Willing to Help?


The IPIP collaboratory was funded from 1992 to 2006 by the U.S. National Institute of Mental Health, but that support has now ended. To keep the collaboratory open for business, we are now asking for contributions.


If you find this web-site useful and want to keep it available for future use, please make a contribution using PayPal (click below).


If you would prefer to contribute by check, please make it payable to “IPIP Project: ORI Community and Evaluation Services,” and send it to: ORI Community and Evaluation Services, 1776 Millrace Drive, Eugene, OR 97403-2536, USA.
(ORI Community and Evaluation Services is a non-profit 501(c)(3) public charity, so in the United States IPIP-related contributions can be used as tax deductions.)

To personality researchers around the world, we thank you!
