Mindfulness-based interventions have been increasingly applied to treat eating-related problems ranging from obesity to eating disorders. Yet few studies have empirically examined the mechanisms of a mindful approach to eating. The current studies examine the potential of brief mindfulness instructions to enhance the psychological and behavioral dimensions of eating.
In three experiments (total N = 319 undergraduates), we examined whether brief mindfulness instructions would enhance the positive sensory experience involved in tasting food as well as healthy eating behaviors.
Relative to distraction control instructions, the first two studies demonstrated that brief mindfulness instructions increased the enjoyment of a commonly pleasurable food (chocolate; Study 1), and a food with generally more mixed associations (raisins; Study 2). The third study replicated and extended these findings to show that brief mindfulness instructions also led to lower calorie consumption of unhealthy food relative to distracted or no-instruction control conditions, an effect mediated by greater eating enjoyment.
Findings demonstrated the power of brief mindfulness instructions to positively impact both health-relevant behavior and sensory experience associated with eating food. Implications for both theory and clinical applications of mindfulness are discussed.
基于正念的干预措施已越来越多地应用于治疗从肥胖到饮食失调等与饮食相关的问题。然而,很少有研究从实证角度检验正念饮食方法的作用机制。当前的研究探讨了简短的正念指导在增强饮食的心理和行为维度方面的潜力。
在三项实验中(总样本量N = 319名本科生),我们检验了简短的正念指导是否会增强品尝食物时的积极感官体验以及健康的饮食行为。
相对于分心控制指导,前两项研究表明,简短的正念指导增加了对一种通常令人愉悦的食物(巧克力;研究1)以及一种通常具有更多复杂联想的食物(葡萄干;研究2)的享受程度。第三项研究重复并扩展了这些发现,表明相对于分心或无指导的控制条件,简短的正念指导还导致不健康食物的卡路里摄入量更低,这一效应由更高的饮食享受程度介导。
研究结果证明了简短的正念指导对与饮食相关的健康行为和感官体验产生积极影响的作用。讨论了正念在理论和临床应用方面的意义。
