目的：专家建议成年人进行心血管风险评估。我们研究了与数字信息相比，图标阵列是否能提高理解、回忆、CVR感知和行为意图。方法：有中高心血管风险的男性门诊退伍军人参加了一项随机对照试验，该试验采用计算机教程呈现个性化风险。消息格式以3种格式呈现：百分比、频率和带有图标数组的频率。我们在干预后立即（T1）评估理解能力，在干预后20分钟（T2）和2周（T3）评估回忆能力。我们评估了T1的重要性/严肃性、坚持的意图和自我效能感。自我报告的依从性在T3时进行评估。结果：共有120名男性退伍军人参加。年龄、教育、种族、健康素养和计算能力在基线时具有可比性。T1时的理解水平[p = .31]和T3时的回忆水平[p = .10]没有差异。使用图标数组的准确率低于百分比或频率在T2 [p]
Objective: Experts recommend that adults have their global cardiovascular risk assessed. We investigated whether icon arrays increase understanding, recall, perception of CVR, and behavioral intent as compared with numerical information.Methods: Male outpatient veterans, at an intermediate to high cardiovascular risk participated in a randomized controlled trial of a computer tutorial presenting individualized risk. Message format was presented in 3 formats: percentages, frequencies, and frequencies with icon arrays. We assessed understanding immediately (T1) and recall at 20 min (T2) and 2 weeks (T3) after the intervention. We assessed perceptions of importance/seriousness, intent to adhere, and self-efficacy at T1. Self-reported adherence was assessed at T3.Results: One-hundred and twenty male veterans participated. Age, education, race, health literacy and numeracy were comparable at baseline. There were no differences in understanding at T1 [p = .31] and recall at T3 [p = .10]. Accuracy was inferior with frequencies with icon arrays than percentages or frequencies at T2 [p
