how to conduct qualitative research
interviews or focus groups, its recommended to use purposive sampling
uses of qualitative data pre RCT
generate hypotheses, develop interventions, see issues to healthcare
use of qual during RCT
intervention fidelity, implementation and change processes
uses of qual after RCT
reasons for findings and explain variations, further hypotheses
QUART qual research in trials study
makes more human sensitive
interpretations for variability and unexpected findings
feasibility and relevance to cultural and other needs
efficiency and barriers
qual research value
explore context
understand barriers and findings
why it works or doesnt
Pre qual
develop recruitment materials
identify logistical issues
training
post qual
supplements and fleshes out quantitative findings
shows experiences and acceptability
