While previous research indicates a strong link between social anxiety and disordered eating, more research is needed in order to understand the mechanisms that underlie this relationship. Given that stress is often implicated in disordered eating, it was hypothesised that ones reaction to stress (i.e. stress reactivity) would mediate the relationship between social anxiety and disordered eating. Similarly, given that low self-esteem is commonly reported in both those with social anxiety and eating disorders, it was hypothesised that self-esteem would also mediate the relationship between social anxiety and disordered eating. In order to test this, an online survey measuring social anxiety, disordered eating, stress reactivity and self-esteem, was administered to 282 participants in the community, aged between 18 and 35years. Results showed that self-esteem and a reactivity to stress during social conflict - but not during negative social evaluations - partially mediated the relationship between social anxiety and disordered eating. These findings demonstrate that low self-esteem and interpersonal conflict are powerful mechanisms that can maintain eating disorder psychopathology in those who are socially anxious. This highlights the importance of ensuring that these mechanisms are sufficiently addressed in eating disorder prevention and treatment programs.
虽然先前的研究表明社交焦虑与饮食失调之间存在紧密联系，但仍需要更多研究来了解这种关系背后的机制。鉴于压力常与饮食失调有关，研究假设个体对压力的反应（即压力反应性）会介导社交焦虑与饮食失调之间的关系。同样，鉴于社交焦虑者和饮食失调者普遍都有低自尊的情况，研究假设自尊也会介导社交焦虑与饮食失调之间的关系。为了验证这一点，对社区中282名年龄在18至35岁之间的参与者进行了一项在线调查，该调查测量社交焦虑、饮食失调、压力反应性和自尊。结果显示，自尊以及社交冲突期间（而非负面社会评价期间）的压力反应性部分介导了社交焦虑与饮食失调之间的关系。这些发现表明，低自尊和人际冲突是导致社交焦虑者饮食失调心理病理学持续存在的重要机制。这凸显了在饮食失调预防和治疗项目中充分关注这些机制的重要性。
