Standard prices are available for commercial users for the JDI and related measures. Discounts off standard prices may be available for commercial researchers who return their data to the JDI Research Group. Specifically, if you are using the JDI strictly for academic research, the JDI Research Group is willing to waive the cost of the JDI in return for item-level data collected as part of your research. This allows us to continually learn about and update the JDI and related scales. See our non-commercial contract agreement and our commercial contract agreement for more details. Fill out the form and mail or fax the information back to the JDI Office. Substantial discounts off standard prices can also be made available for companies willing to share data to the JDI research group (confidentiality is guaranteed). To discuss JDI research partnerships, please send email to Dr. William Balzer (wbalzer@bgnet.bgsu.edu) or Dr. Jennifer Gillespie (jcarr@bgnet.bgsu.edu).
