    • edit the Recruitment text (this text will be shown to recruiters and will be used by them to recruit subjects for your study),

    • decide whether you wish to set up the Advanced filtering (this allows you to create multiple filtergroups that are not linked to each other),

    • set the function Exclusive subjects (If you select this feature, potential subjects for your study cannot be recruited for other studies. Please note that this may prevent other researchers from finding enough participants.) and

    • decide whether Complete filter matches only will be shown to the recruiters of your study or if there will be some subjects displayed, in which certain characteristics still have to be queried

  4. By clicking on Filter you are able to set filter criteria

    • select whether you want to create a filter regarding the First language, Highest educational degree, Handedness, Has hearing aid?, Age or Sex

    • click on Save

    When you click on Add new in Filters, you are able to set another filter group with specific filters

    Note

    This is necessary, for example, if you need subjects both at the age between 20-30 and 50-60.

  5. In Excluded studies you can select certain studies in which your subjects must not have participated

  6. When you click on Inclusion/exclusion criteria, you can add Additional subject characteristics that should be verified during the recruitment

  7. If recruitment is to take place by e-mail, proceed as follows:

    • click on Mail Settings

    • define an E-mail subject

    • add an E-mail body

    Note

    It is not intended to send attachments in the first e-mail via Castellum. Instead, links can be inserted.

Start and stop a study

After a study has been created it is still in a draft state. Only Study Approvers have the permission to start recruitment. Depending on your organization, there may be different organziational steps such as a review associated with that.

In order to start or stop a study, a Study Approver needs to follow these steps:

  1. Go to Studies on the front page, click Details next to the study you wish to start/stop.

  2. You can find the button Start in the left upper corner under the study name. By clicking on Start you initiate the recruiting process

Finish a study

  1. Go to Studies on the front page, click Details next to the study you wish to start/stop.

  2. You can find the button Finish study in the left upper corner under the study name.

Note

All information related to potential subjects that were not invited to the study will be deleted when the study is finished. If you finish and then resume a study, it is possible that subjects that were already found to be unsuitable are proposed again.

Delete a study

When a study should be deleted depends on the rules of your specific organization. We assume that it makes sense to delete all study data after few years, effecitvely anonymizing the research data.

Once you delete a study from Castellum it is no longer possible to answer to export or delete requests from subjects. Make sure that all relevant external has been deleted before you delete a study from Castellum. Then proceed as follows:

  1. Go to Studies on the front page

  2. Choose the study you want to delete by clicking on Details next to it

  3. Make sure the study is finished (see Finish a study)

  4. Click on Delete under the study name

    • Confirm the notice I have made sure that all external data related to this study has been destroyed

    • Click on Confirm
