简要总结
This study evaluates the pre-implementation phase of a host-led harm reduction model for men who have sex with men (MSM) engaging in chemsex in Bangkok, Thailand, focusing on understanding harms, contexts, and needs to develop a tailored intervention.
详细描述
HAMMOCK is a cross-sectional mixed-methods study designed to explore chemsex practices among MSM, including both hosts and guests, as well as key stakeholders such as CSOs, hospital staff, and police.
The study aims to:
- Explore substance-related, sexual health, mental health, and socio-legal harms
- Understand the context and dynamics of private chemsex parties
- Co-develop a novel host-led harm reduction model
- Identify barriers and facilitators to implementation The study includes both quantitative (self-administered questionnaires) and qualitative (in-depth interviews) components and follows a two-phase approach: exploration and preparation phases under the EPIS framework.

结局指标
主要结局
Substance use-related harm assessed by self-administered questionnaire
时间窗: Baseline (during Exploration phase, prior to model development)
Substance-related harms will be assessed using a structured self-administered questionnaire. The assessment includes: * Patterns of substance use (snorting, injecting, ingesting, anal insertion) * Frequency of use * Physical harms (e.g., injection-related injuries, overdose) * Psychological harms (e.g., substance dependence) This is a descriptive assessment; no composite scale score is generated.
Sexual health risk behaviors assessed by self-administered questionnaire
时间窗: Baseline (during Exploration phase, prior to model development)
Sexual health risks will be assessed using a structured questionnaire including: * Number of sexual partners * Condom use * HIV/STI testing history * Self-reported HIV status * Pre-exposure prophylaxis (PrEP) use and adherence * Antiretroviral therapy (ART) adherence among participants living with HIV This is a descriptive assessment; no composite scale score is generated.
Depression severity assessed by Patient Health Questionnaire-9 (PHQ-9)
时间窗: Baseline (during Exploration phase, prior to model development)
Depression will be assessed using the Patient Health Questionnaire-9 (PHQ-9): * Score range: 0 to 27 * Interpretation: * 0-4: Minimal depression * 5-9: Mild * 10-14: Moderate * 15-19: Moderately severe * 20-27: Severe Higher scores indicate worse depression severity
Anxiety severity assessed by Generalized Anxiety Disorder-7 (GAD-7)
时间窗: Baseline (during Exploration phase, prior to model development)
Anxiety will be measured using the Generalized Anxiety Disorder-7 (GAD-7): * Score range: 0 to 21 * Interpretation: * 0-4: Minimal * 5-9: Mild * 10-14: Moderate * 15-21: Severe Higher scores indicate worse anxiety
次要结局
