In research, the ecological validity of a study means that the methods, materials and setting of the study must approximate the real-world that is being examined. Unlike internal and external validity, ecological validity is not necessary to the overall validity of a study.
Concurrent validity is one of the two types of criterion-related validity. Criterion-related validity refers to the degree to which a measurement can accurately predict specific criterion variables.ince the construct, or psychological concept, that you want to measure is depression, you search for psychological tests that measure depression. In your search, you come across the Beck Depression Inventory, which researchers have determined through several studies is a valid measure of depression.
