reliability estimate of the current test; and m equals the new test length divided by the old test length. For example, if the test is increased from 5 to 10 items, m is 10 / 5 = 2. Consider the reliability estimate for the five-item test used previously (α=ˆ .54). If the test is doubled to include 10 items, the new reliability estimate would be

Chapter 3 Psychometrics: Reliability & Validity

Reliability is an indicator of consistency, i.e., an indicator of how stable a test score or data is across applications or time. A measure should produce similar or the same results consistently if it measures the same “thing.” A measure can be reliable without being valid. A measure cannot be valid with
