"Boy, what are we all doing? We are crazy, really crazy": a qualitative study of psychosocial processes around an atypical one-time smoking cessation course.

Background: Smoking prevalence is still high, which requires effective interventions that help many people who smoke at once in addition to time-consuming individual interventions. 'I Quit' is a large-scale smoking cessation course in The Netherlands. This qualitative study explored I Quit participants' experiences during and after the course, and perceptions of whether and how the course may have altered their smoking behavior.

Background: Few European smokers receive professional counselling when attempting to quit smoking, resulting in suboptimal success rates and poor health outcomes. Healthcare providers in general practice play an important role in referring smokers to smoking cessation counselling. We chose the Netherlands as a case study to qualitatively explore which factors play a role among healthcare providers in general practice with regard to referral for smoking cessation counselling organised both inside and outside general practice.

National and international media were interested in this story and we soon began receiving questions about this topic in general practice. In this article, we shed light on the process that resulted in the misinterpretation of observational research by scientists and the media.
