Abstract

Item response tree (IRTree) approaches have received increasing attention in the response style literature due to their capability to partial out response style latent traits from content-related latent traits by considering separate decisions for agreement and level of agreement. Additionally, it has shown that the functioning of the intensity of agreement decision may depend upon the agreement decision with an item, so that the item parameters and person parameters may differ by direction of agreement; when the parameters across direction are the same, this is called directional invariance. Furthermore, for non-cognitive psychological constructs, it has been argued that the response process may be best described as following an unfolding process. In this study, a family of IRTree models to handle unfolding responses with the agreement decision following the hyperbolic cosine model and the intensity of agreement decision following a graded response model is investigated. This model family also allows for investigation of item- and person-level directional invariance. A simulation study is conducted to evaluate parameter recovery; model parameters are estimated with a fully Bayesian approach using JAGS (Just Another Gibbs Sampler). The proposed modeling scheme is demonstrated with two data examples with multiple model comparisons allowing for varying levels of directional invariance and unfolding versus dominance processes. An approach to visualizing the final model item response functioning is also developed. The article closes with a short discussion about the results.
研究项目反应树模型中极端反应风格和基于特质的展开反应的方向不变性
项目反应树(IRTree)方法通过考虑不同的同意决定和同意程度决定,能够从内容相关的潜在特质中分离出反应风格潜在特质,因此在反应风格文献中受到越来越多的关注。此外,研究表明,同意强度决定的功能可能取决于对项目的同意决定,因此项目参数和人的参数可能因同意方向的不同而不同;当不同方向的参数相同时,这被称为方向不变性。此外,对于非认知性心理建构而言,有人认为最好将反应过程描述为一个展开过程。在本研究中,我们研究了一个 IRTree 模型系列来处理展开式反应,其中同意决定采用双曲余弦模型,同意强度决定采用分级反应模型。该模型系列还可用于研究项目和个人层面的方向不变性。为评估参数恢复情况,进行了一项模拟研究;使用 JAGS(Just Another Gibbs Sampler,另一种吉布斯采样器)以完全贝叶斯方法估算模型参数。建议的建模方案通过两个数据示例进行了演示,并对多个模型进行了比较,以考虑不同程度的方向不变性和展开过程与优势过程。文章还提出了一种可视化最终模型项目反应功能的方法。文章最后对结果进行了简短讨论。
