信息为实证传播研究带来了根本性的挑战和机遇。为了应对这些挑战和机遇，我们区分消息的可变性（在给定的研究中的消息的定义和操作功能）和消息的异质性（所有的消息功能，是未定义的，在给定的研究中未测量），并建议的方法来定义和操作消息的可变性。我们还确定了替代的消息采样，选择，研究设计和分析策略响应的问题，在实验和调查研究的消息的变异性和异质性。最后，我们的建议，旨在推进研究的信息在通信研究。
Messages pose fundamental challenges and opportunities for empirical communication research. To address these challenges and opportunities, we distinguish between message variability (the defined and operationalized features of messages in a given study) and message heterogeneity (all message features that are undefined and unmeasured in a given study), and suggest approaches to defining and operationalizing message variability. We also identify alternative message sampling, selection, and research design and analysis strategies responsive to issues of message variability and heterogeneity in experimental and survey research. We conclude with recommendations intended to advance the study of messages in communication research.
