Abstract

Objectives: Impulsivity has been linked to overeating and loss of control eating (LOCE), yet most adolescent research has focused on between-subjects (i.e., trait) impulsivity; thus, less is known about how within-subjects (i.e., state) impulsivity predicts overeating and LOCE. Given this gap, this study used ecological momentary assessment (EMA) to examine the construct validity of the four-item Momentary Impulsiveness Scale (MIS) in adolescents and the relationship between within- and between-subjects impulsivity and overeating and LOCE.

Methods: Seventy-four adolescents (M_age = 15.68) completed a 10-day EMA protocol, reporting impulsivity (measured with the MIS) and eating behaviours multiple times daily. Generalised linear mixed models were run examining associations between baseline impulsivity measures and EMA impulsivity and impulsivity, disaggregated into within- and between-subjects effects, as a prospective predictor of overeating and LOCE.

Results: Generally, baseline impulsivity measures predicted elevated EMA impulsivity. Also, higher within-subject impulsivity significantly predicted greater LOCE and higher between-subject impulsivity was significantly associated with greater overeating and LOCE.

Discussion: Analyses demonstrated concordance between baseline and EMA impulsivity measures in adolescents and suggested that state impulsivity impacts the perceived control over eating. Adolescent preventions/interventions that provide strategies to reduce or mitigate state impulsivity warrant further investigation (e.g., providing in-the-moment self-regulatory strategies when feeling impulsive).

青少年冲动、暴饮暴食和饮食失控的生态瞬时评估。

目的：冲动性与暴饮暴食和饮食失控（LOCE）有关，但大多数青少年研究都集中在受试者之间（即特质）冲动性；因此，对于主体内（即状态）冲动如何预测暴饮暴食和LOCE，我们知之甚少。鉴于这一空白，本研究采用生态瞬间评估（EMA）来检验青少年四项瞬间冲动量表（MIS）的结构效度，以及被试内部和被试之间的冲动、暴饮暴食和LOCE之间的关系。方法：74名青少年（Mage = 15.68）完成了为期10天的EMA方案，每天多次报告冲动（用MIS测量）和饮食行为。使用广义线性混合模型检查基线冲动性测量与EMA冲动性和冲动性之间的关联，将其分解为受试者内部和受试者之间的影响，作为暴饮暴食和LOCE的前瞻性预测因子。结果：一般来说，基线冲动性测量预测EMA冲动性升高。此外，较高的主体内冲动性显著预测较高的LOCE，较高的主体间冲动性与较高的暴饮暴食和LOCE显著相关。讨论：分析证明了基线和EMA冲动测量在青少年中的一致性，并表明状态冲动影响对饮食的感知控制。提供策略以减少或减轻状态冲动的青少年预防/干预措施值得进一步研究（例如，在感到冲动时提供即时自我调节策略）。

期刊介绍： European Eating Disorders Review publishes authoritative and accessible articles, from all over the world, which review or report original research that has implications for the treatment and care of people with eating disorders, and articles which report innovations and experience in the clinical management of eating disorders. The journal focuses on implications for best practice in diagnosis and treatment. The journal also provides a forum for discussion of the causes and prevention of eating disorders, and related health policy. The aims of the journal are to offer a channel of communication between researchers, practitioners, administrators and policymakers who need to report and understand developments in the field of eating disorders.
