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，是一种令人震惊的常见做法，与严重的医疗和心理后果有关。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，与相当高的发病率和高达20%的终身死亡率相关。尽管DR有负面影响，但驱动这种行为的心理过程很少受到关注，并且仍然知之甚少。虽然某些心理过程（例如，过度的自我控制;情绪失调）被假设参与DR，提出这些过程的重要性的模型尚未得到充分的测试。因此，DR的治疗是不充分的。对于患有AN的成年人，还没有确定有效的治疗方法，DR干扰其他进食障碍的治疗，并且在治疗其他相关疾病（例如，抑郁症）未指定。传统上，随机对照试验（RCT）已被用于研究DR的治疗，但这往往是一个不切实际的第一步调查治疗目标。此外，饮食行为的自我报告措施，这是不可靠的，已被过度使用。目前的研究建议通过检查针对不同的心理过程（自我控制，情绪失调）假设影响DR的2个简短的干预措施的效果来解决这些问题，与主动控制相比，限制性饮食者在测试餐中减少热量摄入的努力量的行为测量。被确定为频繁参与DR的个体将被告知他们将被期望消耗自选量的高热量奶昔，并参与可能帮助他们耐受这种经历的干预。然后将受试者随机接受3种简短的计算机引导干预之一：1）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（对照）。干预后，受试者将被给予工作选项（通过按下计算机任务上的空格键），以：1）减少他们预计消耗的卡路里数量，或2）增加货币补偿。主要因变量将是按钮按下次数（即，努力）受试者用于减少摄入量。本研究具有创新性，因为它利用了：1）针对心理过程的简短干预，而不是RCT，代表了一种时间和成本效益高的方法来评估DR的有希望的心理目标; 2）DR相关结局的行为测量，而不是自我报告方法，提供了更精确的方法。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，因为目前还没有有效的DR治疗方法，尽管其具有共性和严重结局的可能性。
