Irrational beliefs (IB) are believed, in cognitive behavioral therapies, to be a prime cause of psychopathologies including anxiety, depression, problem eating, and alcohol misuse. "Food addiction" (FA), which has been modeled on diagnostic criteria for substance use disorder, and emotional eating (EE) have both been implicated in the rise in overweight and obesity. Both FA and EE are associated with anxiety. Thus, in the present study, the hypothesis that IB is associated with FA and with EE was tested. Furthermore, possible mediation of these relationships by trait anxiety and depression (and EE for IB and FA) was examined. The responses of 239 adult participants to questionnaires measuring FA, IB, EE, depression, trait anxiety, and anthropometrics were recorded. The results revealed that IB was significantly positively correlated with FA and EE (and depression and trait anxiety). Furthermore, only EE mediated the effect of IB on FA and this was not moderated by BMI. Finally, trait anxiety (but not depression) mediated the effect of IB on EE. Exploratory analysis revealed a significant serial mediation such that IB predicted higher FA via elevated trait anxiety and emotional eating in that order. The results of this study suggest that IB may be a source of the anxiety that is associated with EE and FA and suggest that clinicians may find IB a target for treatment of those persons who report experiences of EE and FA. IB may play a role in food misuse that leads to elevated BMI.
非理性信念（IB）被认为是包括焦虑、抑郁、饮食问题和酗酒在内的许多精神病理学的主要原因。“食物成瘾”（FA）是根据物质使用障碍的诊断标准建模的，而情绪化进食（EE）都与超重和肥胖的增加有关。FA 和 EE 都与焦虑有关。因此，在本研究中，检验了 IB 与 FA 和 EE 相关的假设。此外，还研究了特质焦虑和抑郁（以及 EE 对 IB 和 FA）对这些关系的可能中介作用。记录了 239 名成年参与者对测量 FA、IB、EE、抑郁、特质焦虑和人体测量学的问卷的反应。结果表明，IB 与 FA 和 EE（以及抑郁和特质焦虑）呈显著正相关。此外，只有 EE 中介了 IB 对 FA 的影响，而 BMI 并没有调节这种影响。最后，特质焦虑（而不是抑郁）中介了 IB 对 EE 的影响。探索性分析显示出显著的序列中介作用，即 IB 通过提高特质焦虑和情绪进食依次预测更高的 FA。这项研究的结果表明，IB 可能是与 EE 和 FA 相关的焦虑的来源，并表明临床医生可能会发现 IB 是那些报告 EE 和 FA 经历的人的治疗目标。IB 可能在导致 BMI 升高的食物滥用中发挥作用。
