Previous research demonstrating emotional influences on eating and weight suggest that emotionally expressive writing may have a significant impact on reducing risk of eating pathology. This study examined the effects of writing about Intensely Positive Experiences on weight and disordered eating during a naturalistic stressor. Seventy-one female students completed an expressive or a control writing task before a period of exams. Both groups were compared on BMI (kg/m) and the Eating Disorder Examination - Questionnaire (EDE-Q) before the writing task and at 8-week follow-up. A number of secondary analyses were also examined (to identify potential mediators) including measures of attachment, social rank, self-criticism and self-reassurance, stress and mood. There was a significant effect of intervention on changes in the subscales of the EDE-Q ( = .03). Specifically, expressive writers significantly reduced their dietary restraint while those in the control group did not. There was no significant effect of the intervention on changes in BMI or the other subscales of the EDE-Q (Eating, Weight and Shape Concern). There was also no effect of writing on any of the potential mediators in the secondary analyses. Emotionally expressive writing may reduce the risk of dietary restraint in women but these findings should be accepted with caution. It is a simple and light touch intervention that has the potential to be widely applied. However, it remains for future research to replicate these results and to identify the mechanisms of action.
先前的研究表明情绪对饮食和体重有影响，这表明情感表达性写作可能对降低饮食病理学风险有显著影响。本研究考察了在自然应激源期间书写强烈积极体验对体重和饮食失调的影响。71名女学生在考试前完成了表达性写作或对照写作任务。在写作任务前和8周随访时，对两组的体重指数（kg/m）和饮食失调检查问卷（EDE-Q）进行了比较。还进行了一些次要分析（以确定潜在的中介因素），包括依恋、社会地位、自我批评和自我安慰、压力和情绪的测量。干预对EDE-Q分量表的变化有显著影响（=0.03）。具体而言，表达性写作的参与者显著降低了饮食限制，而对照组则没有。干预对体重指数或EDE-Q的其他分量表（饮食、体重和体型关注）的变化没有显著影响。写作对次要分析中的任何潜在中介因素也没有影响。情感表达性写作可能会降低女性饮食限制的风险，但这些发现应谨慎接受。这是一种简单且影响较小的干预措施，有可能被广泛应用。然而，仍需未来的研究来复制这些结果并确定其作用机制。
