Pride-Based Violence, Intoxicated Sex, and Polydrug Use: A Vocational School Study of Heterosexual and LGBT Students in Bangkok | BMC Psychiatry

To taste

This study included 638 first-year vocational students (equivalent to 10th grade) from four vocational schools in Bangkok, two private schools and two public schools. An online questionnaire was used, accessible to participants via desktop computers, tablets and smartphones. The Mahidol University Social Science Institutional Review Board (MUSSIRB) reviewed and approved the study (Certificate of Approval No. 2017/161.2607). For participants under the age of 18, OMRSSE approved parental consent waivers, based on our previous study on proxy consent and parental consent waivers [19]. Prior to study enrollment, we provided a detailed explanation of the risks and benefits of the study to students. All students provided assent/consent to participate verbally with research staff and then again online by clicking on the assent/consent process. All participants also received a take-home participant information sheet that detailed the risks and benefits of the study and included contact information for study staff and the president of OMRSEM. Participation in this study was voluntary and anonymous.

Measures

Demographics/background information and other variables included gender and sexual orientation which used different questions including (Note: quoted text is translated from the Thai questionnaire): “Which of these words best describes you?” and “If you were to have a committed partner (fain), what gender would you like them to be? Choices included male, female, ladyboy/transgender women, gay men/MSM, tomboy, transgender men, lesbian and bisexual. There were also questions about age, educational institution, grade point average (GPA) and some sensitive behavioral questions like “Have you been a victim of violence based on pride, honor or age of the establishment? Choices included yes, both perpetrator and victim, or one or the other/never). “Did you use drugs (Crystal Meth, Ketamine, Ecstasy) before or during sexual activity.” Choices included often/sometimes or never, and “Do you need advice on sensitive matters such as issues regarding your lifestyle, emotions, feelings, etc.” Choices included yes I do, or no I don’t.

Polydrug use is measured by the use of at least three types of drugs [20]. These questions include “Have you used the following substances?” informed by our previous research and literature [21, 22], options included kratom cocktail/4×100, pro, B5, Xanax/Alprazolam, amphetamine, crystal methamphetamine, ecstasy/MDMA, ketamine, heroin injection, and crystal methamphetamine injection. Choices included Yes in the past month, Yes in the past three months, Yes in the past six months, Yes in the past year, and Yes over a year ago, or Never. If their answer is Yes in the past month, Yes in the past three months, or Yes in the past six months, they will be considered to have used that drug. [22].

Data analysis

The statistics used in this analysis included descriptive statistics, the χ2 tests, binary and multivariate logistic regression analyzes where polydrug use is the dependent variable and where education is the adjusted variable. Surrogacy, pride-based violence, drug use before or during sex, and need for counseling were independent variables. STATA 14.0 software (StataCorp, Texas, USA) was used for all statistical analyses.
