PROJECT NARRATIVE This administrative supplement is part of the parent grant “Implementing and evaluating mHealth pain coping skills training interventions to improve self-management of chronic pain in cancer survivors in real world clinical practice settings”, also known as IMPACTS. This supplement will provide additional funding to pay site accrual fees and purchase participant incentives resulting from an increase in sample size (from 438 to 456 participants) and to account for an increase in site accrual fees for NCORP community sites in the time since the IMPACTS study was funded.
