Table 1 Four Dimension Criteria to Assess the Rigor of this Qualitative Study
Rigor Criteria | Strategies applied in our study |
|---|---|
Credibility | • 17 interviews, 60 min each, January to May 2015 (five months) • Interview protocol, tested in two pilot interviews • Skillful researchers for interview and data analysis • Two moderators for each interview, one as interviewer and one as note-taker • Immediate debriefing after interviews • Double checking transcribed interviews notes taken by both researchers |
Dependability | • Prepared study protocol and briefing before interviews • Track record of interviews and detailed information related • Coding accuracy and inter coders’ reliability testing (Kappa agreement testing) • Using software (NVIVO10) for analysis |
Confirmability | • Immediate descriptive review of transcripts to identify diversities and similarities of data |
Transferability | • Sampling based on Urban HEART results for classifying districts and selecting interviewees from all socio-economic classes • Examining repeated coding after each interview and not arisen new nodes and additional subthemes in the final analysis |
