Therefore, reliability, validity and triangulation, if they are relevant research concepts, particularly from a qualitative point of view, have to be redefined in order to reflect the multiple ways of establishing truth. It can be divided into a population and ecological validities (“Threats to Internal & External Validity.,” n.d.). Clinical psychologists often believe that research psychologists spend all of their time in laboratories, testing mice and humans in conditions that bear little resemblance to the outside world.
