The aim of this study was to examine pharmacy students' experiences of a small ACT-based intervention that was implemented as a 7-week course with weekly online modules. Students' well-being, experiences of stress, organised studying and psychological flexibility were measured with questionnaires at the beginning and end of the course. Students' experiences of how the course affected their studying were analysed from open-ended responses and a reflective journal. The results show that students' well-being and time and effort management increased during the course. Students experienced that the course affected their studying in various ways. This study showed that it is possible to foster students' well-being and study skills with an online intervention course. More research is needed to identify the long-lasting effects of these kind of interventions.
