The Participant Agreement for Contact Tracing (PACT) Study: Enhancing Partner Notification Services.

Patients diagnosed with chlamydial infections (a sexually transmitted disease) are asked to notify their sex partners and tell them to seek medical evaluation. This project tests an enhancement to the materials provided to patients to help convince their partners to seek evaluation against the standard of care, which is a brief notification instruction. The desired outcomes are greater levels of notification by participants of their partners and lower levels of reinfection among participants.
