摘要

建立跨分析单元的认知节奏迟缓(SCT)的相关性,并更好地理解如何在精神病理学模型中将 SCT 概念化,这一点非常重要。本研究考察了 SCT 症状与社交和认知压力任务中自动神经系统反应的关系。研究对象是 61 名 8-12 岁的儿童,他们的注意力缺陷/多动障碍(ADHD)症状严重程度各不相同。家长提供了对 SCT 的评分,家长和教师完成了用于创建多动症症状综合指数的测量。对儿童进行了标准化的同伴排斥和不可能完成的拼图任务,在此期间记录了他们的呼吸窦性心律失常(RSA)和皮肤电导水平(SCL)反应性。回归分析表明,SCT 症状与任一任务的 RSA 反应性无关。SCT 症状越严重,SCL 对同伴拒绝的反应越大,两者有明显的相关性。SCT症状的加重与SCL对不可能完成的拼图任务的反应性没有明显关系。在控制多动症症状、内化症状、药物治疗状态或性别的敏感性分析中,研究结果的模式没有改变。这项研究首次证明了SCT症状与交感神经系统反应性有关。这些研究结果表明,SCT症状可能与更大的行为抑制系统激活有关,而反应性可能在社交挑战中尤为明显。

Physiological Correlates of Sluggish Cognitive Tempo in Children: Examining Autonomic Nervous System Reactivity during Social and Cognitive Stressor Tasks.

It is important to establish correlates of sluggish cognitive tempo (SCT) across units of analysis and to better understand how SCT may be conceptualized in models of psychopathology. The current study examined SCT symptoms in relation to automatic nervous system reactivity during social and cognitive stressor tasks. Participants were 61 children ages 8-12 years with a full range of attention-deficit/hyperactivity disorder (ADHD) symptom severity. Parents provided ratings of SCT and parents and teachers completed measures that were used to create composite indices of ADHD symptoms. Children were administered standardized peer rejection and impossible puzzle tasks, during which their respiratory sinus arrhythmia (RSA) and skin conductance level (SCL) reactivity were recorded. Regression analyses indicated that SCT symptoms were unassociated with RSA reactivity to either task. Greater SCT symptoms were significantly associated with greater SCL reactivity to peer rejection. Greater SCT symptoms were not significantly associated with SCL reactivity to the impossible puzzle task. The pattern of findings was unchanged in sensitivity analyses that controlled for ADHD symptoms, internalizing symptoms, medication status, or sex. This study provides the first evidence that SCT symptoms are associated with sympathetic nervous system reactivity. These findings suggest that SCT symptoms may be associated with greater behavioral inhibition system activation, and reactivity may be especially pronounced in social challenges.

期刊介绍: Research on Child and Adolescent Psychopathology brings together the latest innovative research that advances knowledge of psychopathology from infancy through adolescence. The journal publishes studies that have a strong theoretical framework and use a diversity of methods, with an emphasis on empirical studies of the major forms of psychopathology found in childhood disorders (e.g., disruptive behavior disorders, depression, anxiety, and autism spectrum disorder). Studies focus on the epidemiology, etiology, assessment, treatment, prognosis, and developmental course of these forms of psychopathology. Studies highlighting risk and protective factors; the ecology and correlates of children''s emotional, social, and behavior problems; and advances in prevention and treatment are featured. Research on Child and Adolescent Psychopathology is the official journal of the International Society for Research in Child and Adolescent Psychopathology (ISRCAP), a multidisciplinary scientific society.
