Nonhomeostatic eating is a complex (presumably) multidimensional construct associated with negative health outcomes. However, little research has examined the latent structure of nonhomeostatic eating processes, interrelationships among nonhomeostatic eating constructs, and differential associations between nonhomeostatic eating constructs and external correlates. This study adopted a construct validation approach to investigate these research questions in a large sample of undergraduate women and men (N = 998; 54.6% female). Exploratory and confirmatory factor analyses were conducted on items from 8 measures representing numerous nonhomeostatic eating process constructs (e.g., binge eating, loss of control [LOC] over eating, "food addiction"). The 7-factor retained solution included the following: (1) emotional eating, (2) external eating, (3) LOC over eating, (4) overeating, (5) distress over nonhomeostatic eating, (6) hedonic hunger, and (7) food addiction. LOC over eating was the nonhomeostatic eating factor most strongly related to other factors (M rs = .71 and .65 in women and men, respectively). Factor score multiple regressions conducted separately by sex indicated that distress over nonhomeostatic eating was related to body mass index, depressive symptoms, and eating-related clinical impairment in both women and men. In women, food addiction demonstrated unique associations with depressive symptoms, emotion dysregulation, and clinical impairment, whereas overeating uniquely predicted these outcomes in men. This is the first comprehensive analysis of the latent structure of nonhomeostatic eating processes and associations with external correlates, and results suggest that LOC over eating, distress over nonhomeostatic eating, food addiction (in women), and overeating (in men) exhibited the strongest relations with psychosocial impairment.

非稳态进食是一种与负面健康结果相关的复杂（推测）多维结构。然而，很少有研究检验非稳态进食过程的潜在结构、非稳态进食结构之间的相互关系，以及非稳态进食结构与外部相关因素之间的差异关联。本研究采用结构验证方法，在一个大型的本科生女性和男性样本中（N=998；女性占 54.6%）研究了这些问题。对来自 8 项测量的项目进行了探索性和验证性因素分析，这些测量代表了许多非稳态进食过程的结构（例如，暴食、进食失控[LOC]、“食物成瘾”）。保留的 7 因素解决方案包括：（1）情绪性进食，（2）外部进食，（3）LOC 进食，（4）暴饮暴食，（5）非稳态进食引起的苦恼，（6）享乐性饥饿，和（7）食物成瘾。LOC 进食是与其他因素相关性最强的非稳态进食因素（女性和男性的 M rs 值分别为.71 和.65）。按性别分别进行的因子得分多元回归表明，非稳态进食引起的苦恼与身体质量指数、抑郁症状和进食相关的临床障碍在女性和男性中都有关联。在女性中，食物成瘾与抑郁症状、情绪失调和临床障碍有独特的关联，而暴饮暴食在男性中则对这些结果有独特的预测作用。这是对非稳态进食过程的潜在结构和与外部相关因素的关联的首次全面分析，结果表明，LOC 进食、非稳态进食引起的苦恼、食物成瘾（女性）和暴饮暴食（男性）与心理社会障碍的关系最强。（PsycINFO 数据库记录（c）2019 APA，保留所有权利）。
