Abstract

Instagram is a popular social media platform with two billion active users every month. Despite its entertainment and social benefits, research has associated Instagram use with adverse mental and physical health outcomes. Recently, Instagram use has been associated with the maladaptive eating practice, orthorexia nervosa. Orthorexia nervosa refers to an unhealthy pre-occupation with the quality of food, rather than quantity, and has been associated with the prolific ‘clean eating’ movement trending on Instagram. The aim of the present study was to examine how Instagram engagement relates to symptoms of orthorexia nervosa, and whether one's contingent sense of self may help explain this relationship. Specifically, the study investigated if ‘nonattachment to self’, which indicates a more flexible and less contingent relationship with self-related thoughts and feelings, may mediate the relationship between Instagram engagement and orthorexia nervosa. Results from a cross-sectional study of 299 Australian undergraduate students (48 male, 247 female, 4 nonbinary) aged 18 to 84 (M = 29.57, SD = 11.91) revealed higher levels of Instagram engagement were associated with higher levels of orthorexia nervosa symptoms and a more rigid and fixed self-concept. Furthermore, nonattachment to self was found to mediate the relationship between Instagram engagement and orthorexia nervosa. The findings suggest a positive relationship between Instagram engagement and orthorexia nervosa symptoms, and that this relationship is partially attributed to the extent to which individuals fixate on their self-concept needing to be a certain way.

不依恋自我在澳大利亚大学生Instagram参与与正食症之间的关系中起中介作用。

Instagram是一个流行的社交媒体平台，每月有20亿活跃用户。尽管Instagram有娱乐和社交方面的好处，但研究表明，使用Instagram会对身心健康产生不利影响。最近，Instagram的使用与不适应饮食习惯（神经性厌食症）联系在一起。神经性厌食症指的是对食物质量的不健康关注，而不是对食物数量的关注，这与Instagram上流行的“清洁饮食”运动有关。本研究的目的是研究Instagram的使用与神经性厌食症的症状之间的关系，以及一个人的偶然自我意识是否有助于解释这种关系。具体来说，该研究调查了“不依恋自我”是否可能调解Instagram参与和神经性厌食症之间的关系。“不依恋自我”表明，与自我相关的思想和感受之间的关系更灵活、更少偶然。一项针对299名年龄在18至84岁的澳大利亚本科生（48名男性，247名女性，4名非二元性别）的横断研究（M = 29.57, SD = 11.91）的结果显示，较高水平的Instagram参与度与较高水平的神经性厌食症症状和更严格和固定的自我概念相关。此外，对自我的不依恋在Instagram参与与神经性厌食症之间起中介作用。研究结果表明，参与Instagram和神经性厌食症症状之间存在正相关关系，这种关系部分归因于个人对自己需要某种方式的自我概念的关注程度。

期刊介绍： Appetite is an international research journal specializing in cultural, social, psychological, sensory and physiological influences on the selection and intake of foods and drinks. It covers normal and disordered eating and drinking and welcomes studies of both human and non-human animal behaviour toward food. Appetite publishes research reports, reviews and commentaries. Thematic special issues appear regularly. From time to time the journal carries abstracts from professional meetings. Submissions to Appetite are expected to be based primarily on observations directly related to the selection and intake of foods and drinks; papers that are primarily focused on topics such as nutrition or obesity will not be considered unless they specifically make a novel scientific contribution to the understanding of appetite in line with the journal's aims and scope.
