Abstract Title: Establishing Reliability and Validity: an Ongoing Process
Abstract: Establishing validity and reliability is a necessary step in any conceptual assessment instrument.  But once validity and reliability are established, it is not the end of the story.  Reliability and validity are not an inherent property of the assessment instrument or its individual items, but something that must be reestablished with any changes of the instrument items, order, administration techniques or population being studied.   In this paper we will discuss how validity and reliability can be established or reestablished.  We will also discuss common instances in instrument development and use that requires reliability and validity to be reestablished.
