Research suggests that testimonials, or first-person narratives, influence health behavior and health-related decision making, but few studies have examined conceptual factors that may be responsible for these effects. In the current study, older adults who were due for colorectal cancer screening read a message about screening that included a testimonial from a similar other who had previously made the screening decision. We assessed participants' identification with the testimonial character and the degree to which they found the message to be vivid. We explored associations between these factors and participants' knowledge following the message, mood, certainty about screening, and their behavioral intentions to look for more information about screening and to have a test in the next year. In bivariate analyses, identification and vividness were both significantly, positively associated with knowledge and behavioral intentions to have screening in the next year. However, multivariate analyses revealed that only vividness remained significantly associated with knowledge and intentions to be screened.
研究表明，推荐（证言，或第一人称叙述）会影响健康行为和与健康相关的决策，但很少有研究探讨可能导致这些影响的概念因素。在当前的研究中，即将进行结直肠癌筛查的老年人阅读了一条关于筛查的信息，其中包括一位之前做出过筛查决定的相似他人的证言。我们评估了参与者对证言人物的认同程度，以及他们对信息的生动程度的看法。我们探讨了这些因素与参与者在收到信息后的知识、情绪、对筛查的确定性以及他们寻找更多关于筛查信息并在明年进行检查的行为意向之间的关联。在单变量分析中，认同度和生动度都与知识和明年进行筛查的行为意向呈显著正相关。然而，多变量分析显示，只有生动度与知识和接受筛查的意向仍然显著相关。
