本研究的两个目的是：（1）确定肥胖个体的日常负面情绪模式（NA）;（2）确定日常情绪模式是否与暴饮暴食而不失控（仅OE），饮食失控而不暴饮暴食（仅LOC）和暴饮暴食（BE）事件有关。50名肥胖（BMI=40.3 +/- 08.5）成年人（84.0%女性）完成了为期两周的生态瞬时评估方案，在此期间，他们完成了NA评估，并指出他们的饮食事件是否具有OE和/或ESTA特征。潜在增长混合模型（LGMM）被用来确定NA的日常轨迹。GEE分析被用来确定是否每天的影响轨迹有差异相关的频率OE，LOC，只有BE发作。LGMM分析确定了NA的9个独特轨迹。显着更高的频率发生的OE，只有BE事件的特点是高或不断增加的NA水平的日子。各组之间仅LOC发作的频率无显著差异。这些数据表明，NA可能作为一个先行词，以OE只有和BE事件，并针对“问题的影响天”可能会减少肥胖个体的OE只有和BE事件的发生。(C)2013爱思唯尔爱尔兰有限公司保留所有权利。
The two objectives of the current study were: (1) to identify daily patterns of negative affect (NA) in obese individuals; and (2) to determine whether daily affect patterns were related to overeating without loss of control (OE-only), loss of control eating without overeating (LOC-only), and binge eating (BE) episodes. Fifty obese (BMI=40.3 +/- 08.5) adults (84.0% female) completed a two-week ecological momentary assessment protocol during which they completed assessments of NA and indicated whether their eating episodes were characterized by OE and/or LOC. Latent growth mixture modeling (LGMM) was used to identify daily trajectories of NA. GEE analysis was used to determine whether daily affect trajectories were differentially related to the frequency of OE-only, LOC-only, and BE episodes. The LGMM analyses identified nine unique trajectories of NA. Significantly higher frequencies of OE-only and BE episodes occurred on days characterized by high or increasing levels of NA. There were no significant differences between classes for the frequency of LOC-only episodes. These data suggest that NA may act as an antecedent to OE-only and BE episodes and that targeting "problematic affect days" may reduce the occurrence of OE-only and BE episodes among obese individuals.
