Observation versus Perception in the Conceptualization and Measurement of Participation Equality in Computer‐Mediated Communication
研究了群体决策中参与平等的两种测量方式（观察与感知）的异同，发现两者仅共享10.8%的方差，是理论上不同的构念，对研究者和实践者选择测量方法有参考价值。
ABSTRACT Participation equality, a prominent construct that has received much attention in group decision‐making research, has been studied with both perceptual and objective measures. Yet, research findings regarding participation equality have been inconsistent and equivocal. We argue that one reason for this inconsistency is how participation equality has been conceptualized and measured. In some studies, researchers have theorized and measured participation equality using observed behavior. In other studies, researchers have theorized and measured participation equality using perceptual measures. We conducted an experiment to investigate the similarities and differences between these two measures. Our results indicate that (1) perceived participation equality (PPE) and observed participation equality (OPE) are theoretically separate and distinct constructs that (2) affect and are affected by other constructs in different ways within their nomological network. OPE and PPE were more different than they were similar, sharing only 10.8% of their variance. In other words, perceptions of participation equality were predominantly influenced by factors other than observed behaviors related to participation equality. We believe that these results call for more theory and research regarding the differences between observed behavior and perceptions of behavior in group decision making. As we move into new computer‐mediated communication technologies such as Web Conferencing, Virtual Reality, and Enterprise Social Media that enable new forms of participation, we need to consider what constitutes participation and how new forms of participation should be measured and evaluated. In the large group environments of Enterprise Social Media, the differences between OPE and PPE are likely to become more pronounced.
