奖励反应模式可能有助于饮食失调（EDs）的风险和维持，并且在ED诊断中，对不同实际和预期奖励的行为反应可能存在临床上有意义的异质性。我们使用了一种基于自我报告的对奖励相关刺激的反应倾向的经验方法来对ed个体进行分类。本研究利用气质与性格量表（Cloninger et al., 1993）子量表对跨诊断ED样本（N = 104）进行了潜在特征分析，对参与者的奖励反应进行了分类，包括对即时奖励的行为激活、对享乐奖励的行为激活（新奇寻求子量表）、对长期奖励的行为激活（持久性子量表）和对社会奖励的维持（奖励依赖子量表）。结果表明：(1)行为激活组（求新倾向升高，n = 62）；(b) Behavioral Persistence组（Persistence升高组，n = 42）。广义线性模型显示，在可能的AN、BN或OSFED组中，这些奖励反应谱的频率没有差异；然而，可能患有BED的个体更经常表现出行为激活特征（p = .041）。这些特征显示出相似的ED严重程度，但表现不同。在可能的ED诊断中，行为激活组报告了更多的暴饮暴食（p = 0.006, d = 0.32）和更高的bmi (p = 0.001, d = 0.57)；行为坚持组支持更大的驱动运动（p = 0.042, d = 0.33）。对新奇、即时奖励的激活与对长期奖励的坚持的分类与诊断中的不同症状有关，这可能支持特定奖励反应谱在ED现象学中的作用。
Reward response patterns may contribute to risk and maintenance of eating disorders (EDs), and there may be clinically meaningful heterogeneity in behavioral responses to different actual and anticipated rewards across ED diagnoses. We used an empirical approach to classify individuals with EDs based on self-reported tendencies for responding to reward-related stimuli. Latent profile analysis was conducted in a transdiagnostic ED sample (N = 104) using Temperament and Character Inventory (Cloninger et al., 1993) subscales to categorize participants on reward responses of behavioral activation towards immediate, hedonic rewards (Novelty Seeking subscale), persistence towards long-term rewards (Persistence subscale), and maintenance by social rewards (Reward Dependence subscale) rewards. Two profiles were identified: (1) Behavioral Activation group (elevated Novelty Seeking; n = 62); and (b) Behavioral Persistence group (elevated Persistence; n = 42). Generalized linear models comparing profiles showed that frequency of these reward response profiles did not differ in probable AN, BN, or OSFED groups; however, individuals with probable BED more often demonstrated the Behavioral Activation profile (p = .041). These profiles exhibited comparable ED severity, but different presentations. Across probable ED diagnoses, the Behavioral Activation group reported greater binge eating (p = .006, d = .32) and had higher BMIs (p = .001, d = .57); the Behavioral Persistence group endorsed greater driven exercise (p = .042, d = .33). Categorization by activation to novel, immediate rewards versus persistence towards long-term rewards was associated with different symptoms across diagnoses, potentially supporting the role of specific reward response profiles in ED phenomenology.
