Developing, conducting, and sharing the results of a good intervention study is a challenging task, requiring considerable effort and expertise. I offer my reflections on this enterprise, commenting on the need for studying complex interventions, using multiple methodologies. I also argue that such research should be theoretically grounded and, more frequently than is currently the case, should test theoretical propositions. Finally, I comment on conducting research with limited funding, the importance of veracity when sharing research findings, and the need for more intense and extended preparation for new intervention researchers.
