The extant literature on picky eating focuses on children, leaving adults understudied. A sparse and mixed evidence base suggests relationships exist between picky eating and disordered eating in adults. The present study furthered this research by examining shared negative psychological correlates as moderators that may strengthen relationships between picky eating and disordered eating in undergraduate students. Participants (N = 509; 76.3% female) completed a cross-sectional survey assessing picky eating (Adult Picky Eating Questionnaire), disordered eating (Binge Eating Scale and Eating Disorder Examination-Questionnaire), and negative psychological correlates including anxiety, depression, and stress (Depression, Anxiety and Stress Scale - 21 Items), inflexible eating (Inflexible Eating Questionnaire), obsessive compulsive disorder (Short Obsessive Compulsive Disorder Screener), and social eating anxiety (adapted Social Phobia Scale) symptoms. Positive relationships were observed between picky eating and binge eating, dietary restraint, eating concerns, overall eating pathology, and all negative psychological correlates. Moderation analyses examined if negative psychological correlates strengthened relationships between picky eating and disordered eating. Higher inflexible eating and anxiety and stress symptoms interacted with higher picky eating in relation to disordered eating, specifically eating concerns. Interactions between picky eating and negative psychological correlates did not explain variance in binge eating, dietary restraint, and overall eating pathology. Findings complement research demonstrating overlap between picky eating and disordered eating and highlight specific negative psychological correlates that may strengthen relationships between picky eating and disordered eating. Researchers and clinicians interested in concurrent picky eating and disordered eating should consider these negative psychological correlates given their potential to worsen disordered eating.

现有的关于挑食的文献主要集中在儿童身上，而对成年人的研究不足。稀疏和混杂的证据基础表明，成年人的挑食和饮食失调之间存在联系。本研究通过检查共享的负性心理相关因素作为主持人，进一步加强了这项研究，这些因素可能会加强大学生的挑食和饮食失调之间的关系。参加人数 = 509; 76.3％的女性）完成了一项横断面调查，评估了挑剔饮食（成人挑食饮食问卷），饮食失调（必应饮食量表和进食障碍检查问卷）以及负面的心理相关因素，包括焦虑，抑郁和压力（抑郁，焦虑和压力量表-21个项目），不灵活饮食（不灵活饮食问卷），强迫症（短期强迫症筛查者）和社交进食焦虑症（适应性社交恐惧症评分）。在挑食和暴饮暴食，节制饮食，关注饮食，总体饮食病理以及所有负面心理关联之间观察到正相关。适度分析检查了负面心理是否与挑食和饮食失调之间的关系加强有关。与饮食失调（特别是饮食问题）相关，较高的僵硬饮食，焦虑和压力症状与较高的挑剔饮食相互作用。挑食与负性心理相关因素之间的相互作用不能解释暴饮暴食，饮食节制和整体进食病理的差异。结果补充了表明挑食与饮食失调之间重叠的研究，并强调了特定的负面心理相关性，这可能加强挑食与饮食失调之间的关系。对同时挑剔饮食和饮食失调感兴趣的研究人员和临床医生应考虑到这些负面的心理关联，因为它们有可能加剧饮食失调。特别是饮食方面的顾虑。挑食与负性心理相关因素之间的相互作用不能解释暴饮暴食，饮食节制和整体进食病理的差异。这些发现补充了表明挑食与饮食失调之间重叠的研究，并强调了特定的负面心理关联，可能会增强挑食与饮食失调之间的关系。对同时挑剔饮食和饮食失调感兴趣的研究人员和临床医生应考虑到这些负面的心理关联，因为它们有可能加剧饮食失调。特别是饮食方面的顾虑。挑食与负性心理相关因素之间的相互作用不能解释暴饮暴食，饮食节制和整体进食病理的差异。这些发现补充了表明挑食与饮食失调之间重叠的研究，并强调了特定的负面心理关联，可能会增强挑食与饮食失调之间的关系。对同时挑剔饮食和饮食失调感兴趣的研究人员和临床医生应考虑到这些负面的心理关联，因为它们有可能加剧饮食失调。这些发现补充了表明挑食与饮食失调之间重叠的研究，并强调了特定的负面心理关联，可能会增强挑食与饮食失调之间的关系。对同时挑剔饮食和饮食失调感兴趣的研究人员和临床医生应考虑到这些负面的心理关联，因为它们有可能加剧饮食失调。这些发现补充了表明挑食与饮食失调之间重叠的研究，并强调了特定的负面心理关联，可能会增强挑食与饮食失调之间的关系。对同时挑食和饮食失调感兴趣的研究人员和临床医生应考虑到这些负面的心理关联，因为它们可能使饮食失调恶化。
