DESCRIPTION (provided by applicant): Goals: My research has dealt primarily with the behavioral mechanisms underlying chronic SIB among individuals with developmental disorders. A more complete understanding of the pathophysiology of SIB will require integrating our rich understanding of pain neurobiology and stress psychobiology with our emerging understanding of the role of early experience on multiple pain and stress-sensitive physiological systems. Research: During my R29 funding period, I extended the opioid model of SIB in line with clinical features suggestive of altered pain processing, formed collaborative relations, and began developing the necessary expertise allowing me to seek funding to test an integrative pain and stress model of SIB in adults. The purpose of the funded R01 is to compare socially and nonsocially-mediated SIB adult cases on a set of behavioral and biological measures related to sensory function, stress physiology, and pain behavior. Career Plan: The career development plan uses a translational research training framework as an organizing set of principles to guide research and training goals specific to new developments in neuroscience and behavioral genetics, integrating the wider research program of developmental psychopathology, and expanding the self- injury research agenda to embrace gene-environmental interplay and improve our understanding of individual vulnerability. Preliminary work and collaborative relations are described to support the need for release time to enhance my training and research into these related areas. The plan emphasizes the need to extend self- injury research to issues germane to pediatric and neurological research (i.e., pain regulation, high risk populations), and to include other systems important in the regulation of pain (i.e., peripheral and central transmission mechanisms), stress (i.e., the HPA axis), and the autonomic nervous system (i.e., fronto-limbic and autonomic circuitry). Specifically, I want to gain the expertise to test the following three preliminary hypotheses. First, there will be differences in hypothalamic-pituitary-adrenal (HPA) axis activity (cortisol) and sensory function (detection thresholds) in children with severe neurological impairment and self-injury compared with matched controls without self-injury (between group analyses). Second: the frequency and temporal sequencing of self-injury will be correlated with HPA axis activity and sensory function (within group analyses). Third, the relation between HPA axis activity, sensory function, and SIB will change over time such that the degree of dysregulation in the former predicts increasing severity in the latter (prospective analysis). Institution and Environment Commitment: The Department of Educational Psychology and the University of Minnesota are committed to this award and provide rich resources for my career development.

描述(由申请人提供)：目标：我的研究主要涉及患有发育障碍的个体慢性SIB的行为机制。要更全面地了解SIB的病理生理学，需要将我们对疼痛、神经生物学和应激心理生物学的丰富理解与我们对早期经验在多种疼痛和应激敏感生理系统中的作用的新认识结合起来。研究：在我的R29资助期间，我根据SIB疼痛处理过程改变的临床特征扩展了SIB的阿片类药物模型，形成了合作关系，并开始开发必要的专业知识，使我能够寻求资金在成人中测试SIB疼痛和应激综合模型。资助的R01的目的是比较社会和非社会中介的SIB成人病例在一系列与感觉功能、应激生理和疼痛行为相关的行为和生物测量上的差异。职业发展计划：职业发展计划使用转化性研究培训框架作为一套组织原则，以指导针对神经科学和行为遗传学新发展的研究和培训目标，整合更广泛的发展精神病理学研究计划，并扩大自我伤害研究议程，以拥抱基因与环境的相互作用，并提高我们对个体脆弱性的理解。介绍了初步工作和合作关系，以支持释放时间的需要，以加强我在这些相关领域的培训和研究。该计划强调，需要将自我伤害研究扩展到与儿科和神经学研究(即疼痛调节、高危人群)密切相关的问题，并包括在调节疼痛(即外周和中枢传递机制)、应激(即HPA轴)和自主神经系统(即额叶-边缘和自主神经回路)中至关重要的其他系统。具体地说，我想获得专业知识来检验以下三个初步假设。首先，有严重神经损伤和自我损伤的儿童与没有自我损伤的对照组相比，下丘脑-垂体-肾上腺(HPA)轴活动(皮质醇)和感觉功能(检测阈值)将有差异(组间分析)。第二：自我伤害的频率和时间顺序将与HPA轴活动和感觉功能相关(在组内分析)。第三，HPA轴活动、感觉功能和SIB之间的关系将随着时间的推移而变化，因此前者的失调程度预示着后者的严重程度(前瞻性分析)。机构和环境承诺：教育心理学系和明尼苏达大学致力于这一奖项，并为我的职业发展提供了丰富的资源。
