  1. Questionnairedesign Module 3 Session 3

  2. Overview (of Session) This session starts by introducing some aspects that need to be considered when designing a questionnaire. Participants then have the opportunity to: • explore further ideas • develop a questionnaire for a particular purpose.

  3. Session Learning Objectives At the end of the session participants will: • recognise the importance of clear objectives in a study • be able to develop questions to address objectives • know what is required to be able to structure a questionnaire effectively.

  4. Ugandan National Household Survey (e.g. UNHS2) • The 2002/2003 UNHS survey collected data on: • approx.50,000 individuals • 9700 households • 970 communities

  5. Ugandan National Household Survey (e.g. UNHS2) Households • Info. collected about community • Health facility within 3 km • Bank within 10km • Info. collected about household members • Age • Sex • Schooling status etc. • Info. collected about households • Housing conditions – type of roof, etc. • Household condition - what fuel used for lighting etc. • Household consumption expenditure

  6. Part of UNHS2 questionnaire

  7. Some considerations when designing a questionnaire • Good questionnaire design takes time. There are many aspects to consider e.g. layout, how many and which questions, pilot testing, etc. • Here we discuss a few aspects. • Later in the session you will consider some more.

  8. Some considerations when designing a questionnaire • Study purpose must be clear… • … so that questionnaire can contain correct questions for addressing objectives • … and so that correct summary tables can be produced that address the objectives. • At the planning stage it important to ensure that all the essential questions are included, and that they are well-structured so that good quality data can be collected.

  9. Some considerations when designing a questionnaire • Different types of objective, e.g. • What is rate of unemployment in population? (simple estimation) • What proportion of farmers participate in local co-operative system, and how they compare with those who do not? (relates farmer characteristics to programme) • A study can have more than one objective, or one type of objective.

  10. Some considerations when designing a questionnaire • Are the question variables numeric / categorical / ordered categorical ? Q: What age is the head of the household? Q: What is the household income per week? Q: Do you participate in the local co-operative? Q: How long does it take to get to school ? • 1 = less than 30 minutes, 2 = 30-60 mins etc.

  11. Some considerations when designing a questionnaire • Is the information best collected using a multiple choice question? Q: Do you own a … (tick as many as are appropriate) • Car  • Bicycle  • Boat  • etc.

  12. Some considerations when designing a questionnaire • Do you need to use skip questions Q: Was the person sick in the last 30 days Yes  No  • If yes, give reason (tick as appropriate) • Malaria  • Respiratory infection  • Diarrhoea 

  13. Some considerations when designing a questionnaire • Questions must be clear, simple and unambiguous. e.g. Compare previous question with: Q: What illness did the person suffer from in the last 30 days if they were sick? • How do you interpret no response (blank) ?

  14. Some considerations when designing a questionnaire • Coding must be clear and consistent. e.g. Yes / No always coded 1=Yes, 2 = No (or always coded 0=No, 1=Yes). • Units must be clearly stated, and understandable. e.g. yield of crop measured in… what units?

  15. Some considerations when designing a questionnaire • Organisation of questionnaire • Household and Household member information on different questionnaires (or sections of questionnaire) • Different modules – Education, Health, Household Expenditure etc.

  16. Some considerations when designing a questionnaire • Organisation of questionnaire • Most important questions come first. • Make sure you have enough questions to answer objectives, and a few extra (just in case you need them). • Don’t have unnecessary questions.

  17. Activity • Read one of two papers. • In two groups, prepare a presentation to the rest of the group on the content of your paper.

  18. Activity • In small groups, of 3 or 4, draft a short questionnaire with no more than 10 questions on: What is the opinion of participants on this course on the likely effects in Uganda of global warming. • Identify one or two tables that you would want to present once the data have been collected.
