IntraHealth International, in partnership with ideas42, implemented the Scale-Up and Capacity Building in Behavioral Science to Improve the Uptake of Family Planning and Reproductive Health Services (SupCap) project, funded by the William and Flora Hewlett Foundation, to address the challenges of PPFP uptake. We implemented the SupCap project within the USAID-funded Regional Health Integration to Enhance Services in Eastern Uganda (RHITES-E) Activity led by IntraHealth. SupCap employed a behavioral design process to address barriers women and men face in using contraception during the extended postpartum period.
