Prader–Willi syndrome (PWS) is a complex, genetically based disorder; caring for a family member with a disability such as PWS brings significant challenges to the whole family. However, no research has been conducted focusing on the impact of PWS in the dynamics of Latino families. This qualitative study explored the challenges and need for support services among Latino families of children with PWS. Findings of the study suggest the need for support services geared toward the whole family unit to help members cope with daily challenges at home.
