Construct validity refers to the degree to which inferences can legitimately be made from the operationalizations in your study to the theoretical constructs on which those operationalizations were based. Test validity is the degree to which the test measures what it intends to measure, and can be further broken down into categories. External validity indicates the level to which findings are generalized.
