I'm currently collecting longitudinal repetitive quantitative measures (survey tool has been developed based on initial qualitative data - exploratory sequential) from the same population (n=39) to understand patients' perception of a health problem, once they experience it during a 14-month trajectory. Also, my idea is to use the initial qualitative data (used to develop the tool), to contextualise the prospective longitudinal information about health problems obtained from this quantitative tool. Considering that the health problems, their severity and their perceptions experienced along the trajectory are very individualistic, are there any mixed-method approaches that allow interpretation of findings at an individual level? Can one simply present, interpret and discuss individual data from the whole sample?
