心理病理学网络理论、方法与挑战

对于精神障碍这一概念的理解, 传统DSM-ICD分类诊断系统和研究领域标准RDoC均基于潜变量视角, 认为精神障碍的症状由其潜在共同原因所致。这2种观点都忽略了症状间的相互作用。不同于分类和维度视角, Borsboom在2008年对精神障碍的概念化提出了的全新视角——心理病理学网络理论。此理论的核心观点是症状之间的动态因果关系构成了精神障碍。基于心理病理学网络理论的网络分析方法, 主要以结合EBIC的glasso算法估计症状间的偏相关网络, 并通过网络中节点中心性与网络连接性等指标, 来考查精神障碍症状的不同特性。近几年来, 研究者发现心理病理学网络分析方法在对症状间因果关系的推断、核心症状的识别和网络结构的可靠性与可重复性方面仍面临一些挑战。这些挑战为心理病理学网络理论与方法指明了未来可能的发展方向。     

反馈相关负波与成瘾

反馈相关负波(feedback-related negativity, FRN)是反馈加工诱发的脑电成分, 体现了个体对奖赏的敏感性。成瘾分为物质成瘾和行为成瘾, 两类个体的反馈加工都呈现病理性模式。相对于普通反馈物(如金钱), 物质成瘾个体在加工成瘾物质时诱发的FRN波幅显著增大; 在与非成瘾被试的对照研究中, 物质成瘾者加工金钱反馈时的FRN也表现出与成瘾相关的异常模式; 在行为成瘾个体中亦观察到与物质成瘾个体类似的FRN失调现象。但以往多数研究中对成瘾类型的区分还不够详细, 未来研究应进一步考虑成瘾不同亚型的特点; 且成瘾个体往往伴随其他精神障碍(如抑郁、焦虑), 将来的研究要区分共病因素的影响, 揭示成瘾独特的奖赏加工机制问题。     

孤独感和手机成瘾的关系:一项元分析

孤独感与手机成瘾均是当下生活中较为常见的现象, 诸多研究基于不同的理论视角探讨了两者间的内在联系, 但研究结果却存在很大分歧。为明确两者之间的整体关系, 以及产生分歧的原因, 对检索后获得的121项研究(124个效应值)使用随机效应模型进行了元分析。结果发现:孤独感与手机成瘾存在中等程度的正相关(r = 0.25, 95% CI = [0.23, 0.27]); 两者的相关性受被试年龄群体的调节, 成年人群体中的相关系数显著高于青少年群体, 但两者的相关性不受性别、孤独感和手机成瘾测量工具的影响。结果表明孤独感与手机成瘾关系密切, 支持了补偿性网络使用理论和自我调节缺陷模型。未来应加强纵向研究或实验研究进一步揭示孤独感与手机成瘾的作用方向。     

基于门户理论视角下的青少年物质成瘾

青少年物质成瘾行为受到普遍的关注, 成瘾物质滥用的机制一直是学者们探讨和研究的焦点。门户理论提出青少年发展成严重药物滥用者的过程存在顺序和阶段特征, 合法物质的使用会增加发展为非法药物使用的风险, 这种顺序效应得到了实证研究的支持。本研究在综述以往研究的基础上发现, 基于门户理论视角下青少年药物使用存在顺序效应, 但以往研究仍然存在一些不足, 例如药物使用顺序的不固定, 解释范围有限, 内在机制不清楚以及各种影响因素缺乏整合等。未来可以扩展研究对象和范围, 以深入研究顺序效应的内在机制。     

多文本阅读理解中的认识论信念:实证进展及理论争议

多文本阅读理解,是将不同来源和内容的多文本信息整合为统一心理表征的认知过程。研究者对于多维度认识论信念与多文本阅读理解之间的关联进行梳理。除知识来源外,其余认识论信念维度促进多文本信息的整合。基于文档模型的理论框架,认识论信念各维度对于整合心智模型与跨文本模型的影响,中介效应与调节效应并存。未来的研究可以采用眼动追踪技术和出声思维法等实时的研究方法,对于相关理论模型进行确证和完善。     

基于技术接受模型的青少年网络游戏成瘾机制研究

本研究以技术接受模型(TAM)为理论框架, 通过对380名中学生的问卷调查考察了青少年网络游戏成瘾的影响因素及其机制。结果发现:(1)有用感、易用感、品质感知、游戏体验和态度与网络游戏成瘾显著正相关;(2)品质感知和游戏体验通过态度的部分中介作用对网络游戏成瘾产生间接影响, 同时对网络游戏成瘾有直接效应;有用感和易用感通过态度的完全中介作用对网络游戏成瘾产生间接影响, 对网络游戏成瘾没有直接效应。本研究结果表明, 品质感知、有用感、易用感和游戏体验对青少年网络游戏成瘾具有重要影响, 态度是其中的重要中介变量。     

青少年网络成瘾的预防与干预研究

网络成瘾障碍(Internet Addiction Disorder,IAD)已成为影响青少年身心健康和正常学业表现的重要因素。针对青少年网络成瘾的心理预防与干预研究已开展逾十年,分析与总结显示,已有研究采用个体、团体等不同干预模式,采用认知行为、动机激发等不同咨询与治疗理论,对青少年网络成瘾行为的干预进行了大量探索;其中以团体干预模式及认知行为疗法为主导,并呈现多模式多理论相融合的趋势。借鉴已有研究的成果与不足,我们采用家庭治疗、认知行为、动机激发等多种咨询与治疗理论,结合心理需求网络满足优势等网络成瘾理论,形成了个体-家庭-学校的多水平预防与干预方案,并得到了实证研究的检验。今后的研究应进一步考虑青少年网络成瘾的生理因素,将生物-心理-社会三方面相结合形成系统性的网络成瘾预防与干预模式。     

社会信息加工领域中的情境模型理论

自Wyer和Srull把情境模型理论引入社会信息加工领域以来,情境模型理论成了社会信息加工研究的热点,其自身结构和加工机制也得到研究者的不断完善。该文简要介绍了情境模型理论的内容、结构及其基本假设。即情境模型代表人们在社会信息加工过程中形成的关于具体事件和情节的知识,并且通常在社会信息的理解过程中自动建立。这种模式一旦建立,就为理解新信息及作出相应的判断提供基础。情境模型包括三种基本信息:时空框架、实体集合及实体之间的各种相互关系。认为人们在理解信息的过程中至少需要建构5个维度,即:(1)空间,(2)时间,(3)实体,(4)因果,(5)目的。在此基础上,文章讨论了情境模型理论的未来研究方向。     

个体冲动性对物质滥用与成瘾的影响及脑机制

冲动性是一多维的概念,一般指个体缺乏足够预见性或对自身的行为结果缺乏考虑和判断。个体冲动性和物质滥用与成瘾之间存在双重关系,即个体特质冲动性是物质滥用与成瘾的重要危险因素,而滥用成瘾性物质又会进一步损害个体的冲动控制功能。本文将论述个体冲动性和物质滥用与成瘾之间的相关性及冲动性增加潜在的神经机制。了解个体的冲动特质和物质滥用与成瘾者冲动性的改变,研究物质滥用与成瘾者冲动障碍的神经生物学机制,不仅有助于我们揭示物质滥用与成瘾的发生、发展,以及脱毒后复发的脑机制,而且有助于我们探索药物疗法以外的行为干预手段。     

社会比较和社会评价的背景效应——来自联合评估视角的启示

决策领域存在一个经典的联合评估的偏好反转现象(又称评估模式效应),其解释力最强的广义可评估性理论(general evaluability theory, GET)强调了评估模式(即背景信息是否存在)的作用。社会认知领域也存在社会比较和社会评价的背景效应,其著名的包含排除模型(Inclusion/Exclusion Model, IEM)也强调背景信息的作用,尤其是目标-背景相似性的作用。因此,背景效应可以类比于评估模式效应,也可以理解为一种“偏好”(上行同化和下行对比)及其“反转”(上行对比和下行同化)现象。基于从联合评估这一新的视角对背景效应进行的解释和拓展,未来研究应该关注背景效应的测量标准、影响因素之间的交互作用、跨维度作用及其实践应用等方面,以促进对背景效应的深化理解和两个领域的理论融合和实践结合。     

Interpretive Phenomenological Analysis of the Spiritual Characteristics of Recovery Experiences in the Context of the Brain Disease Model of Addiction

Spirituality persists as a mechanism of behavior change for addiction recovery. The aim of this project was to carefully attend to how those in recovery construct meaning of their experience of addiction, regardless of the addiction treatment modality or ideological framework. Participant accounts reflected the increased public interest in and research funding based on the brain disease model of addiction (BDMA). The qualitative study used interpretive phenomenological analysis to investigate the experiences of six adults (age range from 24 to 72) with at least three years of sustained recovery from substance use disorders. In-depth key informant interviews tracked their construction of their experiences and their understanding of addiction. Participants who entered recovery after 2010 sought to integrate BDMA-related constructs into their understanding of addiction and recovery. Addiction recovery narratives featuring BDMA-related constructs integrated neuroscience-related ideas with spirituality-related constructs rather than completely replacing the latter. Notable innovations and paradoxical tensions were found within participant accounts. Such features echo the insights on secularity of Harvard philosopher Charles Taylor, particularly his notion of the “buffered self,” which offers a theoretical framework for understanding these shifts in meaning-making. For persons entering recovery in the twenty-first century, the brain disease model of addiction carries more explanatory authority than it does for previous generations, despite the lack of agreement across addiction-related neuroscientific findings. As a model, it engenders more mechanistic, agential, brain-centered (“buffered”) senses of self, ostensibly making it less compatible with spiritual understandings of addiction than other medical models of addiction. However, this study’s findings indicate that those in recovery are likely to devise complex narratives of the etiology of addiction that combine elements from various models.     

Neurorobiology and evidence-based biological treatments for substance abuse disorders

Behavioral patterns of addiction include compulsive drug-seeking, persistent abuse of substances despite the often dire consequences on social functioning and physical health, and the high probability of relapse even after prolonged drug-free periods. The recent focus on the biological basis of addiction has provided evidence to support the hypothesis that behavioral manifestations for addiction are influenced by biological factors, and biological factors often produce behavioral changes that can further increase risk. The current understanding of the role of the dopaminergic, glutamatergic, Upsilon-aminobutyric acidergic, and opioid receptor systems in the pathophysiology of addiction as well as the clinical implications of these systems for new and emerging treatments will be discussed. This article will also review the pharmacologic agents used in the treatment of substance abuse disorders and presents evidence-based data for their safety, efficacy, and feasibility of use in different patient populations.     

物质成瘾及其戒除:基于反转学习的视角

物质成瘾与反转学习损伤密切相关,成瘾者往往不能灵活地适应变化的刺激—结果的联结,这可能进一步加剧成瘾者的物质使用。近年来研究发现,物质成瘾者的反转学习相关的腹外侧前额和背外侧前额等脑区激活异常,这些异常与成瘾者的冲动性和强迫性有关。此外,个体的反转学习能力对其成瘾行为具有一定预测性。今后应增加对不同类型物质成瘾者的反转学习脑机制及物质相关线索对成瘾者反转学习影响的研究,并且进一步探讨成瘾者的冲动性和强迫性对其反转学习的调节及个体反转学习能力对其成瘾行为的预测。     

“Is it me or should my friends take the credit?” The role of social networks and social identity in recovery from addiction

This study explored the role of social network and social identity factors in recovery from addiction. The sample consisted of 537 individuals who completed a survey about their experiences of recovery. Results indicated that the transition from addiction to recovery was characterized by an increase in social connectedness and changes in social network composition coupled with the emergence of a “recovery” identity. These factors accounted for 14% of the variance in quality of life when controlling for known predictors, accounting for a greater proportion of variance than substance use variables. Results suggest that recovery from addiction can be understood as a socially mediated transition characterized by social network and social identity change, which drive broader improvements in quality of life.     

空间导航的脑网络基础和调控机制

空间导航在生活中时刻发生,空间能力衰退是阿尔兹海默症的重要早期表现。早期关于空间导航神经机制的研究主要关注单个脑区的特异性功能,但这些脑区如何交互以整合不同模态的信息支持复杂导航行为尚不清楚。脑成像技术、脑网络建模方法和神经调控手段的发展,为在脑网络水平理解人类空间导航的认知神经机制提供了重要研究手段。本研究试图融合空间导航认知神经机制研究的最新进展,借助脑网络建模、大数据分析、微电流刺激等前沿研究手段,研究空间导航脑网络的关键拓扑属性特征(如模块化、核心节点等),探寻该功能特异性神经网络的重要影响因素和调控机制,并构建空间导航的脑网络理论模型。研究成果将有利于理解人类复杂导航行为的脑网络基础,为阿尔兹海默症等相关认知障碍脑疾病的筛查和诊断提供重要参考。     

成瘾的生物心理社会模型

成瘾的易感因素和维持因素是一个复杂的因果网络系统．有三种研究取向。生物学取向综述了成瘾的脑机制和遗传基因观。心理学模式主要介绍成瘾人格的研究现状,以及成瘾的强化观。社会因素则阐述了创伤性事件、父母及同伴压力对成瘾的影响。本文支持三个因素的相互作用导致了成瘾行为的发生,以期从成瘾易感和维持因素的探析上为生物心理社会模型(BPS)提供依据。     

A Christian Faith-Based Recovery Theory: Understanding God as Sponsor

This article reports the development of a substantive theory to explain an evangelical Christian-based process of recovery from addiction. Faith-based, 12-step, mutual aid programs can improve drug abstinence by offering: (a) an intervention option alone and/or in conjunction with secular programs and (b) an opportunity for religious involvement. Although literature on religion, spirituality, and addiction is voluminous, traditional 12-step programs fail to explain the mechanism that underpins the process of Christian-based recovery (CR). This pilot study used grounded theory to explore and describe the essence of recovery of 10 former crack cocaine-addicted persons voluntarily enrolled in a CR program. Data were collected from in-depth interviews during 4?months of 2008. Audiotapes were transcribed verbatim, and the constant comparative method was used to analyze data resulting in the basic social process theory, understanding God as sponsor. The theory was determined through writing theoretical memos that generated key elements that allow persons to recover: acknowledging God-centered crises, communicating with God, and planning for the future. Findings from this preliminary study identifies important factors that can help persons in recovery to sustain sobriety and program administrators to benefit from theory that guides the development of evidence-based addiction interventions.     

Women’s Perspectives Related to Occupational Performance Following Participation in Substance Use Recovery Programs

Very little research has examined how substance abuse programs affect occupational performance. The progression of addiction and its etiology for women are still under-reported. This study aimed to explore perceived effects of substance use and participation in peer-based programs on women’s occupational performance. Qualitative semi-structured interviews were completed with seven women. Four themes were identified: (1) substance use did not markedly inhibit participation in daily life; (2) recovery was supported by replacing substance related occupations with non-substance related occupations; (3) perceived value of shared perspectives and experiences with others; and (4) the embracing of new perspectives as part of recovery.     

Addiction,the addict,and career: Considerations for the employment counselor

Employment counselors have been resistant to working with persons in recovery from addiction except under the strictest of criteria. This article examines the relationship between this resistance and the concepts of addiction and addict. Following this is an examination of substance abuse recovery and practical suggestions on incorporating recovery knowledge into career counseling. The goals of the article are twofold: (a) to present a framework that highlights the necessity of employment counseling for the recovery process from substance misuse and (b) to affirm that many employment counselors have the skills needed to assist clients who have been labeled as addicts.
