***** To join INSNA, visit http://www.insna.org ***** Dear SocNet members -

I'm happy to announce that the National Longitudinal Survey of Adolescent Health (Add Health) now has a version of the school friendship network data that might be of interest to many of you.   These files are designed to make use/analysis of the network data simpler and streamline the data process for those who are only interested in network structure and not adolescent health or behavioral outcomes.  The formal announcement is below. 

Add Health collected (nearly) complete friendship network data on about 76000 adolescents in schools across the country.  Theses files contain just the bare network information: the arc/edge lists and limited node attribute data.  These data thus provide multiple replications of the same instrument in many different school contexts. Feel free to email me directly if you have any questions.

All the best,
Jim

****  DATA RELEASE ANNOUNCEMENT  *****

Network Structure Files

Data files created from the Add Health complete in-school friendship networks are now available to researchers.  For each school pair, the files contain a valued friendship network and information on sex, grade in school, race, school pair, and total number of nominations made, including those to non-matchable or out-of-school friends.  Two sets of files are available, one for researchers interested in the structural properties of adolescent friendship networks but who are not interested in other outcomes measured by Add Health and one for researchers wanting to link these data to outcome variables collected by Add Health.  The files are stored as arc/edge lists in the PAJEK .PAJ format.  Information on this freely available network software can be found at: http://vlado.fmf.uni-lj.si/pub/networks/pajek/ .  More information on the network structure files can be found in the on-line codebook, structur.zip, at http://www.cpc.unc.edu/projects/addhealth/codebooks/wave1. Researchers who would like copies of the data should contact [log in to unmask]
