DESCRIPTION (provided by applicant): Dietary restriction (DR), or inadequate caloric and nutrient consumption, is a shockingly common practice associated with serious medical and psychological consequences. DR predicts development of both overweight and eating disorders. At its extreme, DR can develop into anorexia nervosa (AN), a serious and chronic disorder associated with considerable morbidity and lifetime mortality up to 20%. Despite the negative effects of DR, the psychological processes driving this behavior have received little attention and remain poorly understood. While certain psychological processes (e.g., excessive self-control; emotion dysregulation) have been hypothesized to be involved in DR, the models proposing the importance of these processes have not been adequately tested. As a result, treatments of DR are inadequate. No efficacious treatments have been identified for adults with AN and, DR interferes with treatment for other eating disorders, and the guidelines for addressing DR in treatment of other related disorders (e.g., depression) are unspecified. Research design issues hinder progress in understanding and treating DR. Traditionally, randomized, controlled trials (RCTs) have been used to investigate treatment for DR, yet this is often an impractical first step for investigating treatment targets. Further, self-report measures f eating behavior, which are unreliable, have been over-utilized. The current study proposes to address these problems by examining the effects of 2 brief interventions targeting different psychological processes (self-control, emotion dysregulation) hypothesized to affect DR, compared to an active control, on a behavioral measure of the amount of effort restrictive eaters exert to reduce caloric intake at a test meal. Individuals identified as engaging in frequent DR will be told they will be expected to consume a self-selected quantity of a high-calorie milkshake and participate in an intervention that may help them tolerate this experience. Subjects will then be randomized to receive 1 of 3 brief computer- guided interventions: 1) cognitive restructuring (targeting self-control), 2) emotion regulation skills (targeting emotion dysregulation), or 3) nutrition information (control). Following the intervention, subjects will be given the option to work (by pressing the space bar on a computer task) to either: 1) decrease the number of calories they will be expected to consume, or 2) increase monetary compensation. The primary dependent variable will be number of button presses (i.e., effort) subjects employ toward reducing intake. This study is innovative due to utilization of: 1) Brief interventions targeting psychological processes, as opposed to RCTs, representing a time- and cost- effective means of evaluating promising psychological targets for DR; 2) A behavioral measure of a DR-related outcome, as opposed to self-report methods, presenting a more methodological precision. Results of this study will provide information regarding the psychological processes involved in DR, informing treatment development for DR. This has potential to make a substantial impact, as currently no efficacious treatments exist for DR, despite its commonality and potential for severe outcomes.

描述（由申请人提供）：饮食限制（DR），或热量和营养摄入不足，是一种与严重的医疗和心理后果相关的令人震惊的普遍做法。 DR 预测超重和饮食失调的发展。在极端情况下，DR 可发展为神经性厌食症 (AN)，这是一种严重的慢性疾病，发病率很高，终生死亡率高达 20%。尽管 DR 存在负面影响，但驱动这种行为的心理过程却很少受到关注，而且仍然知之甚少。虽然某些心理过程（例如过度自我控制、情绪失调）被假设与 DR 相关，但提出这些过程重要性的模型尚未经过充分测试。因此，DR 的治疗是不充分的。对于患有 AN 的成人，尚未确定有效的治疗方法，并且 DR 会干扰其他饮食失调的治疗，并且在治疗其他相关疾病（例如抑郁症）时解决 DR 的指南也未明确。研究设计问题阻碍了对 DR 的理解和治疗的进展。传统上，随机对照试验 (RCT) 已被用来研究 DR 的治疗方法，但这通常是研究治疗目标的不切实际的第一步。此外，自我报告的饮食行为测量方法并不可靠，而且被过度使用。目前的研究建议通过检查两种针对不同心理过程（自我控制、情绪失调）的简短干预措施的效果来解决这些问题，这些心理过程假设会影响 DR，与主动对照组相比，对限制性饮食者努力程度的行为测量进行比较努力减少测试餐中的热量摄入。被确定患有频繁 DR 的个人将被告知，他们将被要求饮用自行选择数量的高热量奶昔，并参与可能帮助他们忍受这种经历的干预措施。然后，受试者将被随机分配接受 3 种简短的计算机引导干预中的 1 种：1）认知重建（针对自我控制），2）情绪调节技能（针对情绪失调），或 3）营养信息（控制）。干预后，受试者可以选择工作（通过按计算机任务上的空格键）来：1）减少他们预计消耗的卡路里数量，或 2）增加金钱补偿。主要因变量是受试者为减少摄入量而按下按钮的次数（即努力程度）。这项研究的创新之处在于：1）针对心理过程的简短干预措施，而不是随机对照试验，代表了一种评估有希望的 DR 心理目标的时间和成本有效的方法； 2) 与自我报告方法相反，对 DR 相关结果进行行为测量，呈现出更精确的方法。这项研究的结果将提供有关 DR 所涉及的心理过程的信息，为 DR 的治疗开发提供信息。这有可能产生重大影响，因为尽管 DR 具有普遍性并且可能导致严重后果，但目前尚无有效的治疗方法。
