- SELF-REPORT
- Ways in which we can gain data by asking the p's to provide information. About their own beliefs or thoughts.
- RELIABILITY- test or measure is consistent, produce the same results in the same conditions.
- Test reliability through test retest p's respond same test twice in similar way. Split half scores from the first half correlate with that of the second half.
- Maintain high reliability through inter-rater reliability, 2 or more researchers assess same info and correlate ratings
- VALIDITY- the extent to which a technique is capable of achieving the intended purpose.
- Internal validity, refers to test being used whether changes in the DV are due to the IV
- Face validity, whether a measure appears to test what it claims to at face value
- Concurrent validity, does it relate to any existing similar measure.
- External validity, relates to issues beyond the investigation
- Ecological validity, how reflective of real life the study is.
- Population validity, can you generalise the study/sample?
- Internal validity, refers to test being used whether changes in the DV are due to the IV
- Interview self-report method that in which p's reply verbally to questions asked by interviewer
- STRUCTURED - mostly closed q's in fixed order, scripted and standardised,
- WEAKNESS,-quan data does not give in-depth analysis reduced validity
- STRENGTH- standardised as all p's treated in the same way, quan data easy to analyse.
- UNSTRUCTURED, generally start with fixed q but then depends on respondent after that.
- STRENGTH- new themes that rise can be thoroughly explored and give a fuller picture.
- WEAKNESS- Researcher effects can make the interview less reliable.
- Interviews can suffer from demand characteristics in the form of socially desirable ans
- Participating takes a lot of time.Iit may invade privacy, those who volunteer may not be representative. High sample attrition.
- STRUCTURED - mostly closed q's in fixed order, scripted and standardised,
