Understanding factors associated with young people’s mental wellbeing and evaluating the effectiveness of interventions that are thought to promote mental wellbeing is becoming increasingly important, given the rise in prevalence of diagnosable mental health conditions within this population. Part one of this portfolio presents an empirical paper that investigated the relationship between self-compassion and psychological resilience in a UK adolescent sample. The role of self-reported stress as a mediator and gender as a moderator in this relationship was also explored. There was a significant relationship between self-compassion and psychological resilience, and this relationship was partially mediated by self-reported stress. The relationship between self-compassion and resilience was not moderated by gender.
