National Longitudinal Study of Neurodevelopmental Consequences of Substance Use - Meeting Agenda

National Longitudinal Study of Neurodevelopmental Consequences of Substance Use

May 27-28, 2014
6001 Executive Blvd, Conf Room D (main floor)
Bethesda, MD 20892

Meeting goal: to develop recommendations on best large-scale design and measures to assess developmental effects of substance exposure (including, nicotine, alcohol, marijuana and other drugs; and beginning prior to exposure) during childhood through young adulthood.

Structure: 90-minute topic blocks, including one short presentation (~10 min) to outline the main issues to be resolved, followed by open discussion among panel members, and 10 min general discussion (for NIH staff or members of the public).

Themes for multiple sessions:  Data harmonization; data sharing; ethical issues/confidentiality; design preferences, issues, and alternatives
