Approach-avoidance training (AAT) is a promising approach in obesity treatment. The present study examines whether an AAT is feasible and able to influence approach tendencies in children and adolescents, comparing implicit and explicit training approaches. Design/Setting/Subjects Fifty-nine overweight children and adolescents (aged 8-16 years; twenty-six boys) participated in an AAT for food cues, learning to reject snack items and approach vegetable items. Reaction times in the AAT and an implicit association test (IAT) were assessed pre- and post-intervention.
A significant increase in the AAT compatibility scores with a large effect (η 2=0·18) was found. No differences between the implicit and explicit training approaches and no change in the IAT scores were observed.
Automatic tendencies in children can be trained, too. The implementation of AAT in the treatment of obesity might support the modification of an unhealthy nutrition behaviour pattern. Further data from randomized controlled clinical trials are needed.
趋近-回避训练（AAT）是肥胖治疗中很有前途的一种方法。本研究通过比较内隐和外显训练方法，检验 AAT 是否可行以及能否影响儿童和青少年的趋近倾向。设计/环境/对象：59 名超重儿童和青少年（8-16 岁；男 26 名）参加了针对食物线索的 AAT，学习拒绝零食，选择蔬菜。干预前后评估了 AAT 和内隐联想测试（IAT）的反应时间。
发现 AAT 兼容性评分显著增加，具有较大效应（η 2=0·18）。内隐和外显训练方法之间没有差异，IAT 评分也没有变化。
儿童的自动倾向也可以被训练。在肥胖症的治疗中实施 AAT 可能有助于改变不健康的营养行为模式。还需要来自随机对照临床试验的更多数据。
