Prospective cohort follow-up
LONGSCAN is a consortium of research studies operating under common by-laws and procedures. It was initiated in 1990 with grants from the National Center on Child Abuse and Neglect through a coordinating center at the University of North Carolina Injury Prevention Research Center and five satellite sites. Each site is conducting a separate and unique research project on the etiology and impact of child maltreatment. While each project can stand alone on its own merits, through the use of common assessment measures, similar data collection methods and schedules, and pooled analyses, LONGSCAN is a collaborative effort.
