Digital, multimedia information resources (MMIs) containing text, video, animation and pictures are a promising alternative to written participant information materials designed to inform children, adolescents and parents about healthcare trials, but little research has tested whether they are fit for purpose. This study employed a consecutive groups design and user testing questionnaire to assess whether participants were able to find and understand key information in multimedia resources. Two rounds of testing were completed. In each round, seven children aged 7-11 tested the MMI with a parent; six adolescents aged 12-17 and seven parents tested the MMI independently. After round 1, the resources were revised based on participant scores, behaviour and feedback. Round 1 identified problems with 2/10 information items (length of trial and use of insulin pump); only 3/20 participants could locate all information items without difficulty. After revisions, 14/20 participants scored a clear round. Information comprehension was high: 96% understood in round 1 and 99% in round 2. Participant feedback on the multimedia resources was positive, although presentation preferences varied. User testing was employed successfully with children, adolescents and parents to identify issues with, and improve, multimedia resources developed to inform potential healthcare trial participants.
包含文本、视频、动画和图片的数字多媒体信息资源（MMIs）是一种很有前景的替代方案，可替代旨在向儿童、青少年和家长介绍医疗保健试验的书面参与者信息材料，但很少有研究测试它们是否符合目的。本研究采用连续组设计和用户测试问卷来评估参与者是否能够在多媒体资源中找到并理解关键信息。完成了两轮测试。在每一轮中，7名7至11岁的儿童与一名家长一起测试MMI；6名12至17岁的青少年和7名家长独立测试MMI。在第一轮测试后，根据参与者的得分、行为和反馈对资源进行了修订。第一轮测试发现10项信息中有2项存在问题（试验时长和胰岛素泵的使用）；只有3/20的参与者能够毫无困难地找到所有信息项。修订后，20名参与者中有14名获得了明确的通过。信息理解程度很高：第一轮测试中有96%的人理解，第二轮测试中有99%的人理解。尽管呈现偏好各不相同，但参与者对多媒体资源的反馈是积极的。成功地对儿童、青少年和家长进行了用户测试，以识别为告知潜在医疗保健试验参与者而开发的多媒体资源存在的问题并加以改进。
