Two online surveys were conducted to assess the relationship between trait disinhibition, impulsivity, mindfulness and adverse psychological symptoms. In study 1 adult females (n=196; mean age=21 yrs) completed the Three-Factor Eating Questionnaire (TEFQ-R21), the Hospital Anxiety and Depression Scale and a measure of dispositional mindfulness. In study 2 adult females (n=190; mean age=26 yrs) completed the same measures as in study 1 with the addition of the Barratt Impulsivity Scale. In both studies it was predicted that mindfulness would be negatively related to trait disinhibition controlling for adverse psychological symptoms. The second study addressed the additional hypothesis that the relationship between mindfulness and trait disinhibition would be mediated by impulsivity. Regression analyses indicated that mindfulness was negatively related to and explained 11% of variation in trait disinhibition (study 1). This relationship was replicated and extended in study 2 whereby impulsivity mediated the relationship between mindfulness and trait disinhibition. The findings warrant experimental and in vivo investigations of the potential causal relationships between mindfulness, impulsivity and eating behaviours.
进行了两项在线调查，以评估特质抑制、冲动、正念和不良心理症状之间的关系。在研究 1 中，成年女性（n=196；平均年龄 21 岁）完成了三因素饮食问卷（TEFQ-R21）、医院焦虑和抑郁量表以及特质正念量表。在研究 2 中，成年女性（n=190；平均年龄 26 岁）完成了与研究 1 相同的测量，此外还增加了巴雷特冲动量表。在这两项研究中，都预测正念与特质抑制之间存在负相关，控制了不良心理症状。第二项研究进一步假设，正念与特质抑制之间的关系受冲动的影响。回归分析表明，正念与特质抑制呈负相关，可解释特质抑制变异的 11%（研究 1）。在研究 2 中，该关系得到了复制和扩展，其中冲动中介了正念与特质抑制之间的关系。这些发现证明了在正念、冲动和饮食行为之间的潜在因果关系方面进行实验和体内研究是合理的。
