What is this study about?

The Nipissing District Developmental Screen (NDDS)-2011 is a short survey that parents complete and is used by parents, doctors or healthcare professionals to look at a child’s emotional, social, motor and cognitive development. In 2009 to 2011, we completed the Psychometric Assessment of the NDDS Study (PANS), where we examined the usefulness of the revised version of the NDDS (NDDS-2011) and asked parents what they thought about it. In this study, parents told us that for some questions, it was hard to come to a decision about their child’s development using only ‘yes’ and ‘no’ responses that were available on the NDDS. For this study, NDDS Alternate Responses Study (NARS), additional responses of ‘sometimes’, ‘not sure’ and ‘have not tried’ have been added to the NDDS.

Would my child and I be able to take part?

We are no longer recruiting for this study.


What would my child and I have to do?

Families in this study were asked to participate in a ~2 hour appointment with a trained research assistant.

At the appointment, a trained research assistant guides children through various activities using well-established tools that look at a child’s development and abilities. Parents were also asked to complete the NDDS-2011 with the additional responses as well as other well-known surveys.
