1. When should I use a questionnaire in my service evaluation?

A questionnaire may be useful to you if…

  • Time and resources are limited
  • You want to collect data from a large number of people
  • You want a few standardised responses
  • You want to find out about knowledge, beliefs, attitudes or behaviour
  • Anonymity is important
  • The Evaluator is unlikely to be present during data collection
  • You want to collect data via post or online
  • You want simple answers to basic questions
  • You need mostly quantitative results
  • You accept the limitations (see box 1)

Questionnaires are not the right choice if…

  • You don’t yet know what the main issues or themes are
  • You want detailed information
  • You want to know about a complex or controversial issue
  • Your respondents may need probing; or not necessarily have an opinion.
  • Your population might struggle with reading or understanding the questions
  • Your population cannot use or access a computer (for online surveys)
