Simplicity and clarity of the language

Basic principles of questionnaire design usually state next characteristics that are used in well-designed text of the question:

  • Simple words should be used. Rare words, jargon words, technical expressions and foreign words should be avoided
  • Sentence structures should be as simple as possible
  • Questions should be specific and concrete
  • Answer options at one dimensional questions should be comprehensive and mutually exclusive (eg. man/woman) without overlapping
  • Words and sentences with ambiguous meanings should be avoided
  • Negations and especially double negations should be avoided
  • There should be no leading questions
