titleKey Considerations
  • Use only one branch in each condition if possible; if there is an alternative option add this as a statement.
  • Always use the true branch if possible to do so.
  • Questions must remain in the correct order, exactly as they appear in the original questionnaire.
  • Multiple conditions can be derived from one question.
  • Conditions can apply to more than one question.

A Condition is a set of logic that enables questions to be asked only in certain cases.  

A Condition is a set of logic that enables questions to be asked only in certain cases. If a question is asked which is dependent on the answer to another question, a condition is needed. Conditions are usually a narrowing of who answers a question or are directional. Conditions have a 'True branch', where the condition text leading to the next question is true. They also have a 'False branch', where the response to the condition text leading to the next question is false and so does not lead to the next question. Only one branch in each condition is usually used and if possible this should be the true branch.

...

It is common that the condition is included in the same sentence as the question text, in which case this needs splitting to avoid repetition. In Example 1 below, 'If yes,' becomes the condition text and the 'please could you describe' becomes the question text. Note that the 'p' in 'please' is kept in lower case. There is often a natural break such as a comma to help with the decision on how to split text. But if not, then you must use your own judgement.
