EATING DISORDERS AND IMPULSIVITY--A LONGITUDINAL STUDY

越来越多的经验证据表明，具有高度特质冲动的进食障碍个体中有相当一部分表现出复杂的精神病理，他们的进食障碍的负面过程，并且对传统的进食障碍治疗没有很好的反应。关于这些人的日常活动和行为模式的数据非常少，经常被称为“多冲动”或临界型进食障碍患者。此外，显然没有对这些人进行有效的治疗。这项资助代表了一个关于进食紊乱个体的自毁行为的概念模型，该模型结合了特征结构和日常事件、情绪和行为，以解释这种自毁行为。该模型具体考察了某些人格特征(情感不稳定、冲动)、童年逆境、日常事件、日常情绪和日常应对行为在预测自我毁灭行为中的作用。此外，本研究建议使用电子日记技术来测试该模型，以评估感兴趣的行为。我们相信，这种方法将提供可靠的数据，较少受到追溯回忆偏差的影响，这是该领域以前研究的特点。120名受试者将连续30天完成电子日记，这将允许收集足够数量的数据来充分测试所提出的模型。我们相信，这一方法论将使我们能够确定进食障碍个体自我毁灭行为的前因和后遗症。这将提供有关为这一群体开发治疗方法的重要信息。

There is increasing empirical evidence suggesting that a significant subset of eating disordered individuals with high degrees of trait impulsivity display complicated psychopathology, negative course of their eating disorder, and do not respond well to traditional eating disorder treatments. Very little data is available about the day-to-day activities and behavioral patterns of these individuals, frequently referred to as "mu1ti-impulsive" or borderline-type eating disordered patients. Furthermore, there is apparently no effective treatment for these individuals. This grant represents a conceptual model of self-destructive behavior in eating disordered individuals which incorporates both trait-constructs and daily events, moods, and behaviors to account for such self-destructive behavior. This model specifically examines the role of certain personality traits (affective lability, impulsivity), childhood adversity, daily events, daily moods, and daily coping behaviors in the prediction of self-destructive behavior. Furthermore, the present study proposes to test this model utilizing electronic daily diary technology to assess the behaviors of interest. We believe that this methodology will provide reliable data that is less affected by retrospective recall bias which characterizes previous research in this area. One hundred and twenty subjects will complete electronic diaries for thirty consecutive days, which will allow the collection of a sufficient amount of data to adequately test the proposed model. We believe that this methodology will allow us to identify antecedent and consequent conditions surrounding self-destructive behavior in eating disordered individuals. This will provide important information regarding the development of treatments for this group of individuals.
