There is a growing body of literature on children’s wellbeing. However, historically, focus has been on adults’ perspectives, leading to adult-centric views of wellbeing. Although recent years have witnessed an increase in researchers eliciting children’s perspectives, it is not clear whether children's perceptions of wellbeing are universal, or whether they are culturally distinct. This study sought to explore children’s perceptions of wellbeing across Wales and the Czech Republic. Semi-structured interviews were conducted with 53 children aged 9–12 years and analysed via thematic analysis. The results revealed similarities in the perceptions of children in Wales and Czech Republic, with children in both cultures drawing on risk and protective factors that children believe impacts on their wellbeing. Risk factors include disrupted family relationships, peer diﬃculties, and anxiety, while protective factors include positive parent-child relationships, meaningful friendships, and eﬀective coping strategies. This paper suggests that warm parent-child and child-peer interactions contribute to children’s positive socioemotional functioning.
