Studies have demonstrated that negative affect increases prior to food intake in individuals diagnosed with an eating disorder. Mindfulness has been supported empirically to treat experiential avoidance stemming from anxiety. Thus, the current objective in this study is to empirically compare mindfulness vs. thought suppression invention during a food exposure in both clinical and nonclinical samples.
In a 2 (Group: clinical vs. nonclinical) × 2 (INTERVENTION: mindfulness vs. distraction) counterbalanced within treatment design, the current investigation sought to determine the differential effectiveness of a brief mindfulness intervention vs. a brief distraction intervention in women diagnosed with AN and BN in a clinical and nonclinical sample during a food exposure.
Results indicated that the eating disorder group reported a significant increase in negative affect after the mindfulness intervention as compared to the distraction intervention, whereas the nonclinical group reported a significant decrease in negative affect after the mindfulness intervention as compared to the distraction intervention.
Preliminary findings suggest that clinicians may want to proceed cautiously when using mindful eating in those with severe eating disorders during the early stages of food exposure. Limitations and future directions are discussed.
研究表明，在被诊断患有饮食失调症的个体中，负性情绪会在进食前增加。正念已被实证支持用于治疗源于焦虑的体验回避。因此，本研究的目的是在临床和非临床样本中实证比较正念与食物暴露期间的思维抑制发明。
在 2（组：临床与非临床）×2（干预：正念与分心）的平衡内处理设计中，本研究旨在确定在食物暴露期间，简短的正念干预与简短的分心干预对被诊断为 AN 和 BN 的女性在临床和非临床样本中的差异有效性。
结果表明，与分心干预相比，饮食失调组在正念干预后报告了显著增加的负性情绪，而与分心干预相比，非临床组在正念干预后报告了显著降低的负性情绪。
初步结果表明，临床医生在食物暴露的早期阶段，可能要谨慎地使用正念饮食来治疗严重的饮食失调症患者。讨论了限制因素和未来方向。
