Document Summary
As explained in last class (personality assessments) there are different measures of validity; Face validity: the extent to which a test is viewed as covering the concept it purports to measure. Transparency of a test as it appears to test participants. Predictive validity: the extent to which a score on a scale or test predicts scores relates to real situations. Convergent validity: the degree to which two measures of constructs that theoretically should be related, are in fact related. Discriminant validity: tests whether concepts or measurements that are supposed to be unrelated, are in fact, unrelated. Construct validity: the degree to which a test measures what it claims to be measuring. An example will be used to explain how to asses validity and reliability; Self-monitoring (snyder, 1974): the following example is a study showing how self-monitoring of expressive behaviour is different across individuals. For some people we can quickly infer their traits while other are more chameleon-like.
