Module 3

Session 3


Overview of session

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.


Session learning objectives

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.


Ugandan national household survey e g unhs2

Ugandan National Household Survey (e.g. UNHS2)

  • The 2002/2003 UNHS survey collected data on:

    • approx.50,000 individuals

    • 9700 households

    • 970 communities

Some considerations when designing a questionnaire

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.


Some considerations when designing a questionnaire1

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.


Some considerations when designing a questionnaire2

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.


  • Some considerations when designing a questionnaire3

    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.


    Some considerations when designing a questionnaire4

    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.


    Some considerations when designing a questionnaire5

    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


    Some considerations when designing a questionnaire6

    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) ?


    Some considerations when designing a questionnaire7

    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?


    Some considerations when designing a questionnaire8

    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.


    Some considerations when designing a questionnaire9

    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.


    Activity

    Activity

    • Read one of two papers.

    • In two groups, prepare a presentation to the rest of the group on the content of your paper.


    Activity1

    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.
