Young children diagnosed with Medulloblastoma experience limited access to enriched environments due to lengthy hospitalizations and show significant developmental delays, making strong parent-child interactions critical to promote cognitive, emotional and social developmental skills.

Dyads with children being treated for Medulloblastoma had Reciprocity scores significantly higher (407±19.67) than those with children without a medical condition (345.02±8.54, p=0.01), while all other domain scores were not significantly different between the two groups.

As reciprocity has been shown to strongly support child cognitive and social-emotional developmental skills, our findings suggest that children with Medulloblastoma are in a good position to benefit from interventions designed to improve developmental skills. Using both SI and PICCOLO appears to provide a comprehensive understanding of parent-child dynamics in children with Medulloblastoma.
