ECOLOGICAL MOMENTARY ASSESSMENT OF ANOREXIA NERVOSA

这个子项目是许多研究子项目中的一个 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 子项目说明。 神经性厌食症（AN）是一种严重的，通常难以治疗的精神疾病，具有多种医疗并发症和高死亡率。 尽管与AN相关的显著的医学和心理社会并发症，这种疾病的病因和维持的概念模型是有限的。 目前的研究将开发和测试一种基于人格特征、瞬时情绪状态和认知以及生活事件预测AN症状的维持模型。 我们正在利用一种评估策略，每天多次测量认知，行为和感兴趣的情绪，以便对AN中的思想，感受和行为进行严格和精细的检查。 为了最大限度地减少由于回顾性回忆延迟导致的评估错误，使用电子自我监测系统（生态瞬时评估; EMA）对感兴趣的变量进行更即时和准确的评估。 参与者完成体格检查（包括抽血和尿样）、访谈和问卷调查，然后开始为期14天的EMA数据收集。 在EMA数据收集期间，在3个点收集营养数据系统数据。 研究人群包括患有AN的成年女性，或符合亚临床AN标准（低体重和闭经或AN的认知模式（身体形象障碍和对脂肪的强烈恐惧））的女性。 在基线时收集进食障碍症状、一般精神病理学、情绪状态和人格特征的测量值，并在整个EMA方案中收集关于进食障碍症状、情绪状态和人格特征的数据。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Subproject description. Anorexia Nervosa (AN) is a serious, often treatment-refractory mental illness with multiple medical complications and a high mortality rate. In spite of the significant medical and psychosocial complications associated with AN, conceptual models of the etiology and maintenance of this disorder are limited. The current research will develop and test a maintenance model predicting AN symptoms based on personality traits, momentary mood states, and cognitions, as well as life events. We are utilizing an assessment strategy that measures cognitions, behaviors, and moods of interest several times a day in order to provide a rigorous and fine grained examination of the thoughts, feelings and behaviors in AN. In order to minimize assessment error due to retrospective recall delays, an electronic self- monitoring system (ecological momentary assessment; EMA) is used to gain more immediate and accurate assessment of the variables of interest. Participants complete a physical examination (including blood draw and urine sample), interviews and questionnaires, and then begin EMA data collection for a period of 14 days. Nutritional Data System data is collected at 3 points during the EMA data collection. The study population consists of adult women with AN, or those who meet criteria for sub-clinical AN (low weight and either amenorrhea or the cognitive pattern of AN (body image disturbance and the intense fear of fat). Measures of eating disorder symptoms, general psychopathology, mood states, and personality characteristics are gathered at baseline and data on eating disorder symptoms, mood states and personality characteristics are gathered throughout the EMA protocol.
