Thank you for your interest in participating in this study.

The Anxiety Studies Division is directed by Dr. Christine Purdon and Dr. David Moscovitch, who are both faculty members in the Department of Psychology at the University of Waterloo. The Anxiety Studies Participant Pool is a pool of valued volunteers from the community with and without anxiety problems, who are willing to be contacted about participation in research on anxiety and mood issues.

In order to determine your eligibility for the Pool, we need to ask you questions about symptoms you have or may have had in the past, including but not limited to symptoms of depression, anxiety, the use of alcohol and other substances, etc. As described in detail on the next page, your responses will always remain completely confidential, will be stored on a secure, encrypted server, and will only be used to determine your eligibility for participating in our research studies.

There are two parts to the initial screening process. The first part consists of a brief, online, confidential questionnaire that will take you just a few minutes to complete. The second part involves more detailed questions regarding your anxiety (or lack thereof), which will take place in person at our facilities on the University of Waterloo campus. You cannot complete the second part unless you first complete the brief, online, confidential questionnaire. There is no compensation for completing this first brief questionnaire. More information about the second part of the process and compensation for completing that part will be provided once you have completed the initial questionnaire. If you are interested in completing the online questionnaire, please read on.

This question is for testing whether or not you are a human visitor and to prevent automated spam submissions.
