Audiovisual and narrative information are often used in online decision aids. However, few studies have tested whether these strategies are more effective compared to other types of information. We tested the effect of these strategies on satisfaction with the information, recall and informed decision-making in a 2 (Modality: audiovisual vs. textual) x 2 (Narration style: narrative vs. factual) experimental design. Data was collected in an online experiment among 262 analogue cancer patients. Since most cancer patients are older people, we also assessed if the effectiveness of these strategies differs depending on the patient’s age. Data was analyzed using Structural Equation Modeling. Findings showed audiovisual modality had a positive effect on satisfaction. Moreover, audiovisual modality improved recall, both directly and indirectly via satisfaction, which subsequently resulted in better-informed decision-making. Narratives resulted in more satisfaction, but not better recall or informed decision-making. These effects were found in patients of all ages.

视听和叙述信息通常用于在线决策辅助工具。然而，很少有研究测试这些策略与其他类型的信息相比是否更有效。我们在 2（模式：视听与文本）x 2（叙述风格：叙述与事实）实验设计中测试了这些策略对信息满意度、回忆和知情决策的影响。数据是在 262 名类似癌症患者的在线实验中收集的。由于大多数癌症患者都是老年人，我们还评估了这些策略的有效性是否因患者的年龄而异。使用结构方程模型分析数据。结果表明，视听方式对满意度有积极影响。此外，视听模式提高了回忆，直接和间接通过满意度，随后导致更明智的决策。叙述会带来更多的满足感，但不会带来更好的回忆或明智的决策。在所有年龄段的患者中都发现了这些影响。
