致性效应。实验二将注视点居于屏幕中央,改变词汇上下位置之间垂直距离的大小。发现在小间距条件下出现了显著的一致性效应,但是在大间距条件下一致性效应消失。综合两个实验表明,道德词的空间—效价一致性效应同时受到概念隐喻和极性相关的影响,当空间极性不明显时,概念隐喻的影响较大,而空间位置极性较明显时,空间位置极性会掩盖概念隐喻的作用。

Evidence for a Higher-Order ESEM Structure of ADHD in a Sample of Chinese Children

Exploratory structural equation modeling (ESEM) solutions have been proposed to represent the factor structures of attention-deficit/hyperactivity disorder (ADHD) in recent literature, yet no studies have assessed those structures in Chinese children. The primary aim of this study was to comprehensively examine the factor structures of the Chinese version of the ADHD Rating Scale-IV (ADHD RS-IV): Home Version. Data on 458 Chinese children aged 3–8 years (boys: 246; 54%) were used to test and compare eleven factor models: confirmatory factor analysis (CFA) models (one-factor, two-factor and three-factor), second-order CFA model, bifactor CFA models (two and three specific factors), ESEM models (two-factor and three-factor), second-order ESEM model, and bifactor ESEM models (two and three specific factors). The results showed that, overall, ESEM models displayed better fit than CFA models. Specifically, the second-order ESEM model with three first-order factors best represented of the ADHD factor structure in our sample. In addition, measurement invariance testing results showed that scalar invariance was established across gender, age and informant groups. Implications for future research are discussed.
