As a prevention and promotion oriented science, positive psychology has much to add to early intervention approaches with children and adolescents. Indeed, scholars in positive psychology have written about the need to work positively with youth so as to prevent down-stream effects on mental illness in adulthood. As Douglas Frederick, famously asserted, ‘it is easier to build strong children than repair broken adults.’ Based upon a review paper currently in development (Owens & Waters, in progress), this roundtable will discuss positive psychological interventions (PPIs) available to children and adolescents in two different contexts: schools and clinical settings. We are hoping to have a fruitful discussion with those who have used, developed, or are studying PPIs with children and adolescents to further the science and practice related to this topic.
