3. What is the purpose of the study?

You are invited to participate in a research study. This information sheet provides you with information about the research study. The Principal Investigator is Associate Professor Wong Mee Lian from the Saw Swee Hock School of Public Health, National University of Singapore. Please read the information below before deciding to take part in this survey.

This study involves an anonymous survey. In Singapore, increasing number of men are getting HIV and other STDs (diseases that are transmitted by sexual intercourse) through unprotected sex with sex workers and casual sex with women. The purpose of this study is to help us understand your sexual behaviours, your attitudes and beliefs about condom use, and your health-seeking behaviours, meaning, things you do to take care of yourself. The knowledge we gain from this survey will help us plan health programmes to protect Singaporean men from getting HIV and STI infections.

4.1. Who can participate in this research?

To participate in the study, you must be between 21 to 70 years old, male, Singapore citizen or a permanent resident.

In addition, you must have visited brothels or entertainment establishments, and you must have had sex with female sex workers, or casual partners (non-paying partners who are not your wife or longstanding girl friends) in the past year.  

4.2. What is the expected duration of my participation?

 The survey will take about 20 minutes.

4.3. What is the duration of this research?

 This quantitative study will take 6 months to complete.

5. What is the approximate number of participants involved?

A total of 300 men who have sought sex through the Internet will be invited to participate in this survey, which is part of a larger research project which investigates STI/HIV risk behaviours among men from different venues in Singapore. The whole research study aims to study 1200 men in Singapore.

6. What will be done if I take part in this research?

You will be asked to complete a questionnaire that includes a series of questions about demographic information. After that, you will be asked about your sexual behaviours with your regular partner (wife/girlfriend), casual partners, and/or commercial sex partners in the past year. After sexual history, you will be asked to complete questions on your health-seeking behaviours.
