Wellbeing and distress in young people with chronic conditions: how do positive psychology variables relate to mental health outcomes?
The aim of this study was to determine the unique and shared contributions of various positive psychology constructs (gratitude, optimism, hope, self-compassion, self-efficacy, and emotion regulation) to wellbeing and distress outcomes in young people living with a diverse range of chronic health conditions.
