The great diversity in the studies, their focus, design, frame
of reference, data collection and sampling mean that this is far from a unified and consistent body of literature. Nevertheless,
the studies reviewed represent the steps taken
by researchers to understand and they clearly demonstrate
an expansion in this knowledge over the period 1967—2011
across several continents. This diversity has to be borne
in mind when considering the relevance of the findings in
specific settings and in time as well as being a potential
imitation of this review. However, one could argue that the
common themes within this international body of literature
are evidence of transferability and dependability (Shenton,
2004) in the findings of the review.
