Completing the DSUR

What is the DSUR survey?

It is a series of questionnaires put together by UC Davis social science researchers. The survey is different each quarter, and researchers use the survey to help select qualified participants for their studies.

When should I complete the DSUR?

It should be taken early  in the quarter before you take other online surveys. It is an online study and counts toward your online study limit.

But I did another online study first and used up too many of my online study credits, and now I cannot take the DSUR. Isn’t there anything you can do?

No. The limit for online studies is firm. You can take 75% of your credits each quarter in online studies. If you do not know how many credits that is, multiply the number or credits you can earn this quarter by .75. You cannot go over this number, and it may mean you cannot take the prescreen. If you want to understand why there is a limit on online studies, please read that section of the FAQ.

Why should I complete the DSUR?

The DSUR is an easy first credit. It is also a prerequisite for many of the other experiments posted on SONA.

Do I have to take the DSUR?

No, participation is voluntary.

How long does it take to complete the DSUR?

Time to complete the DSUR varies across students, but it is supposed to take you approximately 1 hour.

I completed the DSUR in a previous quarter, can I take it again?

Yes. The DSUR changes from quarter to quarter, so students are allowed to retake it. In fact, researchers need students to retake the DSUR every quarter.

When will I receive credit for the DSUR?

You will receive 1 credit for completing the prescreening, which will happen automatically once you complete the it. If you do not received credit for the prescreening after completing it, contact the Subject Pool Coordinator at
