Eating disorders (EDs) and anxiety disorders (ADs) evidence shared risk and significant comorbidity. Recent advances in understanding of anxiety-based disorders may have direct application to research and treatment efforts for EDs. The current review presents an up-to-date, behavioral conceptualization of the overlap between anxiety-based disorders and EDs. We identify ways in which anxiety presents in EDs, consider differences between EDs and ADs relevant to treatment adaptions, discuss how exposure-based strategies may be adapted for use in ED treatment, and outline directions for future mechanistic, translational, and clinical ED research from this perspective. Important research directions include: simultaneous examination of the extent to which EDs are characterized by aberrant avoidance-, reward-, and/or habit-based neurobiological and behavioral processes; improvement in understanding of how nutritional status interacts with neurobiological characteristics of EDs; incorporation of a growing knowledge of biobehavioral signatures in ED treatment planning; development of more comprehensive exposure-based treatment approaches for EDs; testing whether certain exposure interventions for AD are appropriate for EDs; and improvement in clinician self-efficacy and ability to use exposure therapy for EDs.

饮食失调 (EDs) 和焦虑症 (ADs) 的证据表明存在共同的风险和显着的合并症。对基于焦虑症的理解的最新进展可能直接应用于 ED 的研究和治疗工作。目前的审查提出了基于焦虑的障碍和 ED 之间重叠的最新的行为概念化。我们确定了焦虑症在 ED 中的表现方式，考虑了 ED 和 AD 与治疗适应相关的差异，讨论了基于暴露的策略如何适用于 ED 治疗，并概述了未来机械、转化和临床 ED 研究的方向这个观点。重要的研究方向包括：同时检查 ED 以异常回避-、奖励-、和/或基于习惯的神经生物学和行为过程；提高对营养状况如何与 ED 的神经生物学特征相互作用的理解；将越来越多的生物行为特征知识纳入 ED 治疗计划；为 ED 开发更全面的基于暴露的治疗方法；测试某些针对 AD 的暴露干预措施是否适用于 ED；提高临床医生的自我效能感和对 ED 使用暴露疗法的能力。测试某些针对 AD 的暴露干预措施是否适用于 ED；提高临床医生的自我效能感和对 ED 使用暴露疗法的能力。测试某些针对 AD 的暴露干预措施是否适用于 ED；提高临床医生的自我效能感和对 ED 使用暴露疗法的能力。
