title: Tracking procedures for locating high-risk youth.
abstract: Few published works are available that provide a comprehensive description of tracking procedures. This article describes the data collection tracking protocol that was used in Project Towards No Drug Abuse (Project TND), to follow high-risk youth over a 5 1/2 year period. Youth were followed from 1994 through 2000. A total of 35% of these youth were assessed 5 1/2 years later. Collapsing across the last two waves, 46% of these youth were followed an average of 5 years later. These procedures may be helpful in tracking highly mobile youth.
