背景资料：目前的研究旨在开发一种有效，可靠和不显眼的基于平板电脑的观察措施，以评估晚期痴呆症患者的参与度。参与度的视频分析量表（VASE）的目的是使每时每刻的参与度的变化在活动期间，这将是有用的未来的研究和当前的住宿护理的评级。 方法：VASE的初始版本进行了测试。表面效度和内容效度进行了评估，以验证操作定义的参与，并制定一个可接受的协议的规模。37名非专业和专业志愿者被招募来使用VASE查看和评价参与音乐活动的水平。 结果：类间系数（ICC）测试给出了一个高水平的评级协议在专业人士和非专业人士。 然而，专业人士内部的ICC结果好坏参半。线性混合模型表明，干预措施的类型（主动或被动听音乐），被评为特定的干预会议，视频的时间段和评分者的年龄可能会影响评级。 结论：结果表明，评估者以动态方式使用VASE，并且该测量能够区分干预措施。进一步的调查和调整是必要的，这被认为是一个有效的和可靠的规模在衡量参与的人与晚期痴呆症的住宿护理环境。
Background: The current study sought to develop a valid, reliable and unobtrusive tablet computer-based observational measure to assess engagement of people with advanced dementia. The Video Analysis Scale of Engagement (VASE) was designed to enable the rating of moment-by-moment changes in engagement during an activity, which would be useful for both future research and current residential care. Methods: An initial version of the VASE was tested. Face validity and content validity were assessed to validate an operational definition of engagement and develop an acceptable protocol for the scale. Thirty-seven non-professional and professional volunteers were recruited to view and rate level of engagement in music activities using the VASE. Results: An inter-class coefficient (ICC) test gave a high level of rating agreement across professionals and non-professionals. However, the ICC results of within-professionals were mixed. Linear mixed modelling suggested that the types of interventions (active or passive music listening), the particular intervention session being rated, time period of video and the age of raters could affect the ratings. Conclusions: Results suggested that raters used the VASE in a dynamic fashion and that the measure was able to distinguish between interventions. Further investigation and adjustments are warranted for this to be considered a valid and reliable scale in the measurement of engagement of people with advanced dementia in a residential care setting.
