项目摘要

DESCRIPTION (provided by applicant): This study will focus on an innovative complementary use of placebo. The purpose is to determine if pairing a placebo with stimulant medication produces a conditioned placebo response that allows children with ADHD to be maintained on a lower dose of stimulant medication. Conditioned placebo treatment would potentially enhance clinical care of children with ADHD by decreasing side effects. A sample of 80 children with ADHD will be recruited to participate in a three-phase study: (1) an initial double-blind dose finding phase to identify each child's optimal stimulant dose (2) a dose reduction phase to compare subjects randomly assigned to either conditioned placebo dose reduction (100 percent of dose PLUS placebo -> 50 percent of dose PLUS placebo) or dose reduction only condition (100 percent of dose -> 50 percent of dose), and (3) a treatment maintenance phase to examine the duration of conditioned placebo effects among positive responders. Treatment response will be measured by parent and teacher rating scales, objective measures of attention, and side effects. The conditioned placebo procedure to be examined involves daily pairing of the full stimulant dose with a visually distinctive placebo pill for 1 month followed by stimulant dose reduction with continuation of the placebo. This method carries the potential for eliciting a conditioned response as has been done in other medical treatment contexts that have demonstrated significant conditioned placebo responses (e.g. placebo treatment of pain). A visually distinctive placebo pill (color, size, and indicia distinct from the stimulant pill) will be used as previous research has shown that the visual characteristics of a placebo can enhance its positive effects. In a pilot study of placebo treatment in children with ADHD (n = 26) we found that approximately 40% of a sample of children with ADHD could be maintained on 50% of their typical dose of stimulant medication when dose reduction was accomplished using the conditioned placebo procedure. Specific aims of the proposed study are: (1) to determine the efficacy, side effects and acceptability of conditioned placebo treatment, (2) to examine specific treatment effects and persistence of effects over time, and (3) to identify predictors of conditioned placebo response.

描述（由申请方提供）：本研究将重点关注安慰剂的创新性补充使用。目的是确定安慰剂与兴奋剂药物配对是否产生条件安慰剂反应，使ADHD儿童能够维持较低剂量的兴奋剂药物。条件性安慰剂治疗可能会通过减少副作用来增强ADHD儿童的临床护理。将招募80名ADHD儿童样本参加三阶段研究：（1）最初的双盲剂量探索阶段，以确定每个儿童的最佳兴奋剂剂量（2）剂量减少阶段，以比较随机分配到条件安慰剂剂量减少的受试者（100%剂量+安慰剂-> 50%剂量+安慰剂）或仅减量条件（100%剂量-> 50%剂量），和（3）治疗维持期，以检查阳性应答者中条件安慰剂效应的持续时间。治疗反应将通过家长和教师评定量表、注意力的客观测量和副作用来测量。待检查的条件安慰剂程序包括每日将全部兴奋剂剂量与视觉上独特的安慰剂药丸配对1个月，然后减少兴奋剂剂量并继续安慰剂。这种方法具有引发条件反应的潜力，正如在其他医学治疗背景下所做的那样，这些背景已经证明了显著的条件安慰剂反应（例如，安慰剂治疗疼痛）。将使用视觉上独特的安慰剂药丸（颜色，大小和标记与兴奋剂药丸不同），因为先前的研究表明，安慰剂的视觉特征可以增强其积极作用。在一项对ADHD儿童进行安慰剂治疗的初步研究（n = 26）中，我们发现，当使用条件安慰剂程序减少剂量时，大约40%的ADHD儿童样本可以维持其典型剂量的50%的兴奋剂药物。拟议研究的具体目的是：（1）确定条件安慰剂治疗的疗效、副作用和可接受性，（2）检查特定治疗效果和随时间推移的效果持续性，以及（3）确定条件安慰剂反应的预测因子。
