: Binge eating is a disordered eating behavior implicated in eating disorders such as binge eating disorder (BED) and bulimia nervosa; it significantly affects an individual's physical and mental health. Recent studies suggest shared neurobiological mechanisms between binge eating and addictive behaviors. Comorbid addiction (e.g., substance use disorders and behavioral addictions) is also frequently reported in binge-eating patients. However, it is still unclear whether binge-eating individuals with comorbid addictions differ in their cognitive and mental health characteristics from those without comorbid addictions. : The present study aimed to examine the cognitive and mental health profiles of binge-eating individuals with and without co-occurring addictions. We hypothesized that binge-eating individuals with comorbid addictions would show greater impairments in impulsivity and self-control, as well as elevated depression and emotion dysregulation. : In the present study, we assessed psychometric scales on various cognitive and mental health domains (e.g., impulsivity, behavioral inhibition, self-control, emotion regulation, mood, and anxiety) across 30 binge-eating individuals with co-occurring addictive behaviors (i.e., alcohol, nicotine, gambling, and video games), 32 binge-eating individuals without addiction, and 180 healthy control subjects with neither binge-eating tendencies nor addiction. : Both binge-eating groups showed a significant increase in punishment sensitivity, perceived stress, and state/trait anxiety compared to healthy controls, but there was no difference between the two binge-eating groups. Higher impulsivity and lower self-control were observed in both binge-eating groups to a significantly greater degree in the group with comorbid addiction. Notably, significantly increased depression and impaired emotion regulation (reduced use of cognitive reappraisal) were observed only in the binge-eating group with comorbid addiction when compared to the healthy controls. : Our findings demonstrated the commonalities and differences in binge-eating populations with and without comorbid addiction. It will help to elucidate cognitive and mental health aspects of comorbid addiction in the binge-eating population and to develop more tailored diagnoses and treatments.
暴饮暴食是一种与饮食失调相关的紊乱饮食行为，如暴饮暴食障碍（BED）和神经性贪食症；它会显著影响个体的身心健康。最近的研究表明，暴饮暴食和成瘾行为之间存在共同的神经生物学机制。暴饮暴食患者中也经常报告有共病成瘾（如物质使用障碍和行为成瘾）。然而，有共病成瘾的暴饮暴食个体在认知和心理健康特征上是否与没有共病成瘾的个体不同，目前仍不清楚。
本研究旨在检查有和没有共病成瘾的暴饮暴食个体的认知和心理健康状况。我们假设，有共病成瘾的暴饮暴食个体在冲动性和自我控制方面会表现出更大的损伤，同时抑郁和情绪调节障碍也会加剧。
在本研究中，我们对30名有共病成瘾行为（即酒精、尼古丁、赌博和电子游戏成瘾）的暴饮暴食个体、32名无成瘾的暴饮暴食个体以及180名既无暴饮暴食倾向也无成瘾的健康对照者，进行了各种认知和心理健康领域（如冲动性、行为抑制、自我控制、情绪调节、情绪和焦虑）的心理测量量表评估。
与健康对照组相比，两个暴饮暴食组的惩罚敏感性、感知压力以及状态/特质焦虑均显著增加，但两个暴饮暴食组之间没有差异。在两个暴饮暴食组中均观察到较高的冲动性和较低的自我控制能力，其中有共病成瘾的组更为明显。值得注意的是，与健康对照组相比，只有有共病成瘾的暴饮暴食组出现了显著增加的抑郁和受损的情绪调节（认知重评使用减少）。
我们的研究结果揭示了有和没有共病成瘾的暴饮暴食人群的异同。这将有助于阐明暴饮暴食人群中共病成瘾的认知和心理健康方面，并制定更具针对性的诊断和治疗方法。
