进食障碍（ED）与显著的心理和身体共病相关，青春期是ED发展的特别高风险时期。冲动性（即，很少有意识的判断或预先考虑）并影响反应性（即，对紧张性刺激作出反应的负面情绪的变化）被假设为促成了狂欢/净化艾德病理学的发展。目前的研究是第一次检查的前瞻性冲动和情感反应之间的关系，作为青少年随着时间的推移发展的艾德态度的预测。206名青少年参加了一项纵向研究，检查精神病理学的发展。艾德的态度，每年通过大学饮食失调屏幕进行评估，为期6年。基线冲动和情感反应也进行了评估。情感反应性、冲动性和它们之间的相互作用作为艾德态度随时间变化的基线预测因子，使用潜在增长模型进行了研究。潜在增长模型的结果表明，艾德态度随着时间的推移而增加。冲动性和情感反应之间的相互作用显着预测的斜率艾德态度，这样的冲动性和艾德态度之间的关系是最强的那些水平升高的情感反应。研究结果表明，更高水平的情感反应性和冲动性的发展艾德态度的青少年的关键危险因素。后续的研究应该检查情感反应和冲动之间的关系，在预测客观测量的艾德行为，除了艾德态度。进一步的研究可能暗示情感反应性和冲动性是早期干预预防青少年艾德症状发作的重要目标。
Eating disorders (EDs) are associated with significant psychological and physical comorbidities, and adolescence is a particularly high-risk time for the development of EDs. Impulsivity (i.e., acting with little conscious judgment or forethought) and affect reactivity (i.e., changes in negative affect in response to a stressor) are hypothesized to contribute to the development of binge/purge ED pathology. The current study is the first to examine the prospective relationships between impulsivity and affect reactivity as predictors of the development of ED attitudes in adolescents over time. Two hundred six adolescents participated in a longitudinal study examining the development of psychopathology. ED attitudes were assessed via the College Eating Disorders Screen annually for 6 years. Baseline impulsivity and affect reactivity were also assessed. Affect reactivity, impulsivity, and their interaction were examined as baseline predictors of changes in ED attitudes over time using latent growth modeling. Results of latent growth modeling indicated that ED attitudes increased over time. The interaction between impulsivity and affect reactivity significantly predicted the slope of ED attitudes, such that the relationship between impulsivity and ED attitudes was strongest for those with elevated levels of affect reactivity. Findings suggest that greater levels of affect reactivity and impulsivity are key risk factors for the development of ED attitudes in adolescents. Subsequent research should examine the relation between affect reactivity and impulsivity in predicting objectively measured ED behaviors, in addition to ED attitudes. Further investigation may implicate affect reactivity and impulsivity as important targets for early intervention to prevent onset of ED symptoms in adolescents.
