We investigated the relationship of processing fluency of written information about exercise to participants’ perceived interest, safety, self-efficacy, outcome expectation, and behavioral intention regarding the exercise. We randomly assigned 400 men and women aged 40–69 years to control or intervention conditions. Perceived self-efficacy of performing the exercise in the intervention group (i.e. easy to read) was significantly higher than that in the control group (i.e. difficult to read) (p = 0.04). Easy-to-read written health information may be important not only for making written health information comprehensible but also for increasing readers’ self-efficacy for adopting health-related behaviors.

书面健康信息的高可读性和低可读性对自我效能的影响：加工流利性效果的随机对照研究

我们调查了有关锻炼的书面信息的处理流畅程度与参与者对锻炼的感知兴趣，安全性，自我效能，结果期望以及行为意图之间的关系。我们随机分配了400名40-69岁的男性和女性以控制或干预疾病。干预组（即易于阅读）的锻炼自我感知自我效能显着高于对照组（即难以阅读）（p = 0.04）。易于阅读的书面健康信息可能不仅对理解书面健康信息很重要，而且对于提高读者采用与健康相关的行为的自我效能也很重要。
