We developed a technology-aided intervention strategy relying on pictorial cues alone or in combination with verbal instructions and assessed these two versions of the strategy with three persons with moderate Alzheimer's disease. In Section I of the study, the strategy version with pictorial cues plus verbal instructions was compared with an existing technology-based strategy with verbal instructions. Each strategy was used with one specific activity. In Section II of the study, the strategy version with pictorial cues alone was compared with the aforementioned strategy with verbal instructions. Again, each strategy was used with one activity. Both strategy versions were effective with all three participants. The percentages of correct activity performance observed with those versions increased to above 90, and were comparable with those obtained with the existing verbal instructions strategy. A social validation assessment of the version with pictorial cues alone and the existing strategy with verbal instructions (employing university psychology students as raters) showed differences in favor of the latter strategy in terms of practicality and in favor of the former in terms of respect of participants' dignity. The implications of the findings were discussed.
我们开发了一种仅依靠图像提示或结合口头指令的技术辅助干预策略，并在三名中度阿尔茨海默病患者中评估了这两种策略版本。在研究的第一部分，我们将带有图像提示和口头指令的策略版本与现有的基于技术的带有口头指令的策略进行了比较。每个策略都用于一项特定的活动。在研究的第二部分，我们将仅带有图像提示的策略版本与上述带有口头指令的策略进行了比较。同样，每个策略都用于一项活动。这两种策略版本对所有三个参与者都有效。使用这些版本观察到的正确活动执行率增加到 90%以上，与使用现有口头指令策略获得的比率相当。对仅带有图像提示的版本和带有口头指令的现有策略（使用大学心理学学生作为评估者）进行了社会验证评估，结果表明在实用性方面，后者策略更有优势，而在尊重参与者尊严方面，前者策略更有优势。讨论了这些发现的意义。
