Findings from this survey will help the PWSA UK advocate for the needs of infants and young children with PWS and the needs of their families. All data collected from this survey will be anonymised and initially stored and analysed using a secure database at the University of Cambridge. On completion of the analysis the data will be transferred to PWSA UK and will be stored securely in a manner that is compatible with the Data Protection Act. The results published in the report will be anonymised group data and individuals will not be identifiable and would not be identified unless explicit permission had been given.
