What is a Questionnaire?
Questionnaires allow you to gather information from your participants without reaction time data.
Questionnaires consist of blocks of Rich Text content (which can be a mixture of Markdown and/or HTML) and Response widgets, which offer a range of ways for participants to be asked questions.
Questionnaires can be used to collect demographic information or information about your participants that is specific to your study or the task itself.
Questionnaires can also just be used to display text, images and videos to participants, and so can be used to provide additional direction within an experiment.
For advanced users; information from a questionnaire can be used in conjunction with a 'Branch' Tree Node to change which path a participant takes through your Experiment Tree.
A question about a participants' first language could be used to give them a version of the task in their first language. Alternatively, you might exclude someone entirely if a particular language is not their first language.
How do I start a new questionnaire?
A new questionnaire can be created in a project by pressing the 'Create' button and selecting 'Questionnaire' and 'Create New'.
On the next screen, choose a name for the questionnaire and then press 'OK.'
When choosing a name for your questionnaire, try to make it something unique and memorable - a name you would easily associate with the task contents.
You will use this name when adding your questionnaire to an experiment or searching for it in your library. It is also the name people will see if you share your questionnaire with them, so its important that they would be able to recognise it easily too!
You can add descriptions to your Questionnaire in the Settings menu, use this feature to add a short reminder of what your questionnaire is about.
What is the Questionnaire Builder and How do I use it?
In Gorilla you create questionnaires using the Questionnaire Builder.
The Questionnaire Builder interface is divided into two major sections:
To learn how to build a Questionnaire using the Questionnaire Builder click here.
How Do I Build A Questionnaire?
A Questionnaire is built in a similar way to creating a task with the task builder, though the interface is much simpler. If you need to review the questionnaire-builder interface click here.
When building a new questionnaire the first step is to add a Questionnaire Widget, here's how:
There are many different Questionnaire Widgets to choose from, allowing you to present and/or gather data from your participants in a variety of different ways.
Once you've added a Questionnaire Widgets to your Questionnaire, it will appear on the left-hand side.
The Widget will appear with a title bar displaying the name of the widget type, and a list of options beneath it.
Enter content for your Widget and you will see it displayed automatically on the right-hand side.
When you have added a few widgets modifying your questionnaire is straightforward:
On the title bar of a widget, there are two arrows, which can be used to reorder your questionnaire widget. There is also a cross, which allows you to delete the selected widget from your questionnaire entirely.
When you are happy with your questionnaire, or wish to save your progress, press the green 'Commit Version' button. You will then be able to use your Questionnaire in your experiments.
You can find out more about Questionnaire Widgets here. If you have a specific question about a particular Questionnaire Widget the best place to look is in the Questionnaire Widget Tooling Reference Guide
What are Questionnaire Widgets?
Questionnaire Widgets are the building blocks of questionnaire creation. There are currently 18 different Questionnaire Widgets for you to choose from, allowing you to present and/or gather data from your participants in a variety of different ways.
You can create any questionnaire you wish by simply combining Questionnaire Widgets in different orders.
Learn how to add Questionnaire Widgets into your questionnaires here.
There are also the Script Widget which is a stand-alone widget useful for all questionnaire related coding, and the Switch Widget.
The Switch Widget combines with a Switch Node in the Experiment Tree, and either a Task containing a Switch Zone, or another Questionnaire containing a Switch Widget, to allow participants to switch between two tasks.
Below are the Questionnaire Widgets you will find in Gorilla's Questionnaire Builder:
|Rich Text||Consent Box||Dropbox||Mixed Entry||Slider|
|Image||Text Entry||Checklist||Date Entry||Rating Scale/Likert|
|Page Break||Comment Box||Radio Buttons||Time Entry||Ranking|
What are Content Widgets
Content Widgets allow you to add content to your questionnaire in the form of, text, images, links etc. For example, you may wish to add text content such as a title for your questionnaire or a set of instructions for your participant.
In the content box of the widget you add the text you wish to be displayed. In the example above you can see that the content has been modified using 'markdown. All text content can be formatted and stylised using markdown and/or HTML, this means you can easily make your questionnaire look exactly how you wish!
You can find out more about markdown here.
What are Response Widgets?
Response Widgets allow you to ask questions and record the responses of your participants. You can always recognise response widgets because they are the only widgets which have a 'Key' configuration setting.
In the example above you can see that below the response widget title there is a list of configuration settings. While most settings may be self-explanatory, you can always find out more about each and every widget in the Questionnaire Widget Tooling Reference Guide.
Other than the 'Key' there are two other configuration settings, pictured in the example above, which the majority of response widgets share: 'Allow Missing' and 'Write to Embedded Data'.
It is always a good idea to rename your keys from their default values, to something more relevant.
You will see these keys as headings when viewing the downloaded data from the questionnaire. Thus they will be most useful to you if they are easily recognisable.
As space is a premium in Excel, It is a good idea to use 'camelCase' or 'PascalCase' to remove the white space from your key names:
This is what camelCase looks like: hereIsAnExample. This is what PascalCase looks like: HereIsAnotherExample.
What are Layout Widgets?
Layout Widgets allow you to customise how your questionnaire is presented to a participant.
The Page Break Widget is used to separate out your questions across multiple pages.
Notice how in the above example there are no configuration settings or content inputs in this Layout Widget.
That because all Layout Widgets are controlled in the Options menu found under Settings which is located next to the 'Preview Questionnaire' button on the top-right of the Questionnaire Builder.
What is the Script Widget
The Script Widget allows you to add some customised code to your questionnaire in order to do post-processing of your questionnaire data.
The Script Widget can be useful if you wish to create your own scoring system for your questionnaire responses, or else alter the standard scoring of the Widgets. You may also wish to calculate overall scores for a participant which you later use to branch participants in your experiment. You can view a demonstration of this here
Alternatively, if you already know how to code, you may prefer to learn about the Script Widget via this
Classic Example: Big 5 Personality TIPI
When you are ready to start coding your own scripts be sure to also check out the Gorilla API.
If you don't know how to code but have an idea which you'd love to see coded-up ask Gorilla to code for you! Just drop us an email asking about our bespoke coding services.
How Do I Use a Questionnaire As Part Of An Experiment?
The steps for putting your Questionnaires into an experiment are the same as when including your Tasks in your experiments:
If you would like more detailed infomation on adding Nodes to your Experiment Tree read here
You can find out more about Building Experiments and using the Experiment Tree here.
As well as gathering data on your participants a questionnaire, when used in conjunction with a Branch Node, can be used to influence the progression of other tasks or your experiment as a whole. For example, you could end an experiment early or make a following task harder or easier depending on a participants answers.
In order to do this you must check the 'write to embedded data' option in your response widgets. Find out more about Embedded Data and how to use it here.
How Do I Use Embedded Data?
Embedded data is Gorilla's way of enabling you to reuse the data entered by a participant in a questionnaire elsewhere in your experiment.
Why would I use Embedded Data?
Here are some examples of when to use embedded data:
In order to implement any of the above examples there are two important steps:
This tells Gorilla to temporarily remember this data and allow access to this embedded data from your questionnaire in the rest of the experiment.
The embedded data can be accessed by using the 'key' that was set for the response widget of interest.
Note: Writing to Embedded data will not effect what is recorded in your 'Metrics Spreadsheet'.
The Branch Node is a control node in the Experiment Tree which tells Gorilla how to decide which path a participant should take through your experiment.
Inside your Branch Node you should configure the 'Property' to match the same name as the 'key' of your embedded data. This tells Gorilla where to find your embedded data. Then you need to set the rules for your Branching and enter the 'Value' for each of your branches. The values will correspond with the answers offered in the questionnaire configuration.
The best way to learn about using the Branch Node in conjunction with embedded data is to look at this Demo.
You can find out more about the Branch Node configuration settings in the Experiment Tree Tooling Reference Guide.
If you would like to learn more about Control Nodes and the Experiment Tree take a look in the How To: Experiment Guide.
Remember: All names are case-sensitive
When choosing a name for your Key try to make it something unique and memorable - a name you would easily associate with the task contents.
A good way to make sure you are using the same word is to copy and paste the Key from your questionnnaire straight into your Branch Node.
