现有的评估限制饮食的措施将有问题的限制做法和健康的限制做法混为一谈,并在没有减少卡路里摄入量的情况下感觉到限制。在这项研究中,我们设计并测试了一种单一项目筛查的效用,即饮食限制筛查(DRS),以评估有问题的限制。94人完成了DRS和评估进食障碍症状、关注和仪式的测量。参与者可以随意获得一份单品测试小吃。进行线性回归,以评估在控制相关协变量和常用的约束量表后,DRS是否可以预测进食障碍症状和零食摄入量。DRS显著预测进食障碍症状(p<.001)、关注(p<.001)和仪式(p=.001),以及零食摄入量(p=.017)以上的协变量和现有的约束等级。与现有措施相比,DRS可能会在预测有问题的饮食限制方面提供额外的实用价值,并且由于简明和负担较低而有益。
Existing measures to assess restrictive eating conflate both problematic and healthy restrictive practices, and perceived restriction without reduced caloric intake. In this study, we devised and tested the utility of a single-item screener, the Dietary Restriction Screener (DRS), to assess problematic restriction. 94 individuals completed the DRS and measures assessing eating disorder symptoms, preoccupations, and rituals. Participants were given access to an ad libitum single-item test snack. Linear regressions were conducted to evaluate whether the DRS predicted eating disorder symptoms and snack intake after controlling for relevant covariates and a commonly-used restraint scale. The DRS significantly predicted eating disorder symptoms (p < .001), preoccupations (p < .001), and rituals (p = .001), and snack intake (p = .017) above covariates and an existing restraint scale. The DRS may offer added utility in predicting problematic dietary restriction over existing measures, and is beneficial due to brevity and low burden.
