Document Summary

Validity: a reliable measure is useless unless valid, establishing validity of abstract constructs can be a lengthy process. Face validity is this a plausible measure of my construct: not empirical, can change over time, 2. Content validity have i covered everything: measuring attempting to get a different parts of a construct. Convergent validity does measure correlates with other measures of the same construct; should be relatively positively correlated: segal on convergent validity of bdi-ll with ces-d in older population, circular reasoning; basing validity of one measure on another. Discriminate validity is the measure correlated with something it"s not meant to measure: come up with things you"re worried you"re accidentally measuring with your measure, choosing your discriminant validity measures, ex. Convert research goals into a list of specific topics: 2. Develop your items: practical limitations, order of items, clarity of items, content validity of items, 3. Is there trouble with the items: 4.
