Survey Methods Flashcards
What are the characteristics of questionnaires? (4)
- A schedule (list) of questions asked to the PPT
-can be same type of question or made up of several, e.g open and closed questions
-usually 30 mins to an hour
-involves PPT’s opinions, ideas and thoughts.
What are the strengths to questionnaires? (5)
-Given to lots of people quickly
-cheap to run
-easy to replicate so can be easily checked for replicability
-anonymity enables ppts to be more honest, they wont be affected by SDB
-requires less training and experience than interviews
What are the weaknesses to questionnaires? (4)
- response rates can be quite low (often around 30%
-ppts who respond can be a biased sample as they may have more free time/ interest in the topic.
-hard to generalise results as they may not represent the target population - no follow up questions can be asked
What are leading questions?
These give away the answer that you are wanting
What are ambiguous questions?
These have two/ several meanings when you may have only planned for one.
What are double barrelled questions?
These contain two questions in one.
What are structured interviews?
These involve asking a person questions like it were a questionnaire.
What are the strengths to structured interviews? (2)
quicker to run and needs less training
easier to replicate and check test re-test reliability than unstructured interviews as you can easily hand out the same questionnaire again.
What are the weaknesses for structured interviews?
Some people may show Social Desirability Bias or the Hawthorne effect.
What are unstructured interviews?
These don’t use set questions– follow up questions are asked after a first main one.
The interview flows like a natural conversation.
What are the strengths to an unstructured interview?
Often has high ecological validity as it is a real person being asked these questions
Easier to tell if someone isn’t being truthful
What are the weaknesses to unstructured interviews? (6)
-hardest to run out of three interview types as you need most training
-easy to not have asked the right questions, as there is no set list
-to ask the right questions requires lots of expertise and experience
-takes a long time to analyse the interview than interview itself (often takes x10 longer)
-each ppt is different, making comparison difficult
-higher chance of SDB.
What is a semi-structured interview (clinical interviews)?
This involves starting with a schedule of questions, then asking unstructured follow up questions
What is the main strength to semi-structured interviews?
-unlike unstructured interviews, they are often easier to compare the answers between ppts as there is a schedule initially.
what are the weaknesses to semi-structured interviews?
-requires lots of training to run
-chance of SDB
What are semi-structured interviews also called?
clinical interviews
what are follow up questions?
An interviewer adds an extra question in to the interview to gain more information after the PPT has said something of interest.
What are the characteristics of closed questions?
-collects quantitative data
-either a simple yes/no, a section of different options or a questionnaire
-often have an instruction to tick, cross out or circle the correct or most suitable answer.
