![]() ![]() different unlinked age groups? By enabling the longitudinal data collection in your project setup and then designating your preferred survey instrument as the default survey for each group (or arm), you will be able to have a different public survey links for different types of groups of participants! Are you conducting a project that will need a different public survey for different types of participants, e.g.This will have the field to never show up on the first event but will have it show up on the subsequent events for this instrument. Are you using longitudinal data collections and would like to add a question to the instrument to be answered in a subsequent event instead of the first one? You can do this using the branching logic with smart variables such as. ![]() You can access this through the survey settings and find Survey-specific email invitation field. Did you know that you can set up REDCap to send surveys to specific emails? This allows you to send specific surveys to different email address instead of designating only one email field for the whole project.Note: If you need to find the variable name of your instrument, consult the codebook.Therefore, our smart variable should appear as “” In this case, we want to see how long it took for the “Demographics” survey to complete in seconds. Inside of the descriptive field label add the smart variable with the proper data.Add the action tag to this field so that it is not visible to participants taking the survey and only appears when checking the form itself in the Record Status Dashboard. Within the survey you can set up a descriptive field labeled “Survey Elapsed Time”.Example: Suppose you have an instrument “Demographics” and you want to find out how long it took for your users to complete this survey when looking at the records in the Record Status Dashboard.Do note that ‘M’ and ‘m’ are case sensitive for months and minutes respectively. The “units” portion can be set to one of the following: ‘y’ representing years, ‘M’ for months, ‘d’ for days, ‘h’ for hours, ‘m’ for minutes and ‘s’ for seconds.Smart Variable Spotlight – : Do you want to know how much time it took for a user to complete a survey? The smart variable allows you to see the amount of time that passed between the start of the survey being taken and when it was completed.If in this example the fictional Record #34 was part of the “chemistry_dept” DAG the smart variable would return “chemistry_dept” for the value! These include Economics (economics_dept), Chemistry (chemistry_dept) and Biology (biology_dept). Example: A REDCap project has a DAG of department names at Tufts University.Smart Variable Spotlight – : If your project uses DAG’s (Data Access Groups) you can use this smart variable to determine the DAG that the current record belongs to!.Attempting to apply both action tags will prevent any date restrictions from being applied to that field. These action tags are mutually exclusive.Any date value from the current date to any future date is acceptable. Prevents any past date values from being entered.Any date value from the current date to past dates is acceptable. This action tag prevents any future date values from being entered.This external module adds the following new action tags:.Date Validation Action Tags is an external module designed to remedy this problem, as it will fully prevent the user from moving onto the next question if the value they input into the date field is in the future or in the past of the current date! While these restrictions will indeed warn the user if their inputted date value is invalid, it will not fully stop them from entering the invalid date and progressing to the next question. External Module Spotlight – Date Validation Action Tags: Many projects have fields such as “Date of Birth” or “Date of Previous Visit” in which you may want to setup a strict minimum and or maximum value range to ensure users cannot input dates in the past or future.To get the most out of REDCap, please refer to these helpful hints: August 2022 ![]()
