DFengage Version 2.0.0/2.0.1
Overview
DFengage Version 2.0.1 – patch release – 2024/03/21
- The “Clear this value” option is now available for date and time fields as well as VAS fields. “Clear this value” only appears when a field is optional and does not appear when a field is required or essential.
- A bug was fixed where the app skipped hidden fields in an activity even when the user’s role permission allowed hidden fields.
- A bug was fixed on date fields where an error message such as “Please enter your response in format DD/MMM/YYYY” could appear incorrectly for valid dates. This fix also corrected an issue where including Jan 30 or 31 in a date field’s legal range (e.g., 2024/01/31-today) would prevent the study from opening in DFengage.
- The History page has been updated to always sort completed activities with most recent activities listed first.
- A bug was fixed on iOS where opening the app from a notification card could take you to the login page instead of the PIN page, although you were already logged in.
- A bug was fixed where local data was not removed when the app was deleted and reinstalled if the local data had previously been backed up.
- Minor interface fixes were applied.
- The DFengage User Guide has been updated with improved navigation on mobile devices.
DFengage Version 2.0.0 – release date: 2023/12/15
DFengage is a mobile application for the collection of electronic patient-reported outcomes (ePRO) that allows research participants to complete study activities (such as questionnaires, surveys, and diaries) assigned by the research team.Key updates to DFengage in this release include:
- Overall redesign: DFengage has been redeveloped from the ground up, creating a foundation for new capabilities in future releases. The look and feel of the app has been updated, including a new app icon. The “task” and “questionnaire” terminology used previously has been updated to use “activity” consistently throughout. App navigation now includes three pages: Today, History, and Settings.
- Updated Today page: New section dividers have been added for overdue, due now, upcoming, and completed activities, providing a more comprehensive view of the participant’s activities for today.
- Custom activity help: Plate and field help defined in DFsetup are now displayed in DFengage to provide more guidance for the participant.
- Validation checks: A warning message is now displayed for values outside the defined legal range. The participant can continue to the next question even if the value is illegal. Data formats are now shown in the input field, with a warning displayed for responses that do not match the format.
- Mid-activity interruptions: Participants can now exit an activity without losing their responses so far and continue the activity later.
- Enhanced form design options: Activities may now include field instructions and grouped fields of any data type. Basic HTML formatting is supported in the field prompt, instructions, and help.
DFengage is available for iOS and Android. The most up-to-date version is always available through the respective online store.

Client-side

- in Schedule View, when using the Save As Excel action, ensure that the fill color for ongoing, scheduled subjects is applied correctly.

- When listing field or page history, permissions are enforced by the DF_SBhsitory report, not DF_ATmods as shown.
- When using the Metadata panel and adding a second query to the same data field, prevent this second query from being dropped during a Refresh action.

- A bug in DFsetup’s visitmap dialog that could allow the user to save invalid visit range information has been fixed.
- A bug that could lead DFsetup to exit unexpectedly due to an uncaught auto-save timer event has been fixed.
- The following updates have been applied to DFexplore:
- While loading study info from the server, ignore clicks on the button. Also ignore force quit action on macOS (Cmd+Q).
- Enable resizing of the Image Router subwindow and remember the size set by the user.

- Two improvements have been made in the implementation of subject schedule:
- For an in-study cycle with both baseline and pre-baseline visits, if the baseline visit has occurred but the pre-baseline visit has not, the pre-baseline visit must be identified as overdue.
- If end-study cycle visits are set to be required by the conditional visit map and they are now overdue, they must be identified as overdue.

DFengage Version 2.0.0/2.0.1
Overview
DFengage Version 2.0.1 – patch release – 2024/03/21
- The “Clear this value” option is now available for date and time fields as well as VAS fields. “Clear this value” only appears when a field is optional and does not appear when a field is required or essential.
- A bug was fixed where the app skipped hidden fields in an activity even when the user’s role permission allowed hidden fields.
- A bug was fixed on date fields where an error message such as “Please enter your response in format DD/MMM/YYYY” could appear incorrectly for valid dates. This fix also corrected an issue where including Jan 30 or 31 in a date field’s legal range (e.g., 2024/01/31-today) would prevent the study from opening in DFengage.
- The History page has been updated to always sort completed activities with most recent activities listed first.
- A bug was fixed on iOS where opening the app from a notification card could take you to the login page instead of the PIN page, although you were already logged in.
- A bug was fixed where local data was not removed when the app was deleted and reinstalled if the local data had previously been backed up.
- Minor interface fixes were applied.
- The DFengage User Guide has been updated with improved navigation on mobile devices.
DFengage Version 2.0.0 – release date: 2023/12/15
DFengage is a mobile application for the collection of electronic patient-reported outcomes (ePRO) that allows research participants to complete study activities (such as questionnaires, surveys, and diaries) assigned by the research team.Key updates to DFengage in this release include:
- Overall redesign: DFengage has been redeveloped from the ground up, creating a foundation for new capabilities in future releases. The look and feel of the app has been updated, including a new app icon. The “task” and “questionnaire” terminology used previously has been updated to use “activity” consistently throughout. App navigation now includes three pages: Today, History, and Settings.
- Updated Today page: New section dividers have been added for overdue, due now, upcoming, and completed activities, providing a more comprehensive view of the participant’s activities for today.
- Custom activity help: Plate and field help defined in DFsetup are now displayed in DFengage to provide more guidance for the participant.
- Validation checks: A warning message is now displayed for values outside the defined legal range. The participant can continue to the next question even if the value is illegal. Data formats are now shown in the input field, with a warning displayed for responses that do not match the format.
- Mid-activity interruptions: Participants can now exit an activity without losing their responses so far and continue the activity later.
- Enhanced form design options: Activities may now include field instructions and grouped fields of any data type. Basic HTML formatting is supported in the field prompt, instructions, and help.
DFengage is available for iOS and Android. The most up-to-date version is always available through the respective online store.

Client-side
- File download hyperlinks, embedded in the custom HTML content provided by your DFdiscover server, now work correctly in the login dialog of desktop applications.

- This change improves the performance of DFcollect in low bandwidth and/or high latency environments (update available via Google Play and App Store).
- The following updates have been applied to DFexplore:
- in Schedule View, when using the Save As Excel action, ensure that the fill color for ongoing, scheduled subjects is applied correctly.
- When choosing Save As PDF and the blank CRF book option, respect the Subject Alias preference, pre-printing either the numeric Subject ID or the Subject Alias, or a new option to not print any Subject identifier at all.
- When listing field or page history, permissions are enforced by the DF_SBhsitory report, not DF_ATmods as shown.
- When using the Metadata panel and adding a second query to the same data field, prevent this second query from being dropped during a Refresh action.
- In List View, all matching data is now output when the Subject filter is used in combination with cross-plate criteria.
