The present study aimed to explore the relationship between difficulties in emotion regulation and deficits in inhibitory control, and the role of these processes in eating psychopathology in a non-clinical sample. We also explored the specificity in which deficits in inhibitory control may underlie eating psychopathology, namely whether they can be conceptualised as context specific or more extensive in nature.
Participants were 107 healthy individuals recruited at a major Portuguese university, aged between 18 and 43 years-old (M = 21.23, SD = 4.79). Two computerised neuropsychological tasks (i.e., emotional go/no-go and food go/no-go tasks) were used to assess response inhibition in the presence of general versus context-specific stimuli. A set of self-report measures was used to assess variables of interest such as emotion regulation and eating psychopathology.
Results indicated higher response inhibition deficits among participants with higher difficulties in emotion regulation comparing to those with lower difficulties in emotion regulation, particularly in the context of food-related stimuli. In addition, the relationship between difficulties in emotion regulation and eating psychopathology was moderated by inhibitory control deficits in both the context of food and pleasant stimuli.
The present findings highlight inhibitory control as an important process underlying the relationship between difficulties in emotion regulation and eating psychopathology in non-clinical samples. Findings have important implications for clinical practice and the prevention of eating psychopathology in healthy individuals and individuals with eating disorders.
本研究旨在探讨情绪调节困难与抑制控制缺陷之间的关系，以及这些过程在非临床样本饮食心理病理学中的作用。我们还探讨了抑制控制缺陷可能构成饮食心理病理学基础的特异性，即它们是否可被概念化为特定情境下的或本质上更广泛的。
参与者是在一所主要的葡萄牙大学招募的107名健康个体，年龄在18至43岁之间（M = 21.23，SD = 4.79）。使用两项计算机化神经心理学任务（即情绪性停止信号任务和食物停止信号任务）来评估在一般刺激与特定情境刺激存在时的反应抑制。使用一组自我报告测量方法来评估诸如情绪调节和饮食心理病理学等感兴趣的变量。
结果表明，与情绪调节困难较低的参与者相比，情绪调节困难较高的参与者的反应抑制缺陷更高，特别是在与食物相关的刺激情境中。此外，在食物和愉悦刺激情境中，情绪调节困难与饮食心理病理学之间的关系受到抑制控制缺陷的调节。
本研究结果突出了抑制控制是情绪调节困难与非临床样本饮食心理病理学之间关系的一个重要潜在过程。研究结果对临床实践以及健康个体和饮食失调个体饮食心理病理学的预防具有重要意义。
