One of the most widely used communication tools in evaluation is the logic model. Despite its extensive use, there has been little research into the visualization aspect of the logic model. To assess the impact that design modifications would have on its effectiveness, we applied established visualization principles to revise a program model. Participants were randomly assigned to one of the six conditions to examine the effectiveness (i.e., visual efficiency, comprised of accuracy, response time, and mental effort; credibility; aesthetics) of variations to a logic model. The results demonstrated that the revisions to the model increased accuracy, perceived message credibility, and were considered more aesthetically pleasing; furthermore, revisions decreased mental effort and reduced the amount of time taken to review the model. Together, the findings from the study support the claim that visual efficiency can be improved by modifying a logic model’s formatting and design.

提高逻辑模型的有效性

评估中使用最广泛的通信工具之一是逻辑模型。尽管它被广泛使用，但对逻辑模型的可视化方面的研究却很少。为了评估设计修改对其有效性的影响，我们应用既定的可视化原则来修改程序模型。参与者被随机分配到六个条件之一，以检查逻辑模型变化的有效性（即视觉效率，包括准确性、响应时间和脑力劳动；可信度；美学）。结果表明，对模型的修改提高了准确性、感知信息的可信度，并且被认为更美观；此外，修订减少了脑力劳动并减少了审查模型所需的时间。一起，
