Not responding to appetitive food items in the go/no-go training has been shown to reduce the evaluation of these items in normal-weight university students. In this preregistered study, we administered an identical go/no-go training in both morbidly obese individuals and normal-weight university students, to assess whether findings from laboratory studies on go/no-go training performed in university environments can be translated to clinical settings.
Obese individuals (N = 59, 14 males, M = 46.10, MBMI = 44.49) and university students (N = 58, 15 males, M = 23.21, MBMI = 22.64) were trained to consistently respond to certain food items (go) and withhold responses to other items (no-go). Evaluations of the go and no-go items, along with items not used in the training (untrained), were measured both before and after the training.
Before the training, evaluations of go, no-go and untrained items were matched; after the training, go items were evaluated more positively than no-go (p = .031 and p = .002 in obese and normal-weight individuals) and untrained items (p = .003 in normal-weight individuals). Only relatively hungry participants rated no-go items as less attractive than both go and untrained items (no-go devaluation effect). More important, effects of the training on food evaluation did not differ between the two participant groups.
Obese and normal-weight individuals showed similar responsivity to the go/no-go training on food evaluation, suggesting that insights from laboratory studies may be translated to clinical settings to develop effective interventions to regulate food intake.

在go/no-go 训练中对开胃食物无反应已被证明可以降低正常体重大学生对这些食物的评价。在这项预先注册的研究中，我们对肥胖个体和正常体重大学生进行了相同的 go/no-go 训练，以评估在大学环境中进行的 go/no-go 训练的实验室研究结果是否可以转化为临床环境。
肥胖个体（N=59，男性 14 人，M=46.10，MBMI=44.49）和大学生（N=58，男性 15 人，M=23.21，MBMI=22.64）接受训练以一致地对某些食物（go）做出反应，并对其他食物（no-go）做出反应。在训练前后，对 go 和 no-go 项目以及未在训练中使用的项目（未训练）进行评估。
在训练之前，go、no-go 和未训练项目的评估是匹配的；训练后，go 项目的评价比 no-go（肥胖和正常体重个体中 p =.031 和 p =.002）和未训练项目（正常体重个体中 p =.003）更积极。只有相对饥饿的参与者将 no-go 项目评为不如 go 和未训练项目有吸引力（no-go 贬值效应）。更重要的是，训练对食物评价的影响在两个参与者组之间没有差异。
肥胖和正常体重个体在食物评价的 go/no-go 训练中表现出相似的反应性，这表明实验室研究的见解可以转化为临床环境，以开发有效的干预措施来调节食物摄入。（PsycINFO 数据库记录（c）2018 APA，保留所有权利）。
