Are you an adult who stutters? 

Are you interested in receiving treatment and willing to participate in a treatment study?

The Australian Stuttering Research Centre is investigating the effect of combining intensive speech practice designed to reduce stuttering with an Internet Cognitive Behaviour Therapy program to address speech-related anxiety.

What is involved?

An assessment will be completed to collect information about you and your stuttering. There are potentially two components to the treatment 1) a stuttering reduction component (speech treatment) and 2) an anxiety reduction component (Internet CBT program). All participants will receive the speech treatment but only about half will be offered the Internet CBT program. This will be randomly decided. However, if you are not offered the Internet CBT program in the first instance, you will be able to have access to the same program after all data has been collected 12 months later. 

The ethical aspects of this study have been approved by the HREC of the University of Sydney [protocol number: 2016/393]. 

For further information, please see the Australian Stuttering Research Centre website.


You may be eligible to participate in this study if you:

  • Are aged 18 years or older
  • Have a confirmed diagnosis of stuttering by a speech pathologist
  • Experience social anxiety
  • Have good spoken English as well as good skills for reading and writing English
  • Have unlimited access to a computer with Internet connection.
