摘要
结构方程建模(SEM)是一种数据分析方法,被广泛应用于商业传播研究以及其他许多领域的研究中,当学者们需要检验具有多种结果、相互作用或跨不同情况操作的复杂模型时,就会用到这种方法。然而,迄今为止,研究人员不得不在使用基于协方差的 SEM 和基于复合的 SEM 之间做出选择,前者需要处理收敛问题,后者则面临严重的方法论问题。本文介绍了一种通过 PLSF-SEM 将这两种 SEM 的优势结合起来的方法。通过利用这种新颖的方法,实证研究人员可以采用传统上在基于协方差的 SEM 中使用的几种相同的检验方法,以及依赖于潜在变量估计值的新检验方法,简洁明了,学术性强。PLSF-SEM 建立在偏最小二乘法(PLS)算法的基础上,以生成相关保留因子;F 指的是它是基于因子的,而不是基于综合的。本文介绍了在商业交流研究中使用 PLSF-SEM 的入门方法,该方法基于一个受语言理论启发的示例模型,并使用 WarpPLS 软件对模拟数据进行了分析。
Methods Showcase—Using PLSF-SEM in Business Communication Research
Structural equation modeling (SEM) is a data analysis method that is widely used in business communication research, as well as research in many other fields, when scholars need to test complex models with multiple outcomes, interactions, or operations across different situations. To date, however, researchers have had to choose between using covariance-based SEM, and dealing with convergence problems; or composite-based SEM, and facing serious methodological issues. This article describes a way to combine strong aspects of both SEM types through PLSF-SEM. By utilizing this novel method, empirical researchers can employ several of the same tests traditionally used in covariance-based SEM, as well as new tests that rely on latent variable estimates, in a succinct and scholarly way. PLSF-SEM builds on partial least squares (PLS) algorithms to generate correlation-preserving factors; the F refers to it being factor-based, as opposed to composite-based. A primer on the use of PLSF-SEM in business communication research is provided, based on an illustrative model inspired by motivating language theory, and where simulated data was analyzed with the software WarpPLS.
期刊介绍:
The International Journal of Business Communication (IJBC) publishes manuscripts that contribute to knowledge and theory of business communication as a distinct, multifaceted field approached through the administrative disciplines, the liberal arts, and the social sciences. Accordingly, IJBC seeks manuscripts that address all areas of business communication including but not limited to business composition/technical writing, information systems, international business communication, management communication, and organizational and corporate communication. In addition, IJBC welcomes submissions concerning the role of written, verbal, nonverbal and electronic communication in the creation, maintenance, and performance of profit and not for profit business.
