Background: People with Down syndrome (DS) are predisposed to challenges with executive functions (EF), which are crucial for adaptive outcomes and academic success. Early interventions targeting EF are therefore critical. The present study analysed Italian data on the acceptability, enjoyability and household implementation of EXPO (EXecutive function Play Opportunities), a novel caregiver-mediated intervention designed to strengthen EF skills in young children with DS. Methods: Nineteen families of children aged 42-93 months participated. Caregivers completed questions via a smartphone app and provided feedback through Mid-Point and Exit questionnaires. Results: Implementation and enjoyment remained consistent throughout the intervention. Caregivers reported positive effects of EXPO on children's everyday life skills and found the coaching sessions beneficial for successful program implementation. Conclusion: The EXPO intervention is acceptable and enjoyable for both caregivers and children, with caregivers reporting perceived improvements in children's everyday life skills after participating in the program.
