“…Dementia Care Mapping (DCM) is a widely used method to support staff working in dementia care in psychogeriatric nursing homes (Barbosa, Lord, Blighe, & Mountain, 2017;Chenoweth et al, 2009;Jeon et al, 2012;Kuiper, Dijkstra, Tuinstra, & Groothoff, 2009;Rokstad et al, 2013;Van de Ven, 2014). It is promising for staff working with older people with intellectual disability and has a number of characteristics that are innovative for this field: it is a relatively structured psychosocial method, it is based on principles of person-centred care, and it is specifically aiming at people with dementia (Finnamore & Lord, 2007;Jaycock, Persaud, & Johnson, 2006;Persaud & Jaycock, 2001;Schaap, Dijkstra, Finnema, & Reijneveld, 2017).…”
