[Genetic Investigations in Children with Developmental Disorders, Intellectual Disability and/or Epilepsy - The...

Shared decision-making is indispensable when it comes to molecular genetic investigations, but data on the expectations of the parents is scarce.

Using a step-by-step approach we initially performed free in-depth-interviews with five parents on which base we developed a half standardized questionnaire. This questionnaire was then applied in interviews with 30 parents of children with intellectual disability, autism or epilepsy subject to genetic examination.

Pre-diagnostic discussions are challenging for the parents in an intellectual as well as emotional way. The most important general aspects are diagnosis and therapy. Self-assessment of prior knowledge is very variable and many parents expressed problems in understanding. During the conversation parents rate the following specific aspects as "very important" or "important": findings of unclear relevance, incidental findings, psychic consequences, prognostic aspects, possible therapeutic interventions. 10 Parents did not have any school-degree and 20 parents were not native speakers.

All parents express a high need for information covering almost all aspects of the investigation. Communicational hurdles pose additional challenges leaving a large room for improvement. Trustworthy internet-based information systems in different languages including plain language could be a first step.
