Background and aim: Patient and public involvement (PPI) has potential to enhance health‐care research and is increasingly an expectation, particularly for many funding bodies. However, PPI can be tokenistic, which may limit this potential. Furthermore, few studies report PPI processes and impact, particularly in doctoral research studies, which are seldom reported in peer‐reviewed papers. The aim of this paper was to explore the impact of PPI on two health‐related doctoral research studies and identify how PPI could be used meaningfully at this level.
