The GBQ+ Community Periodic Surveys (GCPS) are repeated, cross-sectional surveys of gay, bisexual and queer men (cis and trans), and non-binary people who have sex with gay, bisexual and queer men. They are a key part of Australia鈥檚 behavioural surveillance system for HIV, monitoring sexual practices, drug use and patterns of testing for HIV and other STIs. The surveys were formerly known as the Gay Community Periodic Surveys.

Initiated in 1996, the GCPS are conducted in seven states and territories (all except the Northern Territory). The GCPS deliberately target men and non-binary people who are socially and sexually involved with gay, bi, and queer men, and recruit participants at LGBTQ community venues and events, sexual health services, and online.

The surveillance system relies on a longstanding collaboration between CSRH, The Kirby Institute, state health departments, and national and state community organisations. Recruitment is typically coordinated in each state/territory by a local community organisation. The results of each survey are published in an individual state or territory report, and national trends are presented to monitor National HIV Strategy targets.

The GCPS team have been awarded NHMRC Partnership Project funding during 2021-26 and 2026-31. This additional funding聽will allow the team to increase recruitment and data collection from underserved populations and respond more effectively to new health threats and emerging prevention technologies.

What is the research study about?

You are invited to participate in an online survey of gay, bisexual, and other men who have sex with men and non-binary people who have sex with gay, bisexual, and queer men. The survey monitors trends in sexual behaviour, relationships, the use of different HIV prevention strategies, drug use and testing for HIV and other sexually transmitted infections. The results are used to guide HIV and sexual health programs.

Who is conducting this research?

The study is being carried out by researchers from the Centre for Social Research in Health and the Kirby Institute at the University of New South Wales. The research is supported by reference groups in each state and territory where the survey is conducted. The reference groups include representatives from gay community and HIV organisations and health departments.

Research Funder: This research is funded by state and territory health departments, the Australian Government Department of Health, Disability and Ageing, and the National Health and Medical Research Council.

Inclusion/Exclusion Criteria

Participation is open to men (cisgender or transgender) who identify as gay or bisexual or have had sex with another man in the past five years and non-binary people who have had sex with gay, bi or queer men in the past five years. You must be at least 16 years of age and live in Australia. You should only complete the survey once each year. Women and temporary visitors to Australia are not eligible to take part.

Do I have to take part in this research study?

Participation in this research study is voluntary. If after reading this information you decide you want to take part in the study, you can complete the survey. If you do not want 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 study (by closing your browser window).

What does participation in this research require, and are there any risks involved?

The questionnaire takes 10-15 minutes to complete. Complete it by yourself. The survey can be completed anonymously, if you do not include contact details like your email address. Answer all the questions that are relevant to you. You can skip over optional questions you do not wish to answer.

The main risks associated with the research are discomfort in answering personal and explicit questions about sex, relationships, drug use or HIV, and the inconvenience of completing the questionnaire. It is possible that you may experience distress because of the questionnaire topics. If you experience discomfort or distress, you may stop and withdraw at any time. We have provided a link to an advice and support service below.

What are the possible benefits to participation?

There are no direct benefits for participants (such as remuneration). The study findings may have indirect benefits by improving HIV and sexual health services for gay and bisexual men and non-binary people.

What will happen to information about me?

Your survey responses are stored in a secure database at the university, only accessible to the research team or qualified researchers who submit a request to analyse the data to the research team. No identifying information about you is stored in the survey database, so you cannot be identified.

Because the surveys track trends over time, the older survey data is maintained in the database for analysis. In future, the older survey data may be made available in a deidentified form in a publicly accessible data archive, accessible to qualified researchers.

How and when will I find out what the results of the research study are?

Results for each survey round are published in reports on this web page, and by our partner organisations. Results are presented in peer-reviewed journal articles and at national and international conferences (some are listed on this web page). Feedback sessions are held by local gay community and HIV organisations. We may also report the survey findings in local community media or the national media.

What if I want to withdraw from the research study?

Your decision whether or not to participate will not prejudice your future relations with the University of New South Wales or any other organisation involved in this survey. If you decide you do not wish to participate while you are completing the questionnaire, please exit the survey and close your browser window. Because the questionnaire is anonymous, we will not be able to remove your answers later because we will not be able to identify you or your responses.

What should I do if I have further questions about my involvement in the research study?

The person you may need to contact will depend on the nature of your query. If you have an immediate question about participation while we are recruiting, you may contact Dr Timothy Broady, a member of the research team by email (t.broady@unsw.edu.au) or by phone (02 9385 1086).

If you require further information regarding the study or would like to provide feedback on it, you can contact the study鈥檚 chief investigator: Professor Martin Holt, Centre for Social Research in Health, 91色情片 Sydney, 02 9385 6410, m.holt@unsw.edu.au.

What if I have a complaint or any concerns about the research study?

If you have a complaint regarding any aspect of the study or the way it is being conducted, please contact the 91色情片 Human Research Ethics Coordinator (02 9385 6222, humanethics@unsw.edu.au, reference iRECS4718).
