Online data collection is becoming increasingly common and has some advantages compared to traditional paper-and-pencil formats, such as reducing loss of data, increasing participants' privacy, and decreasing the effect of social desirability. However, the validity and reliability of this administration format must be established before results can be considered acceptable. The aim of this study was to evaluate the validity, reliability, and equivalence of paper-and-pencil and online versions of the Weight Concerns Scale (WCS) when applied to Brazilian university students. A crossover design was used, and the Portuguese version of the WCS (in both paper-and-pencil and online formats) was completed by 100 college students. The results indicated adequate fit in both formats. The simultaneous fit of data for both groups was excellent, with strong invariance between models. Adequate convergent validity, internal consistency, and mean score equivalence of the WCS in both formats were observed. Thus, the WCS presented adequate reliability and validity in both administration formats, with equivalence/stability between answers.
在线数据收集正变得越来越普遍，与传统的纸笔形式相比有一些优势，比如减少数据丢失、增强参与者隐私以及降低社会期望效应。然而，在结果被认为可接受之前，必须确定这种管理形式的有效性和可靠性。本研究的目的是评估纸笔版和在线版体重关注量表（WCS）应用于巴西大学生时的有效性、可靠性和等效性。采用了交叉设计，100名大学生完成了葡萄牙语版的WCS（纸笔版和在线版）。结果表明两种形式都有足够的拟合度。两组数据的同时拟合非常出色，模型之间有很强的不变性。观察到两种形式的WCS都有足够的收敛效度、内部一致性和平均得分等效性。因此，WCS在两种管理形式中都表现出足够的可靠性和有效性，答案之间具有等效性/稳定性。
