on a per-study basis. The fixed time setting always indicates the day the study is to occur. before Time Threshold Includes Yes or No value to indicate if the system should factor Weekends in weekends when enforcing the sign-up and cancellation time limits. If set to Yes, then a deadline that would ordinarily occur on a weekend is pushed back to the Friday before the weekend. The system will push back the deadline in full days, so a rolling time window threshold that would occur at 2:30pm on Sunday would be moved to 2:30pm on Friday. If set to No, the deadline may occur on a weekend. Random Study Order Yes or No value to indicate if the system should list studies (to participants) in random or alphabetical (by study name) order. All non-participants will always see studies listed in alphabetical order. If random order is chosen, the list of studies is randomly listed every time a participant views the list of available studies. Credit Display Yes or No value to indicate if the credit value for studies should be listed on the study listing page, for participants. The credit value will always be visible once a participant clicks on a study to learn more about it. The reason to disable the credit display from the main study listing page is if there is a concern that participants are more or less likely to view studies that have a higher credit value. If set to Yes, the credit value will be displayed on the study listing page. Available Study Display Yes or No value to indicate if all (active, approved) studies should be displayed to participants when they go to view the list of studies. If set to No, then only those studies with available timeslots will be listed. It may be useful to set this to Yes if there are frequent changes in timeslot availability and you want to make a participant aware of studies even if there are no timeslots available at the moment. Online Display Yes or No value to indicate if on the list of studies displayed to participants, participants can see immediately if the study is an online study. If this is set to No, there will be no indication on the page listing all the studies to participants that the study is an online study. This may help to reduce selection bias. Regardless of this setting, once the participant clicks on a specific study, they will see at that point if it is an
