Designing a Questionnaire

Three consecutive slides carry twenty separate instructions about building a questionnaire, in no stated order and with four of them repeated. Sorted into the sequence you would actually work through, they amount to a usable working method with three holes in it.

In brief

  • The guidance runs across three slides: nine questions to ask yourself, six points that "should be observed", five reminders.
  • Two of the six design points are the same requirement stated twice, so the list of six contains five distinct rules.
  • Four of the five reminders repeat instructions already given, and the fifth introduces a second word for a fault the deck has already named differently.
  • Length is never stated. No number of questions, no completion time and no page limit appears anywhere in the week.
  • A pilot stage is required in the strongest terms the deck uses — and the words pilot, pre-test and trial appear nowhere in it.

What the design guidance consists of

The design content is three slides deep and follows the two slides that argue questionnaires are the least satisfactory way of collecting anything, covered on Questionnaires and Response Rates. Before it sits the survey construction slide, which supplies the week's only build order: questions and response categories, then background information and instructions, then organisation and length, then layout and design.

Stated once before you use any of it: the week's single learning objective is to evaluate methods of data collection, and the delivery audit records that verb as undelivered. This is instruction in building one instrument, not grounds for choosing it over another.

From the source

The framing sentence for the design points

"If a questionnaire is to be used, either as a postal/digital questionnaire or as a basis for interviewing, the following points should be observed in its design."

This is one of the few places in the week where the material issues a requirement rather than a prompt. It also settles a question the deck otherwise leaves open: the same design points govern a questionnaire that a respondent fills in and a question set that an interviewer works from.

Nine questions to ask before you draft anything

The first slide is prefaced "First of all, ask yourself:" and lists nine questions. They are reproduced below in the order printed, with what each one is really deciding and what the material does with it afterwards.

THE NINE DESIGN QUESTIONS, AS PRINTED

Question, quotedWhat it decidesWhat the source supplies after asking
"What is the question content, scope and purpose?"The subject matter and its boundaryNo method for setting scope; no link back to the research question
"What response format can I use to collect the best information from the respondent?"Whether answers are fixed, ordered, scaled or openThree formats appear five slides later, under levels of measurement. The connection is never made
"Does my population have knowledge of the topic?"Whether your respondents can answer at allNo screening question, no filter, no test of competence to answer
"Does my population have good reading skills?"Whether the instrument is readable by the people receiving itNo reading-level guidance, no plain-language rule, no alternative mode
"How should I word the question to get at the issue of interest?"WordingA separate slide of six wording checks, treated on the wording page
"What facilities and timeframes do I have?"Feasibility of administrationNothing further; the same concern appears in the method-selection questions four slides earlier
"How complex is the information I want to collect?"Whether a questionnaire can carry it at allNo complexity threshold, and no statement of when to switch instrument
"Do my questions pose sensitivities e.g., asking about age, income?"Whether people will answer honestlyTwo examples — age and income — and no procedure for either
"What types of methods have been used in research projects similar to mine?"Whether to follow precedentNo search method; the same concern is raised in the method-selection slide

Nine questions are printed. The source states no count, does not number them and does not say which are answered before which.

Source gap

Twenty-three questions across three slides, with no consolidated list

This is the deck's third "ask yourself" set. Eight questions govern choosing a method, nine govern designing a questionnaire, six govern wording — twenty-three self-directed questions in one week, with no consolidated checklist, no ordering, and no statement of which apply when.

The sets also overlap unreconciled: question 5 duplicates the whole of the wording slide, and question 9 duplicates the method-selection concern raised four slides earlier.

Caution

Question 4 raises literacy and the material supplies no remedy

"Does my population have good reading skills?" is a serious design constraint and nothing follows it. No reading level is named, no plain-language rule is given, and no alternative administration mode is offered.

The wording slide later asks whether a question "can be misinterpreted by a non-English language speaker" and likewise attaches no remedy. Two constraints are raised as checks and neither is answerable from within this material.

Six design points, five distinct requirements

The second slide is the operative one. Under the heading "Questions should be", six points are printed in this order.

  1. "short and simple. It is far better that there are many short questions than a few long questions"
  2. "unambiguous"
  3. "as short as possible"
  4. "neither irrelevant nor too personal"
  5. "not leading i.e. one suggesting the answer" — followed by a worked example of a question that suggests the answer yes
  6. "designed so the questions fall into a logical sequence. This enables the respondent to understand its purpose"
Source gap

Points 1 and 3 are the same instruction

"Short and simple … many short questions than a few long questions" and "as short as possible" state one requirement twice, as two separate items in a six-item list. Count the points and you get six; count the distinct requirements and you get five.

This matters only in one way, and it is worth a moment: if you are using the list as a design checklist, do not read the repetition as emphasis on brevity over the other four rules. The source gives no priority between them. It has simply listed one rule twice.

Point 5 is the deck's definition of a leading question — "one suggesting the answer" — and it comes with the only worked fault example in the design material. Leading questions, and the other wording faults, are treated with worked repairs on The Wording of Questions, which is the better-developed half of this topic.

Source gap

"Unambiguous" is required and no test for ambiguity is given

Point 2 is one word long. Nothing in the week tells you how to detect an ambiguous question, and the only operational aid anywhere is the wording slide's instruction to rehearse "with someone else before you begin" — which is not linked to this point and is not called piloting.

Ambiguity is not something a designer can see in their own draft, which is why the silence here is a working problem rather than a pedantic one.

Five reminders, four of which you have already been given

The third slide is headed "Remember to" and lists five items. Set against what has already been said, four are restatements.

THE FIVE REMINDERS AND WHERE EACH WAS ALREADY STATED

Reminder, quotedStatusWhere it was already covered
"Sequence questions appropriately"RepeatDesign point 6 — logical sequence
"Create a clear and easy to follow layout"RepeatThe survey construction slide — "Determining layout and design"
"Be careful not to create misleading questions"New word, existing faultDesign point 5 called it "not leading"; the wording slide asks whether a question is "confusing or misleading"
"Use language respondents are familiar with"RepeatDesign questions 4 and 5, and the wording slide's ban on jargon and acronyms
"Thank respondent for their participation"New to questionnairesRepeated later as an interview instruction — "thank them for their time"

Only the last reminder adds anything to the questionnaire guidance, and it is the only statement in the whole design sequence about what surrounds the questions.

Source gap

"Leading" and "misleading" are used interchangeably and are different faults

The design slide prohibits questions that are "not leading i.e. one suggesting the answer". The reminder slide prohibits "misleading questions". The wording slide asks "Is the question confusing or misleading?".

A leading question pushes the respondent towards a particular answer. A misleading question gives the respondent a false impression of what is being asked. The deck uses the two words for what appears to be one fault and never distinguishes them, so a reader cannot tell whether three separate faults are being named or one fault is being named three times. Both readings are available in the source and this page does not choose between them.

The sequence you would actually work in

The source lists twenty items and orders none of them. The sequence below is this page's arrangement of the source's own material — every item comes from the week, the ordering does not. It follows the one build order the week supplies and slots the design points and reminders into it.

The source's instructions, sorted into working order

  1. Settle content, scope and purpose

    Design question 1. Decide what the instrument is for and where it stops. Nothing in the material links this back to your research question; do it anyway.

  2. Check the population can answer

    Design questions 3, 4 and 7 — topic knowledge, reading skills, complexity. If any answer is unfavourable, the instrument changes rather than the population.

  3. Draft questions with their response formats together

    Design question 2, and the construction slide's first activity. The formats the material offers are on Levels of Measurement in Structured Questions, and the choice between fixed and open answers is on Structured and Unstructured Questions.

  4. Apply the five distinct design rules

    Short and simple; unambiguous; neither irrelevant nor too personal; not leading; in a logical sequence. Applied to each question individually, then to the set.

  5. Work the wording

    Design question 5, and the six checks on the wording slide. This is where most of the week's genuinely useful content sits.

  6. Order the questions and fix the length

    Design point 6 and the construction slide's third activity. A principle is given for order and no figure at all for length.

  7. Write what surrounds the questions, lay it out, then rehearse

    Background information and instruction, the closing thanks, a clear and easy-to-follow layout, and the rehearsal the material calls essential and does not describe.

Order, length and the covering explanation

Three design decisions deserve separate treatment, because the material's coverage of them ranges from a single principle to nothing at all.

WHAT THE MATERIAL SETTLES AND WHAT IT LEAVES OPEN

DecisionWhat the source saysWhat it does not say
OrderQuestions should "fall into a logical sequence", which "enables the respondent to understand its purpose"What makes a sequence logical, and how it resolves against the instruction to ask easy questions first and difficult ones last
Length"Working through organisation and length" is listed as a construction activity; many short questions are preferred to a few long onesNo number of questions, no completion time, no page limit — anywhere in the week
Layout"Create a clear and easy to follow layout"; "Determining layout and design"No spacing, numbering, grouping, page-break or response-alignment guidance
The covering explanation"Writing up background information and instruction" is named as a construction activity; respondents are to be thankedNo content, no length and no wording. What a respondent should be told appears only in the interview procedure, not in the questionnaire guidance
Source gap

Two orderings, stated in one week, never reconciled

The design slide requires a logical sequence so the respondent can understand the instrument's purpose. The at-interview slide requires that you "ask easy questions first and lead up to the more difficult ones at the end".

Difficulty order and logical order frequently disagree — the hardest question in a set is often the one the logic wants early. The material states both, in one week, for instruments the design slide says are governed by the same points, and never says which prevails. Both are recorded; neither is preferred.

Note

On what respondents are told

The only statements in the week about what a respondent is told before answering sit in the interview slides — give written information on the project background and purpose, and explain your purpose and methods briefly. The questionnaire slides say only that background information and instruction must be written up. For a self-completed instrument the material gives you the task and none of the content.

The pilot stage the source requires and never describes

From the source

The instruction, quoted exactly

"It is essential that your wording is thought through carefully and rehearsed with someone else before you begin."

This opens the wording slide, and "essential" is the strongest word attached to any instruction in the week.

Source gap

The strongest requirement in the week is also the least specified

The words pilot, pre-test and trial appear nowhere in the week. What the material asks for is a rehearsal with "someone else", and it states no number of rehearsers, no procedure, no criterion for a successful rehearsal, and no revision loop afterwards.

That leaves the reader with a requirement they cannot fail and cannot pass. It also leaves the only test for the ambiguity that design point 2 prohibits unspecified, since rehearsal is the sole mechanism the week offers for detecting it.

Practice note

A minimum rehearsal that satisfies the instruction

The source does not prescribe any of this; it is offered because the requirement is stated and unspecified. Sit with a small number of people who resemble your respondents rather than colleagues who know the project. Have them complete the instrument in front of you without help, and time it, since the material gives you no length and you will need your own. Note every point at which they hesitate or re-read. Then ask them to tell you, in their own words, what each question was asking — the gap between their reading and your intention is the ambiguity that design point 2 prohibits. Revise, and record what changed, because that record is your only evidence the rehearsal happened.

Where personal and sensitive questions land

The material takes three different positions on personal questions across three consecutive slides, and a reader who needs sensitive data has to notice all three.

The three positions, as printed

  • Design question 8 treats sensitivity as something to be considered: "Do my questions pose sensitivities e.g., asking about age, income?"
  • Design point 4 prohibits it outright: questions should be "neither irrelevant nor too personal".
  • The wording slide treats it as a matter of phrasing: "Is the wording sensitive? Not too direct? Not too personal?"

What none of the three supplies

  • Where the line between personal and too personal falls
  • Any procedure for asking about age or income, the two examples the material itself raises
  • Any option to make a sensitive item optional, banded or anonymous
  • Any connection to consent or confidentiality, named only in the interview slides
Caution

If your project genuinely needs a sensitive item

The material offers a prohibition, a prompt and a wording check, and no way through. That is a real gap: a delivery-side study asking about salary, tenure, performance ratings or reporting lines runs straight into it.

What this material tells you is that the item is a design risk. What it cannot tell you is how to ask it, whether to band it, or what to promise the respondent in return. Take that from your ethics approval process and from published instruments in your field, and do not read design point 4 as permission to drop a question your research question depends on.

Check before you proceed

Before the questionnaire is finalised

Five checks against the source's own rules. Every question is short, unambiguous, relevant, non-leading and in a sequence you can justify. Every response format was decided with its question, not afterwards. You can state how long the instrument takes to complete, from your own timing. The material surrounding the questions is written, not assumed. And the instrument has been rehearsed with someone who is not you, with the changes recorded.

What to carry forward

  1. Twenty instructions across three slides, in no stated order: nine questions, six design points, five reminders.
  2. The six design points contain five distinct requirements — short and simple, unambiguous, neither irrelevant nor too personal, not leading, logically sequenced.
  3. Four of the five reminders repeat earlier instructions; the fifth, to thank the respondent, is the only guidance on what surrounds the questions.
  4. "Leading" and "misleading" are used interchangeably and never distinguished.
  5. Length is never stated. Decide it yourself and record the decision.
  6. The instrument must be rehearsed with someone else — an instruction called essential, described nowhere, and never named as piloting.
  7. Personal questions are prohibited on one slide, prompted on another and reduced to a wording matter on a third. No line is drawn between them.

Frequently asked questions

How many questions should a questionnaire have?

The material never says. Its only statement about length is that many short questions are preferable to a few long ones, and "working through organisation and length" is listed as a construction activity with no figure attached. No number of questions, completion time or page limit appears anywhere in the week, so the decision and its justification are yours.

What order should the questions go in?

The design slide requires a logical sequence that lets the respondent understand the instrument's purpose. A later slide, addressed to interviews, requires easy questions first and difficult ones at the end. The two orderings often conflict and the material never says which prevails, so state your ordering principle in your write-up rather than assuming a reader will infer it.

Does the material tell me how to pilot a questionnaire?

No. It requires that wording be "thought through carefully and rehearsed with someone else before you begin" and calls that essential, but the words pilot, pre-test and trial never appear, and no number of rehearsers, procedure, success criterion or revision step is given. Treat the rehearsal as a minimum and design the rest of the procedure yourself.

Can I ask about income or age?

The material raises both as examples of sensitivities to consider, then prohibits questions that are "too personal", then treats sensitivity as a wording matter — three positions in three slides, with no line drawn between them and no procedure for asking either question. If your research question needs the data, take the technique from your ethics approval process and from published instruments rather than from this material.

Do the same design rules apply to interview questions?

Yes, on the source's own statement: the design points apply whether the questionnaire is used "as a postal/digital questionnaire or as a basis for interviewing". That is one of the few places the material settles a scope question explicitly, although its interview slides then add instructions that pull against the design points on question order.

Where do the response formats come from?

The design questions ask what response format you can use and give no options. Three appear five slides later on a separate slide about structured questionnaires — nominal, ordinal and interval, plus dichotomous items — and the connection between the two slides is never made in the material. Draft the question and its response options together anyway.
