背景资料：肥胖是一个日益增长的全球性问题，是与认知和心理defictions.Objective：本初步研究调查的有效性，以提高抑制控制（IC），一个过程，与暴饮暴食，对消费和认知控制factors.Methods：本研究利用了多会话移动的电话为基础的干预训练IC超重和肥胖人群使用随机候补对照设计。自我评估问卷和心理生理学措施相结合，用于评估改善一般IC和修改后的训练后的食物消耗方面的干预效果。对食物的态度也进行了评估，以确定其在食物选择中的中介作用。共有58名参与者（47名女性）完成了2次评估，间隔3周，在此期间培训组进行了2周的干预培训。组没有不同的基线人口统计学，包括年龄，体重指数，和抑制control.Results：抑制控制能力提高整个培训课程，P3振幅的增加意味着增加认知控制的反应。抑制控制训练与增加健康和减少不健康的食物消费在味觉测试和训练后的一周内，通过健康饮食测验和食物消费测试测量。训练后的培训，但不是候补条件的三因素饮食调查问卷，这意味着，试图避免不健康的食物在未来将更容易为培训组participant.Conclusions：抑制控制训练通过一个专门设计的移动的手机应用程序是很容易完成的，是方便的，可以增加认知抑制，减少不健康的食物消费。
Background: Obesity is a growing global issue that is linked to cognitive and psychological deficits.Objective: This preliminary study investigated the efficacy of training to improve inhibitory control (IC), a process linked to overeating, on consumption and cognitive control factors.Methods: This study utilized a multisession mobile phone-based intervention to train IC in an overweight and obese population using a randomized waitlist-control design. A combination of self-assessment questionnaires and psychophysiological measures was used to assess the efficacy of the intervention in terms of improved general IC and modified food consumption after training. Attitudes toward food were also assessed to determine their mediating role in food choices. A total of 58 participants (47 female) completed 2 assessment sessions 3 weeks apart, with 2 weeks of intervention training for the training group during this time. The groups did not differ in baseline demographics including age, body mass index, and inhibitory control.Results: Inhibitory control ability improved across the training sessions, with increases in P3 amplitude implying increased cognitive control over responses. Inhibitory control training was associated with increased healthy and reduced unhealthy food consumption in a taste test and in the week following training, as measured by the Healthy Eating Quiz and the food consumption test. Cognitive restraint was enhanced after training for the training but not the waitlist condition in the Three-Factor Eating Questionnaire, implying that attempts to avoid unhealthy foods in the future will be easier for the training group participants.Conclusions: Inhibitory control training delivered via a purpose-designed mobile phone app is easy to complete, is convenient, and can increase cognitive restraint and reduce unhealthy food consumption.
