Survey about achondroplasia
We have designed a questionnaire with the purpose to better know the population connected to achondroplasia.
The questionnaire is optional and anonymous. The data obtained will be used for statistical purposes and to better understand the natural history of achondroplasia. Please consider answering.

The Brod Group started in 2019 a large multinational research on achondroplasia, interviewing hundreds of parents of children with achondroplasia by phone and conducting focus groups, in several countries. Beyond Achondroplasia has been supporting this research since then. By now, two papers have been published and posters have been presented at conferences.

As part of this large research project, The Brod Group, developed a new study, an online/web-based research survey.
Parents of children with achondroplasia aged 2 to 11 years old, from Australia, New Zealand, Spain, and Portugal are invited to participate. Other countries will follow.

Online survey description

  • The survey will take about 45 minutes to complete. This survey allows breaks and saving the responses for 1 week.
  • Parents will be invited for a follow-up online survey 2 weeks later, which will take 5-10 minutes.
