Do you have a child aged between 2½ and 5 years who has a developmental delay (excluding ASD)? If so, we’d like your help with a research project. This project will be comparing two questionnaires that measure behavioural, emotional, and communication problems in children, in order to inform better assessment and treatment.

Participation involves completing paper-and-pencil questionnaires, which will take approximately 20 minutes in total. All responses are anonymous. To take part, simply email your name and postal address to Sonya Errington at The information sheet, questionnaires and stamped self-addressed envelope will then be mailed to you.

If you’d like more information, please contact Sonya Errington at

Thank you!
