Reliability refers to the extent to which test scores, if a test were administered to a sample twice within a short period of time, would be similar in both administrations. Test validity refers to evidence that a test measures the [[Construct (philosophy)|construct]] (e.g., neuroticism) that it is supposed to measure.<ref>{{cite book|last1=Urbina|first1=Susana|title=Essentials of Psychological Testing|date=2014-06-30|publisher=John Wiley & Sons, Incorporated|location=Hoboken.
