In order to meet the need for accessible interventions and support for families affected by fetal alcohol spectrum disorder (FASD), we have developed an Internet-based, distance intervention for caregivers of children with FASD between the ages of four and twelve, called Strongest Families™ FASD.
To evaluate the usability of the Strongest Families FASD program content and website in terms of learnability, efficiency and acceptability.
A remote usability testing approach was conducted in two iterative cycles of participants. Synchronous online usability testing sessions were conducted, followed by asynchronous testing. A total of 18 participants were included, comprised of both health care professionals with expertise in FASD and caregivers of children with FASD. The data collected in each cycle was examined for commonalities and results were used to inform changes to the website and content after each cycle.
Participants rated the website as appealing and relatively easy and fast to use. Nevertheless, several usability problems were identified such as difficulty navigating between sections of content on the website, displaying too much content per page, and the relevance and appropriateness of the content as it related to FASD.
The identification of usability problems was an important step in refining the Strongest Families FASD program before its effectiveness is evaluated in a randomized controlled trial.
为满足为受胎儿酒精谱系障碍（FASD）影响的家庭提供便捷干预措施和支持的需求，我们为4至12岁患有FASD的儿童的照顾者开发了一种基于互联网的远程干预措施，称为“最强家庭™FASD”。
从易学性、效率和可接受性方面评估“最强家庭FASD”项目内容和网站的可用性。
对参与者进行了两个迭代周期的远程可用性测试。进行了同步在线可用性测试，随后进行了异步测试。总共包括18名参与者，其中既有在FASD方面具有专业知识的医疗保健专业人员，也有患有FASD的儿童的照顾者。检查每个周期收集的数据的共性，并将结果用于指导每个周期后网站和内容的更改。
参与者认为该网站很有吸引力，使用起来相对容易且快捷。然而，也发现了一些可用性问题，例如在网站内容的不同部分之间导航困难、每页显示的内容过多，以及内容与FASD的相关性和适用性。
在通过随机对照试验评估其有效性之前，识别可用性问题是完善“最强家庭FASD”项目的重要一步。
