Firstly, let's examine what qualitative research means. Very broadly, research can be split into two major types: quantitative and qualitative. The former measures variables that are directly quantifiable or capable of being expressed in quantities as numbers, whereas the latter measures variables that are either indirectly measurable with numbers or completely incapable of quantifying. In this case, quality of life is a variable which does not inherently lend itself to quantification, but a scale and measurement system used by the group quantifies it indirectly.
The qualitative approach would consist of measuring qualitative variables - which we just described the major variable being studied as being the health-related quality of life. We also see that the researchers have indirectly quantified quality of life using a specifically designed questionnaire (look under Methods). Qualitative research also aims to correlate changes in qualitative variables with another variable, be that qualitative or quantitative. We can see that the objective of this study is to see if such correlation exists between health-related quality of life (HRQL) and that of experienced pain as reported via a measurement tool in chronic pain patients. We also see statistical approaches to determining the likelihood ...
