What are the 2 main self-report techniques?
Interviews and questionnaires
What are open questions?
They ask a participant to respond to a set of questions but leave a blank underneath the question so participants can answer however they’d like. (Qualitative data)
What are closed questions?
The answers are given to the participant and they have to choose the most appropriate answer for them. (Quantitative data)
What’s an advantage of closed questions?
Easy to put data in a chart since it is quantitative data
What’s a disadvantage of closed questions?
Can’t obtain details from the participant
What’s an advantage of open questions?
You can obtain detailed qualitative data
What’s a disadvantage of open questions?
What is a rating scale?
Involved the participant making a mark at an appropriate point along a numerical dimension to indicate the direction and strength of their attitude.
E.g. How happy are you? (1 = extremely unhappy, 5 = extremely happy)
What are advantages of rating scales?
Simple, easier to answer, easily applicable, quantitative data
What are disadvantages of rating scales?
Can get boring for participant, not enough options so might not reflect their true thoughts, limited data
What are Likert scales?
They comprise a number of statements, for each of which participant indicate whether they:
Strongly agree/Agree/Neutral/Disagree/Strongly Disagree
What is a standard response set and how is it controlled for in a Likert scale?
Standard response set = the tendency to give the same answer to all statements.
Statements are selected so that for half of the statements “Agree” represents a positive attitude and for the other half it represents a negative.
What’s an issue with Likert scales?
The number of intervals to include. Typically, it will contain 5 intervals or an odd number so that a neutral option is possible. With an even number of intervals, the participant is forced to either agree or disagree.
What is a semantic differential?
Semantic differentials use of polar opposite terms. E.g. Good and bad; weak and strong.
In what case will questionnaires often be chosen?
If a researcher wishes to gain quantitative data from a large sample of participants fairly quickly
In what case will interviews be chosen?
If a researcher wishes to gain in-depth qualitative data from representatives of a fairly narrow target population.
What is a structured interview?
The interviewer asks the same questions to each participant in the same order. Closed questions are often used, with the interviewee picking the answer that is closest to their own view.
What are strengths of structured interviews?
What are weaknesses of structured interviews?
What is a semi-structured interview?
The interviewer will have a set of pre-prepared questions to ask and is expected to ask all of them; other questions will be developed during the interview in response to answers given by the interviewee
What are strengths of semi-structured interviews?
What are weaknesses of semi-structured interviews?
What is an unstructured interview?
The researcher has topics to discuss but these don’t have to be in the same order for each participant. The interview is more like a conversation, with further questions being developed in response to the interviewee’s answers.
