The opening of a new Special Care Unit provided the opportunity to study the effect of reduced social density (fewer residents) and spatial density (more area per person) on the behaviour of residents with dementia. Two groups (N = 64) were observed at three periods spaced six months apart. As hypothesized, there was a greater improvement in Disruptive and Nondisruptive behaviour in the experimental group (move from high to low density) compared to the comparison group (constant high density). Findings suggest that unit density is an important determinant of behaviour in elderly residents with dementia.


L'ouverture d'une nouvelle unité de soins spéciaux a permis d'étudier l'effet de la densité sociale réduite (moins de résidents) et de la densité spatiale (plus d'espace par personne) sur le comportement de résidents avec démence. Deux groupes (N = 64) ont été observés pendant trois périodes espacées de six mois chacune. Tel que théorisé, il y a eu plus d'amélioration dans le comportement perturbateur et non perturbateur du groupe expérimental (passant de haute à basse densité) par rapport au groupe de comparaison (haute densité constante). Les résultats indiquent que la densité de l'unité résidentielle est un déterminant important pour le comportement des résidents âgés avec démence.
