This scoping review comprehensively describes evidence of using peer support to assist informal carers of individuals with dementia (any type). A systematic search of 11 databases (CINAHL, Cochrane Library, Medline, Embase, PsychInfo, Web of Science, Scopus, Science Direct, ProQuest, TRIP and PubMed) was conducted for research published between 2007-2017 focussing on informal dementia carers, and research designs with interventions incorporating or consisting exclusively of peer support. Authors worked independently to screen retrieved articles, review applicability and extract data.
