ABSTRACT
Qualitative techniques Qualitative researchers should use methods of analysis that are explicit and sy stematic (Greenhalgh and Taylor, 1997). Some experts argue that it is sufficient for only one researcher to perform data collection and analysis (Gubrium, 2007; Malterud, 2001). In these cases, the awareness and the attention of researchers in order to avoid potential bias is very important. Other experts suggest that the quality and comprehensiveness of the analysis are improved if the research involves more researchers from different scientific disciplines (Patton, 1999; Pope et al., 2000).
