Persuasive message designers would like to be able to pretest messages to see which will be more effective in influencing behavioral outcomes, but pretesting using behavioral measures is commonly not practical. Examination of within-study effect size comparisons from 317 studies of 22 message variations suggests that persuasive messages’ relative effectiveness is strikingly similar across attitudinal, intention, and behavioral outcomes—with messages’ relative persuasiveness with respect to intention outcomes especially indicative of relative persuasiveness with respect to behavioral outcomes. Intention measures thus provide a convenient and accurate means of persuasive message pretesting.

使用非行为结果的有说服力的消息预测试：态度和意图影响的差异作为行为影响差异的诊断

有说服力的信息设计者希望能够对信息进行预测试，以了解哪种信息在影响行为结果方面更有效，但使用行为测量进行预测试通常是不切实际的。对 317 项针对 22 种信息变化的研究的研究内效果大小比较的检查表明，说服性信息的相对有效性在态度、意图和行为结果方面惊人地相似——信息在意图结果方面的相对说服力尤其表明与尊重行为结果。因此，意图测量为有说服力的信息预测试提供了一种方便而准确的方法。
