Sue Diggles joined the CPPAQ Board in 2014 and sadly passed away in 2015. To recognise her outstanding contribution to CPPAQ and the child protection field in Queensland, the Brisbane Catholic Education Office sponsors an annual practice paper in her name.

Topic : Best practice investigative interviewing of children and young people

About this paper

Investigative interviewing is the process of eliciting information from a person about an event or situation, in order to facilitate decision-making. Young people – including very young children – are capable of providing reliable information when questioned using the appropriate technique. This presentation provides an overview of what constitutes best practice investigative interviewing and how this can be achieved. Topics include: guidelines for establishing rapport; issues related to children’s suggestibility and assessing credibility; practical strategies for structuring the interview, lowering inhibition and eliciting accurate and detailed disclosures.
