Objective

Food addiction (FA) shows phenotypic and diagnostic overlap with eating disorders characterised by binge eating, though it is unknown how momentary processes driving binge-eating symptoms differ by FA. The present study examined the possible moderating influence of FA severity on momentary mechanisms underlying binge-eating symptomatology using ecological momentary assessment (EMA).

Method

Adults (N = 49, mean age = 34.9 ± 12.1, cis-gender female = 77.1%) who met criteria for FA and/or binge-eating disorder completed baseline measures including the Yale Food Addiction Scale (YFAS) followed by a 10-day EMA protocol. Generalised linear mixed models assessed main effects of YFAS, momentary antecedents (affect, impulsivity, food cue exposure, appetite, and eating expectancies) and two-way interactions between YFAS and within-person antecedents.

Results

FA severity moderated momentary associations between food cue exposure and subsequent binge-eating symptoms: the association was stronger among participants with lower but not higher YFAS scores. No other interactions were significant.

Conclusions

Some functional associations underlying binge-eating symptoms vary based on individuals' level of FA symptoms. Future research to further understand how observed associations may differ amongst diverse populations and over course of illness may also inform future prevention and interventions.

目的：食物成瘾（FA）与以暴饮暴食为特征的进食障碍在表型和诊断上存在重叠，但目前尚不清楚不同FA导致暴饮暴食症状的瞬间过程有何不同。本研究采用生态瞬间评估（EMA）方法，研究了FA严重程度对暴食症状的瞬间机制可能产生的调节作用：方法：符合FA和/或暴食症标准的成年人（N = 49，平均年龄 = 34.9 ± 12.1，顺性别女性 = 77.1%）完成基线测量，包括耶鲁食物成瘾量表（YFAS），然后完成为期10天的EMA方案。广义线性混合模型评估了YFAS的主效应、瞬间前因（情绪、冲动、食物线索暴露、食欲和进食预期）以及YFAS和人内前因之间的双向交互作用：FA严重程度调节了食物线索暴露与随后暴饮暴食症状之间的瞬间关联：在YFAS得分较低而非较高的参与者中，这种关联更强。其他交互作用均不显著：结论：暴食症状的某些功能性关联因个体的 FA 症状水平而异。未来的研究将进一步了解所观察到的关联在不同人群和不同病程中的差异，这也将为未来的预防和干预措施提供参考。

Introduction

Anorexia nervosa (AN) is characterised by limited remission rates and emotional dimensions are often neglected. Cognitive remediation and emotional skills training (CREST) protocol aims to address cognitive and emotional factors. This study evaluates the feasibility and effectiveness of a modified rolling-group CREST protocol in an inpatient setting.

Methods

Quasi-experimental design evaluated CREST protocol in a rehabilitation programme. A total of 116 females diagnosed with AN were included, of whom 63 were included in the CREST protocol and 53 in the standard rehabilitation treatment. Various standardized measures were employed to assess psychopathology. Data collection occurred longitudinally, before and after CREST implementation.

Results

No significant differences emerged between groups regarding changes in specific eating psychopathology. CREST group exhibited significant improvements in emotion regulation (p = 0.002) and social skills (p = 0.014), besides a reduction in alexithymia (p < 0.001) and cognitive rigidity (p = 0.013). Empathic features remained stable. Participants reported positive perceptions of the CREST intervention.

Discussion

The study highlights the potential benefits of integrating emotional training within multidisciplinary intensive treatment for AN. Results emphasise the importance of treatment protocol with more affective and hot-cognition-related interventions, beyond weight-related psychopathology. Implementing a rolling-group CREST protocol in an inpatient setting showed promise in enhancing the emotional abilities of AN patients.

简介神经性厌食症（AN）的特点是缓解率有限，而情感因素往往被忽视。认知矫正和情绪技能训练（CREST）方案旨在解决认知和情绪因素。本研究评估了改良的滚动组 CREST 方案在住院环境中的可行性和有效性：方法：采用准实验设计对康复计划中的 CREST 方案进行评估。共有116名女性被诊断为自闭症，其中63人接受了CREST方案，53人接受了标准康复治疗。研究采用了多种标准化测量方法来评估心理病理学。数据收集是在CREST实施前后纵向进行的：结果：各组在特定饮食心理病理学方面的变化无明显差异。CREST组在情绪调节（p = 0.002）和社交技能（p = 0.014）方面有明显改善，此外还减少了情感淡漠（p 讨论：本研究强调了将情绪训练纳入自闭症多学科强化治疗的潜在益处。研究结果强调，除了与体重相关的心理病理学之外，治疗方案还必须包含更多与情感和热认知相关的干预措施。在住院环境中实施滚动小组CREST方案有望提高AN患者的情绪能力。

Objective

Fasting for weight control is an under-studied behaviour implicated in eating disorders. However, little is known about what factors account for its onset and persistence.

Method

This study sought to identify risk and maintenance factors for fasting among 1025 women recruited through an eating disorder self-help platform who completed study measures at baseline and 6 month follow-up. Univariate and multivariate logistic regressions were performed to test which variables at baseline predicted the onset (vs. stably asymptomatic) and persistence (vs. remission) of fasting at follow-up.

Results

Univariate models showed that higher baseline overvaluation, dissatisfaction, fear of weight gain, generalised and social anxiety, depression, self-esteem deficits and eating disorder symptoms (inflexible eating rules, driven exercise) predicted greater likelihood of fasting onset. Only fear of weight gain and depressive symptoms remained significant in the multivariate model. Higher baseline overvaluation, fear of weight gain, driven exercise, inflexible eating rules, and depression predicted greater likelihood of fasting persistence in univariate models. An adherence to inflexible eating rules and overvaluation remained significant in the multivariate model.

Conclusion

Findings shed new light on factors that may account for the development and maintenance of fasting, which have implications for guiding effective interventions targeting this behaviour.

目的：为控制体重而禁食是与饮食失调有关的一种研究不足的行为。然而，人们对导致禁食开始和持续的因素知之甚少：本研究旨在确定通过饮食失调自助平台招募的 1025 名女性中禁食的风险和维持因素，这些女性在基线和 6 个月的随访中完成了研究措施。研究人员通过单变量和多变量逻辑回归来检验哪些基线变量可预测禁食的发生（与无症状）和随访时禁食的持续（与缓解）：单变量模型显示，基线高估、不满意、担心体重增加、普遍焦虑和社交焦虑、抑郁、自尊缺陷和饮食失调症状（饮食规则不灵活、强迫运动）越高，预示禁食发生的可能性越大。在多变量模型中，只有担心体重增加和抑郁症状仍然显著。在单变量模型中，较高的基线高估、对体重增加的恐惧、运动驱动、不灵活的饮食规则和抑郁症状预示着更有可能持续禁食。坚持不灵活的饮食规则和高估体重在多变量模型中仍有显著意义：研究结果揭示了可能导致禁食行为形成和维持的因素，这对指导针对禁食行为的有效干预具有重要意义。

Objective

Little is known about factors associated with treatment trajectory following brief paediatric admissions for children and young people (CYP) admitted for medical complications of their eating disorder (ED). This project aimed to identify possible factors and ways to improve the usefulness of paediatric admissions.

Method

Retrospective NHS data was analysed to explore differences between paediatric admissions followed by community-based care or inpatient psychiatric care. Twelve parents were interviewed to seek feedback about paediatric admissions.

Results

Patients who received subsequent inpatient psychiatric care were unwell for longer, had longer paediatric admissions and more crisis team input, were more likely to have had previous admissions, and had higher parent-reported anxiety and depression. However, the groups did not significantly differ in ED severity. The interviews identified recommendations for improving paediatric admissions, which included improving understanding of EDs, enhancing communication channels, and providing psychological support to parents.

Conclusions

Factors linked with illness severity (but not illness severity itself) appear to be associated with the difference between CYP either returning to community-based care or requiring more intensive psychiatric input. These factors may help clinicians understand who requires subsequent inpatient care, allowing clinicians to target more intensive support earlier and facilitate smoother transitions between services.

目的：人们对因饮食失调（ED）并发症而入院的儿童和青少年（CYP）在短暂入院后的治疗轨迹相关因素知之甚少。该项目旨在确定可能的因素以及提高儿科入院治疗效用的方法：方法：对国家医疗服务系统的回顾性数据进行分析，探讨儿科入院后接受社区护理或住院精神病护理之间的差异。对12名家长进行了访谈，以了解他们对儿科入院治疗的反馈意见：结果：随后接受精神科住院治疗的患者不适时间更长，儿科入院时间更长，危机处理小组的投入更多，更有可能曾入院治疗，家长报告的焦虑和抑郁程度更高。不过，两组患者在急诊室严重程度上并无明显差异。访谈提出了改善儿科入院情况的建议，包括增进对急诊室的了解、加强沟通渠道以及为家长提供心理支持：与病情严重程度相关的因素（而非病情严重程度本身）似乎与儿童青少年重返社区护理或需要更密集的精神科投入之间的差异有关。这些因素可能有助于临床医生了解哪些人需要后续的住院治疗，从而使临床医生能够更早地为他们提供更深入的支持，并促进服务之间的顺利过渡。

Objective

Research regarding the therapeutic application of psychedelics and psychedelic-assisted psychotherapy in the treatment of eating disorders (EDs) has begun to emerge. This systematic scoping review aimed to map and synthesise the existing evidence regarding the participant reported efficacy and perspectives concerning psychedelics in the treatment of EDs, and to identify significant research gaps.

Method

A systematic search was undertaken across several databases in accordance with Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews guidelines.

Results

1290 publications were identified, 1135 after duplicates removed, with 17 meeting full-eligibility criteria. Overall, findings suggested that most participants reported experiencing a meaningful reduction in their ED symptoms and having positive experiences or an openness to explore psychedelics as a treatment for ED symptoms, although some noted concerns of adverse effects and the importance of having psychological support to increase safety and efficacy.

Conclusions

While preliminary research suggests psychedelics and psychedelic-assisted psychotherapy may be a viable treatment option for ED symptoms, further research with more robust research designs is required to increase confidence in its efficacy, generalisability, and safety as a therapeutic medium.

目的：有关迷幻药和迷幻药辅助心理疗法在饮食失调症（EDs）治疗中的应用的研究已经开始出现。本系统性范围界定综述旨在绘制和综合现有证据，这些证据涉及参与者报告的迷幻剂在治疗饮食失调症方面的疗效和观点，并找出重要的研究缺口：方法：根据《系统综述和Meta分析的首选报告项目》（Preferred Reporting Items for Systematic Review and Meta-Analyses extension for Scoping Reviews）指南，在多个数据库中进行了系统检索：共发现 1290 篇出版物，去除重复内容后为 1135 篇，其中 17 篇符合完全合格标准。总体而言，研究结果表明，大多数参与者都报告说他们的性欲减退症状明显减轻，并有积极的体验或愿意探索将迷幻药作为治疗性欲减退症状的方法，但也有一些人指出了对不良反应的担忧以及获得心理支持以提高安全性和有效性的重要性：尽管初步研究表明，迷幻药和迷幻药辅助心理疗法可能是治疗ED症状的一种可行方法，但还需要进行更深入的研究，采用更稳健的研究设计，以增强人们对其作为一种治疗手段的疗效、普遍性和安全性的信心。

Objective

Although a significant number of professionals who provide eating disorder (ED) treatment have lived experience with an ED in the past, there is no consensus on whether these professionals should use these experiences in treatment. This review aims to evaluate current literature on recovered professionals with an ED past treating ED patients, unravelling advantages and disadvantages in treatment, the impact on professionals and their surroundings, and implications for practice.

Method

A systematic literature search was conducted which included 10 articles. We analysed qualitative data through a systematic synthesis. Strength of evidence was calculated for each subtheme.

Results

Three themes and 14 subthemes were divided into categories. The category ‘treatment (patient-professional interaction)’ was divided into: advantages, disadvantages and other implications for treatment. Additionally, the category ‘professionals themselves’ included subthemes that directly impact or relate to ED professionals: recovery as a non-linear process, the significant role of self-care and adverse feelings of professionals. Finally, the category ‘work settings’ included: company culture and training, supervision and professional development.

Discussion

Recovered ED professionals are a promising addition to ED treatment due to the enhanced expertise of the professional. However, attention should be paid to the risk of distorted boundaries between patient and professional.

目的：尽管很多提供饮食失调症（ED）治疗的专业人员过去都有ED的生活经历，但对于这些专业人员是否应该在治疗中利用这些经历，目前还没有达成共识。本综述旨在评估目前关于曾患有饮食失调症的康复专业人员治疗饮食失调症患者的文献，揭示治疗中的利弊、对专业人员及其周围环境的影响以及对实践的意义：方法：我们进行了系统的文献检索，其中包括 10 篇文章。我们通过系统综合分析了定性数据。对每个次主题计算了证据强度：结果：我们对三个主题和 14 个子主题进行了分类。治疗（患者与专业人员的互动）"类别分为：治疗的优点、缺点和其他影响。此外，"专业人员自身 "类别还包括直接影响或涉及 ED 专业人员的次主题：康复是一个非线性过程、自我护理的重要作用以及专业人员的负面情绪。最后，"工作环境 "类别包括：公司文化和培训、监督和专业发展：讨论：由于专业人员的专业知识得到了提高，ED 康复专业人员是对 ED 治疗的一种有前途的补充。然而，应注意患者与专业人员之间的界限可能会被扭曲。

European Eating Disorders Review

Objective

Eating disorders (EDs) are associated with elevated suicide. Low body mass index (BMI) and frequency of purging and binge eating represent severity criteria for EDs and distinguish full-threshold EDs from other specified feeding and eating disorders (OSFED). However, no work has taken a transdiagnostic approach to studying whether severity of these or other features is associated with suicidal ideation (SI) and attempts.

Method

We examined diagnostic status, ED features, and SI and attempts in a large, transdiagnostic, community sample of 257 women with EDs and 45 controls without a current or past ED in the United States using the EDs Examination interview and the Structured Clinical Interview for the DSM-5 (Diagnostic and Statistical Manual of Mental Disorders).

Results

SI and suicide attempts (SA) were elevated in OSFED compared to controls but did not differ between OSFED and full-threshold EDs. Higher BMI predicted increased SI. Number of purging methods, but not frequency, was related to history of SA. Binge episode frequency and size were not significant predictors.

Conclusions

OSFED presents with elevated SI and SA, and ED severity criteria that distinguish OSFED from full-threshold EDs do not predict SI or SA. Suicide risk assessments should be implemented universally across EDs in clinical practice.

目的：进食障碍（ED）与自杀率升高有关。低体重指数（BMI）以及清食和暴饮暴食的频率代表了进食障碍的严重程度标准，并将完全阈值进食障碍与其他特定进食和饮食障碍（OSFED）区分开来。然而，还没有研究采用跨诊断方法来研究这些特征或其他特征的严重程度是否与自杀意念（SI）和企图自杀有关：我们使用 EDs 检查访谈和 DSM-5（《精神疾病诊断与统计手册》）结构化临床访谈，对美国 257 名患有 ED 的女性和 45 名未患有 ED 的对照者进行了大规模、跨诊断的社区抽样调查，研究了她们的诊断状态、ED 特征、SI 和自杀企图：结果：与对照组相比，OSFED 的 SI 和自杀未遂（SA）率较高，但 OSFED 与完全阈值 ED 之间并无差异。体重指数越高，SI越高。清除方法的数量（而非频率）与 SA 史有关。暴饮暴食发作的频率和规模不是重要的预测因素：OSFED表现为SI和SA升高，而将OSFED与完全阈值ED区分开来的ED严重程度标准并不能预测SI或SA。在临床实践中，应在所有急诊室普遍实施自杀风险评估。

Objective

Anorexia nervosa (AN) has been associated with alterations in the processing of socio-emotional information, including impairments in the recognition of emotions in other people's faces. However, adolescents with AN might not show the impairments found in adult patients. The present study investigated facial emotion recognition in adolescents with AN, aiming to replicate our previous results of superior emotion recognition abilities in adolescents with AN compared to adolescents without mental disorders.

Method

Adolescent girls (12–18 years) with AN (n = 33) were compared to girls without mental disorders (n = 41). Participants completed one task requiring identification of emotions (happy, sad, afraid, angry, neutral) in faces and one control task.

Results

As expected, adolescents with AN showed superior emotion recognition, with higher accuracy rates specifically for afraid faces.

Conclusion

This is the first study replicating previous results on basic emotion recognition in adolescents with AN using (almost) the same methodology. The results suggest that, in contrast to adults, adolescents with AN do not show impairments in facial emotion recognition. The impairments may arise in the longer course of the illness, however, longitudinal studies are necessary to confirm this assumption.

目的：神经性厌食症（AN神经性厌食症（AN）与社会情绪信息处理的改变有关，包括对他人面部情绪的识别障碍。然而，患有神经性厌食症的青少年可能并不表现出成年患者的障碍。本研究调查了患有自闭症的青少年的面部情绪识别能力，旨在重复我们之前的研究结果，即与无精神障碍的青少年相比，患有自闭症的青少年的情绪识别能力更强：方法：将患有自闭症的少女（12-18 岁）（33 人）与无精神障碍的少女（41 人）进行比较。受试者完成一项要求识别面部情绪（快乐、悲伤、恐惧、愤怒、中性）的任务和一项对照任务：不出所料，患有自闭症的青少年在情绪识别方面表现突出，尤其是在识别害怕的面孔时准确率更高：这是首次使用（几乎）相同的方法，对患有自闭症的青少年的基本情绪识别结果进行重复研究。研究结果表明，与成人相比，患有自闭症的青少年在面部情绪识别方面并不存在障碍。然而，这种障碍可能会在较长的病程中出现，因此有必要进行纵向研究来证实这一假设。

Objective

Eating disorders (ED) have recently been studied from a network approach, conceptualising them as a complex system of interconnected variables, while highlighting the role of non-ED symptoms and personality dimensions. This study aims to explore the connections between personality and ED symptoms, identify central nodes, and compare the EDs network to a healthy control network.

Methods

We employed network analysis to examine the personality-ED symptom connections in 329 individuals with an ED diagnosis and 192 healthy controls. We estimated a regularised partial correlation network and the indices of centrality and bridge centrality to identify the most influential nodes for each group. Network differences between groups were also examined.

Results

Low Self-Directedness and high Harm avoidance emerged as central bridge nodes, displaying the strongest relationship with ED symptoms. Both networks differed in their global connectivity and structure, although no differences were found in bridge centrality and centrality indices.

Conclusions

These findings shed light on the role of personality dimensions, such as Self-Directedness and Harm Avoidance in the maintenance of ED psychopathology, supporting the transdiagnostic conceptualisation of ED. This study advances a deeper understanding of the complex interplay between personality dimensions and ED symptoms, offering potential directions for clinical interventions.

目的：饮食失调症（ED）最近已从网络的角度进行了研究，将其概念化为一个由相互关联的变量组成的复杂系统，同时强调了非ED症状和人格维度的作用。本研究旨在探索人格与 ED 症状之间的联系，确定中心节点，并将 ED 网络与健康对照网络进行比较：方法：我们采用网络分析法研究了 329 名被诊断为 ED 的患者和 192 名健康对照者的人格与 ED 症状之间的联系。我们估算了正则化部分相关网络以及中心性指数和桥中心性指数，以确定每个组别中最具影响力的节点。我们还研究了组间的网络差异：结果：低自我导向性和高伤害回避成为中心桥节点，与 ED 症状的关系最为密切。虽然在桥中心性和中心性指数方面没有发现差异，但这两个网络在整体连通性和结构方面存在差异：这些发现揭示了人格维度（如自我导向和伤害回避）在维持 ED 精神病理学中的作用，支持 ED 的跨诊断概念。这项研究加深了人们对人格维度与 ED 症状之间复杂的相互作用的理解，为临床干预提供了潜在的方向。

Objective

The study investigated interpersonal distance in patients with anorexia nervosa (AN), focussing on the role of other's facial expression and morphology, also assessing physiological and subjective responses.

Method

Twenty-nine patients with AN and 30 controls (CTL) were exposed to virtual characters either with an angry, neutral, or happy facial expression or with an overweight, normal-weight, or underweight morphology presented either in the near or far space while we recorded electrodermal activity. Participants had to judge their preferred interpersonal distance with the characters and rated them in terms of valence and arousal.

Results

Unlike CTL, patients with AN exhibited heightened electrodermal activity for morphological stimuli only, when presented in the near space. They also preferred larger and smaller interpersonal distances with overweight and underweight characters respectively, although rating both negatively. Finally, and similar to CTL, they preferred larger interpersonal distance with angry than neutral or happy characters.

Discussion

Although patients with AN exhibited behavioural response to emotional stimuli similar to CTL, they lacked corresponding physiological response, indicating emotional blunting towards emotional social stimuli. Moreover, they showed distinct behavioural and physiological adjustments in response to body shape, confirming the specific emotional significance attached to body shape.

目的：研究神经性厌食症（AN）患者的人际距离：本研究调查了神经性厌食症（AN）患者的人际距离，重点是他人面部表情和形态的作用，同时还评估了生理和主观反应：29名神经性厌食症患者和30名对照组（CTL）在我们记录皮电活动的同时，被试在近处或远处接触到面部表情为愤怒、中性或快乐，或形态为超重、正常体重或体重不足的虚拟人物。受试者必须判断自己喜欢与这些人物的人际距离，并对他们的情绪和唤醒程度进行评分：结果：与 CTL 不同的是，当形态刺激出现在近处空间时，AN 患者仅对形态刺激表现出更强的皮电活动。此外，他们还喜欢与体重过重和体重过轻的角色分别保持较大和较小的人际距离，但对这两种角色的评价都是负面的。最后，与 CTL 相似，他们更喜欢与愤怒的人物保持较大的人际距离，而不是中性或快乐的人物：讨论：虽然自闭症患者对情绪刺激的行为反应与 CTL 相似，但他们缺乏相应的生理反应，这表明他们对情绪性社会刺激的情感迟钝。此外，他们对身体形状的行为和生理反应均有不同程度的调整，证实身体形状具有特定的情绪意义。
