Questionnaire development Flashcards
What is important to consider when writing your questions?
- Be specific as you can with the wording
- If a timescale is relevant, be specific
- Avoid double negative questions
- Avoid double barrelled questions (two issues)
- Don’t induce a particular response
- Be ethical
What are the two types of responses?
Open and closed
What is an open question?
- Allows for an unconstrained response
- Gives rich detail about the topic
- However more difficult to summarise
What is a closed question?
- Requires a choice from a predetermined option
- Easy to code and summarise options
Why would you want to create a questionnaire?
- There is no existing measure
- Or an existing measure is flawed
Advantages of open questions
Respondent is not forced to choose between options
Respondent can give explanations for responses
Respondent can give additional information they feel is relevant or important to their response
Disadvantages of closed questions
Respondent can give additional information they feel is relevant or important to their response
BUT: What if that information is not relevant to the survey?
More time consuming for respondent
Analysis is more complex and time consuming for you
Types of closed questions?
- Categorical (male vs female)
- Likert scale
- Ranking (rank from favourite to least favourite)
What should be considered about categorical responses?
- Need to be mutually exclusive (e.g. answers should not cross over)
- If there are multiple answers, need to be clear on how many to select
- Think about if you need a ‘other’ - how would you analyse this?
What is an item?
-asking the responder the extent to which they agree with a statement
I like to have a lot of people around me
Response: “strongly disagree” through to “strongly agree”
What is a question?
Asking a more explicit question
Do you like to have a lot of people around you? Response: “not at all” through to “very much”
What should be considered with likert scales?
- Usually 5 responses but can be more or less
- Can include a neutral but needs to be in the middle
- Can start at 0 or 1 but needs to be consistent
- Do no show the numbers
How can you avoid random responses?
-Acquiescence bias (always agreeing with items)
Ensure the questionnaire is not too long
Positive and negatively marked items
What should be considered with positive and negative scoring?
- Only show participants the words
- Have an equal amount of positive and negative
- Randomise the order of the positive and negative responses
What is a visual analogue scale?
- Lines are typically 100mm
- Provides scores 0-100
- More fine measure, parametric and less prone to responder bias
- Can be positive or negative
