奖励发帖：有关形成型和反映型的区别

[em17]

超感激大大分享!!!

楼上的怎么没有被奖励啊？现在才有77个论坛币？版主怎么回事呢？

大家相互学习，资料真是不错

不错的资料，谢谢分享

发表在MISQ上的这篇文章是IS领域关于形成性指标的一些要求，提出了形成性指标在IS领域应用的问题，对比了形成性和反应性指标的区别，很有借鉴意义。

Title: Specifying formative constructs in information systems research
Author: Petter, S.; Straub, D.; Rai, A.
Source: Mis Quarterly, 2007, 31(4): 623-656
Abstract
      While researchers go to great lengths to justify and prove theoretical links between constructs, the relationship between measurement items and constructs is often ignored. By default, the relationship between construct and item is assumed to be reflective, meaning that the measurement items are a reflection of the construct. Many times, though, the nature of the construct is not reflective, but rather formative. Formative constructs occur when the items describe and define the construct rather than vice versa.
      In this research, we examine whether formative constructs are indeed being mistaken for reflective constructs by information systems researchers. By examining complete volumes of MIS Quarterly and Information Systems Research over the last 3 years, we discovered that a significant number of articles have indeed misspecified formative constructs. For scientific results to be valid, we argue that researchers must properly specify formative constructs. This paper discusses the implications of different patterns of common misspecifications of formative constructs on both Type I and Type II errors. To avoid these errors, the paper provides a roadmap to researchers to properly specify formative constructs. We also discuss how to address formative constructs within a research model after they are specified.

我主要参考的是以下两篇，特别是发表在MIS Quarterly上的这篇，可以帮助简单判断是反应型还是构成型测量的文章，这篇文章对于测量变量是反映还是构成关系讲的很透彻。另外，构成型变量的问题在管理学的IS领域应该遇到的很多。
