The research is extremely timely due to the new data on wellbeing at age 23. This is a crucial life stage in which pressure to establish a family and career take place. Understanding ways in which individuals could flourish during this period could have a significant impact on their future mental health and wellbeing. Wellbeing also has significant implications for policy makers with nationwide surveys and the ‘What Works Centre for Wellbeing’ now in place to better inform decision-making and support communities, government and businesses in improving wellbeing. Thus, the present study aims to provide further support for the importance of wellbeing research and hopes to identify factors associated with wellbeing that need accounting for. If peer victimisation in adolescence is demonstrated to significantly implicate later wellbeing, experiences of peer victimisation should be considered when assessing an individual’s mental health and wellbeing. Additionally, targeting victimisation in schools could be an effective intervention to prevent poor outcomes and improve later wellbeing.
