Qualitative Methods

9. Summary

Quantitative researchers are rightly concerned to establish correlations between variables. However, while their approach can tell us a lot about inputs and outputs to some phenomenon (e.g. communication), it has to be satisfied with a purely ‘operational’ definition of the phenomenon and does not have the resources to describe how that phenomenon is locally constituted (see Figure 1). As a result, its contribution to social problems is necessarily lopsided and limited.

Accounts on the OBSSR e-Learning site enable you to save notes as you read the contents of the site.  Notes are a way for you to save a spot on the site with your own comments and title applied to it.  Think of it as putting a sticky note paper in a book to remember a place and leave a thought or two of your own for later reference.

The main strength of qualitative research is its ability to study phenomena which are simply unavailable when quantitative researchers seek to establish correlations between variables. The latter approach can tell us a lot about inputs and outputs to some phenomenon (e.g. the link between the social characteristics of doctors and patients and compliance), but it has to depend upon the use of prior ‘measures’ and does not have the resources to describe how that phenomenon (physician-patient communication) is locally constituted. Think, for instance, of what Heath’s (2004) visual data can tell us about what actually happens in the consulting room.

The conclusion I draw from this argument is that we can most satisfactorily answer research questions by combining separate quantitative and qualitative studies.

For instance, my research on HIV-test counseling (Silverman,1997) used similar data to Heath’s. Although it could add to our understanding of processes within counselor-client communication, it could not document the impact of this communication upon subsequent client behaviour. This carries an important message.

While quantitative research is blind when it does not have access to qualitative research on the local construction of social phenomena, qualitative research is immeasurably strengthened when it is combined with quantitative data about the inputs and outputs of its chosen topics. Such a division of labour would seem to be the most fruitful future path.
