National HIV Behavioral Surveillance (NHBS) - Seattle

National HIV Behavioral Surveillance (NHBS) - Seattle

Seattle is one of 23 large metropolitan areas participating in a national health survey funded by the Centers for Disease Control & Prevention.

Each year we survey different populations to learn about HIV prevalence, sex and drug use, HIV testing, and use of local HIV prevention programs. The survey provides up-to-date information to help improve HIV prevention in King County. Seattle has been an important and successful part of this effort since 2004.

How to get involved

The Seattle NHBS team conducts in-person interviews, starting in June 2023 through March 2024.


Project First

Project First recruitment is conducted using a coupon system from July 2023-March 2024. People interested in participating in a survey will need to have a coupon in order to contribute to the information collected. Some people who complete the survey may be asked to refer other people they know – again through coupons.

For Project FIRST, people must have a coupon in order to participate, but having a coupon does not guarantee participation.

If you receive a coupon, please call to schedule an appointment.


PITCH Study will return as a venue-based-recruitment for data collection in 2023. We will be in the PITCH Study Van throughout Seattle and Snohomish County from June-November 2023 at various events.

Potential participants will be approached by someone from the outreach team during an event. A few questions are asked of respondents to see if they are selected for the survey. Those who are selected by the computer and agree to participate are eligible to be financially compensated for their time as a token of appreciation.

Members of the community are not able to volunteer for either survey.

All information collected is confidential and anonymous.

Surveys are conducted in a private location to ensure the confidentiality of all participants.
