Picky eating describes a pattern of eating characterised by a narrow dietary range with rejection of both novel and familiar foods. Research has suggested that picky eating in adulthood is associated with several negative psychosocial outcomes including impaired quality of life. This research aimed to build and test a model explaining the relationship between picky eating and quality of life. 230 participants were recruited via online support forums for picky eating, and an undergraduate research participation scheme. Participants completed self-report measures of picky eating, sensory sensitivity, disgust, anxiety, fear of negative evaluation and eating related quality of life. Regression analysis indicated that picky eating, disgust sensitivity, anxiety, and fear of negative evaluation were all associated with impaired eating-related quality of life. A theoretical model was then devised which aimed to explain the interactions between these factors, and Path Analysis indicated that this model was a good fit for the data. This Safety in Picky Eating and Quality of life (SPEQ) model suggests that threat perception and the drive for safety underlies the relationship between picky eating and impaired quality of life. The SPEQ model provides a preliminary basis for understanding how picky eating impacts quality of life in adulthood.
挑食描述的是一种饮食模式，其特点是饮食范围狭窄，既拒绝新食物也拒绝熟悉的食物。研究表明，成年人挑食与一些负面的社会心理结果有关，包括生活质量受损。这项研究旨在建立和检验一个解释挑食与生活质量之间关系的模型。230 名参与者通过在线挑食支持论坛和本科生研究参与计划招募。参与者完成了关于挑食、感官敏感度、厌恶、焦虑、对负面评价的恐惧和与饮食相关的生活质量的自我报告衡量。回归分析表明，挑食、厌恶敏感度、焦虑和对负面评价的恐惧都与饮食相关的生活质量受损有关。然后设计了一个理论模型，旨在解释这些因素之间的相互作用，路径分析表明该模型非常适合数据。这个挑食与生活质量安全模型（SPEQ）表明，威胁感知和安全驱动是挑食和生活质量受损之间关系的基础。SPEQ 模型为理解挑食如何影响成年人的生活质量提供了初步依据。
