Snap Desktop has the facility to scan in a suitable questionnaire created in software other than Snap XMP. To ensure the questionnaire’s design is suitable for scanning, the following guidelines include the special requirements that are necessary to ensure the smooth and accurate scanning of the forms.

Questionnaire design recommendations

Box shapes

Square or rectangular boxes including those for open ended questions

Box shading

Flat boxes without shadows

Box colouring

The area within a surrounding code box must be white or a very pale shade.

Spacing between and around boxes

A minimum of 0.05″ margin between code leaders and code boxes, a minimum of 0.05″ margin between code boxes and code values and a minimum of 0.05″ vertical margin between code boxes and texts or other code boxes

Scanning design dos and don'ts

Creating the survey

The survey variables need to be set up before the scanning definition process is started. The layout of a questionnaire does not have to match that of the original questionnaire. You do not have to set up variables for every question as there may be some questions, which you do not wish to analyse.

  1. From the Survey Overview SurveyOverviewIcon.png window, click Online Surveys 5.OnlineSurveysIcon.png to show the online surveys.
  2. Click 1.NewSurveyIcon.png to create a new online survey.
  3. Choose the Scanning survey template, which is supplied with Snap, as a starting point for the new scanning survey and click Next.
  4. In the New Online Survey dialog, enter a name for the survey and select the location of the survey. Click OK. This creates the new survey.
  5. You can now enter the questions in the Questionnaire window. There is no need to enter a Title or Sub Title, just select the appropriate question style for each of the questions from the external questionnaire.
  6. Set your Response types and add any Routing if required. There is no need to customise.

Further details of creating a scanning survey can be found at Setting up the online survey framework for scanning and Designing your scanning questionnaire.

Matching a scanned questionnaire to variables in Snap

The Define external questionnaire process allows you to match questions and codes on a paper questionnaire with appropriate variables in the survey. All code boxes that are to be scanned must be defined using the Define external questionnaire process. Using Define external questionnaire locks the questionnaire for scanning.

Note. If you have used Define external questionnaire to specify the location of the boxes you should NOT, under any circumstances, use Calibration, as this will overwrite the definition you have created.

The next step is to scan a blank copy of the questionnaire from a paper copy of an image file.

  1. Open the Questionnaire window QuestionnaireIcon.png .
  2. Click on the Define external questionnaire button in the Questionnaire window toolbar. This appears at the end of the toolbar for Scanning surveys. QuestionnaireTB.PNG
