METHODS: 45 participants were randomly allocated to one of three trial arms. Primary outcomes were recruitment, retention and treatment adherence rates. Secondary outcomes included measures of eating behaviour, mood, attention and treatment acceptability. Assessments were conducted at baseline, post-intervention (week 8), and follow-up (week 12).
RESULTS: Participant retention at follow-up was 84.5% across groups. Session completion rates in the laboratory were 87% for ABMT and 94% for MT, but home practice was much poorer for ABMT. Changes in BMI and body composition were small between groups and there was a medium size BMI reduction in the MT group at follow-up. Effect sizes of eating disorder symptom changes were not greater for either intervention group compared to WL, but favoured ABMT compared to MT. Hedonic hunger and mindful eating scores favoured MT compared to ABMT and WL. ABMT reduced attention biases towards high-calorie food cues, which correlated with lower objective binge eating days at post-intervention. No significant changes were observed in the MT, or WL conditions.
CONCLUSIONS: Both ABMT and MT have potential value as adjuncts in the treatment of obesity and BED, and a larger clinical trial appears feasible and indicated.
BACKGROUND: ISRCTN Registry, ISRCTN15745838. Registered on 22 May 2018.
In this small research study, people who were classified as overweight or living with obesity (with or without symptoms of binge eating disorder) received either a mindfulness intervention, a “subconscious” attention-based intervention called attention bias modification training (ABMT) or were put on a waiting list for 8 weeks. People in the mindfulness group experienced improvements in emotional eating, mindful eating, and “impulsive” eating. Those who received the attention-based training paid less attention to highly caloric food after the intervention which correlated with fewer binge eating episodes. Results from this study suggest that both types of interventions have potential as add-on treatments for obesity and binge eating disorder, but larger studies are necessary to assess their clinical impact.
方法:45名参与者被随机分配到三个试验组之一。主要结果是招募,保留率和治疗依从性。次要结果包括饮食行为的测量,心情,注意力和治疗可接受性。在基线时进行评估,干预后(第8周),和随访(第12周)。
结果:各组随访时参与者的保留率为84.5%。实验室的会话完成率ABMT为87%,MT为94%,但是ABMT的家庭实践要差得多。两组之间BMI和身体成分的变化很小,并且在随访时MT组的BMI降低中等。与WL相比,任何干预组的进食障碍症状变化的影响大小均不大,但与MT相比,ABMT更受青睐。与ABMT和WL相比,享乐饥饿和正念饮食得分更有利于MT。ABMT减少了对高热量食物线索的注意力偏见,这与干预后客观暴食天数较低相关。在MT中没有观察到显著的变化,或WL条件。
结论:ABMT和MT作为辅助治疗肥胖和BED的潜在价值,更大的临床试验似乎是可行的,并表明。

在这项小型研究中,被归类为超重或肥胖(有或没有暴食症的症状)的人接受了正念干预,一种“潜意识”的基于注意力的干预措施称为注意力偏倚改变训练(ABMT)或被列入8周的等待名单.正念组的人在情绪饮食方面经历了改善,正念吃,“冲动”的饮食。那些接受基于注意力的训练的人在干预后对高热量食物的关注较少,这与较少的暴饮暴食事件相关。这项研究的结果表明,这两种类型的干预措施都有可能作为肥胖和暴饮暴食症的附加治疗方法,但需要更大规模的研究来评估其临床影响.
