Assessing Validity Flashcards
concurrent, predictive , face and content validity
face validity
whether the test appears (at face value) to measure what it claims to, and hence is objective. Tests where the purpose is clear, even to naïve respondents, are said to have high face validity
predictive validity
the degree to which a test accurately forecasts a future outcome on a more broadly related topic
content validity
objectively checking whether the method of measuring behaviour is accurate and decides whether it is a fair test that achieves the aims of the study (internal validity). This can be achieved by asking an expert in that specific area of behaviour to check the validity
concurrent validity
validating a measurement by comparing it with an
established measurement that has known validity. If similar results occur on
both tests, then the new test has concurrent validity. If not, then the new test would have to be redesigned and tested.
construct validity
looks at whether the overall results reflect the
phenomena as a whole (external validity). It is achieved by checking the
existing definitions of the behaviour being studied and redesigning the test if
it measures a different construct.
how is researcher bias overcome
- double blind procedure
2.single blind procedures - giving participants anonymity and confidentiality
