The goal of the in-depth interviews was to elicit the
participants' interpretations of their experience by capturing
how the world is perceived, understood and experienced
by those whose lives are a part of it The use of
interviewing with observation enhanced validity as it
assured that the truth m observations was checked with
the active questioning of the interview situation and vice
versa (Chemtz & Swanson 1986, Schatzman & Stiauss
1973) Participant observation also provided opportunities
for prolonged contact with participants to validate aspects
of the data and ensure the rigour of the study
