Anorexia nervosa (AN) is a serious psychiatric disorder that is difficult to treat and often follows a protracted course. A number of theoretical models have been proposed for the etiology and maintenance of AN. Two domains that have received substantial attention in the literature on AN are affect and reward/punishment processes. However, despite an overlap in the nature and implications of these processes, studies of AN addressing these constructs have typically investigated them independently.
The purpose of this narrative review is to integrate the literature on the role of affect, reward, and punishment in AN.
We provide a focused narrative overview of the literature relating to the affect, reward, and punishment in AN via a synthesis of recent reviews and meta-analyses.
We first describe several prominent affect and reward/punishment-based conceptualizations of AN, followed by a brief overview of the existing empirical literature in these domains.
We provide a critical discussion of the disparate nature of these literatures in AN, including associated limitations. We then conclude with an extensive discussion of directions for future research that integrate the study of affect and reward/punishment processes in AN.
Level V, narrative review.
神经性厌食症（AN）是一种严重的精神疾病，难以治疗且病程往往迁延。针对神经性厌食症的病因及维持因素，已提出了多种理论模型。在神经性厌食症相关文献中受到大量关注的两个领域是情感和奖惩过程。然而，尽管这些过程在性质和影响方面存在重叠，但针对这些构念的神经性厌食症研究通常是独立进行调查的。
本叙述性综述的目的是整合关于情感、奖励和惩罚在神经性厌食症中作用的文献。
通过综合近期的综述和荟萃分析，我们对与神经性厌食症中的情感、奖励和惩罚相关的文献进行了重点叙述性概述。
我们首先描述了几种基于情感和奖惩的神经性厌食症突出概念化，随后简要概述了这些领域现有的实证文献。
我们对神经性厌食症这些文献的不同性质进行了批判性讨论，包括相关局限性。然后我们以对未来研究方向的广泛讨论作为结尾，这些研究方向整合了神经性厌食症中情感和奖惩过程的研究。
V级，叙述性综述。
