DESCRIPTION (provided by applicant): This study will use methods, techniques, and findings from the fields of affect and emotion, behavioral assessment, and psychometrics to shed light on a core feature of BPD, affective instability. In this revised application, we propose to conduct an intensive study of affective instability using ecological momentary assessment (EMA) --- a real time assessment of behaviors, emotions, and cognitive variables via hand held computers. Study participants will include 75 BPD outpatients and 75 psychiatric controls (with Major Depressive Disorder) who will rate their mood states, behaviors, and life events six times per day for a 28 day period. We will address four major aims: (1) characterize the mood state patterns of BPD patients and contrast these patterns with those of patients of near-neighbor diagnoses (in this case major depression); (2) identify antecedents (life events) and consequents (substance use behaviors) of mood shifts; (3) determine whether BPD patients can accurately recall (via retrospective self-report instruments) their mood shifts and variables associated with these shifts; and (4) assess whether existing measures of affective instability, affective intensity, and personality are related to EMA measures of affective variability and mood shifts. This study will represent the most intensive, naturalistic study of affective instability, and it will address several theoretical questions regarding affective instability. Further, these results will have implications for treatment and for the assessment of affective instability. Funding for this study will allow us to provide multidisciplinary training to an advanced graduate student who plans to conduct research in this area in the future. Completion of this study will also enable us to conduct multiple studies aimed at elucidating the utility of EMA in the assessment of BPD and the utility of EMA in tracking treatment effects, as well as to take part in the development of a multidisciplinary center for the study of BPD and its features that will foster collaborations among scientists with expertise in psychometrics and measurement theory, psychobiology, social and affective neuroscience, and basic behavioral science.

描述（由申请人提供）：本研究将使用方法，技术和影响和情绪，行为评估和心理测量学领域的发现来阐明BPD的核心特征，情感不稳定性。在这个修订后的应用程序中，我们建议进行深入研究的情感不稳定性，使用生态瞬时评估（EMA）---一个真实的时间评估的行为，情绪和认知变量，通过手持计算机。研究参与者将包括75名BPD门诊患者和75名精神病对照（患有重度抑郁症），他们将在28天内每天6次评估他们的情绪状态，行为和生活事件。本研究的主要目的有四：（1）描述BPD患者的情绪状态模式，并将其与近邻诊断患者的情绪状态模式进行对比（在这种情况下，严重抑郁症）;（2）确定前因（生活事件）和后果（物质使用行为）的情绪变化;（3）确定BPD患者是否能准确回忆（通过回顾性自我报告工具）他们的情绪变化和与这些变化相关的变量;以及（4）评估现有的情感不稳定性、情感强度和个性的测量是否与情感变异性和情绪变化的EMA测量相关。这项研究将代表情感不稳定性的最密集的，自然主义的研究，它将解决有关情感不稳定性的几个理论问题。此外，这些结果将对治疗和情感不稳定的评估产生影响。这项研究的资金将使我们能够提供多学科的培训，以先进的研究生谁计划在这一领域进行研究的未来。本研究的完成还将使我们能够进行多项研究，旨在阐明EMA在BPD评估中的效用以及EMA在跟踪治疗效果中的效用，并参与多学科中心的发展，以研究BPD及其特征，这将促进具有心理测量学和测量理论，心理生物学，社会和情感神经科学以及基础行为科学。
