目标:了解早期自适应模式,认知灵活性,和情绪调节影响饮食失调(ED)症状,诊断亚型之间的差异对优化治疗至关重要。当前的研究调查了自我报告ED诊断和健康对照的个体中这些变量与ED症状学之间的关系。
方法:1576个在线调查响应的数据集产生了神经性厌食症的子样本(n=155),神经性贪食症(n=55),暴食症(n=33),其他特定的进食或进食障碍(n=93),和健康参与者(n=505)。分层线性回归分析包括饮食失调检查问卷6.0全局得分作为因变量;年轻积极模式问卷,情绪调节问卷,和认知灵活性库存子量表得分作为自变量;和人口测量作为协变量。
结果:ED亚组的显著预测因子数量差异很大。在神经性厌食症中,神经性贪食症,和健康的子样本,适应性模式自我同情和现实期望与较低的ED症状严重程度相关。相比之下,年龄和体重指数是暴食症的最强预测因子,而表达抑制(情绪调节问卷的子量表)是其他特定喂养或进食障碍的最强预测因子。
结论:早期自适应模式,认知灵活性,情绪调节因ED亚型而异,这表明需要有针对性的治疗来破坏ED精神病理学的自我强化周期。需要进行未来的研究,以调查早期自适应模式如何预测诊断亚型的治疗反应或与之相关。
方法:四级,从有或没有干预的多个时间序列中获得的证据,比如案例研究。
OBJECTIVE: Understanding how early adaptive schemas, cognitive flexibility, and emotional regulation influence eating disorder (ED) symptoms, and whether this differs across diagnostic subtypes is critical to optimising treatment. The current study investigated the relationship between these variables and ED symptomology in individuals self-reporting an ED diagnosis and healthy controls.
METHODS: A dataset of 1576 online survey responses yielded subsamples for anorexia nervosa (n = 155), bulimia nervosa (n = 55), binge eating disorder (n = 33), other specified feeding or eating disorder (n = 93), and healthy participants (n = 505). The hierarchical linear regression analysis included Eating Disorder Examination Questionnaire 6.0 Global Score as the dependent variable; Young Positive Schema Questionnaire, Emotional Regulation Questionnaire, and Cognitive Flexibility Inventory subscale scores as the independent variables; and demographic measures as the covariates.
RESULTS: The number of significant predictors varied considerably by ED sub-group. Amongst the anorexia nervosa, bulimia nervosa, and healthy subsamples, the adaptive schema Self-Compassion and Realistic Expectations was associated with lower ED symptom severity. In comparison, age and body mass index were the strongest predictors for binge eating disorder, whilst the Expressive Suppression (a subscale of the Emotional Regulation Questionnaire) was the strongest predictor for other specified feeding or eating disorders.
CONCLUSIONS: Early adaptive schemas, cognitive flexibility, and emotional regulation vary across ED subtype, suggesting the need for tailored treatment that disrupts the self-reinforcing cycle of ED psychopathology. Future research investigating how early adaptive schemas may predict or be associated with treatment response across diagnostic subtypes is needed.
METHODS: Level IV, evidence obtained from multiple time-series with or without the intervention, such as case studies.
