This is an old revision of the document!

Please go to our REDCap webpage (https://redcap.ru.is) and log in with the credentials you have received.

Figure 1: The log in page of redcap.ru.is.

When logged in you are presented with the homepage. Please navigate to My Projects marked with green.

In My Projects you will see all of the projects that are to be used. The projects contain one questionnaire or a collage of questionnaires. The questionnaires in each project should be in two languages – English and the native language at each ESADA center. The questionnaires are setup so that in the beginning the participant can choose the language of the questionnaires. The participant will receive the questions in a language depending on the language they choose.

For each ESADA center there will be two projects - they include the same questionnaires (ISI, FSS, ESS and PSQI) along with the Patient Global Impression scales (PGI). The difference between the two projects is the that one project is for use at baseline and the other for use at follow-up. The baseline project includes the PGI Severity scale and the follow-up includes the PGI Improvement scale.

Please start by selecting the appropriate project from the list in My Projects.

SENDING OUT QUESTIONNAIRES

All of the questionnaires will be sent via private link to the participant. On the left panel under Data Collection there is a tool called Survey Distribution Tools. The following image shows the Survey Distribution Tools page. Under that you will find the public link to the questionnaire. However, when sending questionnaires not used for recruitment, it is preferable for the responses not to include personally identifiable information. Therefore, each participant receives the questionnaires on a private link only connected to their research ID. To do that the participants need to be added to the Participant List, where their e-mails are linked with the research ID. NOTE: the public survey link is useful to test if the questionnaire is working properly.

Figure 3: The **Survey Distribution Tools** are located in the menu on the left under **Data Collection**.

To add participants to the participant list please navigate to the Survey Distribution Tools in the menu on the left. On the Survey Distribution Tools page, please choose Participant list.

Figure 4 shows the Participant List page.

Figure 4: The **Data Distribution Tools** are located in the menu on the left.

Before adding participants, the Participant Identifier (research ID) option needs to be enabled. Thereafter, you click on the Add Participants and the following page appears.

Figure 5: The window where one or more participants can be added to the participant list. It is important to link the correct e-mail address to the correct research ID.

Participants are added to the list as seen on the figure above. First the e-mail of the participant is entered followed by a comma and then the research ID (ESR number). Multiple participants can be added to the list simultaneously by inputting the e-mail and research ID of multiple participants, take care to only input one participant per line.

The private links can then be sent to the whole participant list at once by clicking Compose Survey Invitations on the Participant list page.

Figure 6: To send out the private survey links you go to **Compose Survey Invitations**.

You can send invitations to answer the questionnaire to the whole group or a subset of the group by checking the boxes by the participants on the right on the Compose Survey Invitations page.

Figure 7: This window is where the invitations are composed and scheduled. The invitations can be sent out in bulk to the whole participant list at the same time.

The invitations can be sent immediately or at a specified time. Further, reminders can be sent up to 5 times after the initial invitation is sent (take care to not overload the participant's inbox and keep the reminders limited). NOTE: remember to select the correct e-mail address you want to send the invitations out from - it should be the sleeprevolution e-mail provided by us.

On the left panel under Data Collection is the Record Status Dashboard. There the questionnaire responses from participants can be monitored. The Survey Invitation Log under Survey Distribution Tools is also another tool to monitor invitation responses, for example if there are scheduled invitations and reminders. The following figure shows the Record Status Dashboard and how the incomplete answers can be monitored and followed up if needed.

Figure 8: The **Record Status Dashboard** shows the questionnaire responses from participants. The orange marks a record where the participant did not finish the questionniare.

To follow-up with the participant and ask them to finish answering - note down the Record ID and where the participant stopped answering and go back to the Participant List. From there you can choose the questionnaire that is missing from the drop-down list at the top (see Figure 9) and send a link to the participant by using Compose Survey Invitations.

Figure 9: Marked in **green** is where the drop-down list is located to choose the list that is missing.

To ensure that the protocol is followed in all ESADA centers across Europe, the ESADA Study Protocol project has been made in REDCap for each center. The project includes all steps and phases of the ESADA study protocol. It is designed as a checklist and also a way for you to record the body and vital signs measurements. Furhter, you can keep record of the diganoses and treatments the participant receives.

When a participant is starting the study, the Study Protocol project is opened in REDCap and a new record is added to the project. That is done by selecting Add/Edit Records under Data Collection in the menu panel. Figure

Figure 10: Marked in **green** is where the **Add/Edit Records** is located on the menu panel.

The data can be exported as a .csv file in Data Export, Reports and Stats under Applications in the panel on the left. The following image shows the data export page and where to initiate the export.
