Participant information & consent form

Pilot study to prevent the exacerbation of anxiety and alcohol use comorbidity through brain training

(1) What is this study about?

You are invited to take part in research study that aims to examine the feasibility, acceptability and efficacy of an age-appropriate, online brain training program for young Australians who experience anxiety symptoms and problematic alcohol use. 

Most treatments that currently exist for anxiety and alcohol use problems seek to change unhealthy thoughts and behaviours at a conscious or explicit level (e.g. Cognitive Behavioural Therapy). However, many people indicate that their anxiety and alcohol consumption is not always a conscious choice. Supporting this, there is accumulating evidence that anxiety and drinking are affected by processes operating at a subconscious, implicit level. For instance, people with alcohol use problems have an implicit “approach bias”, where they are automatically drawn to approach or seek alcohol. An approach bias can be triggered very quickly, so people aren’t even fully aware they’re being influenced by it. This can make drinking very difficult to control. Thankfully, scientific research has shown that these subconscious, automatic thoughts and behaviours can be changed via “brain training” programs (known as Cognitive Bias Modification). As with other habits, such as typing, driving or cycling, repeated exercise (or in this case repetitive completion of a brain training task) allows an individual to develop new automatic thoughts and behaviours. In turn, by re-training these maladaptive subconscious tendencies, we aim to reduce young people’s anxiety and drinking behaviour.

(3) What will the study involve for me?

If you decide to take part in the research study, you will be required to complete the steps below:

Step 1:

Complete a brief 10-minute survey comprising questions that will be used to determine whether this study is suitable for you. If the study is not suitable for you, we will provide you with a list of alternative options for seeking assistance and support.

Step 2:

If you are eligible to participate, you will be asked to complete an additional survey about your experiences with anxiety and other mental health concerns and experiences (e.g. sleep), your experiences with (and expectations around) drinking alcohol and/or taking other drugs. You will then be asked to complete a cognitive assessment that will measure your subconscious, automatic tendencies to think in certain ways. These will take approximately 45-50 minutes (combined) to complete and you will receive a $30 Prezzee gift voucher once you have completed both tasks.

Step 3:

Once the initial survey and cognitive assessments are completed, you will be randomly allocated to one of three groups. Random allocation means that neither you nor the study team choose which program you receive; this is determined by chance (like a toss of a coin). You will have a chance of receiving either:

  1. The ‘integrated’ brain training intervention, which re-trains both anxiety and alcohol biases within each session (i.e. sessions comprise 50:50 focus on anxiety and alcohol), plus treatment as usual
  2. 1.    The ‘alternating’ brain training intervention, which re-trains anxiety biases in one session and alcohol biases in the next session (i.e. there are 10 sessions, with 5 sessions focused on anxiety and 5 sessions on alcohol), plus treatment as usual
  3. Treatment as usual only

Step 4:

Regardless of which condition you are randomly allocated to, you will be asked to complete a brief (5-minute) assessment about your anxiety symptoms and alcohol use each week. As a thank you for your time, you will receive a $5 Prezzee e-gift voucher for each of the 10 assessments, with an accumulated voucher paid at the end of the 5-week period.

Step 5:
Lastly, you will be asked to complete an online survey and cognitive assessment 6-weeks and 3-months after the initial survey. These follow-up surveys and cognitive assessments will take approximately 45-50 minutes (combined) to complete, and will allow us to assess your progress and any benefits of the program. We will also ask for your feedback about the program you participated in. Participation in the follow-up surveys/cognitive assessments is voluntary. However, to help us accurately measure the effects of the brain training, we encourage you to complete the these tasks regardless of which group you were in or whether your anxiety and/or drinking has changed. You will receive a $30 Prezzee gift voucher at each timepoint.

If you were allocated to the treatment as usual only group, you will be offered the opportunity to receive one of the brain training programs following completion of the 3-month follow-up survey.

(4) How much of my time will the study take?

We expect the online surveys and cognitive assessment will take approximately 45-50 minutes to complete (combined) at each of the three time points (i.e., the initial assessment, 6 weeks later, and 3-month later). The brain training intervention consists of 10 x 20-30minute sessions, designed to be completed twice per week over a 5-week period.

(5) Do I have to be in the study? Can I withdraw from the study once I've started?

Being in this study is completely voluntary and you do not have to take part. Your decision whether to participate will not affect your current or future relationship with the researchers, the funders, members of your treatment service or anyone else at the University of Sydney or other institutions conducting this research. 

If you decide to take part in the study and then change your mind later, you are free to withdraw at any time without giving a reason. Should you decide to discontinue your participation in the project at any time, you may contact the research team directly via email ( or phone (02 8627 9032) and tell them you no longer want to participate. After you withdraw, the researchers will not collect additional personal information from you. However, personal information already collected before you withdrew 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.

(6) Are there any risks or costs associated with being in the study?

The brain training tasks involve viewing images of alcohol and objects related to alcohol use. The questionnaires include questions about recent use of alcohol and other drugs. There is some risk that the tests or surveys may therefore be upsetting or increase craving for alcohol. We believe this risk is small, but if you feel distressed or experience increased cravings, please let the researcher know so they can provide support or arrange support

There is also some risk that modifying alcohol use will be associated with withdrawal symptoms and an exacerbation of symptoms of anxiety. In fact, if your alcohol use is high there are also some medical risks, and we advise seeking medical advice before making any significant changes to your current alcohol use. Some people may find also it distressing to talk about or confront psychological issues, including anxiety symptoms. If you are concerned or become distressed at any stage, we would encourage you to contact the services listed at the end of this information sheet, where you may obtain additional services and 24-hour support.

There are no costs to you associated with participating in this research project. If you choose to participate you also have the right to stop completing the survey, cognitive assessments or brain training at any time and withdraw from the study.

(7) Are there any benefits associated with being in the study?

We cannot guarantee or promise that you will receive any benefits from this research. However, possible benefits of participating in the brain training may include a reduction in anxiety and reduced alcohol consumption. 

As a thank you for your time and involvement in our research, will provide you an AUD$30 Prezzee e-gift card at the completion of the survey and cognitive assessment at each of the three time points. If you withdraw prior to the completion of one of the survey/cognitive assessment, no reimbursement will be provided. In addition, you will be asked to complete two weekly 5-minute assessments of your anxiety and alcohol use, for which you will receive a $5 Prezzee e-gift voucher per completion (10 total), with an accumulated voucher paid at the end of the treatment period (maximum $50 voucher).
