What is YMAP?


The Young Men’s Affiliation Project, or YMAP for short, is a study of the social networks and venue affiliations of young gay and bisexual men in Houston. We are interested in learning more about how the people, places, and spaces important to young men who have sex with men impact their sexual health. The study is structured in two phases: Phase I looks at networks among the venues that serve this population, and Phase II examines the behaviors and networks at the individual level. We use these networks to understand how things like knowledge, behavior, and disease spread through our community and identify the best places to intervene. If you are a 17-29 year old guy who is interested in cash, free testing or helping make our community a healthier place - contact us and join YMAP!

How does it work?

The Young Men's Affiliation Project uses a social network analysis to map the people, places and spaces that are important to the sexual health of our community. This project uses two phases to analyze the connections and relationships that exist in our community. 

Phase I:

This phase focuses on the places that MSM (men who have sex with men) frequent and how these venues interact with one another. In the process, we identify venues that are heavily trafficked by the LGBT community and interview representatives from each of these venues. During these interviews we record data focused on its relationship with other venues and the LGBT community. 

This data is then analyzed and applied to the social network analysis.

Phase 2: 

This phase focuses on the individual. Using an interview process, we collect data about each guy we bring in to the study including what venues they go to and who they interact with. This data is then analyzed and used in the overall social network analysis. This phase helps us understand the fundamental way HIV spreads and interacts with the environment as a function of the Respondent Driven System (RDS)  used to recruit participants, 

Respondent Driven System?

RDS is a recruitment system that focuses on two types of participants: seeds and sprouts. A limited number of seeds are selected using a substantial screening process, and after their interview they are tasked with recruiting 4 more participants, or sprouts. These sprouts are then interviewed and also asked to bring in 4 more sprouts; this drives the study forward. The goal is to reach 500 participants using this system. The advantage of RDS lies in it's scientific relevance to a study focused on determining how a disease spreads. This forces the statistical sample to be a network of people that are connected in some way, representing this spread more tangibly. 

Social Network Analysis? 

The data of this study is inputted in to a social network analysis, as previously mentioned. This uses statistical concepts to establish relationships between individuals, venues and HIV. Using various pieces of data we are able to make graphics that capture multiple variables on a canvas of these relationships. Here is an example of the results of a social network analysis done in the past:

 Social Network Analysis

As you can see, these networks are hyper informative and comprehensive. 

All these tools are used to know the most tiny details of the HIV networks present in these cities.
