There are two maj<strong>or</strong> validity threats with qualitative research: researcher bias and interviewee<br />
reactivity; that is ‘what the inf<strong>or</strong>mant says is always influenced by the interviewer and the<br />
interview situation’ (Maxwell, 2005, p.109). Addressing reliability and validity issues in<br />
qualitative research is complex in that the purpose and type <strong>of</strong> data do not lend themselves to<br />
the tests n<strong>or</strong>mally associated with reliability and validity issues in quantitative studies (see<br />
Wallend<strong>or</strong>f & Belk, 1989; Winter, 2000). This research takes into account Guba and<br />
Lincoln’s (1988) four criteria f<strong>or</strong> judging –soundness <strong>of</strong> qualitative research and explicitly<br />
<strong>of</strong>fered these as an alternative to m<strong>or</strong>e traditional quantitatively-<strong>or</strong>iented criteria: credibility,<br />
transferability, dependability and confirmability.<br />
F<strong>or</strong> this study, these have been addressed by clear statements <strong>of</strong> task, participant type and<br />
participant selection; detailed rep<strong>or</strong>ting <strong>of</strong> procedures; transcriptions were done by<br />
independent transcribers. The study includes multiple coders and participant verification to<br />
minimise interpretation bias ‘respondent validation’ <strong>or</strong> ‘member checking’ was carried out<br />
(Maxwell, 2005:110; Creswell and Clarke, 2007). This was managed by having participants<br />
check and approve whether the findings accurately reflect their experience.<br />
