Health services research has been dominated by the biomedical paradigm and
positivism, and the funding cultures of biomedicine have dictated the choic
e of method used by researchers. Social science paradigms, however, have be
en recognised as increasingly important within health services research and
both quantitative and qualitative methods are accepted as appropriate. Old
er people with dementia have usually been excluded from or marginalised in
studies about dementia because of traditional assumptions about the ability
or appropriateness of people with dementia to act as participants or respo
ndents. The choice of research method should be driven by theory and not by
ideological or political prescription. Theory-driven pluralistic approache
s to method will facilitate participation of people with dementia in resear
ch through the valuing of personhood. There are no unique methodological ch
allenges in researching dementia. Rather, the complex nature of dementia an
d dementia care highlight the methodological challenges of investigating co
mplex social phenomena.
