The PGNU will continue to work on psychometric data linking of substance use measures and key indicators of HIV prevention and treatment. PGNU will analyze the results of the item response theory (IRT) and/or agreement analysis of multiple substance use measures, produce at least one manuscript on these results, and present the findings at conferences and/or meetings, as needed. PGNU will also support the efforts and decisions of the C3PNO in the implementation of data linking approaches based on these findings by participating in conference calls and meetings as needed to share their expertise.
