Internet-based cognitive behavioural therapy for tinnitus

Participants are needed for our study to better understand if the mode of delivery correlates with therapy effectiveness.

We are looking for people who are experiencing tinnitus to receive internet-based cognitive behavioural therapy (iCBT) through an engaging virtual coach, delivered through an app installed on your mobile phone. The virtual coach, called Tinnibot, will help you better manage your tinnitus and its effects using a chat conversation interface.

The aim of our study is to understand the benefit of human support through video conferencing, in addition to Tinnibot, the virtual coach.

What’s involved?

You will be asked to complete eight weeks of the iCBT program using an app installed on your mobile phone. Before the start of the program you will be invited to complete an online eligibility questionnaire.

If you meet the eligibility criteria, we will book an appointment to explain the study to you and to complete an audiological assessment, and a series of questionnaires.

We will conduct the session in a dedicated testing room located in the Speech Science Group Research Rooms, School of Psychology, Faculty of Science, University of Auckland Grafton campus:

Grafton, Park West
Lower Ground (LG), Building 507
85 Park Road
Auckland Central, 1023

During the eight week program, you will interact with the virtual coach for 5 to 15 minutes per session.

There will be two groups of participants. The first group will only be completing the iCBT program with the virtual coach. The second group will receive human-delivered counselling through video call in addition to the iCBT program delivered via the virtual coach. The counselling sessions will be scheduled every fortnight (four sessions of 30 minutes). The counselling will be delivered by Dr Cara Wong, who is contracted for the study. You will be randomly assigned to one of the two groups.

At the end of the eight weeks program, and again two months after the end of the program, we will ask you to complete another series of questionnaires.
