eHealth interventions have been explored to provide convenient support and training to informal dementia carers. Design and usability issues may however hinder user acceptance of Web-based interventions. iSupport is an online program developed by World Health Organization (WHO) to support informal dementia carers.
This study gathers user-feedback and evaluates the usability of the European-Portuguese version of iSupport.
A mixed-methods study was conducted. Two focus groups discussions (n = 15) and 15 usability test sessions were conducted with carers and health/social support professionals to collect data on user satisfaction and requirements on the program's contents and Web interface. The usability testing protocol comprised pre/post-test surveys, a structured interview and observation of task performance in the Web platform. Content analysis of text data was performed by two independent coders.
Success rates were superior to 80% for most tasks. An average score of 89.5 on the System Usability Scale demonstrated an excellent perception of the program's usability. The program was perceived as trustworthy, and participants were globally satisfied with its aesthetics and easiness of use. Feedback and personalization were valued functional requirements, while no consensus was found for mood self-assessment or professional/peer interaction features. Lessons were considered culturally fit, thematically pertinent, and comprehensive. Suggestions for improvement were wide-ranging from program's layout to accessibility, usability, functional requirements, content format and lessons' themes.
This study derives user requirements for an evidence-based program for dementia carers. Both the study findings and usability assessment methodology can be imported to the development of similar programs worldwide.
电子健康干预措施已被用于为非正式痴呆症护理人员提供便捷的支持和培训。然而，设计和可用性问题可能会阻碍用户对基于网络的干预措施的接受。iSupport是世界卫生组织（WHO）开发的一个在线项目，旨在支持非正式痴呆症护理人员。
本研究收集用户反馈，并评估iSupport欧洲葡萄牙语版本的可用性。
开展了一项混合方法研究。与护理人员以及健康/社会支持专业人员进行了两次焦点小组讨论（n = 15）和15次可用性测试，以收集有关用户满意度以及对该项目内容和网络界面要求的数据。可用性测试协议包括测试前/后调查、结构化访谈以及对网络平台上任务执行情况的观察。文本数据由两名独立编码员进行内容分析。
大多数任务的成功率超过80%。在系统可用性量表上的平均得分为89.5，表明对该项目的可用性评价很高。该项目被认为是值得信赖的，参与者总体上对其美观性和易用性感到满意。反馈和个性化是重要的功能需求，而对于情绪自我评估或专业/同伴互动功能则未达成共识。课程被认为在文化上合适、主题相关且全面。从项目布局到可访问性、可用性、功能需求、内容格式和课程主题等方面都提出了广泛的改进建议。
本研究得出了针对痴呆症护理人员的循证项目的用户需求。研究结果和可用性评估方法均可应用于全球类似项目的开发。
