How will follow-up tracking be conducted to ensure confidentiality?
The 3- and 12-month follow-up interviews will require that study staff track and locate participants. UCLA ISAP has developed procedures that result in high percentages of participants being located, as described in the Staying in Touch manual available at: http://www.uclaisap.org/trackingmanual/index.html. Tracking information will be gathered voluntarily from the participants during the initial interview. TSI study staff and county/treatment staff will ask participants to provide full names and aliases; date of birth; place of birth; residence address and phone; best mailing address and phone number; work address and phone number; name, address, and phone numbers of all immediate family and friends, case worker, clinic, doctor, or other regular contact/agency. This information will be the primary source of the tracking and locating conducted. Follow-up interview tracking will begin with a letter mailed to the last known address, requesting that the person contact study staff regardin
