The last two decades have seen a notable growth in the use of qualitative methods
for applied social policy research. Qualitative research is now used to explore
and understand a diversity of social and public policy issues, either as an
independent research strategy or in combination with some form of statistical
inquiry. The wider use of qualitative methods has come about for a number of
reasons but is underpinned by the persistent requirement in social policy fields
to understand complex behaviours, needs, systems and cultures.
