Supplementary Material for: Development of an Audiovisual Tool on Peripheral Arterial Disease and Preliminary Suitability Assessment

<b><i>Background:</i></b> Increasing health literacy in people with chronic illness is essential to prevent disease complications and to promote responsible and conscious decision-making. Therefore, an audiovisual tool was developed to promote literacy about peripheral arterial disease (PAD) in a hospital setting, and a preliminary evaluation of the tool’s suitability was carried out. <b><i>Material and Methods:</i></b> The tool was developed by a multidisciplinary team. The preliminary assessment of the suitability study of an audiovisual tool was carried out with a sample of 7 patients with PAD admitted to an Angiology and Vascular Surgery Service and with a group of four professionals specialized in the subject (health literacy and PAD). The design, elaboration, and production of the audiovisual tool were based on a literature review, an informal focus group with patients, a communication model, and an empirical model of behavioral change. Through this preliminary suitability assessment study, we identified the suitability characteristics of this audiovisual tool that can be transmitted in waiting rooms and vascular surgery hospitalizations. The Suitable Assessment of Material (SAM) was used by professionals and patients to obtain different appropriateness factors for each of the 11 videos. <b><i>Results:</i></b> The audiovisual tool developed and built for patients with PAD proved to be accessible, understandable, and attractive for people with low levels of education. The patients were satisfied with the audiovisual tool and highlighted positive points, also reporting some suggestions for changes. Health professionals evaluated the 11 videos with a high level of adequacy ranging from 82% to 93.05% adequacy. Out of 19 factors (from the SAM), the quality of the illustrations, the presence of tables and lists, and stimulation and incentive to learning were the two dimensions scored as least appropriate/used. <b><i>Conclusion:</i></b> The audiovisual tool developed to improve health literacy on PAD presented preliminary suitability characteristics that make it a high-quality material to be used in future studies that evaluate the effectiveness of the tool with this population.**背景：** 提升慢性病患者的健康素养（health literacy），对于预防疾病并发症、促进负责任且理性的临床决策至关重要。为此，研究团队开发了一款适用于医院场景的外周动脉疾病（peripheral arterial disease, PAD）健康素养提升视听工具，并对该工具的适宜性开展了初步评估。 **材料与方法：** 本视听工具由多学科团队开发。本次工具适宜性初步评估研究的样本包括7名收治于血管病与血管外科科室的PAD患者，以及4名健康素养与PAD领域的专业医护人员。视听工具的设计、制作与产出基于文献综述、患者非正式焦点小组访谈、传播模型以及行为改变实证模型。通过本次初步适宜性评估研究，我们明确了可在医院候诊室与血管外科住院病区推广的该视听工具的适宜性特征。研究采用材料适宜性评估量表（Suitable Assessment of Material, SAM），由医护人员与患者分别对11段视频的各项适宜性指标进行评分。 **结果：** 本次开发的针对PAD患者的视听工具，在低教育水平人群中展现出良好的可及性、易懂性与吸引力。参与评估的患者对该视听工具表示满意，不仅肯定了其优势，还提出了部分修改建议。医护人员对11段视频的适宜度评分介于82%至93.05%之间，整体适宜度较高。在材料适宜性评估量表的19项评估维度中，插图质量、图表与列表的呈现，以及学习激励与引导这两项维度被评为最不适宜/最少使用的维度。 **结论：** 本次开发的用于提升PAD患者健康素养的视听工具，已展现出初步适宜性特征，可作为高质量素材用于后续针对该人群开展的工具有效性评估研究。
