basic mode         advanced mode
This tool is to design VAS that can be used in online studies (e.g., Funke & Reips, 2012; Reips & Funke, 2008). Just follow the 4 steps below to create a VAS for your own online survey. This service is free of charge. If you have any questions or comments, please use the contact form. As this tool is still under development, there may be some minor issues with usability. We are working on it.
1 Set the parameters stated below and click "generate/modify VAS". Default values are pre-selected.
Length:
pixel
Left Anchor:
Right Anchor:
Color: black white

2 Mark the scale and click "read out VAS value" to see the value that will be transmitted. The number of possible values is equal to the number of pixels. Modify the VAS according to your needs and apply changes by clicking "generate/modify VAS".
Click "generate/modify VAS" for a preview.

3 If the VAS satisfies your needs:
and unzip the archive (for example with the freeware 7-Zip [Windows] or Untar [Mac]) on your local drive.
4 Click "go to VAS and download" below and save the following page as ''your_VAS.html" (change the file extention from ".php" to ".html") into the folder "VAS_survey" you have downloaded. Read instructions.txt (included in VAS_survey.zip) to adjust some parameters.
