The aim of this study was to identify naturally occurring groups of individuals experiencing binge eating (BE) symptoms based on their endorsement of varied functions of BE.
Adults (N = 646) with self-reported BE symptoms were examined using latent profile analysis to identify differentiated profiles based on eight established functions of BE. Profiles were also compared on measures of BE symptoms, eating disorder psychopathology, internal shame, body shame, psychological distress, adverse childhood experiences, and demographic variables.
A four-profile solution was selected balancing goodness-of-fit and interpretability. Profiles identified were Emotion Avoidance, Classic, Emotion Reactivity, and Complex, with profiles differing primarily on emotion- and trauma-related functions of BE, and varying on all associated characteristics examined, with the Complex profile showing the most adverse associations.
The identification of these distinct profiles suggests that individuals present with differentiated, inter-related patterns or reasons for BE. These clinically relevant profiles may inform binge-eating intervention choice and the targeting of specific maintenance factors within profiles. Further research is needed to examine the clinical utility of these profiles in informing the most suitable psychological treatment for an individual.
本研究旨在根据有暴饮暴食（BE）症状的个体对BE不同功能的认可程度，确定自然形成的群体。
对自我报告有BE症状的成年人（N = 646）进行潜在剖面分析，以根据BE的八项既定功能确定不同的剖面。还对各剖面在BE症状、饮食失调精神病理学、内在羞耻感、身体羞耻感、心理困扰、童年不良经历和人口统计学变量方面进行了比较。
选择了一个四剖面解决方案，兼顾了拟合优度和可解释性。确定的剖面为情绪回避型、经典型、情绪反应型和复杂型，各剖面主要在BE与情绪和创伤相关的功能上存在差异，在所检查的所有相关特征上也有所不同，复杂型剖面显示出最不利的关联。
这些不同剖面的确定表明，个体出现了不同的、相互关联的BE模式或原因。这些具有临床相关性的剖面可能为暴饮暴食干预选择以及针对剖面内特定维持因素提供信息。需要进一步研究以检验这些剖面在为个体提供最合适的心理治疗方面的临床效用。
