Hoofd instellingen
Verplicht (mandatory)
Beschrijving
Met deze optie kan de enquête-beheerder instellen dat een bepaalde vraag beantwoordt moet worden voordat de deelnemer verder kan gaan met invullen. Als je een vraag hebt met subvragen en je wilt niet alle onderdelen verplicht maken, gebruik dan de optie Minimum aantal antwoorden (min_answers) op de tab Logica.
Beschikbare opties
- Aan - Vraag moet worden beantwoord voordat de deelnemer naar de volgende pagina kan - de antwoordoptie 'Geen antwoord' wordt nooit getoond.
- Zacht - Als de vraag niet wordt beantwoord, wordt een waarschuwing weergegeven wanneer wordt geprobeerd door te gaan naar de volgende pagina - de deelnemer kan er echter voor kiezen de waarschuwing te negeren en verder te gaan. Merk op dat de optie 'Geen antwoord' nog steeds wordt weergegeven (indien geactiveerd in de instellingen voor enquêtepresentatie)
- Uit (standaard) - Vraag kan onbeantwoord blijven
Optie 'Anders' (other)
Beschrijving
Deze optie wordt bij meerdere vraagtypes gebruikt. Je kunt hiermee een keuze toevoegen voor de gebruiker als die een ander antwoord wil kiezen dan de vooraf bedachte antwoorden. Normaal gesproken is dit een keuze 'Anders', waarbij dan eventueel kan worden aangegeven of die keuze dan door de gebruiker mag worden ingevuld.
Beschikbare opties
- Aan
- Uit (standaard)
These Core Settings are available in Version 1.92 and beyond
Condition (previously "Relevance equation")
Description
If the result value of the condition is "1" or "true", the question is "relevant" in the survey context, i.e. it is shown to the survey participant. If not, the question is hidden. Any survey question allows you to specify a relevance equation. This function is the successor of conditions and supports much more complex conditional logic.
Syntax Highlighting
Whenever you save the condition, it is evaluated and syntax-highlighted. Any errors will be color coded so that you can quickly detect and fix them.
Valid values
- Any condition that makes use of the ExpressionScript syntax, without surrounding curly braces.
Examples
Here are good examples of syntax highlighting.
Advanced settings
Hide tip (hide_tip)
Description
Most questions will usually include a tip that says "Please choose one of the following options" or a hint text on how to fill out the question. This attribute allows you to turn off or on this tips/hints.
These tips/hints include validation criteria messages (such as min/max number of answers, min/max/equals sum value). If hide_tip is enabled, these messages will be hidden. However, if the user enters invalid data, the tips will appear. They will be coloured in red, getting changed to green once the validation criteria are met.
Available options
- On - the tips/hints are hidden;
- Off (default).
Sort answers alphabetically (alphasort)
Description
If you use a list of radiobuttons or a dropdown list, you can order this list alphabetically by activating this option.
Available options
- On
- Off (default)
Label for 'Other:' option (other_replace_text)
Description
Short text string to replace the text "Other" as label for the "other" option.
Example
Entering a value of "Alternative:" for this attribute would result in the word "Alternative:" being used instead of "Other".
Display columns (display_columns)
Description
This setting allows you to display the answer options in more than one column. Add this attribute and a value indicating the number of columns you wish the question to use. It is recommended to limit the number of columns to the number of answers.
Valid values
- Any positive integer value greater than 0
Examples
- If you have 3 answers options and you want to show these horizontally, set this option to "3" instead of vertically.
- If you have 6 answers options and you want to show these in two columns (3 per column), then set this option to '2'.
Random answer order (random_order)
Description
This attribute causes LimeSurvey to ignore the existing order of answer options/subquestions, and instead it orders them randomly. This option permits the survey creator to diminish the survey bias. Please note that if a question has subquestions, the order of subquestions will be randomized, not the order of the answer options.
Available options
- Yes - Randomize when participant enters survey
- No (default)
Randomization group name (random_group)
Description
It places the questions into a specified randomization group, all questions included in the specified group being displayed in a random order to the survey respondents.
You can find a sample survey using randomization group name in ExpressionScript sample survey.
Valid values
Just enter any string you like (for example: 'group1'). All question which have set the same string within the randomization group name box will have their place in the survey randomized (=randomly exchanged among each other).
Preview
To preview the questions use the preview survey instead of the preview question group function, as the second has been reported to not show the questions in a randomized order.
Description
If enabled, the question will always be hidden - it will not be displayed to the survey participants. This function can be used in the following scenarios:
- If you wish to prefill a question with a URL and you want not to have it displayed on the screen. This overrides any conditions used within the survey because the respective question will not even be embedded on the page.
- If you wish to store or calculate a value on the fly via the ExpressionScript - Presentation.
Available options
- On
- Off (default)
'Other:' comment mandatory (other_comment_mandatory)
Description
It only applies to mandatory questions having an "other answer" option in which the participant can give a free text response ("other comment").
When this setting is activated and the participant selects the other answer (the "other checkbox" or "other answer in a list"), then he will have to give a comment in the "Other comment" input box in order to proceed to the next page.
Note that this option is not available for Multiple Choice questions because the "Other" checkbox status is not recorded in the database for this question type, only the content being recorded. This means that checking the "other" checkbox is just a visual effect that is only meaningful if the text box is filled in: that is why other_comment_mandatory is assumed to be set for this question type.
Available options
- On
- Off (default)
Example
If activated for a "Multiple options with comments" question and the user enters a value in the left part of the Other answer but doesn't enter text in the Other Comment part, a warning message will be displayed when he tries to proceed to the next page.
Array exclusion filter (array_filter_exclude)
Description
The Array filter exclusion setting allows you to use any multiple choice question to select or set which responses are NOT displayed in a subsequent list, array or multiple choice question.
- Multiple choice
- Multiple choice with comments
- Multiple short text
- Multiple numeric
- Array (5 point, 10 point, Yes/No/Unknown, Increase/Same/Decrease, By column)
- Array (Dual Scale, Text, Numbers)
- Ranking
Furthermore, each of these types of questions can filtered.
The only exception is Array by column which can filter other questions, but it cannot be filtered.How to set it up
Enter the question code of a multiple options question in the array exclusion filter box of the question you are currently editing. The respective question will be used as the source of information for the current question, the non-selected answers from the previous question being retrieved and used as answer options for the current question. For example, if your source multiple option question code is "Q1", enter "Q1" into the 'Array exclusion filter' box to start the filtering process of the answers. Only the answer options that are NOT selected in question Q1 will be visible in your question.
Cascading
The selected options can be displayed in cascade. This means that you can select a question which filters another question, which filters another question, and so on.
Example
Let's see together the below example:
In the screenshot from above, we got two questions. The first one is a multiple choice question type, while the second one is a multiple choice with comments question type. The answers you provide in the first question will be excluded from the second one. For example, if you select the ComfortUpdate option (that has the subquestion code 'SQ1') and the Plugin option ('SQ4'), the 'SQ1' and the 'SQ4' subquestion correspondents from the second question will be excluded. In our screenshot, we can observe that only the unselected options in the first question and displayed in the second one.
This example can be downloaded from the following link: Limesurvey_group_array_filter_exclude.zip. Import this question group into your LimeSurvey installation.
Numbers only for 'Other' (other_numbers_only)
Description
If this attribute is enabled together with the "option other" one (located under the General options tab), only numbers can be typed in by the survey respondents in the "other" textbox.
Available options:
- On
- Off (default)
Array filter (array_filter)
Description
The Array filter setting allows you to use any multiple choice question to select or set which responses are displayed in a subsequent list, array or multiple choice question.
- Multiple choice
- Multiple choice with comments
- Multiple short text
- Multiple numeric
- Array (5 point, 10 point, Yes/No/Unknown, Increase/Same/Decrease, Column)
- Array (Dual Scale, Text, Numbers)
- Ranking
Furthermore, each of these question types can be filtered.
The only exception is Array (Column), which can filter other questions, but not itself.How to set a filter
To set a filter, enter the question code of a multiple options question in the array filter box of the question you are currently editing. The respective question will be used as the source of information for the current question, the selected answers from the previous question being retrieved and used as answer options for the current question. For example, if your source multiple option question code is "Q1", enter "Q1" into the 'Array Filter' box to start the filtering process of the answers. Only the answer options that are selected in question Q1 will be visible in the array_filter-ed question.
Cascading
The selected options can be displayed in cascade. This means that you can select a question which filters another question, which filters another question, and so on.
Array filter example
Let's take a look at the following example to better understand the power of this setting:
In the screenshot from above, we got two questions. The first one is a multiple short text question type, while the second one is an array dual scale question type. The answers you provide in the first question will be listed in the second one. Technically, the answers you provide to the subquestions from the first question are filtered and displayed in the second question.
This example can be downloaded from the following link: limesurvey_group_32.lsg. Import this question group into your LimeSurvey installation.
SPSS export scale type (scale_export)

Array filter style (array_filter_style)
Description
This function allows you to choose how the array filtered subquestions are displayed. They can either be "hidden" or "disabled".
Available options
- Hidden (default) - if this option is selected, then the previously selected subquestions will not be displayed in the second question.
- Disabled - if this option is selected, then the previously selected subquestions will be greyed out and become unselectable.
Example
If you wish to use the "disabled" option, then the previously selected subquestions will be displayed like this:
