Background/Aims: Little is known about anxiety and its associations among persons with dementia in nursing homes. This study aims to examine anxiety, anxiety symptoms, and their correlates in persons with dementia in Norwegian nursing homes. Methods: In all, 298 participants with dementia ≥65 years old from 17 nursing homes were assessed with a validated Norwegian version of the Rating Anxiety in Dementia scale (RAID-N). Associations between anxiety (RAID-N score) and demographic and clinical characteristics were analyzed with linear regression models. Results: Anxiety, according to a cutoff of ≥12 on the RAID-N, was found in 34.2% (n = 102) of the participants. Irritability (59.7%) and restlessness (53.0%) were the most frequent anxiety symptoms. The participants' general physical health, a wide range of neuropsychiatric symptoms, and anxiolytic use were significant correlates of higher RAID-N scores. Conclusion: Knowledge about anxiety, anxiety symptoms, and their correlates may enhance early detection of anxiety and planning of necessary treatment and proactive measures among this population residing in nursing homes.
