The study will include 90 youth who have a chest wall surgery or a spinal fusion surgery at the Alberta Children's Hospital. They will be recruited at the Alberta Children's Hospital. There will be pain tests in the form of surveys 1-3 weeks before surgery, pain monitoring in the hospital for a couple of days, pain monitoring 1-2 weeks after surgery, a clinic visit 2-4 weeks after surgery for a memory reframing session, and pain monitoring 6 weeks after surgery in the form of a telephone interview.
