Habits, characterized by automaticity and insensitivity to outcomes, may be key to the persistence of maladaptive behaviors in anorexia nervosa (AN). This review examines the status of habit research in AN, focusing on insights from task-based assessments.
Findings indicate dysfunction in the frontostriatal circuits associated with habitual and goal-directed behaviors, with some studies linking neural disturbances to habit measures or clinically relevant behaviors. Heightened habitual tendencies in AN have consistently been reported using self-reports, while research utilizing experimental paradigms has yielded mixed results and efforts to capture real-world habits in AN remain limited. Some experimental paradigms appear more sensitive than others, but all face challenges associated with studying habits in the lab. Promising new approaches will need to be adopted and efforts made to capture real-world habits. Understanding which habits are problematic, when in illness and for whom they dominate, could make good on the promise of habit-focused treatments for AN.
习惯具有自动性且对结果不敏感，可能是神经性厌食症（AN）中适应不良行为持续存在的关键。本综述探讨了AN中习惯研究的现状，重点关注基于任务评估的见解。
研究结果表明，与习惯性和目标导向行为相关的额纹状体回路存在功能障碍，一些研究将神经紊乱与习惯测量或临床相关行为联系起来。使用自我报告一直报告AN中习惯性倾向增强，而利用实验范式的研究结果不一，且在AN中捕捉现实世界习惯的努力仍然有限。一些实验范式似乎比其他范式更敏感，但所有范式在实验室研究习惯时都面临挑战。需要采用有前景的新方法并努力捕捉现实世界的习惯。了解哪些习惯存在问题、在疾病的哪个阶段以及对哪些人来说这些习惯占主导地位，可能会实现针对AN的以习惯为重点的治疗的前景。
