This study looks at helping young people with sickle cell disease (SCD) manage their pain better. SCD is a condition where the blood doesn't carry oxygen well, causing pain. The study tests a method called cognitive behavioral therapy (CBT), which is a talking therapy that helps people change how they think about pain. There are two types in this study: digital CBT with a peer supporter, and digital CBT without one. They will use an app called CaRISMA to help with this. The study will last for a year, with check-ins at 3, 6, and 12 months. They want to see if CBT can reduce pain and the use of pain medications like opioids.

• The study includes young people aged 16-30 with SCD who experience chronic pain.
• Participants need to have a mobile device with internet access to use the app.
• The study offers two versions of CBT, one with peer support and one without.
