The non-image-forming effects of luminous radiation on people with intellectual disabilities or dementia received attention from researchers. Such studies, however, have generally been conducted using disparate methodologies which precludes generalization and reproducibility.
The aim of this study was to determine the practical applicability of measurement devices for studies investigating non-image-forming effects of luminous radiation, specifically for people with intellectual disabilities or dementia.
In three experiments, ten cognitive impaired people and thirty-nine unaffected subjects participated by wearing one or more portable devices. Six devices were assessed in total. Measurement data was accompanied with user experiences obtained from questionnaires, interviews and observations in order to assess the devices on practical and comfort issues.
On average, the devices worn by the cognitive impaired subjects were not experienced as annoying or irritating. No significant differences are found between genders and for one of the portable devices significantly less annoyance was reported by the cognitive impaired participants compared to the unaffected group of participants.
The three phases of the research process in towards measuring personal luminous exposures are: selection of the most suitable portable device, application of the assessment method, and the application of the device in the (pilot) study.
However, the findings of this study suggest that inaccuracies potentially caused by practical and comfort issues associated with the portable devices need to be considered.
光辐射对智障或痴呆患者的非成像效应受到了研究人员的关注。然而，此类研究通常采用不同的方法进行，这使得研究结果难以推广和重复。
本研究的目的是确定用于研究光辐射非成像效应的测量设备的实际适用性，特别是针对智障或痴呆患者。
在三个实验中，10名认知障碍者和39名未受影响的受试者佩戴一个或多个便携式设备参与实验。总共评估了6种设备。测量数据还伴有通过问卷调查、访谈和观察获得的用户体验，以便从实际和舒适度方面评估这些设备。
平均而言，认知障碍受试者佩戴的设备并未给人带来烦扰或刺激的感觉。在性别之间未发现显著差异，并且在一种便携式设备上，与未受影响的参与者组相比，认知障碍参与者报告的烦扰明显更少。
测量个人光暴露的研究过程的三个阶段是：选择最合适的便携式设备、应用评估方法以及在（试点）研究中应用该设备。
然而，本研究结果表明，需要考虑与便携式设备相关的实际和舒适度问题可能导致的测量不准确。
