Reliability

Is 'reliability' the right word to use for qualitative research? Cohen et al. (2007, Ch.10) suggest a variety of different words that should be used to distinguish the variable-controlled nature of quantitative research from the variable-embracing nature of qualitative research. Points addressing reliability that are present in my research include repeating the method of data collection and analysis across several groups (related to triangulation, below) and using anonymous questionnaires to encourage honesty amongst participants (p.209).

Early on in my research plan I discussed some of the principles laid out by Newby (2010, pp.120-3) for ensuring some degree of reliability in qualitative research, particularly the concept of triangulation. In the case of my project, the point about getting information form multiple sources is the best source of reliability. The questionnaire has been answered by participants from different cohorts of the same program, so we can gain some idea of how reliable (or not) the results are by comparing different cohort responses. Although the research is qualitative in nature, the reliability can be commented on by comparing the number of responses with the actual number of participants for each cohort.
