Culturally Adapted Mobile Treatment of Chronic Pain in Adolescent Survivors of Pediatric Cancer

This is a prospective study that will conduct a series of focus groups with non-Hispanic Black and Hispanic childhood cancer survivors to obtain their input on culturally adapting a mobile CBT program for chronic pain and tDCS procedures. Once this adaptation process is completed, the investigators will conduct a feasibility trial with non-Hispanic Black, Hispanic and non-Hispanic White survivors of childhood cancer with chronic pain. The feasibility study will assign eligible participants to either culturally adapted mobile CBT + active tDCS to the dorsolateral prefrontal cortex or culturally adapted mobile CBT + sham tDCS. We anticipate approximately 60 participants for the focus groups and approximately 30 participants for the feasibility study for a total of about 90 participants.

Survivors of pediatric childhood cancer are at-risk for developing chronic pain. Cognitive behavioral therapy (CBT) is an effective non-pharmacologic treatment for chronic pain, and can be delivered remotely to reduce access barriers. However, these programs have not been adapted to be culturally sensitive to underserved populations thus limiting their reach, usefulness, and uptake. The investigators propose to culturally tailor an established, evidence-based mobile CBT program for chronic pain to Black and Hispanic adolescent survivors of childhood cancer. Once the program is fully adapted, we propose to pair the culturally adapted mobile CBT program with remotely delivered transcranial direct current stimulation (tDCS), which may enhance pain control in survivors. The investigators will conduct a 6-week feasibility study in a racially/ethnically diverse sample of non-Hispanic White, non-Hispanic Black, and Hispanic adolescent survivors of pediatric childhood cance with chronic pain using culturally adapted CBT paired with remote tDCS. Study results will inform the development of a randomized clinical trial.
