The BNIM (biographic-narrative-interpretive-method) approach has been used in a number of contexts. A major use was BNIM interviews with staff and clients around a Healthy Living community centre in East London (UK), Bromley by Bow. This was a multi-authored three year study using a variety of other methods as well as biographic-narrative interviews. See Froggett, Chamberlayne, Buckner and Wengraf (2005).
There are other references in the free BNIM Short Guide and Detailed Manual’s Bibliography A. If interested, you or anybody else could write to me off-list (tomATtomwengraf.com) and I could send you an electronic copy.
You don’t say what your interest is, Valentina, it would be nice to know more…
Best wishes
