The Centre has a whole section in the Positive Psychology Resources section of the website dedicated to resilience. Many relevant themes are also included in the PP Resources section on confidence, optimism and mindset. Remember to make sure you don't simply read the overview essay but also read the summaries of evidence and look at some tools, tips and techniques in the Flourishing Lives section.
Information on resilience is also available in the Centre's publication Creating Confidence: A Handbook for Professionals Working with Young People. This publication can be accessed from the menu on the left hand side
