Every questionnaire, regardless of the chosen mode, is programmed in a single application, using the same user interface.

If you have designed your study as a CATI project then the system associates the project automatically with a CATI specific template. To create an online survey the only thing needed to make this happen is to select a responsive template you would like to use for this particular questionnaire from the drop-down.

All Nebu Dub InterViewer users can choose among twenty look & feel versions of the brand new responsive template to match their preferences about the look and feel of a survey. Please note that Nebu Dub InterViewer allows its users to apply custom adjustments in the look and feel of each template, like color, font type, background picture and logotypes to best reflect brand identity or a topic the survey is related to. Nebu's Professional Services team can also help you develop a custom template to match your specific needs.

Nebu Dub InterViewer supports quite a number of question types out of the box. A "question type" in Nebu Dub InterViewer represents the resulting data format. To keep a survey fun and engaging, the tool allows to play with questions' look and feel. For example, a numeric question can be displayed to respondents as a ranking, a slider, etc.

• Single Grid
• Multiple Grid

All questionnaires created with Nebu's responsive template are accessible on all computer and mobile devices. 

With Nebu Dub InterViewer you have two ways of creating a questionnaire. The first and most popular way to interactively create a questionnaire is described below in this section and is accessed via the User Interface. The second way is to import a questionnaire from a formatted text document (please note that you have to be a registered Nebu user to be able to access this more detailed technical article.)

Nebu Dub InterViewer users can create a structure of a survey with so-called forms. The interface consists of the main menu with all possible forms and three windows: the first one with the structure of the entire questionnaire, the second one where a user can adjust settings per a form, and the third one that stores all answer options per chosen question. This window may also contain some action forms attached to an answer (like excluding a respondent automatically if they have refused to answer any more questions, by routing them to a specific end of questionnaire form.) 

All forms available in Nebu Dub InterViewer are grouped into four categories: Question Forms, Action Forms, Special Question Forms, and Telephonic Action Forms. 

Nebu Dub InterViewer offers a wide range of options to adjust Question Forms according to your needs, for example by:

• Randomizing
• Rotating
• Sorting
• Reversing
• Dynamically adding new items
• Defining minimal and maximal count
• Creating inclusion/exclusion lists.

Action Forms provide valuable additions to your questionnaires, for example by:

• Creating introduction and end-of-questionnaire pages with instructions for an interviewer/respondent (if you use hybrid modes it's also possible to hide some part of the text, so a respondent will not see interviewer's instructions if he or she requests to complete the interview via an online completion format)
• Allowing to send messages to respondents at any time during the interview
• Using a block control form which creates a set of questions that will be asked for particular statements, items or answers that were given in a preceding question
• Building a dynamic response code list that can be used in other similar questions (of up to 5000 response codes)
• Executing a great number of specific operations with values or variables, from simple text substitutions to highly complex calculations
• Checking quotas and automatically creating routings in the questionnaire based on certain quota cells being filled or not
• Adding a timestamp when the interviewer or the respondent passes a particular form/part of the questionnaire
• Skipping certain forms or series of forms depending on specific conditions
• Allowing respondents to visit an external page, such as another questionnaire, youtube video or any other website at a certain point in the questionnaire, and then proceed with the questionnaire afterward.

Telephonic Action Forms specific to the CATI mode help to increase interviewers productivity for example by: 

• Providing an out-of-the-box introductory survey screen that displays instructions for an interviewer alongside the details concerning the respondent such as their name and phone number
• Codifying reasons for respondents' refusals, allowing interviewers select follow-up actions like, making an appointment and adding comments to help the next interviewer contacting the right respondent
• Disconnecting the telephone line at the end of the interview, without terminating the questionnaire, giving interviewers an option to evaluate the interview or to edit open-ended questions
• Allowing interviewers to add a new sample record while conducting an interview, so that an interviewer can ask questions to other household or office members.

Nebu Dub InterViewer supports all quantitative interviewing modes. Users can create as many questionnaires as they wish for telephone, online, mobile, f-2-f projects (the pricing is based on the actual usage of the system). It is also possible to create just one questionnaire and make it available for a specific mode or multi-modes to:

• Streamline processes,
• Decrease the number of possible errors,
• Facilitate further data processing, and
• Conduct multi-country research projects.

Nebu Dub InterViewer provides its users with powerful support for multilingual research projects. The tool works on desktop computers, tablets or a Raspberry Pi devices.) International projects can be managed centrally or locally, and interviewing call times are automatically done in the respondents' time zone.

Once a research project is designed (you know what to ask, whom to ask, how to get relevant answers, etc.) users can create one questionnaire that will be available centrally with a few programmed adjustments to meet the needs of local partners taking part in the study.

Often there are differences between cultures and markets, e.g.tastes, education systems, beliefs, language, sense of humor, the list is endless. This can result in a need to including/excluding specific questions for the various language versions of your questionnaire. This can all be covered using Nebu Dub InterViewer. The tool allows creating, in one common questionnaire, conditions regarding which questions will be displayed to interviewers/respondents based on a questionnaire's chosen language or based up on other quotas targets. 

The tool currently provides multilingual questionnaire support for 33 languages: Arabic, Bulgarian, Chinese (Hong Kong SAR, PRC), Chinese (Mandarin), Croatian, Czech, Danish, Dutch, English, Estonian, Finnish, French, German, Greek, Hungarian, Indonesian, Italian, Japanese, Korean, Latvian, Lithuanian, Norwegian, Polish, Portuguese, Rumanian, Russian, Slovak, Slovene, Spanish, Swedish, Thai, Turkish, Vietnamese. This list can easily be extended based on a specific request.

Specific character sets (like Chinese, Arabic, etc.) are supported, as well as the right-to-left written texts.

When scripting a survey, the translations can be added in several different ways:

• Translations can be stored in template questions in a library and they are automatically brought in when copying a question from a library to the survey-script.
• Translations can be added to the design screen.
• Translations can be added when importing from a formatted text file.
• The survey can be built in a default language, then with a push of a button be exported to an Excel file, where the translations can be added in designated columns and then be imported from the Excel file. Dub Question automatically knows where to put the translations.

There are no limitations to the number of translations that can be added to one survey.

Nebu Dub InterViewer provides its users with one dataset for all of your international interviews. This is a huge help in analyzing the answers and uncovering multicultural similarities, but equally in pinpointing differences that are critical, especially the ones that if unheeded will become a barrier to success.
