RELIABILITY
Consistency of measurements.
Reliability of observations assessed with inter-observer reliability, which should be >.80.
Improved by better operationalisation of behavioural categories and by training observers.
Reliability of self-report assessed with test-retest: repeat test with same participants over a short interval of a few weeks.
Improved by reducing ambiguity in questions.
Reliability in experiments may relate to how the dependent variable is measured (e.g. using observations or self-report).
Improved using standardisation of procedures in order to be able to repeat method with all participants.
