Research project: Attachment disorders in childhood: Validation of the ETRADD-Q

A message from Sébastien Monette, Ph.D.-Psy.D. at CIUSSS du Centre-sud-de-l’île de Montréal:

We would like you to take part in a research project that we are conducting on Reactive Attachment Disorder (RAD), a psychological disorder that some children develop after experiencing adverse living conditions at an early age. The project aims to validate a questionnaire to be used by mental health professionals to help assess and diagnose this disorder in children 5 to 13 years of age. To this end, we need to collect data on adopted children and children receiving child protective services (in foster care). Your participation would help not only to validate the diagnostic tool in question but ultimately also to ensure that children receive services better suited to their needs.

Your involvement

Your participation would entail taking about 30 minutes to complete an online questionnaire regarding the behavior of your adopted child or of a child in your care. Your data would remain strictly anonymous. If you are interested, we would ask that you complete the questionnaire within one month of receiving this letter.

Benefits of your participation

You would derive no direct personal benefit from participating in the research project. However, your participation would help the clinical and scientific community to better understand RAD and to provide professionals with a reliable and validated assessment tool to use in their practice. Finally, participating in the project poses no risk to you.

Thank you for your consideration! Your participation would make a world of difference for vulnerable children.
