Part 1 What does my participation involve?

1 Introduction

You are invited to take part in this research project. The research project is aiming to evaluate an intervention for people who hear voices (sometimes referred to as 'auditory hallucinations').

This Participant Information and Consent Form tells you about the research project. It explains the procedures involved. Knowing what is involved will help you decide if you want to take part in the research.

Please read this information carefully. Ask questions about anything that you don't understand or want to know more about. Before deciding whether or not to take part, you might want to talk about it with a relative, friend or healthcare worker.

Participation in this research is voluntary. If you don't wish to take part, you don't have to. You will receive the best possible care whether you take part or not.

If you decide you want to take part in the research project, you will be asked to sign the consent section. By signing it you are telling us that you:

  • understand what you have read;
  • consent to take part in the research project;
  • consent to participate in the research processes that are described;
  • consent to the use of your personal and health information as described

You will be given a copy of this Participant Information and Consent Form to keep.

2 What is the purpose of this research?

This project aims to test the effects of a six-session intervention aiming to treat voice hearing experiences that are related to past traumatic events. The intervention is called 'imaginal exposure' and is a type of psychological treatment that has been shown to help with psychological difficulties after traumatic events (often known as 'trauma-focussed treatments'). Imaginal exposure involves talking through traumatic events in order to process the emotions and meanings of the events and reduce their impact.

Recent research has found that voice hearing experiences are often related to past traumatic events. Traumatic events may play a role in the onset or maintenance of some people's voice hearing experiences. Because we do not yet know how helpful trauma-focussed treatments are for treating voice hearing experiences, we have developed a project in which we can further understand how acceptable and effective these treatments might be.

This research has been initiated by the Principal investigator named on page one. The results of this research will be used by the researcher Rachel Brand to obtain a Doctor of Philosophy (PhD) and the researcher Natalie Feary to obtain a Masters in Clinical Psychology (MPsych).

3 What does participation in this research involve?

The intervention

The intervention being tested in this study is a six-session imaginal exposure intervention. You will meet with a Clinical Psychologist for weekly sessions at the Voices Clinic at Swinburne University, Hawthorn campus. Each session will last for 90 minutes. The sessions will involve identifying traumatic events in your life that may be related to your voice hearing, understanding how they might be related, and then talking through the events repeatedly, in detail, in order to process the emotions and meaning of the events. You will also be asked to listen to audio recordings of sections of the sessions at home, several times each week. These audio recordings will be made using your smartphone or an audio recorder provided by the research team. These audio recordings will not be kept by the research team, and will be for your use only. You will be supported to make these recordings secure (e.g. using password protection) to protect your privacy.

You can continue to receive the usual treatment and support from your mental health services during the course of your involvement in this project without restriction.


As a first step, you will speak with a member of our research team to make sure that you are eligible to take part in the study. If you are eligible and agree to participate, you will meet up with a member of our research team in the next week or two to sign the consent form and to have an initial baseline interview before you start the intervention. The baseline interview will involve completing some interviews and questionnaires about your current mental health, your experience of hearing voices, and any traumatic events that you have experienced and the impact this has had on you. You will also be asked to provide some demographic information, such as your age and education. This interview will take approximately three hours. We expect that each of the interviews can be completed in one meeting, but they could be held over more than one meeting, if needed. If you have a mental health clinician currently involved in your care, the research team will contact them after your baseline interview to inform them of your involvement in the study and ask if they have any concerns about you taking part.

After this interview, if you are eligible to continue in the study, you will be asked to use a smartphone app to monitor your voice hearing experiences and other trauma-related symptoms for the next six days. The app will prompt you to complete a 1-2 minute questionnaire 10 times each day. You will be loaned a smartphone to complete these assessments.

You will start the intervention 1-2 weeks after the baseline interview. In your first intervention session you will also repeat a short assessment of your experience of hearing voices.

You will meet with a member of our research team for another interview at the end of the intervention, and one month later. Each follow-up assessment interview will take approximately 90 minutes. At the end of the intervention, you will also be asked to conduct another six days of monitoring using the smartphone app. The smartphone app assessment will be the same as that conducted in week one.

In addition, you will be given a questionnaire about your experience of the treatment. You will then have the option of taking part in a more in-depth interview about your experiences of the treatment, if you are interested in doing this.

Optional parts of the study

The following parts of the study are optional. We will ask you whether you would be willing to do these when you sign the consent form.

Audio recording. If you give your permission, we would like to make audio recordings of the assessments and intervention sessions. Assessment session recordings will be checked to make sure that ratings are being completed consistently. Intervention session recordings will be randomly checked to make sure that the interventions are being delivered correctly, and to help discover what aspects of each intervention are most useful. A portion of the audio recordings from the second and final treatment sessions will be transcribed by a researcher. The part of the recording that will be transcribed will be your first imaginal exposure exercise from these sessions. The written version of this will be used to rate how your memory of the trauma has changed over treatment. You can change your mind about audio recording at any time. If you do change your mind, you can request that the recordings that have already made be erased.

4 Costs and reimbursement

There are no additional costs associated with participating in this research project. The interventions will be provided to you free of charge. You will not be reimbursed for the intervention appointments. However you will be reimbursed $30 at each assessment (there are five core assessments in total) towards costs such as travel, parking and phone data.

5 Can I take part in this project?

If you would like to take part in this study you need to:

  • be aged 18-75
  • have experienced voice hearing for at least 6 months
  • currently experience voices at least twice weekly
  • have experienced events in your life that might be considered to be traumatic (e.g. experiencing an event or events where your life was in danger, or being significantly mistreated, neglected or abused as a child, or having someone repeatedly bully, humiliate or intimidate you)
  • think that your voice hearing experiences are related to the above traumatic events in some way
  • be willing and able to undertake a treatment that involves talking about the above traumatic events in detail with a Clinical Psychologist
  • have sufficient fluency in English

You will not be able to take part in this study if:

  • you have had a change in psychiatric medication in the past month or are planning a change in the next three months
  • you have voices which are primarily caused by substance use, or you have substance dependence issues which may interfere with your participation
  • you have an intellectual disability
  • you are currently at acute risk of harming yourself or other people
  • your treating team identify that undertaking this treatment would pose a serious risk to your safety or the safety of others

6 Other relevant information about the research project

This is a project led by Swinburne University of Technology.

We are expecting 15 participants to take part in this project. Participants are being recruited through the Voices Clinic at Swinburne University, and through advertising at a range of mental health services and online.

7 Do I have to take part in this research project?

Participation in any research project is voluntary. If you do not wish to take part you do not have to. If you decide to take part and later change your mind, you are free to withdraw from the project at any stage.

If you do decide to take part, you will be given this Participant Information and Consent Form to sign and you will be given a copy to keep.

Your decision whether to take part or not to take part, or to take part and then withdraw, will not affect your routine treatment, your relationships with those treating you, or your relationships with Swinburne University, the Voices Clinic, or your local mental health service.

8 What are the alternatives to participation?

You do not have to participate in this research project to receive treatment or support from your mental health services. The intervention offered through this project is additional to the standard treatment you are receiving. If you choose not to take part in this study but would like to receive the standard treatment at the Voices Clinic, you will continue your treatment with the Voices Clinic as usual.

9 What are the possible benefits of taking part?

We cannot guarantee or promise that you will receive any benefits from this research. However, we hope that this project may be able to benefit you by receiving assistance from a Clinical Psychologist to help you to reduce the impact that past traumatic events may be having on your mental health generally, and on voice hearing specifically.

10 What are the possible risks and disadvantages of taking part?

There are no risks of physical harm involved in participating in this study.

Discomfort or distress

If you agree to participate in this research, you will be asked questions about your mental health and well-being and to briefly outline your experiences of traumatic events. In general, it is not anticipated that discussion of these topics would give rise to any long lasting negative effects. However, where experiences have been of a traumatic or difficult nature, there may be a possibility that recalling these events may cause you to feel upset or distressed. If you do feel distressed when being interviewed, please let the researcher know. If you feel uncomfortable talking about difficult subjects, then at any time, you are free to say you don't want to talk about them, to have a break, or to discontinue your participation. The imaginal exposure treatment involves talking through your traumatic experiences repeatedly and in detail with a Clinical Psychologist. This treatment may lead to short term distress, and you will be offered support from your Clinical Psychologist in managing this. If you do find this aspect of the treatment too distressing, you are free to discuss this with your psychologist, a member of the research team, or to withdraw at any time without any consequences for your ongoing treatment at the Voices Clinic.

At the beginning, we will ask you to nominate a designated contact person who is not involved in this project. This could be a nurse, doctor, case manager or other support worker, whom you have current contact with, or alternatively a family member or friend. This is so that if you wanted any further support after any of the appointments, you know you can speak to that person. If we had any concerns about you, we would also encourage you to speak to that support person, and we could help you to do that. Of course you can also speak to a member of the research team, and the phone numbers for the research team can be found in Section 18.

Other risks

During the research project, if new information about the risks and benefits of the project become known to the researchers, you will be told about this new information, and one of the researchers would discuss whether this new information affects you.

11 What if I withdraw from this research project?

If you do withdraw your consent during the research project, the researchers will not collect additional personal information from you, although personal information already collected will be retained to ensure that the results of the research project can be measured properly, and to comply with law. You should be aware that data collected up to the time you withdraw will form part of the research project results. If you do not want your data to be included, you must tell the researchers when you withdraw from the research project.

12 What happens when the research project ends?

We expect that the research project will be completed by late 2019. On completion of the project, we will provide a plain language report of the project results that we can send by post or email, if you request for this.

Part 2 How is the research project being conducted?

13 What will happen to information about me?

No member of the research team will receive a personal financial benefit from your involvement in this research project (other than ordinary wages).

16 Who has reviewed the research project?

All research in Australia involving humans is reviewed by an independent group of people called a Human Research Ethics Committee (HREC). The ethical aspects of this research project have been approved by the HREC of Swinburne University.

This project will be carried out according to the National Statement on Ethical Conduct in Human Research (2007). This statement has been developed to protect the interests of people who agree to participate in human research studies.

17 Future contact

Our study into ways of helping people with the experience of hearing voices is ongoing. We may do a follow-up study to look at how people's experiences change over time, or do other studies on the experience of hearing voices. Therefore, we would like to obtain your permission to contact you in the future about other studies. If you provide your permission for us to contact you again, the Principal Investigator will retain your contact details and store them securely, separately from any data you provide. If we were to contact you, we would call you and ask if you wanted to participate in another study. You would be under no obligation to participate in any other study. You can also change your mind about being contacted again, and we will delete your contact details on request. You will be asked to indicate your willingness for this at the end of this consent form.
