We propose the use of balanced item parcels to account for method effects caused by acquiescent responding. The use of balanced parcels avoids the need to model method effects explicitly and results in a parsimonious specification of measurement and full structural equation models in the presence of unwanted method effects, particularly when a scale consists of a relatively large number of items. Balanced item parcels are sums or averages of individual items consisting of an equal number of regular and reversed items measuring the same construct. When regular and reversed items are combined into parcels, method effects cancel out (assuming that the method effects affecting the regular and reversed items in a parcel are equal in magnitude), and model fit and parameter estimates will no longer be negatively affected by acquiescent responding. We discuss why balanced item parceling works and when it is likely to prove beneficial, and we present a step-by-step procedure explaining how to use balanced item parceling in practice. We also report a brief hypothetical example to illustrate the proposed approach.

在结构方程模型中使用平衡项包裹来抵消默认偏差

我们建议使用平衡物料包来解决默认响应引起的方法影响。平衡宗地的使用避免了对方法效果进行显式建模的需要,并且在存在不希望的方法效果的情况下(特别是当标尺由相对大量的项目组成时)会导致对测量和完整结构方程模型的简化说明。平衡物料包是单个物料的总和或平均值,由相等数量的常规和反转物料组成,它们测量同一结构。将常规项目和逆向项目合并为包裹时,方法效果会抵消(假设影响包裹中常规项目和逆向项目的方法效果的大小相等),并且模型拟合和参数估计将不再受到默认响应的负面影响。我们讨论了为什么平衡项目包裹有效以及何时可能证明是有益的,并且我们给出了逐步的过程,解释了如何在实践中使用平衡项目包裹。我们还报告了一个简短的假设示例来说明所提出的方法。
