Decline to answer (DTA) options let respondents skip specific rows or columns in a table. Use dta row for column-specific opt-outs and dta col for row-specific opt-outs.
Tip! Whereas the traditional declinetoanswer tag provides an opt-out option for an entire table, the dta row and dta col tags provide opt-out options for individual columns and rows.
Details
- The
dta rowanddta coltags are intended for tables with text input (including integer, number, etc.). - The
dta rowtag creates a row of DTA options for table columns, and thedta coltag creates a column of DTA options for the rows. - To define DTA options, use the
dta rowordta coltag, and include an option number, followed by a period and the option text (e.g.,dta col: 99. Don't remember). - Use the
row idsandcol idselement decorators to assign DTA options to specific rows or columns. If not specified, the opt-out option applies to all rows or columns. - The
dta rowanddta coltags also support thedescdecorator to customize the opt-out description in the reports. - You can include multiple
dta rowordta coltags on a single table as long as different IDs are used. - Avoid using both
dta rowanddta colon the same table.
Tip! Do you need to create a DTA row or column for other table types?
- Radio tables: Add a labeled option (e.g., "99. None") as an opt-out.
-
Checkbox tables: Use an "exclusive" option with the
exclusivetag (or decorator) as an opt-out.
Additional examples
'dta col' tag with 'row ids' decorator
The row ids decorator can be used with the dta col tag to specify which rows should display the opt-out option. If a row is not listed, the space will be blank.
In the example below, we offer the opt-out option "Unfamiliar" for all rows except row 2, "Nike," assuming everyone is familiar with the brand.
'dta row' tag with 'col ids' decorator
The col ids decorator functions similarly to its peer row ids. It can be used with the dta row tag to specify which columns should display the opt-out option. See below.
Multiple DTAs
It may be necessary to offer different opt-out options in certain scenarios. Multiple dta row or dta col tags can be used together as long as they have unique IDs. Similar to the declinetoanswer tag, when including multiple dta row/dta col tags on a widget, the respondent can only select one of the options.
In T4 below, the dta row '98. Don't know' provides opt-out options for columns 1 and 3, while row '99. Cannot disclose' displays opt-out options for columns 2 and 3. The system class add_to_100_percent is included as a shortcut to define the sum-to-100% table features.
