An enriched environment for residents with dementia may have a positive effect on the rest-activity rhythm. A small scaled homelike special care unit might be such an enriched environment. The present study shows whether the rest-activity rhythm of residents with moderate to severe dementia responds positively to a transfer from a regular Special Care Unit (SCU) to a small scaled homelike SCU.
Initially, a group of 145 residents living in a regular SCU participated. Out of this group, 77 residents moved to a small scaled homelike SCU. This group was compared to the group of 68 residents that remained at the regular SCU. Rest-activity rhythm was assessed by means of actigraphy and observation scales before and after relocation.
No significant main effects nor significant interaction effects in intradaily and interdaily activity were found for the data of 38 residents in the small scaled homelike SCU and 20 residents of the regular SCU. The effect sizes, however, ranged from small to large.
Considering the effect sizes, a new study with a larger number of participants is necessary before firm conclusions can be drawn.

为痴呆症患者营造丰富环境可能对其休息 - 活动节律产生积极影响。小型家庭式特殊护理单元可能就是这样一个丰富的环境。本研究旨在表明中重度痴呆症患者的休息 - 活动节律对从常规特殊护理单元（SCU）转移至小型家庭式SCU是否会产生积极反应。
最初，一组145名居住在常规SCU的居民参与研究。在这组居民中，77名居民转移至小型家庭式SCU。将这组居民与留在常规SCU的68名居民组成的组进行比较。在搬迁前后，通过活动记录仪和观察量表对休息 - 活动节律进行评估。
对于小型家庭式SCU中的38名居民和常规SCU中的20名居民的数据，在日内和日间活动中未发现显著的主效应或显著的交互效应。然而，效应大小范围从小到 大。
考虑到效应大小，在得出确切结论之前，有必要进行一项参与者数量更多的新研究。
