EATING DISORDERS AND IMPULSIVITY--A LONGITUDINAL STUDY

越来越多的经验证据表明，具有高度特质性冲动的饮食失调个体中有相当一部分人表现出复杂的精神病理，他们的饮食失调过程消极，对传统的饮食失调治疗反应不佳。关于这些人的日常活动和行为模式的数据很少，这些人通常被称为“多重冲动”或边缘型饮食失调患者。此外，对这些人显然没有有效的治疗方法。这一资助代表了饮食失调个体的自我毁灭行为的概念模型，它结合了特征构建和日常事件、情绪和行为来解释这种自我毁灭行为。该模型特别研究了某些人格特征（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，本研究建议利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，较少受到回顾性回忆偏差的影响，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拟议的模型。我们相信，这种方法将使我们能够识别饮食失调患者自我毁灭行为的前因缘和后因缘。这将为这一群体的治疗发展提供重要信息。

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.
