The use of mixed methodology in evaluating complex interventions: identifying patient factors that moderate the effects of a decision aid

摘要

Background. Mixed method research, the combined use of qualitative and quantitative methods, is increasingly popular in health services research, especially as a way to examine ‘complex interventions’. This paper seeks to provide a case example of the use of mixed methods in the analysis of a complex intervention (a computerized interactive decision aid) to test whether their use affords insights into potential moderators of the intervention (i.e. patient factors that were associated with the impact of the intervention).
