Dementia can interfere with the maintenance of social interactions. The ability to participate in social interactions is one of the elements that enables good social health (Hubert et al., 2011), and having dementia does not automatically eliminates the person's opportunity to have good social health (Vernooij-Dassen and Jeon, 2016). We highlighted in a previous study that people with dementia who did not know each other interacted spontaneously when they were in a stimulating social interaction setting (Mabire et al., 2016). However, a lack of activity and social interaction in nursing homes is still a widespread issue (Harper Ice, 2002). Stimulation of social interactions is rarely used as an intervention and social interactions are seldomly used as social health related outcomes.
