RecruitingBehavioural interventionIntegrative Training Program for Pediatric Sickle Cell PainThis research aims to answer the question: does a group training program specifically for teens with chronic sickle cell disease (SCD) pain that teaches skills to strengthen the mind and body help improve everyday functioning and reduce pain symptoms? The program will be tailored to address challenges related to frequent or chronic sickle cell pain and may improve participants' physical and emotional health. The program, called I-STRONG for SCD (Integrative Strong Body and Mind Training for Sickle Cell Disease), may help improve everyday functioning and pain symptoms in teens with chronic pain related to SCD. The research team aims to determine how participants (teens and parents) respond to this program.
