Self Report Flashcards
What are the two main self report techniques?
-Questionnaires
-Interviews
What are the two types of questions
-Open questions
-Closed questions
What is an open question
Participants can answer in whatever style they choose.
Qualitative Data
What is a closed question
Give the answers. Participants choose the most appropriate answer for them
Quantitative Data
What are the advantages of Closed questions
- Easier and quicker for participants to respond
-The data collected is easy to compare and analyse
-Quantitative data is provided
What are the advantages of open questions
-Provides more rich detailed data
- doesnt force participants to give a particular response
- Qualitative data
What are the disadvantages of Closed questions
- Can force participants to choose an option which isn’t for them
- Lacks reasons for why they selected the option they did
What are the disadvantages of Open questions
-Harder and slower for Participants to respond (time consuming)
-Data collected is hard to compare and analyse
-subjective (open to interpretation)
- responses may not be relevant to what the researcher is interested in
What are rating scales
a scale where the participant marks at an appropriate point along a numerical dimension to indicate the direction and strength of their attitude
Strength and weaknesses of the rating scale
Advantages
-more detailed than yes or no
-quantitative data
-easily repeated
Disadvantages
-no reasoning behind the option participant chooses
-tendency to choose middle to not seem too extreme
-interpretation of scale is not consistent with each participant
What is a Likert Scale
likert scales comprise of a number of statements for each of which participants indicate wether they strongly agree, agree, undecided, disagree, strongly disagree.
Strengths and weaknesses of a likert scale
-Greater level of understanding and feelings (make results more reliable)
-Subjective (the numbers may mean something different things to different people)
-Socially desirability Bias (portray themselves positively)
What is Response Bias
-People answer incorrectly or falsely to questions
-E.G. picking the same option all the way down
How to deal with Response Bias …
Can reverse the questions to see who’s response bias(improves reliability)
What is the Split half method?
Ask similar questions to see if participants answer similarly to before- check reliability
What are semantic differentials?
-Asks people to place themselves on a line between two extremes
- often used to measure attitudes
- the extremes can be reversed to catch people out who aren’t reading the questions properly
What are the types of interviews
-Face to face
-Over the telephone
-Structured (plan what to ask)
-Unstructured (don’t plan what to ask)
-Semi-structured (plan what to ask then may ask other things)
What are leading questions ?
Forcing respondents to give particular reply- researchers not usually aware of this (decrease validity- not their true feelings)
Strengths of Self Report.
-Allow participants to give views rather than inferring from observation
-Can study large samples easily and quickly
-Examine large number of variables
-Ask people to reveal behaviour and feelings experienced in real life situations (ecological validity)
Weaknesses of Self Report
-Social Desirability Bias
-Questions might not be clear (validity issues)
-Response rates can be low
-Leading questions
-Quantitive data doesn’t give a lot of information about the reasons
-Qualitative data hard to analyse
-Reliability and validity issues.
How to Improve reliability
- Make sure questions aren’t ambitious and clarify exactly what they’re saying
-In interviews, train interviewers to ensure they ask things in the same way
How to Improve validity
-Avoid leading questions
-Concurrent validity- doing two things that measure the same thing to compare the results - if they’re similar its measured
-Open questions could be added to allow respondents to expand on their answers
- Confidentiality allows them to be more truthful
Strengths of Structured Interviews
- Standardised format- All participants are asked the same questions
-Interviewer is present to avoid misinterpretation of the question
Weaknesses of Structured Interviews
-Interviewer bias (may alter tone of voice) decrease validity
-Respondents may be Social desirability bias in-front of the interviewer
-Lack flexibility, can’t expand on their response
