摘要
Objective:This study provides a preliminary evaluation of the usability and acceptability of a mobile application(sexual assault care algorithm,SACA).Methods:An explanatory sequential mixed methods research was used.A quantitative survey was followed up by a qualitative study.A convenience sample of participants(n=4)was recruited.The research was conducted on a one-on-one basis.In the quantitative phase,a random assignment technique was used to divide four participants into two groups of two participants each.Post-Study System Usability Questionnaire(PSSUQ)and Acceptability e-Scale were used to collect quantitative data.In the qualitative phase,interview,observation,and documentation were used to collect qualitative data.Data were analyzed both quantitative and qualitatively.The qualitative data were linked with the initial quantitative data to determine how the follow-up qualitative data helped explain the initial quantitative results.Results:The quantitative results suggested that SACA has high usability(5.05±1.83)and acceptability(3.81±1.22).The qualitative results further indicate that the participants thought SACA was easy to use and useful,and most of them would recommend it to others.Areas of improvement include adding features that would calculate and validate the elapsed time since the sexual assault,adding explanations to some buttons,and providing training.Conclusions:Our findings highlight the value of using a mixed methods research design to conduct a usability and acceptability test.Nurses are more likely to adopt a new technology for their evidencebased practice when the technology is easy to use and useful and requires less time to find the right piece of guideline evidence.Individualized training needs to be designed based on users'characteristics.
目的初步评估一款性侵害受害儿童治疗指南(sexual assault care algorithm,SACA)手机应用软件的易用性和接受度。方法采用混合研究方法。采用便利抽样法招募4名护士。采用后测系统可用性问卷(Post-Study System Usability Questionnaire,PSSUQ)和接受度量表(Acceptability e-Scale)收集量性数据。采用访谈法、观察法和文件分析法收集质性资料。将量性与质性资料相结合进行分析,并以第二阶段收集的质性资料解释第一阶段的量性调查结果。结果研究结果显示,SACA具有良好的易用性(5.05±1.83)和接受度(3.81±1.22)。研究参与者认为SACA不仅易于使用,而且有效,多数愿意将SACA推荐给他人。需要改进的地方包括:添加计算和验证时间的功能(被性侵犯后已有多长时间),给某些按键添加解释,以及给使用者提供培训。结论本研究强调了混合研究方法在易用性和接受度测试中的价值。若一项新技术有用且易用,能让使用者在较短时间内找到临床指南中相应的内容,护士将更倾向于接受这项新技术来帮其进行循证实践。需要根据使用者特点定制个性化的培训。
