Document Summary

Operationalization- measurement of something not directly measurable (translation of an idea or construct into something real and concrete) Validity-the best available approximation of the truth of a given proposition, inference, or conclusion. External validity- degree to which study conclusions hold for other people in other places at other times. Construct validity: approximate truth of conclusion that operationalization accurately reflects its construct (generalizing from program or measures to the concept or idea of your program or measures) Assessment of how well your actual programs or measures reflect your ideas or theories. Land of theory: what goes on inside mind and attempt to explain to others (about theories, ideas, hunches, hypotheses about the world) Ether you have operationalized the construct correctly or you haven"t (either-or type thinking: relationalist perspective- things are not either/or (black or white) concepts are more or less related to each other. Translation validity-focuses on whether operationalization is a good translation of the construct.
